Patent number: 5379694Abstract: A lateral register system, in particular for flexible printing forms which are held by their edges in an axially extending gap in a plate cylinder, the edges being pre-bent according to the inclination of the gaps. The register system includes an insert strip for each printing form, which insert strip can be inserted into the gap and has at least one stationary register pin. When a plurality of printing forms are to be held in a common gap, the insert strips have different lengths and can be placed one on top of the other so that each printing form can cooperate with the register pin provided for it. Each insert strip can be adjusted individually in the axial direction of the plate cylinder by an adjusting system.Type: GrantFiled: December 8, 1993Date of Patent: January 10, 1995Assignee: MAN Roland Druchmaschinen AGInventors: Josef Hajek, Anton Neumeir

Patent number: 5341735Abstract: To facilitate expansion of modular printing units (1, 2, 3) and particularly vertical expansion into tower printing stations (1-4; 2-5; 3-6), each printing unit, with its own printing cylinder (20)and drive motor (8-13), has associated therewith a power take-off unit (14-19; 53-56) which, via a right-angle drive, synchronizes a horizontal synchronizing shaft (21) with individual vertical synchronizing shafts (22, 23, 24) of two-tier or two-level or tower printing stations.Type: GrantFiled: August 17, 1993Date of Patent: August 30, 1994Assignee: MAN Roland Druckmaschinen AGInventor: Josef Hajek

Patent number: 5121910Abstract: To permit web portions (16, 17; 18, 19; 20, 21) slit from longitudinal webs (2a, 2b, 2c) to be selectively interleaved or interlaced, with or without turning over, pairs of turning bars or rods (6, 7; 8, 9; 10, 11; 12, 13) are located in essentially vertically aligned position; laterally of the turning rods, two deflection rollers (22, 23) are positioned which can be individually movably shifted by individual drive motors (32) operating a gear on a rack formed on guide rails, so that the deflection rollers can be selectively positioned at the level of a selected pair of turning rods. This permits placement of a web portion, right side up or turned over, between a pair of web portions which is not necessarily the next adjacent one in the vertical sequence of superimposed webs arriving at the interlacing or interleaving system.Type: GrantFiled: January 23, 1991Date of Patent: June 16, 1992Assignee: MAN Roland Druckmaschinen AGInventors: Josef Hajek, Norbert Grimm

Patent number: 5100117Abstract: To selectively place web portions slit from a printed paper web with a left web portion above a right one over a right web portion above the left one, the parallel-arriving web portions are so guided through a turning bar looping of the right or left web about the turning bars, with superposition, which involves a 90.degree. position change of the turning bars, and while maintaining the air cushion between the paper web and the turning bars, the level of the arriving web with respect to the first-encountered or passed over or looped about turning bar is controlled or so set that the web will engage the turning bar tangentially with the plane of the arriving web portion and delivery web portion parallel to each other, by, respectively, guiding the web portion either above the turning bar pair or from below the turning bar pair, upon 90.degree. shift of the turning bar pair.Type: GrantFiled: April 3, 1991Date of Patent: March 31, 1992Assignee: MAN Roland Druckmaschinen AGInventors: Josef Hajek, Norbert Grimm

Patent number: 4821640Abstract: To permit both circumferential as well as axial register adjustment of three printing couples (1, 2, 3), in which the respective cylinders of the printing couples are interconnected by spiral gears, two of the blanket cylinders (4, 8) are axially shiftable. The changes in circumferential register, upon changing of lateral register--due to the spiral gears--are compensated by position motor controllers (34, 44) which may include a microprocessor (50), automatically. Lateral register is set in a predetermined sequence by the respective cylinders, in accordance with the coupling of one of the plate cylinders (e.g. 5) with a printing machine main drive pinion (68).Type: GrantFiled: April 13, 1988Date of Patent: April 18, 1989Assignee: M.A.N. Roland Druckmaschinen AGInventors: Josef Hajek, Hans Mamberer

Patent number: 4429630Abstract: To provide a compact drive arrangement for a plurality of axially oscillating or reciprocating milling rollers (11, 12, 13) used in inkers and/or dampers of rotary printing machines, a central gear (16) is provided, driven from the plate cylinder (5) of the printing system, and wide enough to permit axial excursion of meshing gears (11', 12', 13') coupled to the respective milling rollers, and engaged with the central gear.Type: GrantFiled: January 24, 1983Date of Patent: February 7, 1984Assignee: M.A.N.-ROLAND Druckmaschinen AktiengesellschaftInventor: Josef Hajek

Patent number: 4406224Abstract: To permit easy cleaning of an ink trough, for example upon change of color or type of ink for an offset printing machine, the ink trough is formed with a cross rail to which the doctor blade engaging the ink duct roller from below is attached. The structure includes a pivotable holding rail positioned below and beneath the doctor blade, and means to hold the holding rail in position against the cross rail, the ink zone adjustment screws passing through and being retained by the holding rail. Upon loosening of the attachment means, the holding rail and with it the adjustment screws and possibly an override cross strip and its adjustment screws are pivoted away from the doctor blade, which will become unstressed, thus leaving a gap between the end of the doctor blade and the duct roller, preferably not less than 1 cm wide, to permit ink to drain out of the trough, for example into a receiving vessel.Type: GrantFiled: June 2, 1981Date of Patent: September 27, 1983Assignee: M.A.N.-Roland Druckmaschinen AktiengesellschaftInventor: Josef Hajek

Patent number: 4321051Abstract: To provide a smoothly conically converging edge portion of a former, with air communication openings therethrough, the former sheet is bent over at the edge in the conically converging shape with the inner bent-over portion left free; core elements of conical shape matching the cone shape of the bent-over portion are introduced into the open space, and a curable resin such as epoxy, polyurethane or silicone is poured over the core, to adhere to the bent-over portion and the major wall portion of the former and, after dissolving of the core element, leaving air chambers to which air with differential atmospheric pressure can be introduced through connecting stubs which can be cast into the closing-off wall. Solvent, such as tetrachlorethylene to dissolve a polystyrene core can likewise be introduced through these stubs. If a plurality of core units are used, a plurality of separate air communication chambers can be formed with separating walls cast in the gaps or spaces between core elements.Type: GrantFiled: April 30, 1980Date of Patent: March 23, 1982Assignee: M.A.N.-Roland Druckmaschinen AktiengesellschaftInventors: Josef Hajek, Siegfried Rotter, Hans Schwopfinger, Josef Schwarz
