Abstract
A roll brake to prevent relative movement between a pair of rolls, one or both of which may be driven, in a coil wrapping machine or the like is described. A metal brake plank is placed under each end of each roll in a respective pair of parallel rolls and an air bag actuator is placed intermediate each end of each plank and the roll frame. For rotation of the rolls during wrapping the air bags are deflated but when a new coil is loaded onto the rolls the airbags are inflated thus driving the planks into locking relationship with the rotatable rolls and thus preventing any relative rotational movement therebetween.
