Abstract
A discharge and cutting apparatus for attachment to the trailing end of a tandem sewing machine, which is used to sew footwear components and apply tape to the seam, includes a frame having a base plate contiguous with the work surface of the sewing machine for receiving the footwear components interconnected by the continuous strip of tape, a pair of opposed pressure rollers for drawing the components and tape from the sewing machine, a smaller pressure roller driven in synchronism with the first pressure rollers for maintaining the components and tape under tension, a cutting device including an electromagnetically operated blade for chopping the tape at the leading and trailing edges of the components, and a second pair of opposed small pressure rollers for receiving the components and tape from the cutting operation and discharging the components and tape from the apparatus. A transmission interconnecting all of the rollers and the sewing machine drive ensures that the pressure rollers are driven in synchronism with the sewing machine and with each other. By reducing the size and thus increasing the rotational speed of the pressure rollers in the direction of travel of the tape and components, the material being treated is kept under constant tension during discharge and cutting.
