Definitions

  • the invention relates to a method for closing the gaps which result between the end or edge regions of gravure printing plates when these are clamped onto a forme cylinder of a sheet-fed or roller rotogravure printing machine.
  • the gap to be closed is covered by a cover element by placing this cover element on the end sections of the intaglio printing plate and pressing the cover element against the surface of the intaglio printing plate flush with the adjacent surfaces of the intaglio printing plate, the resulting gap cavity is filled with a hardenable sealing compound and after hardening the sealing compound removes the cover element.
  • the forme cylinder is generally provided with a groove running parallel or also obliquely to the forme cylinder axis, into which the intaglio printing plate is hung and held with at least one folded end.
  • Corresponding clamping cylinders are described for example in DE-A-25 45 124, DE-A-26 33 445 and DE-A-30 49 143.
  • the resulting gap between the two ends of the gravure printing plate must be closed in a suitable manner for the printing process in order to prevent the penetration and splashing of printing ink and to ensure that the doctor blade runs properly.
  • a hardenable sealing compound preferably made of a plastic
  • the gap area between the plate ends has been subjected to surface treatment, for example by grinding, so that in the area of the plate ends a continuous, even surface was created (Deutscher Drucker, No. 41 / 6-11-1975, pp. 17 to 22).
  • the work involved is relatively large and requires manual skills.
  • Cylinders require separate shaped beams, i.e. a change in the cylinder size is not easily possible. Furthermore, it is very difficult to compensate for tolerance fluctuations in the winding plates, but this is necessary for an exact gap closure.
  • tension cylinders therefore do not have an ideal line of curvature in the area of the suspension groove - over the entire or only part of the axial length, but rather more or less pronounced shoulders are shown here.
  • mechanical post-treatment of the closed gap may also be necessary according to the method of EP-A-118 866.
  • a separate operation is necessary for the gap closure according to the previously known and proposed methods.
  • the object of the present invention was to further improve the known and proposed methods for closing the gaps between the end or edge regions of rotogravure plates clamped on forme cylinders of rotogravure printing machines, so that a method results which is universally applicable with simple feasibility and at the same time guarantees and ensures a high quality of the gap closure.
  • the invention accordingly relates to a method for closing the gaps between the end or edge areas of gravure printing plates clamped on forme cylinders, in which the gap by means of a cover element by placing this cover element on the end or edge portions of the gravure plate and pressing the cover element against the surface the intaglio plate with the adjacent surface sections of the intaglio plate, the resulting gap cavity is filled with a hardenable sealing compound, and after the sealing compound has hardened, the cover element is removed.
  • the method according to the invention is characterized in that a cover element is used in which at least the surface area lying on the end or edge portions of the gravure printing plate and covering the gap can be deformed under pressure and can thus be adapted to the surface contour in the gap area.
  • the measures according to the invention allow any gap in the surface area of rotogravure plates clamped on forme cylinders to be closed well and permanently in a simple manner without mechanical post-treatment being necessary, irrespective of whether irregularities in the surface contour in the radial and / or axial direction in the gap area Deviations from the ideal surface line of the forme cylinder occur.
  • the method according to the invention can be used with the same advantage in clamped gravure winding plates, where there is only an axially extending gap extending over the entire cylinder width between the ends of the plate, as well as in cylinders on which several gravure plates are clamped one behind the other and next to one another this also results in gaps to be closed in the circumferential line between the lateral edge regions of the individual plates.
  • cover elements used according to the invention can be designed in different ways. It is essential that at least the surface or the surface area of the cover element, which covers the gap of the rotogravure plate, is deformable under pressure and thus adaptable to the contour in the gap area.
  • the cover element as a whole must be so stable that it can be sufficiently firmly pressed onto the surface of the rotogravure plate to ensure that the covered gap cavity is sealed.
  • Transparent cover elements are particularly advantageous, since this greatly facilitates inspection when the gap cavity is filled with the hardenable sealing compound and when this sealing compound hardens; If light-curable sealing compounds are used, the sealing compound can also be irradiated with actinic light for curing without removing the cover element.
