ABSTRACT:
A roll support for a web fed rotary printing press supports a supply roll of a material web between clamping cones carried at free ends of support arm pairs. An array of strain gauges are attached either to the support arms or to a force measuring bushing for the clamping cones and are used to provide values indicative of the weight or bearing force of the supply roll. These values can be used to determine the amount of material remaining on the supply roll or to determine a weight imbalance in the supply roll.
