Definitions

  • the invention relates to a device for fastening a flexible covering on a printing cylinder according to the preamble of claim 1.
  • the intermediate piece requires increased manufacturing and assembly costs as well as a larger dimensioning of the channel adapted to it.
  • the invention has for its object a device for attaching a flexible covering on a printing cylinder of a rotary printing press according to the preamble of claim 1 to provide a Reduction of the manufacturing and assembly effort is simply designed.
  • the lateral guidance of the sprag outside the channel allows under Elimination of one serving to support the compression springs of the clamping body additional intermediate piece a simple, inexpensive design of the Channel and the mechanisms contained in it.
  • FIG. 1 and 2 show a pressure cylinder 1 with a from a bore 2nd and two at an acute angle to the cylinder surface and there in one Slot 3 ending channel walls 4; 5 existing channel 6, in which one elongated, with a frustoconical cross section Clamping body 7 in the longitudinal direction by means of several recesses 8 of it guided compression springs 9 against the bottom of the channel 6 in the direction of the slot 3 supports (Fig. 3).
  • the pressure cylinder 1 has on both sides largely one to the channel 6 symmetrical, circular segment-shaped recess 10, in each case at one Long side of the channel 6 with a shoulder 11 projecting laterally Clamping body 7 adjacent support body 12; 13 are arranged by means of Through bores 14 penetrating with play, in threaded bores 15 of the cylinder body engaging screws 16 are attached (Fig. 1).
  • Fig. 1 enables the play between the through holes 14 and screws 16 a displacement of the respective support body 12; 13 transverse to the clamping body 7, so that the between the support bodies 12; 13 guided radially Clamping body 7 to the channel walls 4 u. 5 is adjustable
  • the paragraph 11 of the clamping body 7 has a vertical, radially directed Through hole 17 formed by one with its head on the clamping body 7 lying, engaging in a threaded bore 18 of the cylinder body 1 Set screw 19 an adjustment of the clamp body 7 to the channel walls 4; 5 is permeated with play through the support body.
  • the travel path of the Set screw 19 is radially outward through its head overlapping paragraphs 20; 21 the support body 12; 13 limited (Fig. 1).
  • FIG. 4 shows a printing cylinder 1 functioning as a transfer cylinder 22 which a rubber blanket 24 equipped with a flexible carrier plate 23 as Cover 25 is attached.
  • the clamp body 7 is over a corresponding displacement and subsequent fixation of the support body 12; 13 to one only slightly below the thickness of both ends 26; 27 lying, but ensuring their clamping minimum distance a between the Clamping surface 28 and channel wall 4 set (Fig. 1). That on the carrier plate 23rd vulcanized or glued rubber blanket 24 ends immediately at the respective Folding the ends 26; 27, so that the circumferential interruption of the Blanket 24 in connection with the narrow slot 3 in the sense of a Minimization of cylinder vibrations is small in operation.
  • FIG. 5 shows a printing cylinder 1 functioning as a forme cylinder 29, on which one flexible pressure plate 30 is attached as a covering 25.
  • the pressure plate 30 is beveled analogously to the carrier plate 23 and with its two ends 26 '; 27 'in the described way clamped in channel 6, one at the leading Channel wall 4 protruding into the channel 6, in a recess 31 of the Clamping body 7 engaging register pin 32 a register-correct seat Pressure plate 30 guaranteed.
  • the Set screws 19 especially the ends 26; 26 '; 27; 27 'of the covering 25; 25 'relieving actuation of the clamping body 7 radially inward when loosening the covering 25; 25 'from the impression cylinder 1 (Fig. 1 and 3).
  • the guidance of the clamping body 7 between the support bodies 12; 13 takes place in in any case such that the non-locked clamp body due to the spring force of the Compression springs 9 both on the channel wall 5 and in the channel 6 inserted ends 26; 26 '; 27; 27 'whose secure clamping is in effect.
