Abstract

A process of producing a pliable roller uses a flexible strip of material with a tension element longitudinally therealong, the tension element having a lesser longitudinal extensibility than the flexible strip of material. The tension element and the flexible strip of material are fixed together and portions of the flexible strip of material are longitudinally folded together along the tension element. At least after the fixing, the flexible strip of material with the tension element longitudinally therealong is wound, longitudinally, about a roller core in such manner as to form contiguous windings thereabout projecting outwardly from the roller core.
