Abstract: A device for sewing together two plies of cloth with a lap seam. The device comprises a cloth guide that is disposed between a plurality of reciprocating needles and the front of a cutting knife. The guiding portion of the cloth guide extends substantially between the needles and the front edge of the cutting knife. A cloth guide for assuring a full lap of material when sewing a lap seam where the left ply is to be laid on top of the right ply is also provided.

Abstract: A device for aligning the margin and leading edges of plies of material to be sewed and locating the aligned edges at the stitch forming location of a sewing machine. A first sensor for detecting the presence of the work piece and actuating a power driven gripper wheel in response to sensing the work piece. The power driven gripper wheel moves the work piece toward a second sensor that detects the work piece's margin edge and stops the power driven gripper wheel and actuates a power driven feeding wheel that feeds the work piece toward the stitch forming location. A third sensor detects the leading edge of the work piece as it approaches the stitch forming location. Control mechanisms are provided for commencing the sewing operation when the work material is at the stitch forming location.

Abstract: A device for picking up, turning over, folding and aligning a sleeve cloth that is continuously carried by a moving conveyer. The device comprises a jaw located above the upper surface of the moving conveyer and a lifting blade located below the bottom surface of a moving conveyer. The leading edge of the sleeve cloth is detected by a sensor that triggers the lifting blade to push a front portion of the cloth up and into the jaw which holds the cloth as the conveyer continues to move. The cloth is folded and aligned by the action of the conveyor belt and a first blower, which blows air on a top side of the cloth, and a second blower, which blows air on a bottom side of the cloth.

Abstract: An apparatus for and method of attaching an elastic band to the body of a garment is provided. The workpieces are monitored and aligned during the attachment process by sensors and guide mechanisms, electrically coupled to a controller that facilitates the activities, while a tensioning mechanism maintains the workpieces in a desired configuration. The use of the apparatus and method results in an efficient and automatic process of attachment that eliminates the need for an operator to manually align and guide the workpieces through the sewing instrumentality.

Abstract: A looper throw-out device containing a latch for catching the release lever of the looper throw-out device when the release lever is left in the unlocked position. The latch is mounted on the inside portion of the sewing machine cover. If an operator fails to lock the release lever before sewing, the latch catches the unlocked release lever when the operator attempts to close the sewing machine cover.
