Accounting Changes And Error Corrections [Abstract]
Recently Issued Accounting Standards	2. Recently issued accounting standards New accounting guidance adopted: In March 2016, the Financial Accounting Standards Board (“FASB”) issued a new standard which simplifies the accounting for share-based payment transactions. This guidance requires that excess tax benefits and tax deficiencies be recognized as income tax expense or benefit in the statements of income rather than additional paid-in capital. Additionally, the excess tax benefits will be classified along with other income tax cash flows as an operating activity, rather than a financing activity, in the statements of cash flows. Further, the update allows an entity to make a policy election to recognize forfeitures as they occur or estimate the number of awards expected to be forfeited. We adopted this new standard during the first quarter of 2018. As a result, net excess tax benefits of $6,950 were recognized as a reduction of income tax expense during the six months ended April 30, 2018. The cash flow classification requirements of this new standard were applied retrospectively. As a result, excess tax benefits of $6,950 are reported as Net cash provided by operating activities for the six months ended April 30, 2018 and $4,908 of excess tax benefits were reclassified from Net cash used in financing activities to Net cash provided by operating activities for the six months ended April 30, 2017. This new standard also requires that employee taxes paid when an employer withholds shares for tax-withholding purposes be reported as financing activities in the statements of cash flows on a retrospective basis. Previously, this activity was included in operating activities. The impact of this change was immaterial to the statements of cash flows. Additionally, we elected to continue to estimate forfeitures rather than account for them as they occur. New accounting guidance issued and not yet adopted: In May 2014, the Financial Accounting Standards Board (“FASB”) issued a new standard regarding revenue recognition. Under this standard, a company recognizes revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The standard implements a five-step process for customer contract revenue recognition that focuses on transfer of control. In August 2015, the FASB issued a standard to delay the effective date by one year. The new standard is effective for us beginning November 1, 2018. The new standard is required to be applied retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of initially applying it recognized at the date of initial application (modified retrospective method). We have not yet selected a transition method; however, we are currently anticipating using the modified retrospective method, but will base the final decision on the results of our assessment once complete. Our initial analysis of identifying revenue streams and evaluating a representative sample of contracts and other agreements with our customers is complete. We are in the process of assessing the impact of the new standard, if any, on our business processes, systems and controls. We will finalize our evaluation of potential differences that may result from applying the new standard to our contracts with customers in 2018 and provide updates on our progress in future filings. In February 2016, the FASB issued a new standard which requires a lessee to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases with a lease term of more than twelve months. Leases will continue to be classified as either financing or operating, with classification affecting the recognition, measurement and presentation of expenses and cash flows arising from a lease. It will be effective for us beginning November 1, 2019. We are currently assessing the impact this standard will have on our consolidated financial statements. In March 2017, the FASB issued a new standard which requires the presentation of the service cost component of the net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period. All other components of net periodic benefit cost will be presented below operating income. Additionally, only the service cost component will be eligible for capitalization in assets. It will be effective for us beginning November 1, 2018. Early adoption is permitted. We are currently assessing the impact this standard will have on our consolidated financial statements. In February 2018, the FASB issued a new standard which gives entities the option to reclassify tax effects stranded in accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act (“the Act”) into retained earnings. The guidance allows entities to reclassify from accumulated other comprehensive income to retained earnings stranded tax effects resulting from the Act's new federal corporate income tax rate. The guidance also allows entities to elect to reclassify other stranded tax effects that relate to the Act but do not directly relate to the change in the federal tax rate (e.g., state taxes, changing from a worldwide tax system to a territorial system). Tax effects that are stranded in accumulated other comprehensive income for other reasons (e.g., prior changes in tax law, a change in valuation allowance) may not be reclassified. It will be effective for us beginning November 1, 2019. Early adoption is permitted. We are currently assessing the impact this standard will have on our consolidated financial statements. In March 2018, the FASB issued a new standard which adds various Securities and Exchange Commission (“SEC”) paragraphs pursuant to the issuance of the December 2017 SEC Staff Accounting Bulletin No. 118 (“SAB 118”), Income Tax Accounting Implications of the Tax Cuts and Jobs Act , which was effective immediately. The SEC issued SAB 118 to address concerns about reporting entities’ ability to timely comply with the accounting requirements to recognize all of the effects of the Act in the period of enactment. SAB 118 allows disclosure that timely determination of some or all of the income tax effects from the Act are incomplete by the due date of the financial statements and if possible to provide a reasonable estimate. We have accounted for the tax effects of the Act under the guidance of SAB 118, on a provisional basis. Our accounting for certain income tax effects is incomplete, but we have determined reasonable estimates for those effects and have recorded provisional amounts in our consolidated financial statements. Refer to Note 7 for additional information.