  • the cover elements can be designed to be solid, for which purpose, for example, round or square strands in cross-section or other profile pieces that cover the gap between the end or edge regions of the stretched intaglio printing plates in sufficient width and over the entire length come from a material deformable under pressure, such as Silicone rubber, foams or the like exist.
  • hollow bodies are considered as cover elements which contain a pressure-generating and -transmitting medium, which is optionally connected to a pressure medium source.
  • cover elements are, for example, tubes, balloons or the like, or also multi-sided rigid, for example box-shaped elements that cover the gap, in which only the surface resting on the end or edge portions of the gravure printing plate and covering the gap from a deformable under pressure Material, e.g. a rubber-like or elastomeric material or in particular a film that can be changed in its tension state.
  • An intaglio printing plate 2 is clamped onto the forme cylinder 1 of a sheet-fed or roller rotogravure printing machine by, as can be seen in FIG. 1, the two folded ends 3 of the intaglio printing plate 2 being hooked into the groove 5 of the forme cylinder 1 via the beak edges 4.
  • the groove 5 for hanging the gravure printing plate 2 either runs parallel or at a slight angle, for example from about 2 to 5 °, to the forme cylinder axis and can - as shown in the example - widen from the cylinder surface to the cylinder center, so that the folded ends 3 of the gravure printing plate 2 are hooked into the groove 5 at an acute angle.
  • the side surfaces of the groove 5 can also run parallel to one another either perpendicularly or obliquely with respect to the cylinder surface, so that the ends 3 of the gravure printing plate 2 can also be folded vertically or at a different angle.
  • a cover element 8 is placed on the end sections 7 of the intaglio printing plate 2, which lies on the end sections 7 of the gravure printing plate 2 and covers the gap 6 in its entire axial length .
  • the cover element 8 is pressed against the surface of the gravure printing plate during the closing of the gap 6, for example with the aid of a hold-down device not shown in the drawing.
  • FIG. 1 illustrates the use of a rigid, box-shaped cover element 8, the one surface 9 of which lies on the end sections 7 of the gravure printing plate 2 is formed from a material that can be deformed under pressure.
  • a material that can be deformed under pressure for example, elastically stretchable films, such as rubber-elastic membranes or the like, other films, in particular made of plastics, which are movably clamped onto the box-shaped cover element 8 and whose tension state can advantageously be changed.
  • the foils stretched in this way can be stretched tightly by pressure from inside and / or outside, thereby forming a tight and flush cover with the end regions 7 of the depth pressure plate 2 can be adapted to the surface contours in the area of the gap 6 and pressed.
  • the cavity 10 of the cover element 8 is filled with a pressure-generating and transmitting medium and is advantageously connected to a pressure medium source 14 via a feed line 11.
  • a pressure medium source 14 for example, liquids, such as water, oil or the like, but in particular air or other gases, are suitable as pressure-generating and transmitting medium.
  • FIG. 2 schematically shows the covering of the gap 6 between the end sections 7 of a gravure printing plate 2 clamped on a forme cylinder 1 by means of a completely deformable cover element 8.
  • the cover element 8 is a hollow body, for example a hose, the cavity 10 of which is filled with a pressure-transmitting medium, for example a liquid such as water or oil, but in particular with air or another gas.
  • the cover element 8 is pressed by means of a suitable pressure piece 12 covering the gap 6 onto the end sections 7 of the rotogravure plate 2 that is clamped.
  • the pressure piece 12 is, for example, very advantageously an elastic, flexible plate, which is preferably transparent and is made, for example, of plastic.
  • the contact pressure with which the cover element 8 is pressed by the pressure piece 12 onto the surface of the clamped gravure printing plate is largely determined by the internal pressure of the pressure-transmitting medium in the cavity 10 of the cover element 8 and the desired shape for the closed gap surface.
  • the cavity 10 of the tubular cover element 8 similar to that shown in FIG. 1, can be connected to a pressure medium source via a feed line, so that in this case the internal pressure of the cover element 8 is also controlled, and thus further control of the adaptation of the cover element 8 to the Surface contours in the area of the gap 6 is possible with targeted adjustment of the desired surface line of the closed gap.
