Definitions

  • the invention relates to a cylinder for a rotary printing press with at least one pit, in which fastening means for receiving the ends of a blanket or a printing plate and an axially extending filler for covering the pit after inserting the ends of a blanket or a printing plate are provided.
  • the object of the present invention is to develop a cylinder for a rotary printing press with at least one pit in such a way that the printing plates or blankets can be fixed by means of fewer parts, the filling piece being intended to be supported on the cylinder material itself after the printing plate or the blanket has been fastened , so that the clamping and fastening means are not burdened by contact pressures from the adjacent cylinder.
  • Figures 1 to 4 show a first embodiment of the invention.
  • the ends of a rubber blanket 3 are fastened in a pit 2 on a rubber cylinder 1 of an offset rotary printing machine for printing webs.
  • these are provided with reinforcing strips 4 and 5, which are inserted together into a slot 6 of a clamping spindle 7.
  • Fig. 1 shows the rubber blanket 3 in a tensioned state.
  • This figure shows that the pit 2 is completely covered in this state by a filler 8, i. H. is closed.
  • Fig. 2 shows the filler 8 in the retracted state, in which the insertion of the reinforcing strips 4, 5 in the slot 6 is possible in a simple manner.
  • the filler piece 8 is then raised in an advantageous manner, so that its surface 9 adapted to the circular cylindrical contour of the rubber cylinder 1 adjoins the jacket of the rubber cylinder 1 smoothly.
  • the remaining slot in the pit 2 only corresponds to twice the thickness of the rubber blanket 3.
  • the filler 8 has fingers 14 spaced from one another, which in a first axial position of the filler 8 can be moved through or between corresponding fingers 15, which are fixedly arranged in the cylinder pit 2, so that the filler 8 can be moved into the position shown in FIG. 2 shown lowered position can be brought, in which the introduction of the reinforcing strips 4, 5 of the rubber blanket 3 takes place.
  • the fingers 15 are preferably worked out in the cylinder material itself.
  • the filler piece 8 has a lifting bar 10 which is preferably continuous in the axial direction and by means of which the filler piece 8 can be lowered and raised in the pit 2 in said first axial position.
  • the lever bar 10 is arranged in a slot of a rotatable guide tube 11, not specified, so that when the guide tube 11 is rotated, the filler piece 8 rises and falls accordingly.
  • Worm drive consisting of a worm wheel 12 and a worm 13, both of which can be arranged on the end face of the rubber cylinder 11.
  • the guide tube 11 protrudes over a corresponding extension of the same somewhat over the length of the blanket cylinder 1, so that the worm wheel 12 can be placed in a corresponding manner on its end face.
  • the guide tube 11 can be mounted in the rubber cylinder 1 in the usual way.
  • the clamping spindle 7 is at least partially rotated before the filler piece 8 is raised into the position shown in FIG. 1.
  • the filler piece 8 for which the eccentric drive shown in FIG. 12, consisting of an eccentric 29 and an axle journal 28 on the filler piece 8, which can also be arranged on an end face of the rubber cylinder 1, is used.
  • the fingers 14 of the filler 8 reach above the corresponding fingers 15 fixedly arranged in the cylinder pit 2, so that they can be supported on them.
  • the filler 8 is supported in the operating state in the cylinder itself, so that no loads on the lifting and shifting devices can occur and there is also no fear of bending of the filler 8, since the fingers 15 and 14 can be arranged over the entire cylinder pit 2, so that an even support is guaranteed.
  • the guidance of the filler piece 8 on the cylinder bottom, as can be seen from FIGS. 1 and 2, in conjunction with the rest of the design of the filler piece 8 ensures that the filler piece 8 cannot tilt. 3 and 4, the axial displacement of the filler 8 is indicated by a double arrow "P.
  • FIGS. 5 to 8 show a modified embodiment, in which only one reinforcement strip 4 of the rubber blanket 3 is arranged in a tensioning spindle 18, while the reinforcement strip 5 of the other end of the rubber blanket 3 is fixed in the pit itself.
