Curved tube section web spreading roller - has powered universal shaft connected to carrier sleeve at the axis end

摘要

The roller to spread out webs of paper, fabric or plastics, using a number of closely spaced, rotating tube sections on a rigid curved axis, has a universal shaft (2) powered by an electro-motor (8) as an extension of the roller axis (1). The torque is transmitted through a carrier sleeve (3) at the end of the axis (1), on which the tube sections (4,4') are centred. ADVANTAGE - The assemble gives a constant drive speed, without the need for a drive disc with V-belts or toothed belts or countershaft.
