ABSTRACT:
An idler roll brake in a paper handing machine wherein the roll brake employs a brake shoe mounted to the roll end bearing. The brake shoe slides forward to bring the brake shoe against the interior surface of the roll. An electromagnet positioned external to and mounted closely spaced from the cylindrical shell the roll attracts a ferromagnetic armature or permanent magnet mounted to the brake to pull the brake shoe into engagement with the inner surface of the roll.
