AT301B Pnuematic cut-a-part knife.
Electronic controls and electronic motor for manual elastic insertion and stitch counting with automatic stop and cut program.
The operator heels the treadle to lift the presser foot, presents the garment under the foot and sews to a predetermined point (notch, mark, pocket hem, etc.). Pressing the knee switch activates the feed cycle which momentarily lifts the presser foot and tension bar for elastic insertion. As sewing continues the elastic is automatically metered. Approximately 2" from the point where elastic is to end the operator activates the toe switch and cuts the elastic. Continuation of sew draws the elastic from the metering device as the waistband is completed. Side spot of 3" to full pocket-to-pocket elastic is attainable.
Most industrial multi-needle machines.
