Abstract
A machine for fabricating heating structures having heating wires with an external layer of thermoplastic material arranged with sections in a predetermined pattern, and carrier strands of thermoplastic material fused to and interconnecting the wire sections. The machine includes a wire support means having laterally spaced pegs or the like on which the wire is retained in a predetermined configuration on a substantially common plane. A heating unit or units simultaneously heat the carrier strands and wire sections together. The heating elements and wire configuration are moved relative to one another to join progressively the strands to the transversely arranged heating wire sections. The element used in the heating unit includes a guide trough for the carrier strands and simultaneously heats facing surfaces of the strands and heating wire so that the two can be pressed together while fused to form the bond. The invention also includes the method having the steps of heating the strands and heating wire and pressing the two together, while the two have facing fused areas, to form a bond between the strands and the heating wire.
