Abstract
A conveyor system for use in processing lengths of flexible material in which the conveyor system is formed of a pair of parallel spaced chains adapted to be displaced longitudinally and carrying a plurality of gripping devices positioned to successively receive lengths of flexible material from a source thereof. The lengths of flexible material are conveyed in an intermittent fashion to permit various work operations to be performed on the successive lengths of flexible material. The gripping devices include a body member fixed to the conveyor having a notch therein adapted to receive a cross section of the lengths of flexible material, and a lever pivotally mounted on the body member and having a arcuate surface adapted to secure the lengths of flexible material in the notch of the body member. The conveyor system also includes discharge equipment including an elongate bar extending longitudinally between the gripping devices at one end of the conveyor system, and including means to release the lengths of flexible material from the gripping devices as the gripping devices advance the lengths of flexible material over the bar whereby the lengths of flexible material are bent over …
