Definitions

  • the invention relates to a method for applying a spacer material to printed sheets and a sheet-fed printing press equipped to carry out the method.
  • the application of a spacer material to a printed sheet pursues the goal of protecting the printed image from damage which can occur in particular in a delivery of a sheet-fed printing press when a delivery stack is formed.
  • the object of the present invention is to provide a method or a printing machine equipped for carrying it out, which eliminates the aforementioned disadvantages and, in particular, achieves good and damage-free alignment of a stack of printed printed sheets.
  • the advantage of the solution according to the invention is that the spacer material is not applied over the entire surface of the sheet, but rather only selectively. On the one hand, this saves spacer material, and on the other hand, the punctiform spacer particles applied when the sheets are stacked ensure that air cushions form between the individual sheets, which enable the stack to be easily aligned without damaging the printed image on a particular sheet and are easy to process ensure the same.
  • the spacer particles preferably have a size of approximately 5 to 30 micrometers and are randomly applied to the sheet at a mutual mean spacing of 50 to 400 micrometers in such a way that an at least almost equal number of spacer particles is present on mutually identical partial surfaces of the surface of the sheet.
  • the average distance selected from the range of 50 to 400 micrometers specified depends on the desired coverage density of the spacer particles, depending on the print image present, the consistency of the colors used for its creation and the nature of the print medium used.
  • the spacer particles are mixed with the printing ink or the dispersion varnishes used to refine the printed surface of the sheet and then applied together on the sheet. Additional devices for applying the spacer particles can thus be dispensed with.
  • the spacer particles are fixed on the sheet by automatically gluing them using the printing ink or the lacquer in the course of drying them.
  • the refining properties, in particular of the lacquer, in particular its contribution to increasing the gloss, are not impaired if the size of the particles of the spacer does not exceed a certain level.
  • An upper limit for this dimension can be set at around 10 micrometers.
  • the spacer particles of the paint or lacquer are preferably mixed in a ratio of 1:10 to 1: 100.
  • a further advantageous embodiment of the method is characterized in that water and a water-soluble adhesive are added to the spacer and that this mixture is applied to the sheet (1) in the form of individual spacer particles (2) with a coating of water and adhesive.
  • spacer particles (2) indirectly via at least one printing unit cylinder or be applied directly to the sheet.
  • a further preferred embodiment is characterized in that the spacer material is provided in the form of spacer particles (2) with a coating of water-soluble adhesive, and that when the spacer particles (2) are applied, the adhesive is activated by moistening to remove the spacer particles on the sheet (1) to fix.
  • wax is preferably used as the spacer, which is applied to the sheet in the form of wax particles.
  • a process variant based on this is characterized in that the wax particles (2) are obtained from a melt, drops being separated from them for application, and that the wax particles (2) are fixed by partial penetration of the drop into the arch (1 ) or sticking to the surface of the sheet (1) and then cooling and solidifying.
  • Another variant of the method is characterized by the formation of a respective one of the wax particles in the form of a core from a first wax and one of the core surrounding sheathing from a second wax with a lower melting point than the first wax.
  • the coating is first melted on, while the strength of the core is maintained. Compared to the variant described above, it is advantageous here that the process can run with similar other advantages at lower values of the necessary temperatures.
  • the wax particles are provided in the form of powder and that the fixing is carried out by brief thermal treatment.
  • Another process variant is finally characterized in that an aqueous suspension containing the wax particles is provided and the wax particles are fixed on the sheet by brief thermal treatment.
  • a printing press for printing sheets in particular with an inking unit and with printing unit cylinders in the form of a plate cylinder, a blanket cylinder and a printing cylinder, is equipped with an application device for carrying out the method for punctually applying spacer particles formed from a spacer material to the sheet with a container for storage of the spacer material and with rollers in the form of a take-up roller for receiving the spacer material from the container and an applicator roller associated therewith, the printing cylinder or the applicator roller having an outer surface with a surface structure suitable for punctual application of the spacer material particles and formed by means of depressions.
