Abstract:
1. A method of producing a support belt for an elevator installation, comprising the steps: providing at least one tensile carrier formed as a cable; forming a free space as an area between an external surface of the at least one tensile carrier and a molding device and between opposing contact points of the at least one tensile carrier and rim edges of the molding device; embedding the at least one tensile carrier in a first belt layer formed of a first plasticizable material to form a part-belt with a first outer surface and a connecting plane surface wherein the at least one tensile carrier protrudes partly out of the connecting plane surface of the part-belt at the free space thereby forming a protruding portion, and the protruding portion of the at least one tensile carrier is covered at least partly by the first plasticizable material; and molding on the part-belt a second belt layer of a second plasticizable material at the connecting plane surface and the protruding portion of the at least one tensile carrier to form an elevator support belt with the first outer surface on the first belt layer and a second outer surface on the second belt layer.
