ABSTRACT:
A method of manufacturing a support structure for an electric heating assembly from a single piece of metal. The piece of metal is advanced progressively through a plurality of work stations. At a first station, excess material is removed from the piece of metal to provide a strip of metal extending transversely between second and third strips of metal. At a next station, the transversely extending strip is formed into a channel-like member. Thereafter, insulators to mount the heating element are loaded onto the channel-like member. The second and third strips of metal are bent at right angles to the first strip to provide integral side supports for the support structure of the assembly.
