Abstract
A printing press assembly (10) with a powered paper roll loader (22) having a triangular frame made of a pair of spaced upright triangular frame sections (28) supporting a pair of load chains (36A, 36B) to raise and lower a pair of load hooks (32) and associated eject hooks (34) that support opposite ends of a core axle (16) of a paper roll (18). The load chains are powered by an electric motor (54) and gear box (48) driving a pair of sprocket pulleys (38A, 38B) interconnected by a tie shaft (33) to insure movement in unison. The control from the motor (54) has a pair of 'dead man' switches for optimal safety during operation, while the frame (28) is located beneath paper feed rollers (14) to reduce floor space utilization. The eject hook (34) is used to move the paper roll (18) from the operative position to underlying support by the load hook (32) to lower the paper roll (18) to the ground (17).
