NON-WOVEN BROACHING MATERIAL FOR LINING DIFFICULTLY COMBUSTIBLE RUBBERIZED OR POLYVINYLCHLORIDE FIBRES OF CONVEYER BELTS

摘要

The knit-sewn material for covering fire-resistant rubber or PVC belts is constructed in such a way that its surface represents a fibrous layer and two basic arrangements of yarns, preferably with a core of low thermal shrinkage, are permanently joined together by means of a synthetic filament or spun yarn, advantageously of low thermal shrinkage. The material is used for manufacturing conveyor belts, chiefly PVC conveyor belts intended for underground mining.