  • An alternative to this equipment of the printing press mentioned is to equip it with an application device for the selective application of spacer particles formed from a spacer to the sheet with a container for storing the spacer and with rollers in the form of a pick-up roller for receiving the spacer from the container, one Applicator roller for punctual application of the spacer particles on the blanket cylinder or the printing cylinder and an intermediate roller arranged between the take-up roller and the applicator roller, at least one of the lateral surfaces of the impression cylinder, applicator roller and intermediate roller having a surface structure which is suitable for punctual application of the spacer particles and is formed by depressions.
  • the applicator roller is assigned to the printing cylinder and that the printing cylinder has the surface structure.
  • the surface structure of the impression cylinder has spherical-spherical elevations and valleys between them, representing the depressions, are dimensioned such that at least one spacer particle can be accommodated therein, while another preferred embodiment provides is that the applicator roller is assigned to the impression cylinder or the blanket cylinder, and that the depressions are provided in the outer surface of the applicator roller and are formed by means of cups adapted to the size of the spacer particles or at least substantially grooves running in the circumferential direction of the outer surface.
  • the application roller is the printing cylinder or assigned to the blanket cylinder and the depressions are formed in the lateral surfaces of the application roller or the intermediate roller by means of cups adapted to the size of the spacer particles or at least essentially grooves running in the circumferential direction of the lateral surface.
  • the above-mentioned adaptation of the cells to the size of the spacer particles is carried out in a particularly advantageous manner in such a way that a respective cell is dimensioned such that it can accommodate a spacer particle.
  • the desired distribution of the spacer particles transferred to the sheet can be brought about directly by the distribution of the cells.
  • the depressions have a hydrophilic surface and are surrounded by hydrophobic surface areas.
  • the pick-up roller has an elastic jacket surface
  • a further embodiment which is advantageous in particular with regard to regulating the mean mutual spacing of the spacer particles, is distinguished by a difference in the peripheral speeds of the rollers of the application device.
  • a further development of the invention is characterized in particular by a printing machine having an inking unit and printing unit cylinder in the form of a plate cylinder, a blanket cylinder and a printing cylinder for printing sheets by a spray device which sprays a spray liquid formed by the spacer onto one of the printing unit cylinders or the sheet one Storage container for the spray liquid, a nozzle, a pump which supplies the spray liquid from the storage container to the nozzle, two mutually parallel, gap-forming rollers which limit a spray cone emerging from the nozzle, and with a cleaning device assigned to the two rollers, the Remnants of the spray liquid adhering to the rollers are removed from the rollers and returned to the storage container.
  • the nozzle can be pivoted, the application of the spray liquid being interrupted by pivoting the nozzle.
  • rollers of the spray device are arranged so as to be displaceable parallel to one another in order to be able to close the gap between them and thus to interrupt the application of the spray liquid.
  • a printing machine which has in particular an inking unit and printing unit cylinder in the form of a plate cylinder, a blanket cylinder and a printing cylinder for printing sheets is characterized by a spray device with a nozzle directed towards a printing unit cylinder, in particular the printing cylinder, and a container for storage a possibly a mixture with an adhesive-forming spacer and with a conductive plate, which is arranged such that the opening of the nozzle is in the space between the plate and the printing unit cylinder, an electrical field can be formed between the printing unit cylinder and the plate and at Activating this electrical field, particles of the spacer or the mixture are drawn from the nozzle to the printing unit cylinder.
  • the spacer material can be applied to the sheet and fixed there.
  • Spherical or teardrop-shaped wax particles with a size of 5 to 30 micrometers are preferably used as the spacer. This choice of size ensures that the wax particles are not visible to the naked human eye, that is to say that no changes in color, loss of gloss or other changes in the optical properties of a printed product are recognizable.
  • the waxes which are preferably used are, in particular, polyethylene waxes which, compared with today's powder materials, have good sliding properties which result from the fact that the wax liquefies at the surface pressure of the wax particles and forms a lubricating film.
  • the wax particles 2 are mixed with a dispersion lacquer 3, which is used to refine the surface of the sheet 1. This is preferably done in a ratio of 1:10 to 1: 100 (parts by weight).
  • the wax particles 2 are then applied accordingly to the sheet 1 previously printed with ink 5 using a coating unit.
  • the lacquer layer 3 applied to the paper for finishing acts like an adhesive for the wax particles 2, which holds them to the paper surface and fixes them on the sheet 1 during the drying of the lacquer layer.
