Abstract
A method of manufacturing a reinforced strip of insulative material comprising the steps of extruding a thermoplastic insulative material in the shape of a tube or spaced apart strips about a plurality of separated and substantially parallel reinforcing strands positioned within said tube or strips and compressing and cooling the tube or strips to form a flattened single strip having opposed flattened sides with the reinforcing strands firmly secured therebetween is disclosed. A reinforced support for a ballast resistor manufactured in accordance with the described method is also disclosed.
Claims3
A ballast resistor for a gas discharge lamp unit comprising a resistive wire helically wound around a reinforced insulative strip to exhibit a relatively uniform resistance over the length of said wound resistive wire, said reinforced insulative strip comprising a plurality of separated and substantially parallel reinforcing strands embedded between substantially flat strips of insulative thermoplastic material which are extruded and thereafter compressed together sufficiently to form a bond therebetween.
