Guidelines for Rolls Used in Web Handling AIMCAL

A Flex Spreader is a roller that has a spiral grooving cut into a soft rubber covering. The grooving starts at the centeris cut at an angle so that the web tension deflects the lands outwards, carrying the web with them to provide the spreading action. The amount of spreading is a function of rubber cover hardness and Web Tension.
