Winder rider roll control

Abstract From the Canadian patent

A winder rider roll assembly for paper rolling devices is provided with a rider roll having a counter weighting system in which chains affixed adjacent axial ends of the rider roll assembly are entrained over chain sprockets nonrotatably affixed to a cross shaft mechanism with one sprocket for each chain being affixed to one piece of a two piece cross shaft with the cross shaft pieces being torsionally connected through a variable spring rate coupling employing selectively inflatable air bags for transmission of torsional forces. Also disclosed is a method of controlling the level and force of the rider roll by varying air pressure in the air bags of the variable spring rate coupling.
