ABSTRACT:
The present invention relates to a novel method and apparatus for cutting small pieces of fabric by means of an ultrasonic horn and a hollow open centered cutting anvil. The cutting operation includes a pick mechanism incorporating two tapered pins and a stripper pad to maintain the fabric position before, during, and after the cutting operation. The pick head mechanism is designed to insure accuracy in locating these small fabric pieces, referred to as chips, in a subsequent assembly operation performed by the pick head.
The assembly operation relates to attachment of small pieces of fabric by means of two miniature ultrasonic horns. The horns are combined with a pick and place mechanism which incorporates two tapered pins and a stripper pad to maintain the fabric position during the manufacturing process. This pick and place head, when attached to a robotic arm, is designed to insure accuracy in locating these small fabric pieces repeatedly in a thermoplastic cartridge.
