Abstract
An ultrasonic horn cooperates with a cutting wheel and two stitching wheels to simultaneously cut, seal and stitch thermoplastic material. The cutting and stitching wheels are urged towards the ultrasonic horn by a spring biased pivot arm upon which the wheels are rotatably mounted. The combination of ultrasonic horn, wheels and pivot arm define a cutting assembly. The entire cutting assembly is connected to the reciprocating rod of a piston which alternately lowers the cutting assembly into a cutting position wherein the material to be cut is located between the horn tip and the wheels, and raises the cutting assembly into a return position wherein the material to be cut is below and out of contact with the cutting assembly.
