DEFINITION

Classification: 338/264

(under subclass 263) Subject matter wherein the resistance element is wound or coiled on a core, the surface of the core engaging the helix or winding over substantially the entire periphery of the core and over the entire axial length of the helix or winding as for example to reinforce or shape the helix or winding over its length.

(1) Note. The manner of assembly of the element on the core is immaterial for classification in this subclass. Often the coating acts as an adhesive to secure the resistance element to the core.
