Abstract

The equipment detects cracks and breaks and also the end of a strip of any material while moving. It has a feeler mounted near the strip and actuated by a button etc, following alterations in the direction of the strip material and/or oscillations during forward movement. It acts with a shock load in the opposite direction, variable to suit the mechanical strength, penetrating into cracks, and initiates operation of a control automatically performing the necessary operations while the strip is travelling at full speed.
