ABSTRACT:
An apparatus for cutting and sealing the cut edges of semipermeable and at least partially thermoplastic fabric material is disclosed as having a support to position the material for cutting and sealing, a vacuum system to secure the material to the support to immobilize the material while the latter is being cut and sealed, an ultrasonic cutter to cut the material and to seal cut edges to prevent raveling thereof, and a guide to direct the cutter to cut the material in a desired configuration. The apparatus may be particularly adapted to cut and seal cut edges of automotive safety air bag material.
