ABSTRACT:
An apparatus for picking up and feeding, one by one, workpieces which are stacked in a guide, such as shirt cuffs or the like having an inconsistent thickness. A pair of delivery rollers is rotated so as to slacken the lowermost workpiece so that the latter is readily drawn from the guide by a pickup means for supply to an automatic sewing station.
