Abstract
A stop brake for a supply roll mandrel includes at least one brake arm pivotally connected to a support and capable of being pivoted out of braking engagement with the mandrel in response to advancement of sheet material from a supply roll against the return bias of a spring element. The brake arm cooperates with sheet material which is caused to follow a path around a dancer bar secured to the lower end of the brake arm causing the disengagement of the brake. The brake is caused to cooperate with the outer surface of a mandrel upon which a supply roll is mounted through a intermediary of a strap which holds the mandrel surface against rotation when advancement of sheet material is stopped.
