ABSTRACT:
A wheel for driving a flexible handrail of an escalator or moving walk. The wheel can be turned about an axis of rotation and has a readily elastically deformable layer. The readily elastically deformable layer is formed by a body that is stable in form when free of stress. Arranged adjacent to an inner circumferential surface of the readily elastically deformable layer is an inner layer that is stiffer than the readily elastically deformable layer. Adjacent to an outer circumferential surface of the readily elastically deformable layer is an outer layer that is intended to rest against the handrail under static friction. Respective adjacent layers are coupled to each other in non-rotating manner.
