ABSTRACT:
A device and method for linearly inserting an interlining into the formation of a waistband of a garment such as slacks. The device has separate guiding means which directs different strips of fabric into a sewing mechanism which, in turn, combines the waistband components. One of the fabrics constitutes the interlining which prevents the waistband from rolling over in use. The guide for feeding the interlining into the sewing mechanism utilizes a linearly moving air cylinder. Pins on a holder pivotally connected to the cylinder attach to the interlining and feed it directly into the sewing mechnism. As a result, the pins and the interlining move linearly toward the sewing mechanism. As the cylinder returns to its starting position, the holder pivots to release the pins from the material to avoid pulling the interlining away from the sewing mechanism. Lastly, a knife connects to a second cylinder through a chain link. After the inclusion of the desired amount of interlining in the waistband, the knife severs the former. The two cylinders operate under the control of a foot pedal. Pressing the pedal the first time inserts the lining into the sewing mechanism and pressing it a second time cuts the interlining.