Acquisitions	3. Acquisitions 2018 acquisition On January 2, 2018, we purchased 100 percent of the outstanding shares of Sonoscan, Inc. (“Sonoscan”), an Elk Grove Village, Illinois leading designer and manufacturer of acoustic microscopes and sophisticated acoustic micro imaging systems used in a variety of microelectronic, automotive, aerospace and industrial electronic assembly applications. We acquired Sonoscan for an aggregate purchase price of $44,832, net of $656 of cash. Based on the fair value of the assets acquired and the liabilities assumed, goodwill of $21,363 and identifiable intangible assets of $7,910 were recorded. The identifiable intangible assets consist primarily of $1,700 of customer relationships (amortized over 7 years), $3,300 of tradenames (amortized over 11 years), $2,500 of technology (amortized over 7 years) and $410 of non-compete agreements (amortized over 5 years). Goodwill associated with this acquisition is tax deductible. This acquisition is being reported in our Advanced Technology Systems segment. As of April 30, 2018, the purchase price allocations remain preliminary as we complete our assessments of income taxes, intangible assets and certain reserves. 2017 acquisition On March 31, 2017, we completed the acquisition designer, developer and manufacturer of minimally invasive interventional delivery devices, catheters and advanced components for the global medical technology market. This is a highly complementary business that adds significant scale and enhances strategic capabilities of our existing medical platform. We acquired Vention for an aggregate purchase price of $705,000, net of $3,313 of cash and other closing adjustments of $10,726. The acquisition was funded primarily through a new term loan facility, as well as through cash and borrowings on our credit facility. The purchase price was allocated to the underlying assets acquired and liabilities assumed based upon their estimated fair values at the date of acquisition. We determined the estimated fair values based on independent appraisals, discounted cash flow analyses, quoted market prices, replacement cost analyses and estimates made by management. Based on the fair value of the assets acquired and the liabilities assumed, goodwill of $434,123, of which $37,200 is tax deductible, and identifiable intangible assets of $286,000 were recorded. The identifiable intangible assets consist primarily of $240,000 of customer relationships (amortized over 14 years), $2,000 of tradenames (amortized over 6 years), and $44,000 of technology, consisting of $36,000 (amortized over 14 years) and $8,000 (amortized over 10 years). Also on March 31, 2017, we entered into a $705,000 term loan facility with a group of banks. The Term Loan Agreement provides for the following term loans in three tranches: $200,000 due in September 2018, $200,000 due in March 2020, and $305,000 due in March 2022. The weighted average interest rate for borrowings under this agreement was 2.99% at April 30, 2018. Borrowings under this agreement were used for the single purpose of acquiring Vention. We were in compliance with all covenants at April 30, 2018.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	7. Income taxes We record our interim provision for income taxes based on our estimated annual effective tax rate, as well as certain items discrete to the current period. The effective tax rates for the three and six months ended April 30, 2018 were 22.8% and 11.7%, respectively. The effective tax rates for the three and six months ended April 30, 2017 were 31.8% and 30.6%, respectively. The Act was enacted into law on December 22, 2017. It reduces the U.S. federal corporate income tax rate from 35% to 21%. We have an October 31 fiscal year-end, therefore the lower corporate income tax rate will be phased in, resulting in a U.S. statutory federal rate of 23.3% for our fiscal year ending October 31, 2018, and 21% for subsequent fiscal years. The statutory tax rate of 23.3% was applied to earnings in the current quarter. The Act requires us to revalue our existing U.S. deferred tax balance to reflect the lower statutory tax rate and pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously deferred from U.S. taxes. As a result, during the first quarter of 2018, we recorded a provisional tax benefit of $45,213 to reflect the revaluation of our tax assets and liabilities at the reduced corporate tax rate. We also recorded a provisional tax expense of $23,124 to reflect the transition tax on previously deferred foreign earnings. The net tax effect of these discrete items resulted in a decrease of $22,089 in income tax expense for the six months ended April 30, 2018. We intend to pay the transition tax in installments over the eight year period allowable under the Act. The transition tax is primarily included in other long-term liabilities in the Consolidated Balance Sheet at April 30, 2018. The amounts recorded are considered a provisional estimate under the U.S. Securities and Exchange Commission Staff Accounting Bulletin No. 118. The provisional calculations may change after the underlying temporary differences and foreign earnings are finalized. Furthermore, we are still analyzing certain aspects of the Act and related interpretive guidance and refining our calculations which could potentially affect the measurement of these balances or potentially give rise to new or additional deferred tax amounts. In March 2016, the FASB issued a new standard which simplifies the accounting for share-based payment transactions, which we adopted in the first quarter of 2018. This guidance requires that excess tax benefits and tax deficiencies be recognized as income tax expense or benefit in the Consolidated Statements of Income rather than as additional paid-in capital. As a result, our income tax provision for the three and six months ended April 30, 2018 includes a discrete tax benefit of $2,202 and $6,950, respectively. During the three months ended April 30, 2017, we recorded a discrete tax expense of $2,600 related to nondeductible acquisition costs.