  • FIG. 2a A further possibility of fixing a wax particle 2 on a sheet 1 is explained below with reference to FIG. 2.
  • the wax particles 2 are coated with an aqueous solution 4 of adhesive.
  • the dissolved adhesive has the task of fixing the wax particle 2 on the paper after it has been applied to the sheet 1. This happens because that after the application of the wax particle 2, the aqueous solution 4 runs and partially penetrates into the paper, as is shown schematically in FIG. 2b.
  • the wax particle 2 is thus fixed in a punctiform manner on the paper without the adhesive having an optically disadvantageous effect.
  • the wax particles 2 are used in the form of a powder or as part of an aqueous suspension without an adhesive component, there is a possibility within the scope of the invention for fixing the wax particles 2 on the sheet 1 following application to the latter by briefly heating the sheet 1.
  • a liquid film, possibly surrounding the wax particles 2, formed by the suspension evaporates, and that the wax particles 2 are melted on the surface, so that part of a respective wax particle 2 strikes into the paper and the wax particles 2 after cooling are fixed to the sheet 1.
  • the aqueous suspension mentioned can either be provided for application to the sheet 1 or can also be formed by mixing the wax particles 2 provided in powder form with the liquid portion of the suspension during the application of the wax particles 2. In any case, dust formation is avoided.
  • an indirect application can also be carried out by first applying the wax particles 2 to a roller and only then transferring them to the paper.
  • wax particles 2 are shown schematically, which are applied to the paper. A certain part of the wax of the wax particles 2, as indicated, has penetrated into the paper, with which the necessary fixation is achieved. After the wax particles 2 have a solid physical state at ambient temperature and thus cannot penetrate the paper, at least a part of the wax particle must be brought into a viscous state so that this part can penetrate the paper. This can be done on the one hand by a thermal treatment after the wax particles 2 have been applied. On the other hand, however, it is also possible to store the wax particles 2 as a melt before application. This requires a temperature of around 100 to 300 ° C.
  • drops of wax are formed, for example by means of a spraying device according to FIG. 9 or 12, and sprayed onto the sheet 1.
  • An initially melted wax drop cools during this time and increasingly solidifies.
  • part of the not yet fully solidified wax penetrates the paper and, after a further certain cooling time and associated solidification, causes the wax particles 2 to form from the wax drops and fix them on the sheet 1.
  • a modification of the previously described method is that a wax melt is again used for fixing on the paper, but in which wax particles are in at least almost solid aggregate state. This can be achieved by using two waxes with different melting points, the fixing wax having a lower melting point. The wax particles separated from the melt and then encased with a coating made of the wax with a lower melting point are fixed in place, as in the example described above, by penetrating the melted wax into the paper and then solidifying it.
  • thermal fixation Another possibility of a thermal fixation is to coat the wax particles 2 with a hot melt adhesive and to heat the wax particles 2 applied and thus coated.
  • the temperature provided for this must correspond exactly to the melting point of the hot melt adhesive, which is then used for fixing.
  • the melting point of the wax particle 2 should not be reached in order to prevent it from melting.
  • a water-soluble adhesive can be used for this. This adhesive can then be activated by targeted moistening on the surface of the sheet. Due to the water absorption capacity of the paper forming the sheet the water is removed from the adhesive and the wax particles are then fixed on the surface of the sheet.
  • FIG. 4 is a diagram of a part of a printing press for printing on the sheets 1.
  • a printing unit 25 and an adjoining delivery arm 21 are shown.
  • the printing unit 25 comprises a printing cylinder 12, a blanket cylinder 15 and a plate cylinder 16, around which an inking unit 18 and, in the case of operation of the printing machine in the wet offset process, a dampening unit 17 are grouped.
  • a respective sheet 1 is fed to the impression cylinder 12 by means of a sheet guide cylinder 19.
  • the printing cylinder 12 is assigned an application device 11 with an application roller 13 and a take-up roller 14, which picks up a suspension of water, adhesive and spacer particles 2 provided therein from a storage container 24.
  • the pressure cylinder 12 according to FIG Spacer particles 2 contained in the suspension are forced to have their desired distribution.
