Stretchable belt conveyor system and belt construction.

摘要

A belt conveyor system has a stretchable belt reinforced by a layer of stretch fabric (16) which includes crimped high strength warp cords (17) woven around transverse cords (18). Low strength warp cords (19) are woven around the transverse cords (18) in an opposite direction to hold the high strength cords (17) in the crimped condition prior to and during molding of the belt. Upon installation the belt is stretched at least 5 percent and the low strength warp cords (19) are broken. The high strength warp cords (17) are then straightened out which results in a substantial increase in the resistance of the belt to further stretching after installation on the conveyor.
