Abstract
A brake, particularly adapted to stop feeder rolls of a paperboard partition assembly machine quickly, of the drum and embracing arms type, the two brake arms spring-urged into contact with the drum, with cam-operated means for separating brake shoes from the drum; there being cooling means for the brake including integral air-cooling ribs projecting from the brake arms, and air pressure means having two circumferentially and axially spaced outlets on each brake arm to direct air through the brake arm and the brake lining to the outer surface of the drum both to cool the outer parts of the drum and to clean the outer surface, the outlets being automatically cut off when the brake is in braking position, and there are air-circulating fins on the brake drum that draw air across the inner parts of the drum.
