ABSTRACT:
A brake mechanism for an accumulation conveyor includes a brake frame supporting a brake pad at an angle and movable between a lower braking position with the brake pad frictionally engaging one of the conveyor rollers on an upper non-braking position. Preferably, the brake frame includes pressure rollers for moving a roller driving belt into contact with the conveyor rollers in the non-braking position and out of contact with the rollers in the braking position. The brake frame includes ramp members engaging bearing rollers on the conveyor frame, and an extendible member is operable by actuation of a downstream signal roller to move the brake frame relative to the conveyor frame.
