Abstract: Apparatus for affecting positional adjustment of a machine member has an adjustment screw nonrotatably connected to the machine member and screwed into a nut formed as a worm wheel. The worm wheel, meshes with a worm, connected by a worm shaft to an actuator assembly for rotating the worm. The worm shaft is rotatably and axially displaceably mounted in a housing in which the worm wheel is rotatably mounted and the worm shaft is rotatably and axially non-displaceably mounted in a slider, which is guided in the housing for movement in the axial direction of the worm shaft. The slider is reciprocable by a fluid-operable piston-cylinder unit to an extent which corresponds to the desired adjustment of the screw.

Abstract: A device for engaging form rollers in an inking unit of a printing machine with a plate cylinder of the printing machine and for disengaging the form rollers therefrom, including bearing levers for the form rollers disposed at both side frames of the printing machine, the form rollers being pivotable on bearings of mutually adjacent distributor rollers and being engageable with and disengageable from the plate cylinder by an adjustment element includes at each side frame, a pair of control levers to each of which the two bearing levers, respectively, are articulatingly connected via respective straps, both of the control levers being pivotally mounted on respective stud bolts at the side frames of the machine; a compensating web, respectively, coupling the pair of control levers at each of the side frames; and a respective control cylinder engaging the compensating web and supported on one of the side frames.

Abstract: An ink transfer arrangement for and a method of transferring ink to an engraved die surface of a reciprocatable die in a printing press of the type including a die drive for reciprocating the die, and a press ram drive for pressing sheet material to be printed against the ink engraved die surface to produce intaglio printing are disclosed. A rotatable inking roller is normally mounted on an ink fountain in inking engagement with a fountain roller also mounted on the fountain. Ink from the fountain is transferred to the fountain roller, and thereupon to the inking roller. The inking roller is mounted for limited displacement relative to the fountain roller in a direction transverse to the axis of rotation of the inking roller.

Abstract: The disclosure relates to a cartridge type supply device for use with a portable, one-hand-operable labeling machine of the type including a printing mechanism with printing types arranged for imprinting inscriptions on each of a series of labels traveling along a predetermined path through the machine toward a dispensing opening of the machine. The ink supply device comprises a cartridge holder pivotally supported at one end thereof within the labeling machine in a readily detachable manner and a replaceable inking roller cartridge supported detachably by the other end of said cartridge holder said cartridge including a rotatable inking roller. The cartridge holder is spring-biased to urge the inking roller onto surfaces of the printing types of the printing mechanism of the labeling machine. When the inking roller cartridge is used up, the cartridge holder can be taken out of the machine together with the used cartridge. A cartridge box for housing spare inking roller cartridges is provided.
