Definitions

  • the invention relates to a device according to the preamble of the first claim.
  • tensioning devices are largely designed as tensioning rails which, for fastening the pressure plate with clamping means for clamping the pressure plate and with tensioning means, e.g. Screws are provided. These protrude through the tensioning rails, are supported against a wall surface of a cylinder channel in which the tensioning device is arranged, and must be operated by the operating personnel. These clamping devices then make it possible to clamp a printing plate of a certain length on the plate cylinder in the circumferential direction and, if necessary, to adjust it in the circumferential direction, e.g. when the pressure plate is crooked to the cylinder. Because the clamping rails are arranged in pairs in the cylinder channel, it is very time-consuming to fix the printing plate exactly on the plate cylinder in register.
  • a device (DE-PS 2 200 187) has already become known in which a pressure plate clamped in the tensioning rail can be quickly tensioned by a lever mechanism.
  • the tensioning rail is attached to a tensioning bracket and can be moved on the tensioning bracket using tensioning screws. Due to the lever mechanism that engages the clamping bracket, the pressure plate clamped in the clamping rails can can be tensioned by moving the clamping angle.
  • a spring arranged in this lever linkage should then also ensure during printing that the pressure plate is optimally tensioned.
  • this device has a lever drive for shifting the clamping angle and there is also an enlarged clamping path, it is not really suitable for fast clamping of pressure plates, since the clamping of the pressure plate is still carried out by the clamping screws in the clamping rails.
  • the invention is therefore based on the object of providing a device which enables printing plates to be clamped quickly and easily. Furthermore, printing plates with different lengths should also be clampable with this device.
  • the advantage of this device is that the actual tensioning of the pressure plate is done by spring force.
  • the springs are located in the tensioning rails and are supported on an angle rail. This angle rail enables the clamping range to be expanded in a simple manner so that printing plates with different lengths can be clamped.
  • the plate cylinder 1 of an offset printing machine (not to be explained in more detail here) has means in a cylinder channel 2 for fastening and tensioning printing plates.
  • These fasteners are designed as a front clamping rail 3 and rear clamping rail 4 and are each arranged at the start of pressure 5 and end of pressure 6 of the cylinder channel 2.
  • the tensioning rail 4 arranged at the printing end 6 is provided on an angle rail 7 which can be brought into different positions in the cylinder channel 2.
  • the tensioning rail 3 provided at the start of pressure 5 is arranged in a known manner in the cylinder channel 2 and is actuated by means of tensioning screws 8.
  • the rear tensioning rail 4 arranged on the angle rail 7 has a defined number of stepped bores 9, in which compression springs 10 are provided, which are supported on one leg 11 of the angle rail 7 and thus move the tensioning rail 4 towards the center of the cylinder channel.
  • the angle bracket 7 is fixed in position in the cylinder channel 2 by means of resilient bolts 12. These bolts 12 engage in bores 13 which are drilled at a parallel distance from the pressure end 6 in the cylinder channel 2. Through a number of several bores 13 provided one behind the other parallel to the printing end, the angle rail 7 can be arranged in different positions to the printing end 6.
  • the angle rail 7 has a leaf spring 15 in a recess 14, which supports the tensioning rail 4 when it bears against the leg 11 of the angle rail 7.
  • Both tensioning rails 3 and 4 are guided by longitudinal guides 17, 18, which are arranged on both sides of the cylinder channel 2.
  • the operation of the device is as follows: the pressure plate 19 is clamped in a known manner in the tensioning rail 3 and aligned with the tensioning rail 3 parallel to the start of pressure 5. The free end of the pressure plate 19 is then clamped in the rear clamping rail 4. The angle rail 7 is fixed in a bore 13 corresponding to the pressure plate length. By pressing down the leaf spring 15, the tensioning rail 4 is then pushed away from the leg 11 of the angle rail 7 by the force of the compression springs 10 and the pressure plate 19 is tensioned. The force exerted by the compression springs 10 ensures that the pressure plate 19 is always optimally tensioned.
  • pressure washers 21 are provided in the stepped bores 9 between compression springs 10 and the bottom 20 of the stepped bore 9, on which pressure screws 22 act. This type of configuration enables the clamping force to be increased when the pressure screws 22 are screwed in.
