Definitions

  • the invention relates to a printing unit cylinder, suitable for high, flexographic, low and web offset printing presses, which has a roller, a tensioning element with a narrowed tensioning channel and a rubber covering, the top layer of which is worn away so far at the channel ends that the remaining ends can be inserted into the tensioning element so that no channel opening is visible on the rubber surface when tensioned.
  • the rubber coverings should withstand the pressure, contain reinforcements with sufficient adhesion to the rubber layer, be easily replaceable and have a long service life, and have sufficient dimensional stability and uniform thickness.
  • Adhesive layers can be used to attach the rubber coverings to the cylinders, but this leads to unsatisfactory results.
  • An improved, but not yet optimal solution for rubber fixation is to set up mechanical holding systems, which are located in the so-called clamping channel of the cylinder. Measures must be taken to reduce or suppress the bending vibrations of the pressure cylinders at the channel inlet and outlet areas. Because the contact pressure between the cylinders increases the radius in the radial direction, starting from the reversible relaxation of the rubber blanket.
  • the channel impact or engaging shock then occurs when it rebounds onto the counter-rubber blanket or printing cylinder, which leads to vibrations in the printing system.
  • a gap remains open between the rubber blanket sections lying against the cylinder pit edges. Because of the above processes, the printing process negatively influenced.
  • European patent application 0 194 618, application number 86103093.3, filing date March 7, 1986, describes this behavior of the bending dynamics of two printing unit cylinders when the tensioning channels overflow, especially in web offset printing presses. It is proposed here to change the blanket or printing unit cylinders so that the axial edges of the tensioning channels are increased relative to the cylinder surface, and in this way the engagement impact or channel impact that occurs when the tensioning channels roll over is greatly reduced. These edge increases on the tensioning channel are achieved by tangential profile rails.
  • DE-OS 34 37 309.8 attempts to solve the problem of the impact joint or channel run through a special design and configuration of the stiffening strips on the front and rear edge of the rubber blanket on a rubber blanket cylinder.
  • US-A 2 629 324 relates to a method for producing a printing blanket which comprises a rubber layer on a metal layer.
  • the ends of the metal layer are longer than those of the rubber layer.
  • the printing blanket is used in printing unit cylinders, comprising a tensioning element with an insertion slot for the longer covering end.
  • Such rigid composite films have however, have a low kink resistance and are relatively sensitive to impact. The impact stress can lead to an irreversible deformation of the metallic carrier and thus the surface of the printing unit cylinder, which makes further use of the printing plate questionable.
  • the invention is therefore based on the object, the construction field clamping channel in the use form, i.e. with the rubber covering in place so that the total radius, taking into account the thickness of the rubber covering, is not increased and in this way there is no longer any impact or channel impact, the system should have good kink resistance and should not be sensitive to impact.
  • the tensioning system must be designed in such a way that the mechanical stability of the cylinder is reduced as little as possible, twisting of screws is not possible, and the surface of the rubber covering is evenly tensioned.
  • the object is achieved in that the upper layer of the rubber covering of a printing unit cylinder is removed so far at the ends and the remaining lower covering layer is then introduced into the tensioning system in such a way that no stretching channel opening is visible on the rubber surface taking into account the expansion.
  • the correction of the rubber covering ends together with the tensioning element according to the invention allows the tensioning channel to be changed so far, that a twist-free clamping system is created with which mechanically stable printing unit cylinders can be produced.
  • a printing unit cylinder for high, flexo, gravure and web offset printing which has a cylinder body (6), a rubber covering (1) - (5), the top layer (3) of which is shorter than the bottom layer (1) - (5), and further comprises a tensioning element (7) with an insertion slot (8) for the longer covering end of the rubber blanket, the upper shorter layer (3) of the covering with the lowest (1) - (5) an angle ⁇ smaller or forms 90 °, and the cylinder body (6) has a round recess, the insertion slot (8 ') of which corresponds to the insertion slot (8) of the rotatable and fixable tube (7) serving as a tensioning element (7), which is in the cylinder body (6 ) is attached and the radius corresponds to the inner radius of the recess of the cylinder body (6), the tube (7) having a portion (9) formed over 90 ° of the circumference and about 500 microns thinner in thickness.
  • a mechanically stable printing unit cylinder can be provided without channel runout and engagement butt, which enables the printing plate to be used further and has a long service life on the printing presses.
  • the claimed printing unit cylinder essentially consists of a roller, a tubular tensioning channel and a tubular tensioning element, each with insertion slots and a flat fabric, which, after being shortened at the channel ends in the tensioned state, completely covers the roller body.
  • it is not the entire backing layer rubber composition, which is usually used as a pressure coating, that is fixed in the tensioning device, but the main strength backing.
  • the mechanical stress in the tensioning channel region, in particular on the rubber-rubber joint, is then largely absorbed by the strength between the carrier layer and the rubber layer.
