ABSTRACT:
An uncoiler for metallic strip material may suffer from rotational effects of a coil supported on the mandrel if the coil is eccentrically mounted on the mandrel. The uncoiler has means for detecting these rotational effects and, if the effects are greater than a predetermined level, a signal is prepared which is used either to prevent further increase in rotational speed of the mandrel or to reduce the speed of the mandrel.
