Abstract
An apparatus is provided having a continuous band of material passing through the stitching means of a sewing machine. Pieces of material are manually placed individually on the band and hemmed to it at a side which has been folded under the band by a mechanical folder. A sensing means senses the passage of an end of each piece which has had a portion raised from the band and in response activates a cutter which cuts away a strip of the band to which the piece was hemmed. A removal means for moving the strip away from the band and into a stacker is activated after the strip has been cut away from the band. The stacker has a base supporting two spaced, upwardly extending sidewalls defining a passage therebetween. Each of the sidewalls supports a ledge protruding into the passage. A portion of the base is vertically movable and adapted to fit within the space between the ledges. As the strip comes to rest in the passage, the movable portion of the base, upon being actuated by the sensing means, is raised above the ledges and then returned to its original position, leaving the strip resting on the ledges.
