Abstract: A ball bearing in a conveyor device for sheets includes ball guide bodies having ball guide openings formed therein. Balls are to be disposed in the openings. The ball guide bodies have lateral contact slits formed therein through which the balls can be removed and replaced through the ball guide openings by contact with the balls from the outside.

Abstract: Device for feeding and further processing printing material in sheet-fed rotary printing presses includes a paper storage having a roller pair for conveying sheets out of the paper storage and a feed table movable relative to the paper storage. An optical detection device for detecting mis-fed sheets is disposed in the paper storage behind the roller pair and forward of the feed table. A transport roller and an intermediate gear wheel for driving the transport roller are mounted in the feed table. A device is disposed in the feed table for removing mis-fed sheets, and includes a shaft, at least two remover rollers rotatably mounted on the shaft, and an upper guide plate and a lower guide plate disposed adjacent the remover rollers. The guide plates, respectively, are formed with recesses and define therebetween a travel path for the sheets. The remover rollers dip into the recesses, and are cooperatively associated with the transport roller for removing mis-fed sheets.

Abstract: A sealing device for a dampening unit on an offset printing press having a channel for receiving a dampening-solution supply and defined by a dampening-solution applicator roller and a metering roller which roll on one another, and having a seal holder mountable on a side part of the dampening unit and being in contact engagement with a sealing element, closing off one end of the channel, the sealing element having formed with an overflow opening for excess dampening solution, comprising a drain passage located between the sealing element and the seal holder and formed by a cutout on a side of the sealing element facing away from the channel, the cutout being connected with the overflow opening.

Abstract: A device conveys and aligns sheets on a feed table of a printing machine having a single-sheet feeder, an aligning section, and a conveying device revolving on shafts for conveying the sheets in a direction across the aligning section to feed rollers for feeding the sheets to an impression cylinder. Bearings are secured to side frames of the feed table so as to be cyclically adjustable in elevation. The shafts are rotatably mounted in the bearings and are cyclically displaceable laterally to the sheet-conveying direction. A guide device is secured in the side frames. A feed plate is carried by the guide device above the feed table and is laterally adjustable with respect to the position thereof on the guide device. The conveying device includes a revolving conveyor device disposed below the feed plate. The feed plate is formed with aligning edges disposed laterally forward of and behind the revolving conveyor device and constitutes a lateral aligning limit.

Abstract: A feed table unit of a sheet-fed printing machine with machine side frames for feeding sheets of paper from a stacker to a printing unit includes a feed table including a table top, two side parts holding the table top, a conveyor having a drive for revolving the conveyor about the table top, and deflection rollers supported in the side parts for guiding the conveyor, the feed table being supported so as to be laterally displaceable with respect to the machine side frames from an operating position to a rest position, the feed table being laterally lockable into the operating position thereof, the printing unit having a drive connected with the deflection rollers in the operating position of the feed table.

Abstract: A friction roller for the inking or moistening unit of a printing press, the roller axle of which is mounted on the side frames of the printing press, and the roller body of which is driven through frictional engagement by the inking or moistening unit roller, the roller body executing a to-and-fro movement on the roller axle in its rotation, in such a manner that the lateral stroke movement of the roller body can be controlled and executed with any desired frequency.

Abstract: A device for performing a circumferential-register adjustment in a sheet-fed rotary printing press with a printing unit including an impression cylinder, a blanket cylinder and at least one plate cylinder engageable with the blanket cylinder and drivable by the impression cylinder via an intermediate gearwheel, comprising a mounting movable with respect to the machine frame, the one plate cylinder being held in the mounting together with the intermediate gearwheel as well as with inking and dampening units assigned to the plate cylinder, the mounting being held in the machine frame so as to be swivellable about an axis disposed parallel to axes of the cylinders of the printing unit and lying at a point of intersection of a straight connecting line through the axes of the impression cylinder and the intermediate gearwheel.
