Abstract

PURPOSE: To get effectively a surface heater solid with a heating element and conductive wire, by putting the heating element between two layers of fused thermoplastic resin and cooling under pressure.
CONSTITUTION: This surface heater is composed of a heating element H made of cold-punched and corrugated metal foil and of insulation coating material Sh. The flexible heating element Hl is reeled out between slits d1 - d1' of a die D1, and fused thermoplastic resin is fed from an extruder E1 in the die to put the element H1 between the two filmy resin extruded through the slits d1, d1', The resin layers pass through pressure rolls R1, R1' and then are cooled and taken up. This heating element is reeled out to an extent required, and the coating is peeled off at both ends to fit a conductive wire L and terminal seal ST
