Abstract
A method and apparatus are provided for acting upon a cloth in a manner for automatically forming a shirt sleeve from a sleeve blank. The blank is conveyed by a conveyor is a first direction and a hem is automatically formed and secured along a longitudinal edge thereof. The blank is automatically picked up off the conveyor and folded about an axis substantially transverse to the first direction. The transference of the hemmed and folded sleeve is controlled such that the overlapping edges of the folded blank are in substantial alignment relative to one another when deposited on a second conveyor which conveys the blank in a second direction. As the blank is conveyed by the second conveyor, the overlapping and generally aligned edges of the folded workpiece are secured together to form a shirt sleeve.
