Abstract: This bearer wiper assembly (10, 12) includes independent extensible arms in the form of pneumatic rams (28) provided for each printing press bearer (14, 16). The pneumatic rams (28) are pivotally mounted to a support bracket (22) in swing-away relation and a bearer wiper unit (70) is provided at the remote end of each ram. The rams are releasably held in place by a latching mechanism (48, 60) and each wiper unit (70) includes by an ell-shaped pad (72) releasably clamped to a mounting frame (76) carried by each ram (28). The bearer-engageable portion (98) of each pad (72) is apertured to collect foreign particulate matter from the bearers (14, 16).

Abstract: A wiper assembly (1) for a printing apparatus comprises a finger bar (19) extending longitudinally of printing rolls (5, 7) in a spaced relation thereto at the point of contact between the rolls. Pneumatic rams (33, 35) are attached to respective ends of the finger bar adjacent the bearer members (9, 11, 13, 15) on the rolls. Wiper pads (53, 55) are attached to the ends of each ram and engage the roll bearers. A compressed air supply (81) activates the rams to move the wiper pads into and out of contact with the bearers.
