Cloth moving type pile forming apparatus

Abstract

A pile forming apparatus of the type where piles are formed in cloth through movement of the cloth between a first position wherein piles are formed and a second position wherein piles are not formed. The apparatus includes a driving mechanism operated in synchronism with rotation of the main shaft of a loom, a transmission mechanism, and a cloth moving device, wherein the motion of the driving mechanism is transmitted to the cloth moving member by the transmission mechanism. The transmission mechanism includes a pair of swing levers connected with each other by a connection body such that the connecting position therebetween is made variable. One of paired swing levers is driven by the driving mechanism and the other is coupled with the cloth moving member. The connecting position between at least one of paired swing levers and the connection body is changed from at least the first position corresponding to an effective lever length enabling piles to be formed, to the second position corresponding to the effective lever length unable to form any pile, or vice versa according to a weaving plan or design. The connection between the swing levers and the driving mechanism enable the driving mechanism to receive and withstand the load applied to the entire system.
