Abstract

A passenger conveyor handrail (30) includes a plurality of teeth (36) that interact with a toothed driving member (42). In a disclosed example, a low friction material (60) is placed near an end of the teeth (36) on the handrail (30). The low friction material (60) facilitates the teeth sliding along a guidance (70) but does not interfere with a desired engagement between the teeth(36) and corresponding teeth (46) on the driving member (42).
