ABSTRACT:
A roll breaker (20) in the form of a lever (130) of the first class with a fulcrum (54) adjustable in height. A striker assembly 70 is positioned near one end (136) of the lever, and the other end (131) is inserted in the roll to be broken. When the striker is wound and triggered, by a motor (112), it impacts downward on the lever end 136. A bumper (30) is provided to determine the depth of insertion of the lever end (131) into the roll, and an arrangement (137, 140) is also provided to prevent the second end of the lever from rising above a predetermined level.