  • the gap cavity formed after covering the gap 6 with the cover element 8 is filled with a hardenable sealing compound.
  • the sealing materials used here are the materials which are customary and known per se for the gap closure and which, when cured, are resistant to the printing ink solvents.
  • these advantageously include hot melt adhesives based on, for example, polyvinyl acetate, polyamide, polyester or thermoplastic plastics, such as polyolefins, styrene-butadiene and / or isoprene block copolymers, etc.
  • thermosetting or, in particular, light-curing Reactive resins such as epoxy resins, acrylate, isocyanate, silicone c onharze, UP resins, etc.
  • Flowable, solvent-free, photopolymerizable mixtures based on photopolymerizable monomers, at least one polymeric binder, a photoinitiator, and, if appropriate, fillers and other additives are also very inexpensive as sealing compounds.
  • the material for the surface of the covering element 8 covering the gap 6 is chosen with regard to the hardenable sealing compound used so that after the sealing compound has hardened, the covering element 8 can easily be lifted off the surface of the gravure printing plate 2 and the hardened gap filling.
  • the cover element 8 can be surface-coated with a release agent, for example siliconized, or a thin release film can also be placed between the end sections 7 of the intaglio printing plate 2 and the surface of the cover element 8 lying thereon.
  • the groove cavity 5 In order to prevent the hardenable sealing compound from penetrating into the interior of the forme cylinder 1, in particular into any clamping devices and elements, the groove cavity 5 must be directed radially inwards, i.e. towards the cylinder center, tightly sealed. This closure of the groove cavity 5 radially inward can be achieved and ensured by purely design features of the forme cylinder 1, as is indicated schematically in FIG. 1.
  • a sealing element 13 can be used to close off the groove cavity 5 radially inwards the groove cavity 5 is inserted and extends over its entire length.
  • This sealing element 13 can be compact or, as shown in the drawing, a hollow body, preferably round in cross section, e.g. a hose made of silicone rubber. If hollow bodies of this type are used as the sealing element 13, they can be connected to a pressure medium source via a further feed (not shown in the drawing) and can thus be inflatable. As a result, both a secure and reliable seal can be achieved and any shrinkage of the filling material that occurs during curing can be compensated for.
  • the sealing element 13 which is designed as a hollow body, this can be switched into a pressurized heating or cooling medium circuit in order, depending on the filling material used, to additionally determine the flow behavior of the filling material when filling the gap 6 and / or or to be able to control and influence the curing of the filling material after the gap 6 has been filled.
  • the gap cavity covered with the cover element 8 is filled with the hardenable sealing compound expediently from the end face of the forme cylinder via one or more feeds arranged in its bearing troughs.
  • the flowable, hardenable sealing compound is injected into the gap cavity by means of a metering device.
  • the flowable, curable sealing compound can also be introduced through a hollow body 13 lying in the groove cavity 5, which is provided along the gap 6 with one or more small openings opening into the cavity of the gap 6. This ensures a fast, even distribution of the sealing compound, which is important for a perfect gap seal.
  • the sealing compound is introduced into the cavity of the covered gap 6 through an opening which is located approximately in the center of the hollow body 13 in relation to its length.
  • a pressure that may be necessary in the hollow body 13 can be generated in the hollow body 13 by means of the sealing compound in order to achieve a secure seal of the groove cavity 5 radially inward toward the cylinder center.
  • the air in the gap is displaced by both ends of the gap, which are only acted upon by the sealing compound at the end of the injection process.
  • the pressure with which the surface 6 of the cover element 8 covering the gap 6 is pressed against the end sections 7 of the intaglio printing plate 2 is of course greater than the pressure exerted on the cover element 8 by the injection of the hardenable sealing compound. This ensures that the gap 6 is covered flush and tight to the outside. Characterized in that the surface of the cover element 8 covering the gap 6 is deformable under pressure, it adapts to the surface contours in the gap area.
