PROCESS FOR MAKING A FLAT HEATING ELEMENT, IN PARTICULAR FOR CAR SEAT HEATERS, AND FLAT HEATING ELEMENT MADE BY SAID PROCESS

摘要

To facilitate handling of support material in the manufacture of flat electrical heating elements and to improve the gas permeability of bonded layers from which such heating elements are made, the heating conductor (18) is secured to a support (6) at isolated points or only in a line along the heating conductor (18) so as to temporarily fix the heating conductor (18) before at least one further covering layer (30) is laminated over it. To this end, the heating conductor (18) is briefly heated by connecting it to an electric current source, and then bonded to the softening adjacent layer (6).
