Abstract
A method of fabricating heating structures in which a heating wire having a thermoplastic outer layer is arranged in a predetermined pattern and one or more strands of thermoplastic material are applied to the individual sections and bonded thereto. The area near the bond is heated to a temperature sufficient to fuse the surfaces of the wire and strand or strands and, after the wire and strands have cooled, the strands adhere to the sections, thus forming an integrated heating structure from the separate heating wire sections and thermoplastic strands. The sections may be parallel to one another and the strands applied thereto in substantially right angle relationship, and when a number of strands are applied to the wire sections, they normally are applied simultaneously and in parallel relation.