  • such a rubber covering is preferably selected which has a high strength between the carrier layer and the rubber layer and has good dimensional stability, so that the printing properties of the printing unit cylinder claimed are further improved.
  • composite films consist of a carrier layer, preferably a polyester film, such as e.g. Polyethylene terephthalate, which is crosslinked on one or both sides using known adhesion promoters, at least with a layer of NBR or other elastomers.
  • a carrier layer preferably a polyester film, such as e.g. Polyethylene terephthalate, which is crosslinked on one or both sides using known adhesion promoters, at least with a layer of NBR or other elastomers.
  • FIGS. 1-4 show four embodiments of such composite films which can be used as flat structures in the printing unit cylinder claimed.
  • (2) is the adhesive layer.
  • the backing layer (1) (preferably polyethylene terephthalate) can be cross-linked on one side with an elastomer layer (3) (Fig. 1), on one or both sides with one or two elastomer layer (s) (3 + 4) of different Shore A hardness ( Fig.2).
  • the flat structure can furthermore consist of a carrier layer (1), two elastomer layers (3 + 4) and a driven layer (5) arranged between them (Fig. 3), or also have an elastomer layer (4) with incorporated raster (Fig. 4) .
  • a rubber covering according to FIG. 1 is selected as a flat structure for the construction of the printing unit cylinder claimed.
  • the arrangement shown in FIG. 5 results between the roller body and the flat structure.
  • the upper layer in the example the elastomer layer (3)
  • the elastomer layer (3) is now at the clamping edges of the rubber covering, e.g. by planing, milling or grinding to such an extent that the part still occupied corresponds exactly to the circumference of the cylinder and the planed, milled or ground ends are of equal length.
  • the elastomer layer (3) is shortened again on one or both sides to the extent that the stretching under the tensioning force.
  • the situation shown in FIG. 6 results for the flat structure.
  • the elastomer mass (3) located above the base point B determines the extent of the increase in the total radius, ie the elevation depends on the angle ⁇ . If the angle ⁇ is 90 ° or more, there is no exaggeration, the purpose according to the invention is not achieved in the latter case.
  • the minimum channel width required to clamp the ends of the rubber covering remaining after abrasion of the layer (3) depends on the total thickness of the covering.
  • Printing unit cylinders for web offset printing (blanket cylinder), for high and flexographic printing (printing plate and impression cylinder) and also for indirect gravure printing (blanket cylinder) can be equipped with the rubber covering which has been corrected and subsequently fixed in the manner described.
  • the printing unit cylinder according to the invention consisting of a roller, a tensioning element with a narrowed tensioning channel and a flat structure laid out in the manner described, is also suitable for functioning as a flexographic printing roller.
  • the type of the new pressure element allows the elastomer covering to be replaced in the shortest possible time. It is even conceivable to do without changing the printing roller. This is possible if the subject is laser-engraved separately and the elastomer printing form component is placed and clamped on the printing roller or core installed in the machine. A prerequisite for such a mode of operation is the dimensional identity and the same mechanical behavior of the cylinder in the laser engraving unit and that in the printing press.
  • the surface of the rubber covering can also be designed in a known manner in relief, as is done in so-called cliché machines by pressing and vulcanizing.
  • the printing unit cylinder described is a printing form cylinder.
  • the elastomer plate joint can be closed with adhesives or a suitable adhesive.
  • the mechanical stability of a printing unit cylinder which in the conventional designs is due to the installation of the clamping elements and the cutout for the Clamping channel is reduced is not reduced in the claimed printing unit cylinder, because the rotatable part of the clamping device, the clamping element, together with the clamped carrier layer, fills the clamping channel and thereby stabilizes the printing unit cylinder.
  • Fig.8a The cylinder body (6) contains a round recess and the slot for the carrier layer (6/8 ').
  • Fig. 8b A tube with the same size slot (7/8) as (6/8 ') on the cylinder (6) serves as the tensioning element (7) and corresponds in radius to the cylinder recess (6). This tube is reduced in thickness by approximately 500 ⁇ m (9) over 90 ° of the circumference from the outside.
  • Fig. 8c The clamping element (7) is inserted into the cylinder body (6). If the slots (7/8) and (6/8 ') are one above the other, the rubber covering ends (10) machined according to the invention are inserted and provided with tensioning rails (11).
  • the advantage of the claimed printing cylinder is in the fact that no special devices are to be installed in order to bring about the exaggerations required to prevent the channel impact or interference.
  • the correction of the rubber covering ends according to the invention can be carried out in a simple manner (planing, milling, grinding) and in the laid-on state.
  • a simple manner plane, milling, grinding
  • twist-free clamping elements and thus mechanically stable printing unit cylinders can be created.
  • the printing unit cylinder can be used in web offset printing (blanket cylinder) in indirect gravure printing (rubber cylinder), in high and flexographic printing (impression cylinder) or also in flexographic printing (printing form cylinder, flexographic printing roller).
