Abstract
A process for producing a support belt for an elevator system includes steps of: placing at least one cable-shaped tension support in position; embedding the tension support in a first belt layer made from a first plasticizable material to produce a partial belt having a first outer surface and a surface which forms a connecting plane, wherein parts of the tension support project out of the connecting plane and at least parts of the projecting portion of the tension support are covered by the first plasticizable material; and integrally forming a second belt layer made from a second plasticizable material on the connecting surface of the partial belt and the projecting portions of the tension support so as to produce a support belt having the first outer surface on the side of the first belt layer and a second outer surface on the side of the second belt layer.
