Ultrasonic Cutting Tool

Edge fraying of fabrics made from thermoplastic materials can be eliminated, by cutting the fabrics with an ultrasonically vibrated cutting tool.

A tool 1 useful for cutting oil wicks is shown. It is formed with a sharp cutting edge 2 in the outline of the wick. The tool is attached by threaded portion 3 to the horn of a commercially available ultrasonic vibrator. Openings 5 maintain the cutting energy at the lower portion of the tool. When the tool edge is pressed against the fabric stock 4, vibratory energy simultaneously heats and cuts the fibers. The heating fuses the fiber ends to each other so that the threads are not free to unravel.
