Abstract: A device for registering a sheet with a side stop at either one of the opposite lateral edges of a feed table in a printing press. The device includes a housing having a top surface which is flush with the feed table. A suction head is flushly recessed in the surface of the housing and mounted in a slide in the housing for limited reciprocating movement. The housing is shiftable between alternative working positions at the respective lateral edges of the feed table. For driving the suction head timed with the arrival of a sheet, a drive shaft is provided in the housing having a pair of face type cams spaced axially from one another cooperating with a cam follower which is secured to the suction head in a position between the cams. Springs are provided for biasing the suction head in opposite directions. A shiftable yoke selectively engages the springs with the suction head so that the cam follower engages a selected one of the cams.

Abstract: An ink metering arrangement for a printing press including a fountain roller having a plurality of slides arranged edge-to-edge in respective column positions, each slide being adjustable so that its tip forms a gap with the roller thereby determining the rate of ink flow in the corresponding column position. Each slide has a reversible motor for driving the slide over a limited range of movement with respect to a slide reference position. A potentiometer is connected to the motor for producing an electrical output signal corresponding to the degree of slide displacement, the potentiometer having a stop to establish a reference output condition. A slip clutch is interposed in at least one of the motor connections so that when the motor is energized in a first direction the potentiometer and slide are both driven to their reference positions accompanied by relative slipping movement of the clutch notwithstanding the fact that the tip of the slide may have been shortened by wear against the roller.
