ABSTRACT:
A brake assembly for stopping moving sheet stacks on a folding table of a rotary printing press and a method of operating the brake assembly is disclosed. A rotatable drum carries a plurality of axially extending stop rods spaced about the periphery of the drum. Each of these stop rods is carried on bearing arms that are spring biased. Each moving sheet stack contacts a stop rod which absorbs the energy of the moving sheet stack and causes it to stop on the folding table. The drum rotates in an intermittent fashion to bring a different stop bar into engagement with each succeeding sheet stack. A gear drive assembly for the brake assembly is also disclosed.
