    A printing unit for a rotary offset printing machine comprises a central impression cylinder (69) and four printing mechanisms mounted in bores in side wall members and each comprising a respective plate cylinder (65 to 68) and a respective blanket cylinder (61 to 64), the blanket cylinders (61 to 64) being journalled in eccentric bushes (74 to 77). The blanket cylinders (61 to 64) are selectably settable against the relatively small impression cylinder (69) for satellite printing; or they can be settable against each other in pairs to allow for either horizontal or vertical web paths, the impression cylinder being withdrawn axially out of contact with the blanket cylinder. Alternatively, the apparatus allows different printing mechanisms for horizontal and vertical web paths to be selectively mounted since the bores in the side wall member will accommodate either. <IMAGE>

    D- (V2- 1) d D (1) +12 mm. 4. Printed sections according to claim 1, characterized in that their side walls are divided respectively between upper and lower printing mechanisms.
    The invention relates to printing sections of offset role-playing rotary machines with four printing mechanisms for printing from rubber forms and satellite printing.
    In the magazine German printer (No. 19-20, 1977, pp. 200-206) there are offset printing units of the named type. The printing units have four printing mechanisms, each of which consists of plate and transfer cylinders, which are located around the satellite cylinder. In satellite printing, four transfer cylinders are in contact with the satellite cylinder. To translate into printing from rubber forms, there are printing sections in which the transfer cylinders arranged adjacent to each other when separated from the satellite cylinder are arranged to be installed in pairs against each other. With their help, it is possible to print from rubber forms with vertical movement of the paper web. In other printing sections, the transposition of the transfer cylinders arranged one above the other enables printing from rubber molds in the horizontal movement of the paper webs. For the purpose of adjustment, the transfer cylinders, as usual in eccentric bushings, are placed in the side stacks.
    . These sections have a common drawback due to the TPM / that when printing from rubber forms, they are applicable only to a certain movement of the paper webs. The rearrangement of printing sections from horizontal to vertical movement of the paper web or vice versa at a printing company is impossible. Even with the restructuring, for example with the use of other bearing sleeves for the transfer and plate cylinders, it is not possible to build in the printing mechanisms for other movements of the paper webs in the side walls of the printing sections. For each
    the movement of the paper web during printing from rubber molds, it is necessary to specially manufacture lateral
    walls, which requires increased application costs.
    The purpose of the invention is to establish a rational production of printed sections and expand their functionality.
    The object of the invention is that in the printing sections of offset role-playing rotary machines, which are equipped with a satellite cylinder and four printing mechanisms, each of which consists of plate and transfer cylinders. The transfer cylinders are located in eccentric sleeves and are interoperable
    With the satellite cylinder, while maintaining the same wall shape, ensure printing from rubber forms with vertical and horizontal movements of the paper web, as well as
    satellite printing.
    The problem is solved as follows.
    The transfer cylinders which are additionally mounted one on top of one another or another are arranged by means of eccentric bushings against each other, and the apertures in the wall always occupy the same position relative to one another, or the transfer cylinders arranged side by side and on top of each other selectively in pairs with each other. .
    In addition to the TorOj, the satellite cylinder is smaller than the transfer cylinder, nor
    In no case is it in contact with the interacting transfer cylinders and is axially withdrawn from the machine bed of the printing units.
    5 As a result, in the manufacture of
    Printing presses can be mounted with the same side walls of the printing units, both for printing from rubber forms with vertical and horizontal movements of the paper web, and for printing on a satellite principle. Walls can be made less diverse and more economical in quantitative terms. By placing the transfer cylinders against each other, the printing section on the printing company can be converted from satellite to printing from rubber forms with vertical or horizontal movements of paper sheets.
    All printing units according to the invention, depending on the position of the cylinders relative to the printing sections from rubber forms during horizontal, paper and satellite printing, have a smaller construction height than the known printing sections for printing from rubber forms with vertical movement of the paper web and satellite printing. Due to the lower height, access to the inking and moistening mechanism, the printing and transfer cylinders of the upper printing mechanisms is facilitated.
    The dock outlet from the machine bed of the printing sections of the satellite cylinder provides the convenience of withdrawing transfer cylinders from the zone. As a result of this, when shifting to printing from rubber molds, it is possible to avoid engagement of the teeth, which need to be separated, between the satellite and transfer cylinders. The paper web without contact with the satellite cylinder enters from the first to the second working transfer cylinder of the printing unit. This prevents print lubrication and ensures quality printing on coated paper.
    In addition, cleaning of the satellite cylinder is facilitated.
    The unification of the side walls of the printing units is achieved by the same position of the holes in the wall relative to each other.
    Low eccentricity of eccentric bushings advantageous for design and production can be obtained with the following ratio of the diameters of the satellite and transfer cylinders:
    D (-VT- 1) d D (-f2- 1) + 12 mm.,
    Choosing eccentricity by swapping the transfer cylinders to go from one print to another, reduces the distance between adjacent transfer cylinders mounted on the printing cylinder. At the lower value of the formula, this distance is O.
    The manufacture of printed sections is rational if the side walls are divided respectively between the upper and lower printing mechanisms.

    Shown in FIG. 1 the printing section contains four transfer cylinders 1-4, working with forme cylinders 5-8. The transfer cylinders 1-4 are located around the satellite5 of the casting cylinder 9. The trunnions of 10-13 cylinders are located in one of the eccentric sleeves 14-17 with eccentricity 18, and the trunnions 19-22 of the forme cylinders - in the corresponding
    0 eccentric bushing 23-26 with eccentricity 27.
