Definitions

  • the invention relates to a device for a slit-shaped holding device for attaching Plates, preferably blankets, with folded edges Ends in a narrow, axially extending slot Cylinder of a rotary printing press according to the Preamble of claim 1.
  • US-PS 25 25 003 a device for Attach one from a rubber blanket and one Carrier plate existing blanket unit described.
  • the rubber blanket unit has two folded ends provided, on each of which a beveled leg of the Support plate protruding over the ends of the rubber blanket is arranged and the rubber blanket on the carrier plate in each case in the area of a leg bounding Bending ends.
  • These chamfered legs are in introduced a narrow, approx. 3.5 mm wide slot.
  • Between opposite side faces of the two A wedge is arranged on the leg, with which a wedge is placed Leg pressed against a side surface of the slot becomes.
  • the blanket unit is thus by means of a Wedge-designed holding device in the friction Slit held.
  • DE 35 38 308 C2 shows a device for winding of a rubber blanket on a rubber cylinder Web rotary printing machine.
  • the rubber blanket with a dimensionally stable support plate to one Blanket unit connected.
  • a bent leg of the rubber blanket protrudes Carrier plate beyond the rubber blanket while on one leading end a beveled leg with the Blanket is coated.
  • These two ends of the Blanket unit are in a slot of the Rubber cylinder insertable so that the trailing End of the rubber blanket with its edge against the bent edge of the leading end of the Blanket unit comes close to the problem.
  • DE-PS 19 60 635 there is an arrangement for fastening of flexible printing plates on a plate cylinder shown.
  • the holding device described here consists of at least one axially extending one Shell of the plate cylinder introduced slot. Folded plate ends are made from this slot added.
  • a disadvantage of these devices is that between the both ends of the rubber blanket or the plate Narrow gap remains, which picks up dirt.
  • the invention has for its object a Device for a device for fastening a plate, preferably a blanket unit, in a narrow, axially running slot of a cylinder a rotary press to create the largely prevents dirt and ink in reaches the narrow slot.
  • the advantages which can be achieved with the invention consist in particular in that a gap remaining between two ends of a rubber blanket is largely closed and nevertheless a fastening of rubber blanket plates is possible.
  • the filler of the device according to the invention protects the free ends of the rubber blanket on the carrier plate against unnecessary wear.
  • the already small vibrations, which are reduced by the narrow slot, are further reduced as a result of the channel runout.
  • the advantages of the plate-shaped rubber blankets can be used without having to accept the disadvantages of the rubber blanket sleeves.
  • the device according to the invention is in the drawing shown and is described in more detail below.
  • a cylinder e.g. B. a rubber cylinder 1, one Rotary printing press is for recording
  • a blanket units 2 Panels with folded ends 3, 4 with at least one parallel to its axis of rotation, from a lateral surface 6 of the rubber cylinder 1 in Interior 7 extending narrow slot 8 is provided.
  • the rubber blanket 11 is fastened to the carrier plate 9 in such a way that both legs 12, 13 of the carrier plate 9 are free of the rubber blanket 11 at the bent ends 3, 4 of the rubber blanket unit 2 and thus only the two legs 12, 13 of the carrier plate 9 into the slot 8 protruding.
  • the slot 8 is preferably rectangular in cross section.
  • a bore 18 running parallel to the slot 8 is made in the rubber cylinder 1.
  • the slot 8 tangent to the bore 18 in the form of a chord, so that the bore 18 is connected to the slot 8.
  • the pressure pieces 23 are fastened in the spindle 22 in such a way that their pressure cams 24 can act resiliently beyond a lateral surface 26 of the spindle 22.
  • the pressure cams 24 are provided with a ball cap at their outer end, but configurations in the form of cylindrical segments are also possible, so that, for example, a linear contact zone results for each pressure cam 24.
  • an end 31 of a flexible but pressure-resistant leaf-shaped slide 32 is suspended, which in the present example is designed as a continuous steel leaf spring.
  • the other, outward-facing end 30 of the slider 32 is connected to a filler 33 in a form-fitting and / or cohesive manner.
  • the slider 32 can also be designed like a comb, the filler 33 can be attached to the back of the comb.
  • This filler 33 consists, for example, of an elastic material similar to the rubber blanket 11 which is vulcanized directly onto the end 30 of the slide 32 and extends axially along the length of the slot 8 or preferably over the entire width of the rubber blanket unit 2.
  • This filler 33 but can also consist of the same material as the slide 32 and be molded directly onto it. But it is also possible to form the slide 32 resilient, in which, for example, the end 30 is made of elastic material.
  • the slide 32 is provided on its side surface 34 facing the trailing end 4 with at least one barb 36.
  • a plurality of barbs 36 can also be arranged, which engage in corresponding recesses 37 in the leg 13 of the trailing end 4 which are adapted to the barbs 36.
  • the operation of the device according to the invention is as follows: In an insertion position (FIG. 1) of the spindle 22, the slide 32 located in the slot 8 with the filler piece 33 projects beyond the lateral surface 6 of the rubber cylinder 1.
  • the folded ends 3, 4 of the rubber blanket unit 2 are adapted to the angle of inclination alpha of the slot 8.
  • the spindle 22 is rotated counterclockwise until the pressure pieces 23 are approximately perpendicular to the legs 12, 13 of the carrier plate 9.
  • the pressure cams 24 of the pressure pieces 23 are pressed against the legs 12, 13 of the carrier plate 9 by means of spring force which is supported on the spindle 22.
  • the slider 32 with the filler 33 attached to it and the leg 13 of the trailing end 4 attached to the barb 36 is withdrawn into the slot 8 until the filler 33 fills the remaining gap 47 of the opposite ends 44, 46 of the rubber blanket 11.
  • the legs 12, 13 of the carrier plate 9 and the slide 32 are clamped in the slot 8 of the rubber cylinder 1 between the side surface 21 of the slot 8 and the pressure cam 24 (FIG. 2), with which the ends 3, 4 of the rubber blanket unit 2 are secured are attached to the rubber cylinder 1.
  • the spring force and spring travel are dimensioned such that a secure clamping takes place.
  • Compression spring 23 can also for example arranged in the circumferential direction, Prestressed leaf springs that over the lateral surface 26 protrude from the spindle 22, be arranged.
