Molded assembly with heating element captured therein
First Claim
1. A method of manufacturing a heated element assembly, comprising the steps of:
- (a) providing a first molded section;
(b) providing a second molded section shaped to mate with said first molded section;
(c) providing a resistance heating element, comprising;
(i) a supporting substrate having a first surface thereon; and
(ii) an electrical resistance heating material fastened to said supporting substrate, said electrical resistance heating material forming a predetermined circuit path having a pair of terminal end portions; and
(d) securing said first molded section to said second molded section, such that said first and second molded sections substantially encompass said circuit path and at least a portion of said heating element is secured in a gapped area defined between said first and second molded sections by a mechanical fit between said molded sections.

Abstract
A heated element assembly and method of manufacturing heated element assemblies is provided. The heated element assembly including a first and second molded sections shaped to mate with each other is provided. A resistance heating element is secured between the first and second molded sections by an interference fit. The resistance heating element includes a piercable supporting substrate and a resistance wire sewn thereon. The resistance wire is disposed in a predetermined circuit path which is substantially encompassed by the first and second molded sections. The resistance heating element is easily fixed in a position between the first and second molded sections and is capable of providing heat on vertical, horizontal and contoured surfaces.

14. A method of manufacturing a heated element assembly, comprising the steps of:
-
(a) providing a first molded polymeric section;
(b) providing a second molded polymeric section shaped to mate with said first molded section;
(c) providing a resistance heating element, comprising;
(i) a first heat resistant supporting substrate having a first surface thereon;
(ii) an electrical resistance heating material sewn with a thread to said first heat resistant supporting substrate, said electrical resistance heating material forming a predetermined circuit path having a pair of terminal end portions; and
