A back-up brake assembly for a partition feeder mechanism for preventing back-up movement of a partition strip fed therepast. The assembly comprises a partition guide having a guide surface for movement of a partition strip therealong from a receiving end to a forward end. A pivot arm is mounted for pivotal movement about a generally vertical axis and has an end adapted for engagement with a partition strip as it moves therepast. Means are provided for biasing the engaging end of the arm toward the guide surface for engagement with a partition strip as it moves past. The relative locations of the pivotal axis, and the engaging end of the arm are such that forward movement of the partition strip through the guide means into contact with the engaging end of the arm, moves the engaging end away from the guide surface causing pivotal movement of the arm against the bias, and further such that a back-up movement of the partition strip while engaged with the engaging end of the arm produces a moment about the pivotal axis tending to pivot the arm in the opposite direction and move the engaging end toward the guide surface, thereby wedging the partition strip between the engaging end and the guide surface. A recess is provided in the guide surface adjacent the engaging end of the arm such that a portion of the partition strip overlying the recess is urged into the recess by the engaging end under a force tending to urge the partition strip to back up.

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.
