Hand-rail and fabrication method thereof

摘要

A hand rail with or without a wedge for moving staircases comprises a press moulded structure with a lower outer layer forming both a sliding layer and also partly a driving layer, an inner layer for longitudinal load bearing and an upper outer layer forming an elastic cover over the rail. The lower outer layer has two symmetrical longitudinal recesses in which the layer seams are formed, the recess spacing being greater than inner layer breadth. A claimed tool core for pressing the hand rail has two symmetrical longitudinal guide ribs on the upper face for forming the recesses and centering the inner load bearing layer. The core and/or the lower tool part have two or more additional longitudinal guide ribs in the rail lip region.
