Abstract
The invention relates to a hand-rail that can be used for escalators, moving pavements. The inventive hand-rail has a C-shaped cross-section, outer layers in the form of a sliding layer and a rubber top layer for the user, a layer with tractive support elements, especially steel chords that are embedded in rubber and oriented in a longitudinal direction, and at least one respective reinforcing layer extending into the lip areas on both sides of the tractive support elements. At least one of the reinforcing layers consists of a rubber layer with homogeneously distributed short fibers with a preferred orientation, extending at an angle deviating from 0° in relation to the longitudinal direction of the hand-rail.