  • the material for the surface of the cover element resting on the end sections of the intaglio printing plate is accordingly selected such that it can be deformed under the contact pressure for the cover element and can be adapted to the surface contour in the gap area, but not by the counterpressure in the gap cavity injected, curable sealing compound is changed.
  • the surface line of the gap filled with the sealing compound can be varied within certain limits and adapted to the shapes desired in each case.
  • the control of the surface of the gap 6 filled with the sealing compound is essentially determined by the internal pressure existing in the cavity 10 of the cover element 8.
  • a gap closure with a fillet can be produced very easily and simply if the pressure in the cavity 10 of the cover element 8 is correspondingly high.
  • the movable, deformable surface 9 of the cover element 8 is not only pressed firmly and flush onto the end sections 7 of the intaglio printing plate 2, but at the same time is slightly curved outwards into the gap 6, so that in the gap area after sealing with the hardenable sealing compound a slightly concave surface results.
  • the surface line of the closed gap can be varied in a suitable and desired manner by suitable coordination of the external contact pressure for the cover element 8 and the internal pressure of the pressure-generating and transferring medium in the cavity 10 of the cover element 8, especially when a cover element 8 is used, the cavity of which 10 is connected to an external pressure source, via which the internal pressure in the cavity 10 can be controlled separately.
  • the sealing compound After the covered gap cavity has been filled with the sealing compound, it is hardened.
  • the sealing compound In the case of thermoplastics, the sealing compound is cured by cooling the molten polymers, in the case of thermosetting reactive resins by suitable heat supply, the heat sources being able to be arranged inside or above the gap cavity.
  • curing takes place by irradiation with actinic light, it being possible to use the radiation sources customary for actinic light.
  • the radiation sources for actinic light are generally arranged above the gap filled with the sealing compound and the hardening of the sealing compound generally takes place while the cover element is still resting on the end sections of the gravure printing plate and is pressed against it
  • the use of light-curable and photopolymerizable sealing compounds in particular cover elements made of transparent materials for the actinic light are used. Irradiation and hardening of the sealing compound filling the gap can thus take place through the cover element while it is still in place.
  • the pressure piece used in the case of completely deformable cover elements (FIG. 2) transparent.
  • the use of transparent cover elements is generally recommended, since this also makes it easier to observe the filling of the gap with the hardenable sealing compound and thus the inspection of the gap closure in general. After the sealing compound filling the gap has hardened, the cover element is then removed from the cylinder surface.
  • the gaps which result when clamping gravure plates onto forme cylinders can be closed in a simple manner so that no problems with sheetfed and in particular also with rollers - rotogravure printing, in particular with regard to doctor blade behavior, ink spraying or printing of the gap , to be watched.
  • Mechanical reworking of the gap closure is unnecessary, even with forme cylinders that are not exactly worked in the area of the hanging groove.
  • the surface line of the closed gap can be shaped and formed in the desired manner directly when the gap is closed without a separate operation.
  • the resulting gap seal is durable and durable and allows the high print runs required in gravure printing.
  • a particular advantage of the method according to the invention is also that gaps extending in the direction of the circumferential line of the cylinder, as e.g. arise when clamping several gravure plates side by side on a cylinder, can be closed easily.
  • all known and customary gravure printing plates that can be clamped onto the form cylinder of a sheet-fed or web-fed rotogravure printing machine, in particular also gravure winding plates, can be used.
  • These include the conventional gravure plates made of metal with Ballard skin as well as, in particular, the gravure plates with plastic print layers, in which a plastic layer is applied to a suitable print layer carrier, into which the ink-receiving recesses (cells), whether by mechanical engraving or Laser engraving (see e.g. DE-A-27 52 500 or DE-A-30 28 098) or photomechanically by imagewise exposure and development of a suitable light-sensitive recording material (see e.g.
  • rotogravure plates are therefore to be understood both as printing plates with wells as well as blank plates in which the wells have not yet been formed.
  • the gap between the plate ends can be filled again by mechanical processing or by tearing open with a wire previously inserted.