Stock-Based Compensation	9 . Stock-based compensation During the 2018 Annual Meeting of Shareholders, our shareholders approved the Amended and Restated 2012 Stock Incentive and Award Plan (the “2012 Plan”). The 2012 Plan provides for the granting of stock options, stock appreciation rights, restricted shares, restricted share units, performance shares, cash awards and other stock or performance-based incentives. A maximum of 4,525 common shares is available for grant under the 2012 Plan. Stock Options Nonqualified or incentive stock options may be granted to our employees and directors. Generally, options granted to employees may be exercised beginning one year from the date of grant at a rate not exceeding 25 percent per year and expire 10 years from the date of grant. Vesting accelerates upon a qualified termination in connection with a change in control. In the event of termination of employment due to early retirement or normal retirement at age 65, options granted within 12 months prior to termination are forfeited, and vesting continues post retirement for all other unvested options granted. In the event of disability or death, all unvested stock options granted within 12 months prior to termination (or at any time prior to December 28, 2017) fully vest. Termination for any other reason results in forfeiture of unvested options and vested options in certain circumstances. The amortized cost of options is accelerated if the retirement eligibility date occurs before the normal vesting date. Option exercises are satisfied through the issuance of treasury shares on a first-in, first-out basis. We recognized compensation expense related to stock options of $2,454 and $2,312 in the three months ended April 30, 2018 and 2017, respectively. Corresponding amounts for the six months ended April 30, 2018 and 2017 were $5,071 and $4,634, respectively. The following table summarizes activity related to stock options for the six months ended April 30, 2018: Number of Options Weighted-Average Exercise Share Aggregate Intrinsic Value Weighted Average Remaining Term Outstanding at October 31, 2017 1,922 $ 70.08 Granted 368 $ 127.67 Exercised (319 ) $ 48.94 Forfeited or expired (5 ) $ 95.48 Outstanding at April 30, 2018 1,966 $ 84.21 $ 87,282 6.9 years Vested or expected to vest at April 30, 2018 1,944 $ 83.83 $ 87,036 6.9 years Exercisable at April 30, 2018 1,023 $ 65.54 $ 64,539 5.4 years As of April 30, 2018, there was $12,874 of total unrecognized compensation cost related to unvested stock options. That cost is expected to be amortized over a weighted average period of approximately 1.5 years. The fair value of each option grant was estimated at the date of grant using the Black-Scholes option-pricing model with the following assumptions: Six months ended April 30, 2018 April 30, 2017 Expected volatility 24.0%-26.7% 26.0%-29.2% Expected dividend yield 0.97% 0.91%-1.17% Risk-free interest rate 2.09%-2.20% 1.89%-2.06% Expected life of the option (in years) 5.4-6.2 5.4-6.2 The weighted-average expected volatility used to value the 2018 and 2017 options was 25.0% and 29.1%, respectively. Historical information was the primary basis for the selection of the expected volatility, expected dividend yield and the expected lives of the options. The risk-free interest rate was selected based upon yields of U.S. Treasury issues with a term equal to the expected life of the option being valued. The weighted average grant date fair value of stock options granted during the six months ended April 30, 2018 and 2017 was $31.42 and $28.86, respectively. The total intrinsic value of options exercised during the three months ended April 30, 2018 and 2017 was $11,021 and $6,806, respectively. The total intrinsic value of options exercised during the six months ended April 30, 2018 and 2017 was $29,744 and $19,256, respectively. Cash received from the exercise of stock options for the six months ended April 30, 2018 and 2017 was $15,595 and $12,040, respectively. Restricted Shares and Restricted Share Units We may grant restricted shares and/or restricted share units to our employees and directors. These shares or units may not be transferred for a designated period of time (generally one to three years) defined at the date of grant. For employee recipients, in the event of termination of employment due to early retirement with the consent of the Company, restricted shares granted within 12 months prior to termination are forfeited, and other restricted shares vest on a pro-rata basis. In the event of termination of employment due to normal retirement at age 65, restricted shares granted within 12 months prior to termination are forfeited, and, for other restricted shares, the restriction period will lapse and the shares will vest and be transferable. For restricted shares granted within 12 months prior to termination (or at any time prior to December 28, 2017), the restrictions lapse in the event of a recipient’s disability or death. Termination for any other reason prior to the lapse of any restrictions results in forfeiture of the shares. For non-employee