Dunnage Conversion Machine and Method
30 Sep 20
A method of making a dunnage product includes the following steps: (a) converting a sheet stock material into a lower density strip of dunnage having a width and a height that is less than the width; and (b) cutting the strip of dunnage to form a discrete dunnage product of a desired length by cutting across less than the width of the strip of dunnage to maintain a connection between the strip of dunnage and the discrete dunnage product.

Utility
Dunnage Conversion Machine, Helically-crumpled Dunnage Product and Method
13 May 20
A machine for converting a sheet stock material into a relatively less dense dunnage product includes both (a) a helical pre-form assembly having a cylindrical mandrel with a longitudinal axis and a guide member for guiding the sheet stock material from a supply thereof into a helical path along and around the mandrel so as to form a helical pre-form that rotates around the longitudinal axis and advances parallel to the longitudinal axis; and (b) a restriction in the path of the pre-form that slows the advance and rotation of the pre-form past the restriction, the restriction causing the pre-form to retard longitudinal advancement, to twist upon itself, and to permanently deform as it moves past the restriction, thereby longitudinally and helically crumpling the pre-form.

Utility
Dunnage conversion machine jam-detection system and method
2 Mar 20
A jam-sensing method for a dunnage conversion machine includes the following steps: (a) converting a stock material into a relatively less dense dunnage material having characteristics that vary along the length of the dunnage material; (b) sensing the characteristics of the dunnage material; (c) generating a signal that varies as a function of the sensed characteristics; (d) monitoring the generated signal over time; and (e) generating a control signal when variation in the generated signal within a predetermined period is less than a predetermined amount, which would indicate a lack of movement of the material.
