Abstract: An apparatus for assembling and depositing signatures and for laying one upon the other of two different or differently oriented partial inner books made up from the signatures thus assembled.

Abstract: A sheet deliverer apparatus for a sheet processing machine, particularly a sheet printing machine with a high stapling or stacking sheet delivery capability, wherein sheet deliverer upper and lower chain guide ways extend in the same direction of curvature, and a clamping device is provided to clamp the sheet deliverer chains in tension to provide very even and silent running of the sheet deliverer chains and the gripping pads, extended service life and uniform sheet travel free of flutter over the complete conveying way to the delivery staple or table or permit increased conveying output.

Abstract: This invention concerns a film dampener unit for offset printing presses, with a dampening medium container in which a constant level of dampening medium is maintained, and with a dampener ductor of pan roller dipping into the dampening medium and transferring the dampening medium as a film onto at least one form roller which contacts the printing plate on the plate cylinder, whereby the thickness of the dampening medium film is determined by a metering roller which engages the dampener ductor roller surface in its rotary motion before the same engages the form roller. In order to reduce the number of rollers required for a flexibly operating dampener unit, the dampener ductor of this invention also functions as a dampener vibrator or oscillating ductor, having in addition to a rotation drive, another drive mehcanism which effects an axial back and forth or reciprocating movement.

Abstract: A process and apparatus for measuring the alcohol content of damping fluid for alcohol damping systems such as in offset printing presses for the purpose of keeping the alcohol concentration at a constant set value by injecting alcohol into the damping fluid in addition to the constant or parameter dependent addition of alcohol.

Abstract: An inker and form roller unit for a printing press includes a continuously rotating fountain roller for carrying ink from a reservoir. A combi-roller is in constant contact with a distribution roller to deliver ink to rollers of the printing press. The combi-roller and distribution roller are supported by a swivel lever that can pivot about the rotational axis of the distribution roller. The swivel lever carries a cam roller for contact with a control body having two or more sections, one of which is for continuous film inking and the other section for intermittent inking. The combi-roller is positioned relative to the fountain roller by the control body so as to form either a continuous fluid transfer gap or an intermittent fluid transfer gap.

Abstract: An apparatus for assembling and depositing book signatures by means of signature-receiving compartments which are movable independently of one another and independnetly of a common rotary hub on which the compartments are carried to provide improved signature receiving, stacking, aligning and discharge, among other benefits.

Abstract: The invention relates to a device for combining partial piles of book pages by laying one on another. The partial piles may be brought up alternately in an inclined position on a conveying chain. According to the invention, there is provided above the conveying chain a rotary rearranging apparatus. The rearranging apparatus carries a plurality of gripping systems each adapted to pick up one partial pile of book pages and, after rotation of the rearrangement apparatus through a 360 degree revoluion, deposits the partial pile of book pages beside an identical succeeding partial pile. During the 360 degree revolution of the rearranging apparatus, each gripping system is rotated about an axis parallel to the rotational axis of the rearranging apparatus such that the gripper systems continuously remain in an upright orientation with the grippers always projecting downwards at the lowest point of the gripping system.

Abstract: A method and apparatus for varying the flow of ink by differential adjustment at individual adjustment locations along the length of an ink metering device of a printing machine inking mechanism by a plurality of adjusting devices such as control motors, stepping mechanisms or the like, which are adjustable to differing extents by electronic control devices in accordance with variations in reference value presettings which are the same for all individually adjustable adjustment locations, using reference value-real value comparators which cause actuation of the adjusting devices, in which a reference value memory is provided for each adjusting device, and upon input of reference value variations the values of all reference value memories are multiplied by a selected predetermined reference value variation factor and the products of the multiplication are transmitted as new reference values to the reference value-real value comparator.

Abstract: This invention concerns a sheet gripper for sheet processing machines, especially for single- and multi-color printing presses of random printing processes as well as for numbering machines, coaters, folders, and similar apparatus. To permit interchange of one of several sheet grippers for another without removing the gripper spindle from the machine, the sheet gripper is formed with an open portion which encloses the gripper spindle through a maximum arc of 180.degree. and is fixedly retained in radially centered relation against the gripper spindle by a gripper lifter or carrier, also referred to as a drive dog, which is fixedly secured to the gripper spindle as by means of a screw or other removable fastener which extends through the drive dog or carrier and into the gripper spindle.

Abstract: A control and regulating apparatus for a sheet-delivery device for sheet-processing machines, and in particular, for sheet-printing machines, is provided.Several of the adjustable elements of the delivery device have separate control motors with feedback of the setting attained to a reference-value-setting meansor they have electromagnetic valves. The reference-value-setting means is provided with a respective input means for paper weight, sheet format and speed of rotation of the machine, and it is connected to or integrated with a computer which supplies to the reference-value-setting means the reference values in respect of all settings of the feeder, such reference values being empirically determined for each operating condition and stored in the form of a family or characteristics.

Abstract: An inking train for a printing press wherein an ink splitting cylinder acquires from an ink transporting roller preferably an approximate 50% portion of the ink load carried thereby whereby an approximate 50% portion of the ink load remains on the ink transporting roller; a pair of countercycling ductor rollers lift ink alternately from the ink transporting roller and the ink splitting cylinder and deposit the ink so lifted upon subsequent roller means in the inking train for subsequent recombining of the ink load portions upon a common roller for further transport thereof through the inking train.

Abstract: Apparatus for adjusting the position of an ink blade at individual locations along its length, or the position of individual ink metering elements, relative to an ink ductor in a printing machine inking mechanism by rotatable set screws, having a position locking transmission between each set screw and the free end of the ink blade in the respective location or of the associated ink metering elements, for positively increasing or reducing the feed gap of the ink blade or ink metering elements which at its underside is fixedly connected to transversely extending pivot pins, in which each set screw is associated with a respective joint, having a pivot axis which extends transversely with respect to the set screw center line and parallel to the plane of the ink blade or ink metering elements, secured to one end of the associated set screw, which end, in use, projects out of an ink fountain into which the set screw is adjustably screwable and mountable, one end of a respective adjusting lever which is disposed ap

Abstract: A paper folding and conveying apparatus and method and more particularly an improved apparatus and method for the high speed conveying of paper strip and imparting an overlying fold thereto.
