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.
Claims27
Handrail for use with escalators, travelators and similar, which has a C-shaped cross-section with a centre section and lip regions, a sliding layer and a rubber covering layer for the user as external layers, a tension carrier layer oriented in a longitudinal direction, and at least one strengthening layer on each side of the tension carrier layer and running into the lip regions, characterised in that
- at least one of the strengthening layers is a rubber layer having uniformly distributed short fibres which exhibit a preferential orientation and run at an angle other than 0° to the longitudinal direction of the handrail.