    At the position 28 of the eccentric sleeves 14-17, the transfer cylinders 1-4 are attached to the satellite cylinder 5 and the printing section operates according to the planetary principle. At the position 30 of the eccentric sleeves 14-17 (Fig. 2), the adjacent transfer cylinders 1-4, when separated from the satellite cylinder 9, are mounted opposite each other and occupy the position indicated by the strokes. This provides the possibility of printing from rubber forms with vertical movement of the paper web. By displacing the satellite cylinder 9 through the sidewall opening of the printing unit (not shown), the possible printing of the satellite cylinder 9 on the way from the first to the second jointly operating transfer cylinders is prevented. Setting the forme cylinders 5-8 to transfer cylinders 1-4 in the respective positions
    5, when printed, is produced by eccentric sleeves 23-26. The eccentric bushings 14-17 are disconnected in position 29. The eccentric sleeve 17 (Fig. 2)
    0 is located symmetrically to the sleeve 16, and the eccentric sleeves 14 and 15 are symmetrical to the eccentric sleeves 16 and 17. When installing the transfer cylinder rv 1-4, the eccentric sleeves 14-17 can be inserted
    five
    in the following eccentric bushings.
    The printing section (FIG. 3) contains four transfer cylinders 31-34, each of which operates respectively with one of the forme cylinders 35-38. The transfer cylinders 31-34 are placed around the satellite cylinder 39. The pins 40-43 of the cylinders are located in one of the eccentric sleeves 44-47 with eccentricity 48,. The eccentric sleeves 44-47 and 53-56 are equally spaced relative to each other, as are the corresponding holes in the printing unit according to FIG. one.
    At position 58 of the eccentric sleeves 44-47, the transfer cylinders 31-34 are attached to the satellite cylinder 39 and the printing section operates according to the planetary principle. In order to transfer the eccentric sleeves 44-47 to the position 60 (Fig. 4), the transmission cylinders 31-33 arranged in a row are installed in separation from the satellite cylinder 39 against each other and occupy the position indicated by the strokes. In this way, it is possible to print from rubber molds. In the horizontal movement of the paper web. The satellite cylinder 39 is discharged through an opening in the side wall of the printing reaction (not shown). ,
    The adjustment of the forme cylinders 35 to the transfer cylinders 31-34 in respective positions is carried out by means of eccentric sleeves 53-56. To shut off, the eccentric sleeves 44-47 are shifted to position 59. The eccentric sleeve 47 (Fig. 4) is located symmetrically to the sleeve 46, and the eccentric sleeves 44 and 45, symmetrically to the eccentric sleeves 46 and 47. To improve the setting of the transfer cylinders 31-34, the eccentric sleeves sleeves 44-47 can be placed in subsequent eccentric sleeves.
    Due to the constant position in the walls of the cylinder bores, the printing units (FIGS. 1 or 3) can be mounted using the same side walls.
    The printed section depicted in FIG. 5, contains four transfer cylinders 61-64, working with one of the forme cylinders 65-68, respectively. The transfer cylinders 61-64 are located around the satellite cylinder 69, and their pins 7073 are located in eccentric sleeves 74-77 with eccentricity 78. Axles 79-82 form JX cylinders are placed in eccentric sleeves 83-86, respectively, with eccentricity 87 (the preferred separation of the side walls is indicated by a line from dashes and dots
    At position 90 of the eccentric sleeves 74-77, the transfer cylinders 61-64 are attached to the satellite cylinder 69 and the printing section operates according to the satellite principle. By moving the eccentric bushings 74-77 to the position 88 (Fig. 6), the adjacent transfer cylinders 61-64, when separated from the satellite cylinder 69, are positioned opposite each other and occupy the position indicated by the strokes. In this way, it is possible to print from rubber molds in the vertical movement of the paper web. If the eccentric sleeves 74-77 are rotated to position 91, the transfer cylinders 61-64 arranged one above the other are separated from the satellite cylinder and are set against each other. They occupy the position indicated by strokes and dots, at which printing from rubber forms is possible with the horizontal movement of paper canvases. For printing from rubber molds, Satellite cylinder 69 is led out through the opening of the side wall of the printing unit (not shown). The adjustment of the forme cylinders 65-68 to the transfer cylinders 61-64 in the respective positions is carried out by means of eccentric bushings 83-86. To stop printing, the eccentric sleeves 74-77, when printed from rubber forms, with the vertical movement of the paper web are moved to position 91 (for planetary printing, to positions 89 and 91). The eccentric sleeve 77 (Fig. 6) is arranged symmetrically to the sleeve 76, the eccentric sleeves 74 and 75 are symmetrical to the eccentric sleeves 76 and 77. To improve the setting of the transfer cylinders 61-64, the eccentric sleeves 74-77 are placed in subsequent eccentric sleeves.
    The holes in the wall in the printing section (FIG. 5) for the cylinders have the same position relative to each other, as do the corresponding holes in FIG. 1 and 3. As a result of this, the same sidewalls can be used to mount transposable printing units for planetary printing and printing from rubber molds with vertical, horizontal, or additional movements of the paper web.
    It is recognized as an invention according to the results of the examination carried out by the Office for the Invention of the German Democratic Republic.
