Definitions

  • the invention relates to a device for fastening printing blankets on transfer and blanket cylinders according to the preamble of claim 1.
  • a device for attaching the lowermost layer or the lower layers of multi-layer covers for transfer and blanket cylinders in which the blanket pad is pressed by a trapezoidal strip by means of spring force against a clamping surface of the cylinder channel and thus between the channel wall and Clamping surface of the bar is clamped.
  • the disadvantage here is that the bar must be adjusted by hand using a wrench.
  • US-A-26 21 592 shows a printing plate clamping and tensioning device. A clamping and clamping spindle is provided.
  • the invention has for its object to provide a device for attaching printing blankets to transfer or blanket cylinders in printing machines, with which an automatic and secure clamping of an underlying blanket pad is made possible when tensioning an overhead blanket and no additional tools are required.
  • the advantage of the device according to the invention lies in particular in that an automatic and safe clamping of the printing blanket under the tensioning of the printing blanket takes place without the need for an additional operation or the use of tools. Due to the design of the fastening device, the blanket pad has no possibility of slipping or moving.
  • the arrangement of a reinforcement profile on the terminal strip ensures that the clamping edge and the control edge are in even contact. As a result of the fact that the terminal block has radially arranged slots, the spring action of the terminal block is increased.
  • Fig. 1 shows a partial cross section of a blanket cylinder 1 for sheet-fed offset printing machines.
  • a channel 2 in which a tension shaft 3 with a slot 4 is arranged, runs parallel to the axis of the blanket cylinder 1, not shown.
  • an axially extending terminal strip 8 is fastened by means of screws 7, which has an essentially L-shaped cross section.
  • the clamping strip 8 has a clamping leg 9 running parallel to the channel side surface 6 and a control leg 11 running tangential to the tensioning shaft 3.
  • the terminal block 8 is made of resilient material. As can be seen from Fig. 1, a blanket pad 12 is inserted into a clamping point of the terminal block 8.
  • Fig. 3 it is shown how the blanket 13 is inserted with its end in the slot 4 of the tension shaft 3.
  • the end of the blanket 13 is fastened in a bar 14.
  • the tensioning shaft 3 has been moved in the direction of arrow B in relation to the illustration according to FIG. 2 by approximately 90 ° and the tensioning of the printing blanket 13 has started.
  • the blanket pad 12 was clamped automatically and without the use of tools by means of the clamping strip 8 during the movement of the tensioning shaft 3.
  • the blanket layer 12 or the blanket pads 12 are dimensioned in such a thickness that they are adapted to the diameter of the bearer ring 16 together with the blanket 13.
  • the other end of the printing blanket 13 is wrapped around the circumference of the entire blanket cylinder 1, not shown, at about 280 °, likewise clamped by means of a tensioning shaft.
  • a separate terminal block for the lower blanket pad 12 is not required.
  • Fig. 4 shows a view A from Fig. 1.
  • the terminal block 8 between its L-shaped legs 9, 11 has a reinforcing profile 17 which z. B. can be tubular in cross section.
  • the clamping leg 9 has radial, ie running in the direction of the blanket cylinder center slots 18, which leads to an improved spring action thereof.
  • the tension shaft 3 is on one side with an actuator equipped, which can consist of a worm wheel 19 with a worm 21.
  • the clamping device according to the invention can also be used for web offset machines.
