Definitions

  • the invention describes an apparatus and a method for producing counterfeit embossings, for refining printing substrate surfaces with coarse-grained pigments and for producing structural surfaces.
  • a disadvantage of the described method is that the printing and the application of the printing material with a structured powder, -ffen or with a flocking takes place in two steps.
  • DE 2719753 A1 discloses a printing machine for flocking a fabric web, wherein the printing press and a flocking machine are sequentially combined in a row to form a unit.
  • the last printing unit is assigned an adhesive applicator roll.
  • the textile web first passes through the printing units of the printing press, which imprints the different colors.
  • the last roller of the printing unit can be designed as an adhesive applicator roll, which provides the web for subsequent flocking with an adhesive application.
  • the web Immediately after leaving the adhesive applicator, the web enters a flocking unit synchronized with the printing unit, in which the web is flocked in the usual manner.
  • the adhered particles are primarily paper dust and release agents, e.g. Dusting powder that is sucked off the printing surface or removed in any other suitable way before printing.
  • the most common cleaning equipment had a rotating brush, which mechanically removes the particles from the substrate surface.
  • cleaning systems are combined with a suction device.
  • a printing machine having a cleaning system with a slot nozzle, which is connected to a suction air source. This slot nozzle is used for disposal of the on the surface of the substrates adhering particles. Parallel to the slot nozzle a compressed air line is provided, which is equipped with aligned in the direction of the substrate air outlets, which serves to dissolve adhering to the substrate particles.
  • a device which includes a blower blade for peeling off the particles adhered to the substrate.
  • this invention provides an ultrasonic generator for detaching the particles from the surface of the printing material. The cavitation generated by the ultrasonic waves exerts high mechanical forces on the particles adhering to the printing material and ensures reliable detachment of the particles.
  • the aim of the invention is special effects on substrates by the application of powders, dusts, pigments, metal particles u. to get similar.
  • the object of the invention is to define a method and a device which allows the application of structure forming dusts, pigments, flocking and the removal of excess material during the printing run by a sheet-fed rotary printing press.
  • the particle size is limited because the particles must pass the pressure column (s) in the roller mill and the nipples pressure plate / blanket and blanket / substrate.
  • the maximum particle size when using a chamber doctor blade is limited by the cup size and cup shape of the anilox roller.
  • the device according to the invention is arranged according to FIGS. 1 to 4 in a printing unit with a printing cylinder 1, a plate cylinder 2 and a blanket cylinder 3.
  • the device may be arranged in a coating unit, which also has a printing cylinder 1 and in which the plate cylinder is replaced by a forme cylinder 2. Then possibly eliminates the blanket cylinder. 3
  • an adhesive is applied in a structured manner via the printing unit or the coating unit (flexographic printing unit) of a sheet-fed rotary printing press, wherein the structuring corresponds to the later desired printing result.
  • the adhesive can be applied in the printing unit in which an application device (4) according to the invention and a suction device (5) according to the invention are installed.
  • the adhesive application in any of the devices of the invention (4, 5) upstream printing units can be applied.
  • the printing material partially provided with the adhesive is supplied to an application device (4) which applies the desired particles, preferably in excess, to the printing material guided on the printing cylinder (1).
  • the loading can be done by the particles are blown with blowing air or compressed air to the substrate by the particles are screened on the substrate or applied in another form.
  • the on-substrate particles which do not adhere to the pre-applied adhesive sites, are removed by a suction device (5) (Figs. 1 to 4), which sucks the excess particles from the substrate.
  • the application device (4) and the suction device (5) are directed against the impression cylinder (1) of a printing unit or a coating unit (FIGS. 1 to 4).
  • the suction device (5) is arranged downstream of the application device (4) in the direction of rotation of the pressure cylinder (1).
  • Application device (4) and suction device (5) can be arranged as individual devices or combined in one unit (FIGS. 1 to 4).
  • the devices (4, 5) can wholly or partially touch the sheet which is located on the printing cylinder (1). This allows the bow to be stabilized.
  • the sheet may be held on the printing cylinder by suitable holding means (e.g., rollers, brushes), these holding means preferably being placed in non-pressure zones.
  • suitable holding means e.g., rollers, brushes
  • these holding means preferably being placed in non-pressure zones.
  • a separate pneumatic blowing device would be conceivable.
  • the suction device (5) with a rotating brush (6) is provided which cleans the sheet and still exists on the sheet loose particles in the suction of the suction device (5).
  • this is achieved by the direction of rotation of the brush (6) is directed against the direction of rotation of the printing cylinder (1).
  • the sheet on the printing cylinder (1) is advantageously additionally struck.
  • one or more fixed brush rows can be arranged in the suction chamber of the suction device (5), which cleans the sheet of loose particles present on the printing cylinder (1).
  • the suction device (5) can be equipped with an ultrasonic oscillator (7) which releases the loose particles from the printed sheet by cavitation so that they can be sucked off without difficulty.
  • the ultrasonic vibrator (7) can be used alone or in combination with brush rows or a rotating brush (6).
  • the suction device (5) with a blowpipe or a Blasdüsengol (8) may be provided which loosen the loose particles on the substrate so that they can be easily and safely sucked off.
  • the blowing direction of the blower tube or the nozzle row (8) is directed in an advantageous manner against the direction of rotation of the printing cylinder (1).
  • a fixing and spreading of the printing material on the printing cylinder (1) is additionally achieved.
  • a combination with brushes is conceivable.
  • the particle application device (4) and the P can be followed by a heat source.
  • the heat source By means of the heat source, on the one hand, the adhesion of the particles is improved.
  • a melting or melting of the particles to assist in the formation of the desired patterning support.
  • an infrared radiator heated blown air or a directly or indirectly er ⁇ rmbare roller can be used.
  • the adhesion of the particles can be supported.
  • the desired structuring supportive be used.