  • the reinforcing strip 5 of one end of the rubber blanket 3 can be easily inserted.
  • a retaining strip 16 with a recess 17 extending in the axial direction is provided in the cylinder pit 2 in the area of the pit bottom for fixing it. If the clamping spindle 18 is slightly rotated, the reinforcing strip 5 is introduced through the peripheral region of the clamping spindle 18, which adjoins the flattening 19. When the clamping spindle 18 is rotated, the clamping spindle 5 is pressed into the recess 17, as can be seen from FIG. 6.
  • Fig. 7 shows the extended position of the filler 8, in which the blanket 3 is stretched.
  • a magnet system 20 is arranged on the clamping spindle 18, for example, which comes to lie in a certain circumferential position with respect to the reinforcing strip 5. If the reinforcement strip 5 is made of magnetizable material, the reinforcement strip 5 is attracted by the magnet 20 in this position, leaving the recess 17. If the clamping spindle 18 is now rotated slightly counterclockwise, the end of the rubber blanket 3 provided with the reinforcing strip 5 can be easily removed in accordance with the position shown in FIG. 8. Previously, in the position of the tensioning spindle 18 shown in FIG. 6, the end of the rubber blanket provided with the reinforcing strip 4 could be pulled out of the tensioning spindle 18 in a simple manner. In contrast to the embodiment shown in FIGS. 1 to 4, the tension of the rubber blanket 3 is now carried out according to FIGS. 5 to 8 via the end of the rubber blanket inserted into the tensioning spindle 18 and provided with the reinforcement strip 4.
  • the invention is suitable both for use on blanket cylinders of offset rotary printing presses and on plate cylinders of offset rotary printing presses and also in rotogravure form cylinders for clamping a so-called “winding plate”.
  • FIGS. 9 and 10 show, with the filler piece 8 retracted, the bent end 25 and the bent end 24 of a pressure plate 22 or a winding plate can be clamped onto a forme cylinder 21 which is equipped with a pit 23.
  • the bent end 24 of the offset printing plate or a winding plate 22 can be inserted into a recess 27 of a clamping spindle 26, which is indicated in FIG. 10.
  • the filler 8 is moved out so that it assumes the outer position shown in Fig. 9, in which the pit 23 is closed, i. H. is covered.
  • the clamping spindle 26 was previously rotated accordingly.
  • the filler 8 is guided on its right side directly through the clamping spindle 26 so that it cannot slip out of the slot of the guide tube 11.
  • FIG. 11 A particularly advantageous embodiment of a rubber blanket for use in the embodiments according to FIGS. 1 to 8 is shown in FIG. 11.
  • the rubber blanket 30 consists of a rubber blanket 31 and a fabric that is designated at both ends with 32 and 33.
  • the blanket cover 31 can now be removed at both ends, so that only the textile fabric 32, 33 remains.
  • reinforcement 32 or 33 reinforcement strips 34, 35 can be attached to the textile industry.
  • the length of the blanket cover 31 is now such that, taking into account the specific stretch of the blanket 30 in the stretched state of the blanket 30 on a cylinder, the abutting edges 36, 37 abut against each other over the remaining channel opening, which is virtually a «seamless or smooth and bumpless transition is formed and the impression of a continuous blanket over the entire circumference of the cylinder is created.
  • Another advantage of such a dimensioned blanket or blanket is that only the tapered ends of the blanket 30, that is Textile fabric 32, 33 is inserted into the pit, so that the remaining gap when the filler 8 is extended can be dimensioned so small that no more bumps are caused when rolling over, which are the cause of cylinder vibrations.
  • FIG. 12 shows the rubber cylinder 1, on the right side of which an eccentric pin 28 engaging in the journal 29 of the filler 8 can be seen, through which the filler 8 is axially displaceable, as indicated by the arrow "B.
  • a hexagon 38 is used to turn the eccentric. 12 also shows the worm drive 12, 13 for rotating the guide tube 11 and the worm drive (not shown in more detail) for rotating the clamping spindle 8.