  • the layer thickness of water and adhesive in the non-recessed areas of the outer surface of the printing cylinder 12 is too small to allow any appreciable transfer of adhesive by liquid splitting onto the paper effect.
  • the spacer particles 2 in the depressions 31 adhere to the paper due to the water-soluble adhesive.
  • the application roller 13 can either have the diameter of the printing cylinder 12 and a corresponding cutout for the grippers of the printing cylinder 12. However, it can also be designed with a smaller diameter and can be turned on and off, for example by means of a cam control, in order to avoid the grippers of the pressure cylinder 12 in the parked state.
  • FIGS. 6a and 6b each show a diagram of a part of a printing press which essentially corresponds to that shown in FIG. 4.
  • the application device 11 is, however, not assigned to the printing cylinder 12 but to the blanket cylinder 15, whereby according to FIG. 6a it is placed with respect to this in such a way that first color and then the spacer particles 2 on the Blanket cylinder 15 are transferred. This sequence is reversed in the arrangement according to FIG. 6b.
  • the outer surface of the application roller 13 of the application device 11 is provided with a certain surface structure in the exemplary embodiments according to FIGS. 6a and 6b in order to punctually remove the spacer particles 2 and with the desired distribution already explained by means of a to apply the blanket cylinder 15 stretched blanket on the paper.
  • the lateral surface of the application roller 13 is provided with cups 27. These cups 27 are dimensioned such that a spacer particle 2 can be picked up with a little water-soluble adhesive.
  • the surfaces of the wells 27 are preferably hydrophilic, while the remaining surface portions of the outer surface of the application roller 13, which come into contact with the rubber blanket of the blanket cylinder 15, preferably have a hydrophobic property, for example due to a special coating.
  • the spacer particles 2 or the suspension are removed from the storage container 24 by means of the pick-up roller 14 and fed to the applicator roller 13.
  • the wells 27 fill with the spacer particles 2 or with the suspension, while the non-recessed outer surface regions of the application roller 13 remain uninvolved in the transfer of the spacer particles 2.
  • the desired distribution of the spacer particles 2 is determined here by a corresponding distribution of the cups 27 in the lateral surface of the application roller 13.
  • the pickup roller 14 is preferably provided with an elastic jacket surface.
  • the contact pressure between the applicator roller 13 and the take-up roller 14 is set such that most of the liquid is squeezed out of the well again when a well is filled without spacer particles 2. This process is illustrated schematically in FIGS. 7a and 7b.
  • FIG. 7a shows the case of a cup filling without spacer particles 2.
  • This curvature has the effect that any liquid, in particular water-soluble adhesive, which may be in the well 27 is squeezed out when there is no spacer particle 2 in the well 27. This prevents adhesive dissolved in water from being transferred without spacer particles 2 and the printed product thereby being impaired optically.
  • FIG. 7b shows the case in which a spacer particle 2 is located in one of the cups 27 of the application roller 13.
  • the spacer particle 2 ensures that the elastic outer surface of the take-up roller 14 bulges toward its axis, as is indicated schematically in the figure.
  • the drive of the two rollers 13, 14 can be designed so that there is preferably a low relative speed between these two rollers, the relative speed being variable.
  • the advantage here is that the wax particles 2 more easily get into the wells 27 due to the friction between the two roll surface areas.
  • the application device 11 'shown in FIG. 8b is slightly modified compared to the application device described above.
  • the suspension taken up by the take-up roller 14 is not transferred directly to the application roller 13, but first to an intermediate roller 30, from which the transfer to the application roller 13 then takes place.

  • the way in which the wax particles 2 are received and passed on to the applicator roller 13 or to the blanket cylinder 15 essentially corresponds to that of the lateral surface provided with cups 27.
  • the desired distribution of the wax particles 2 is in this case achieved by a suitable choice of the distances between the grooves 32 and a peripheral speed of the intermediate roller 30 which then deviates from that of the applicator roller 13.
  • the applicator roller 13 has the applicator roller 13 the peripheral speed of the blanket cylinder 15 and the intermediate roller 30 a lower peripheral speed, so that in the individual Grooves 32 of the intermediate roller 30 lying wax particles 2 transferred to the applicator roller 13 at a distance which is increased compared to a distance between the wax particles 2 located in the grooves 32.
