SUPPORTS FOR ELECTRIC HEATING ELEMENTS

摘要

Supports for electric heating elements A support for an electric heating element comprises a former of generally cylindrical shape, made of a heat resisting material and having a longitudinal core from which extend spaced ribs that support an outer wall. Portions of the outer wall and of the ribs are omitted along a helical path around the core to provide a mount for an electric heating element. A heating element assembly including the support and the heating element is mounted in a hot air gun. The support is made in two stages, the first stage being an extrusion stage and the second stage involving the machining of a helical slot in the extruded component.
