    Abstract: A handrail with or without a wedge for escalators and speedwalks involves a number of permanently connected molded layers wherein the lower outer layer of the handrail, in part, constitutes a slide layer and, in part, constitutes a conveyor layer, an inner layer having increased longitudinal strength constitutes a traction carrier, and the upper outer layer constitutes an uppermost elastic coating of said handrail, wherein said lower outer layer has at least two symmetrically arranged longitudinal grooves whose spacing is somewhat larger than the width of said inner layer having increased longitudinal strength. The tractor carrier of the handrail is always accurately centered so that it does not tend to lateral movement.