directors, all restrictions lapse in the event of disability or death of the non-employee director. Termination of service as a director for any other reason within one year of date of grant results in a pro-rata vesting of shares or units. As shares or units are issued, deferred stock-based compensation equivalent to the fair value on the date of grant is expensed over the vesting period. Tax benefits arising from the lapse of restrictions are recognized when realized and credited to capital in excess of stated value. The following table summarizes activity related to restricted shares during the six months ended April 30, 2018: Number of Shares Weighted-Average Grant Date Fair Value Restricted shares at October 31, 2017 58 $ 90.38 Granted 20 $ 127.68 Vested (23 ) $ 84.78 Restricted shares at April 30, 2018 55 $ 106.33 As of April 30, 2018, there was $4,058 of unrecognized compensation cost related to restricted shares. The cost is expected to be amortized over a weighted average period of 2.0 years. The amount charged to expense related to restricted shares during the three months ended April 30, 2018 and 2017 was $637 and $510, respectively. These amounts included common share dividends for the three months ended April 30, 2018 and 2017 of $17 and $15, respectively. For the six months ended April 30, 2018 and 2017, the amounts charged to expense related to restricted shares were $1,391 and $1,088, respectively. These amounts included common share dividends for the six months ended April 30, 2018 and 2017 of $34 and $31, respectively. The following table summarizes activity related to restricted share units during the six months ended April 30, 2018: Number of Units Weighted-Average Grant Date Fair Value Restricted share units at October 31, 2017 0 $ — Granted 8 $ 126.38 Restricted share units at April 30, 2018 8 $ 126.38 As of April 30, 2018, there was $500 of remaining expense to be recognized related to outstanding restricted share units, which is expected to be recognized over a weighted average period of 0.5 years. The amount charged to expense related to restricted share units during each of the three months ended April 30, 2018 and 2017 was $252 and $253, respectively. For the six months ended April 30, 2018 and 2017, the corresponding amounts were $505 and $506, respectively. Deferred Directors’ Compensation Non-employee directors may defer all or part of their cash and equity-based compensation until retirement. Cash compensation may be deferred as cash or as share equivalent units. Deferred cash amounts are recorded as liabilities, and share equivalent units are recorded as equity. Additional share equivalent units are earned when common share dividends are declared. The following table summarizes activity related to director deferred compensation share equivalent units during the six months ended April 30, 2018: Number of Shares Weighted-Average Grant Date Fair Value Outstanding at October 31, 2017 101 $ 46.74 Dividend equivalents 1 $ 141.77 Outstanding at April 30, 2018 102 $ 47.14 The amount charged to expense related to director deferred compensation for the three months ended April 30, 2018 and 2017 was $30 and $26, respectively. For the six months ended April 30, 2018 and 2017, the corresponding amounts were $61 and $52, respectively. Performance Share Incentive Awards Executive officers and selected other key employees are eligible to receive common share-based incentive awards. Payouts, in the form of unrestricted common shares, vary based on the degree to which corporate financial performance exceeds predetermined threshold, target and maximum performance goals over three-year performance periods. No payout will occur unless threshold performance is achieved. The amount of compensation expense is based upon current performance projections for each three-year period and the percentage of the requisite service that has been rendered. The calculations are also based upon the grant date fair value determined using the closing market price of our common shares at the grant date, reduced by the implied value of dividends not to be paid. The per share values were $123.45 for 2018, $103.75 and $104.49 per share for 2017 and $67.69 per share for 2016. During the three months ended April 30, 2018 and 2017, $1,637 and $3,178 was charged to expense, respectively. For the six months ended April 30, 2018 and 2017, the corresponding amounts were $4,986 and $3,430, respectively. The cumulative amount recorded in shareholders’ equity at April 30, 2018 was $12,108. Deferred Compensation Our executive officers and other highly compensated employees may elect to defer up to 100% of their base pay and cash incentive and for executive officers, up to 90% of their share-based performance incentive payout each year. Additional share units are credited for quarterly dividends paid our common shares. Expense related to dividends paid under this plan for the three months ended April 30, 2018 and 2017 was $67 and $68, respectively. For the six months ended April 30, 2018 and 2017, the corresponding amounts were $134 and $129, respectively.

