Definitions

  • the invention relates to a clamping and Pulling device for lifts of cylinders in Printing machines according to the preamble of claim 1.
  • Both terminal strips are based on the known one Arrangement against each other and against the frame and thus against the plate cylinder, one on one Terminal strip acting actuator the clamping forces on the Clamping jaws and two further actuators the clamping forces in Apply the circumferential direction of the plate cylinder to the frame.
  • An additional pressure roller is also required to to bring the plate onto the cylinder without a hollow position. Thereby is the effort for such a tensioning and pulling device quite high.
  • EP 0 563 601 A1 describes a clamping and Clamping device for a printing plate is known, in which for detection an angled end portion of the pressure plate provided under Preloaded gripping elements in the firing position and one Adjustment unit for opening the gripping elements arranged in a frame are, which is inserted into a channel of a cylinder.
  • the frame is with respect to the cylinder essentially radially inwards by means of springs biased and by means of further adjustment units against the effect of these Springs can be moved radially outwards into a position in which the Gripping elements in an open position of the same for receiving the stand angled end portion of the pressure plate.
  • the invention has for its object an inexpensive clamping and Puller design that is common to both cylinder lifts the front edge as well as the rear edge is suitable, and the one smooth application of the fold of the elevator to one if necessary channel edge having different radius enables.
  • the invention solves this problem with a clamping and pulling device the features according to claim 1.
  • the particular advantage of the device is that with the Clamp movement immediately a pulling movement in the tensioning direction of the elevator is exercised so that around the edge of the cylinder channel with one of the Edge radius deviating curvature against cylinder lift the cylinder edge is pulled.
  • the features of the invention make this possible Dragging the elevator around the channel edge. This avoids that a circumferential bead forms at the edge of the elevator because no air between the edge radius of the cylinder channel and the
  • the radius of curvature of the fold of the elevator remains.
  • a clamping and pulling device with these features is suitable for Printing plates, blankets and other cylinder lifts, preferably in Sheet-fed rotary printing machines.
  • the device can be used both for clamping the front edge of the elevator and the rear edge of the elevator and to simultaneous pulling of the ends of the elevator can be used. she is constructively in a confined space and has no susceptible to failure
  • the drawing shows an embodiment of the invention.
