Abstract

An unwinding apparatus for rolls of materials pivotably mounts the rolls with a pivot drive at each end of the roll. The torque of each pivot drive is equalized relative to the machine frame in each direction of rotation by providing for each pivot drive, a resiliently mounted lever which is fixed to the pivot drive and a contact member which is linked to the lever. Four switches are arranged in pairs symmetrically with respect to the contact member and are actuated thereby in response to movement of the lever resulting from torquing by the pivot drives.
