Abstract: A continuous composite web from which electrical low temperature heating mats can be produced by transverse cutting at certain positions and possibly by effecting an edge insulation and attaching electrical connections. A method for the production of such webs is also disclosed. The web consists of resistance foil material between two insulating foil layers which are joined in the areas of direct contact to secure the resistance foil. The resistance foil material is in the form of parallel, continuous, longitudinal strips and transverse strips extending transversely to said longitudinal strips at desired intervals and connected thereto to form electrical connections between adjacent foil strips. The transverse strips extend substantially across the total width of the web and can be in the form of an insulation strip having flat foil conductive pieces on the insulation strip.
