ABSTRACT:
The disclosed invention relates to an auxiliary feed mechanism adapted to maintain an edge of a workpiece in substantial registration with a predetermined path along which the workpiece edge is moved. The invention includes a motor driven auxiliary feed device which is operatively associated with a unique servosystem. The invention further includes sensing elements arranged to monitor the position of the workpiece edge and devices operatively associated with the sensing elements and the servosystem for automatically adjusting the feed rate of the auxiliary mechanism according to the characteristics of the work being sewn and for effecting the speed of the auxiliary mechanism relative to the velocity of the workpiece whereby maintaining the desired alignment of the workpiece edge relative its predetermined position or path during the sewing operation.
