Conveyor Belt Carcass Containing One or More Impregnated Non-woven Fabric Layers
6 Jan 22
A belt carcass (1) comprising one, two, or more than two impregnated layers (21,22,23,24,25); characterised in that i) each impregnated layer (21,22,23,24,25) comprises, or consists essentially of, a non-wovenfabric (3,301,302,303,304,305,306,307,308) and an impregnation material (4,401,402,403,404,405,406,407,408) comprising, or consisting essentially of, a first thermoplastic, first thermoplastic elastomer, first elastomer or first thermoset and optional additives; whereby, if there are two or more such impregnated layers (21,22,23,24,25), they are adjacent to each other, ii) if the belt carcass (1) comprises one or more such impregnated layers (21,22,23,24,25), then reinforcing filaments extending at least in part in one given direction and being in the form of one filament layer (51) are embedded in the non-woven fabric (3) of exactly one of said impregnated layers (21); or if the belt carcass (1) comprises two or more such impregnated layers (21,22,23,24,25), then reinforcing filaments extending at least in part in one given direction and being in the form of one filament layer (52,53) are sandwiched between two adjacent such impregnated layers (21/22, 24/25), and iii) the belt carcass is devoid of woven fabrics.