Warranties	10. Warranties We offer warranties to our customers depending on the specific product and terms of the customer purchase agreement. A typical warranty program requires that we repair or replace defective products within a specified time period (generally one year) from the date of delivery or first use. We record an estimate for future warranty-related costs based on actual historical return rates. Based on analysis of return rates and other factors, the adequacy of our warranty provisions are adjusted as necessary. The liability for warranty costs is included in accrued liabilities in the Consolidated Balance Sheet. Following is a reconciliation of the product warranty liability for the six months ended April 30, 2018 and 2017: April 30, 2018 April 30, 2017 Beginning balance at October 31 $ 13,377 $ 11,770 Accruals for warranties 5,937 5,148 Warranty assumed from acquisitions - 61 Warranty payments (6,642 ) (4,821 ) Currency effect 227 2 Ending balance $ 12,899 $ 12,160

Segment Reporting [Abstract]
Operating Segments	11. Operating segments We conduct business across three primary business segments: Adhesive Dispensing Systems, Advanced Technology Systems, and Industrial Coating Systems. The composition of segments and measure of segment profitability is consistent with that used by our chief operating decision maker. The primary measure used by the chief operating decision maker for purposes of making decisions about allocating resources to the segments and assessing performance is operating profit, which equals sales less cost of sales and certain operating expenses. Items below the operating profit line of the Consolidated Statement of Income (interest and investment income, interest expense and other income/expense) are excluded from the measure of segment profitability reviewed by our chief operating decision maker and are not presented by operating segment. The accounting policies of the segments are the same as those described in Note 1, Significant Accounting Policies, of our annual report on Form 10-K for the year ended October 31, 2017. The following table presents information about our segments: Adhesive Advanced Industrial Corporate Total Three months ended April 30, 2018 Net external sales $ 238,775 $ 250,839 $ 64,092 $ — $ 553,706 Operating profit (loss) 69,514 (a) 58,306 11,572 (12,687 ) 126,705 Three months ended April 30, 2017 Net external sales $ 226,943 $ 210,142 $ 59,052 $ — $ 496,137 Operating profit (loss) 65,719 (b) 54,306 10,252 (26,746 ) 103,531 Six months ended April 30, 2018 Net external sales $ 459,639 $ 522,540 $ 121,951 $ — $ 1,104,130 Operating profit (loss) 122,829 (a) 125,574 21,732 (25,707 ) 244,428 Six months ended April 30, 2017 Net external sales $ 434,780 $ 355,502 $ 113,325 $ — $ 903,607 Operating profit (loss) 118,775 (b) 80,669 17,337 (37,332 ) 179,449 (a) Includes $1,082 and $2,149 of severance and restructuring costs in the three and six months ended April 30, 2018, respectively.

Investments All Other Investments [Abstract]
Financial Instruments	13. Financial instruments We operate internationally and enter into intercompany transactions denominated in foreign currencies. Consequently, we are subject to market risk arising from exchange rate movements between the dates foreign currencies are recorded and the dates they are settled. We regularly use foreign currency forward contracts to reduce our risks related to most of these transactions. These contracts usually have maturities of 90 days or less and generally require us to exchange foreign currencies for U.S. dollars at maturity, at rates stated in the contracts. These contracts are not designated as hedging instruments. We do not use financial instruments for trading or speculative purposes. Gains and losses on foreign currency forward contracts are recorded in “Other – net” on the Consolidated Statement of Income together with the transaction gain or loss from the hedged balance sheet position. For the three months ended April 30, 2018, we recognized losses of $1,607 on foreign currency forward contracts and gains of $2,584 from the change in fair value of balance sheet positions. For the three months ended April 30, 2017, we recognized losses of $1,687 on foreign currency forward contracts and gains of $702 from the change in fair value of balance sheet positions. For the six months ended April 30, 2018, we recognized losses of $2,571 on foreign currency forward contracts and gains of $1,602 from the change in fair value of balance sheet positions. For the six months ended April 30, 2017, we recognized losses of $1,900 on foreign currency forward contracts and gains of $906 from the change in fair value of balance sheet positions.
