Definitions

  • the invention relates to a roller with a rubber covering according to the preamble of claim 1 and a device for applying the rubber covering.
  • the disadvantage here is that the surface of the rubber covering must be treated, for. B. by grinding. This in turn leads to a relief on the surface, which causes irregularities in the transfer of liquid or pasty substances.
  • the invention has for its object to provide an ink or dampening roller with a rubber covering and a device for applying the rubber covering.
  • Figure 1 is a cross section with a schematic representation of an inking roller with rubber coating in a short inking unit and a device for applying the rubber coating.
  • Fig. 2 is a plan view of the roller of Figure 1 in an enlarged view.
  • FIG. 3 shows an enlarged detail according to FIG. 1.
  • a short inking unit 1 for a rotary printing press exists, for. B. from a ni chtda rste l Iten printing or rubber zli nde r, a forme cylinder 2, which 3 pasty printing ink is transferred from an anilox roller 4 by means of an inking roller.
  • the anilox roller 4 is supplied by a comb rrake Lei nri direction 6 with printing ink. Underneath the ridge of the comb 6, a collecting pan 7 is arranged.
  • the above-mentioned parts are stored side by side.
  • the inking roller 3, further referred to as roller 3, consists of a roller base body 8 with two shaft journals 9 which rotate about an axis of rotation 11.
  • a self-adhesive rubber blanket 12 for. B. with a thickness b of z. B. 2.3 mm.
  • a double-sided adhesive film or a adhesive can be provided with a thickness of about 0.3 mm. This ensures that the rubber blanket 12 is glued to the outer surface 12 over its entire underside.
  • the rubber blanket 13 is jacket-like and has a beginning 14 and an end 16. Beginning 14 and end 16 border after application to the roller 3 at a dividing or abutting line 17 (S umpf bump).
  • This abutting line 17, based on a unwound rubber blanket 13, extends at an angle alpha to a line 18 running parallel to the axis on the roller base body 8.
  • the angle alpha is between greater than zero degrees and six degrees, preferably three degrees.
  • a rubber blanket for a rubber blanket cylinder can also be applied at such an angle alpha.
  • the beginning 14 and end 16 of the rubber blanket 13 overlap one another, in the form of a stepped joint or a joint that has been used up.
  • tabs 14 and 16 each have tabs 21; 22 on, which are formed reduced in thickness and in a joint area 18, z. B. from five to ten millimeters on one egg.
  • the rubber blanket 13 is known and hand Isübli ch for use for rubber tuchzy li nde r in Offset rotary printing machines.
  • the rubber blanket 13 is applied as follows: a rubber blanket carrier, e.g. B.
  • a table 23 consists of a Prof i Lei sengest L L, which has two spaced longitudinal guides 24 - only one shown - which are connected to three transverse profiles 26, 27, 28.
  • the table 23 is z. B. covered with sheet 29.
  • the transverse profiles 26 and 27 are arranged directly to the left and right under the roller 3, so that a special spring action and good adaptation to the radius is achieved in this stripe-shaped area by means of the sheet 29.
  • the table 23 is pivoted in about half its length l by means of bolts 31 in the non-gesture line I ten page bar gesture L.
  • a rubber blanket 13 - broken line - is placed on the table 13, with the side provided with adhesive upward.
  • Parallel to the transverse profiles 26; 27, but on the other side of the sheet 29 can also be provided for the beginning 14 of the rubber blanket 13.
  • the end 32 of the table 23 remote from the roller is pressed in the lower direction D.
  • the roller 3 rotates in creep speed clockwise until the rubber blanket 13 is completely applied to the roller base body 8 after one rotation of the roller 3.
  • the table 23 is then pivoted upwards in the direction C or lifted out on the bolt 31. Between the three tabs 21; 22 is in the axial direction Le Le r direction z. B. fast l L k applied r adhesive and the tabs 21; 22 are placed one on top of the other with the side facing them and pressed together for approx. 10 to 20 seconds. Pressing can e.g. B. take place so that the table 23 rotated by 180 ° is hung on the bolt 31 that the end 32 is under the roller 3. In this case, a foam rubber strip 33 can be pressed onto the joint area 19.
  • the butt area 19 is then enlarged to a wider butt area 34 if the butt line extends at an angle alpha to the line 18.
  • the table 23 can also be moved by means of a frame, i. H. thus not be fixed to the side 11.
  • Fastening or positioning according to the register means that the joint area 19 or 34 of the cylinder 3, if possible, each with a pressure-free strip, for. B. a Z lindergrube 36 of the plate cylinder 2 corresponds. It is advantageous if the circumferential length of the cylinder pit 36 is greater than the area 34.
  • the roller 3 can be used as a rubberized inking roller or rubberized dampening roller for dampening systems.
  • the roller 3 is preferably each directly to a forme cylinder, for. B. the plate cylinder 2 adjustable.
  • the hardness of the rubber blanket is 65 to 70 Shore.
