ABSTRACT:
A machine for automatically aligning cut sleeve blanks after they are manually placed on the conveying surface by the operator. A material presence sensor is provided that recognizes the leading edge of the cut sleeve blank as it is being fed toward the hemming machine. Recognition of the leading edge of the sleeve blank causes an edge guider and blowers to be activated. An edge sensor is provided that senses the location of the marginal edge of the sleeve blank relative to the stitch line and sends signals that are conveyed to the edge guider. The edge guider maintains the marginal edge of the sleeve blank a predetermined distance from the stitch line. Air jets are directed on the upper surface of the sleeve blank to maintain it flat during the aligning process. The leading edge of the cut shirt blank is captured by a driven top belt conveyor which functions to maintain control of the sleeve blank.
