Fast Action Clamping System

The Fast Action Clamping System is fitted with a clamping ring which is increasingly offset to the shaft with which is engages in response to axial or tensioning forces, so creating an increasing friction contact. The greater the tensioning force, the greater is the clamping effect of the rings.
As the roll or spool is held firmly between the fixed cone and the clamping cone, braking moments are able to be transmitted from the shaft to the roll or spool. The machine can thus be quickly stopped if a fault occurs.
