ABSTRACT:
Apparatus and method for cutting a piece of synthetic fibrous material to a desired shape is disclosed. The apparatus includes an elongate heat resistive mounting structure having a shape conforming at least partially to the curvature of the desired shape. The mounting structure has an exposed face, and a resistor wire is embedded in this exposed face. Electric power is applied to the resistor wire so that the wire in the heat resistive mounting is heated to melt the synthetic fibrous material as the mounting structure is moved therethrough to cut the material to the desired shape.
