  • the wells passing through the well in the lateral surface are filled with gravure ink. Excess paint is stripped off by at least one squeegee against the jacket surface.
  • the DE 10 2004 056 631 B3 shows a splash guard with scraper, which in each case in the transition region from the gravure cylinder to the axis on which the gravure cylinder is mounted, is arranged. In this case, drops of paint detaching from the rotating axis can be largely intercepted by the splash guard.
  • the DE 10 2004 056 539 B3 shows a further splash guard, which against the gravure cylinder itself, ie on the lateral surface, is employed.
  • the splash guard has for this purpose a spray panel, which has webs, so that the support surface can be reduced to the printing cylinder.
  • the DE 72 30 810 U1 discloses a multi-part splash guard. It has both a tubular jacket, which can be pushed over the rotating cylinder axis, as well as splash guards, which protrude beyond the rotating gravure cylinder and can catch drops of paint there. So that the splash guard is held in position, it is firmly connected to the machine frame, ie a side wall.
  • Object of the present invention is therefore to provide a gravure printing unit with a splash guard, both a better splash protection is guaranteed and easier handling of the splash guard is guaranteed.
  • the gravure printing unit according to the invention is used for printing a printing substrate in a printing press and has at least one printing cylinder, also referred to as a gravure printing cylinder, an inking device and an impression cylinder, also referred to as impression roller.
  • the pressure cylinder has at its two ends journals for supporting the printing cylinder, wherein in the region of a respective journal each a splash guard is mounted to prevent paint splashes, which arise due to the rotational movement of the printing cylinder and the journal.
  • the gravure printing unit has a mandrel with two clamping regions and a gravure sleeve tensioned on the printing cylinder, wherein the gravure sleeve is fixed at its ends in each case by a respective clamping region of the mandrel.
  • a respective splash guard associated clamping element on the mandrel is a respective splash guard associated clamping element, in particular a clamping sleeve, arranged to transmit a clamping force on the splash guard to press the splash guard against the Tiefyaksleeve and keep the splash guard in its working position.
  • the respective splash guard and the Tief umansleeve are rotatable relative to each other and thus rotatably mounted.
  • the splash guard while the gravure cylinder performs a rotational movement, the splash guard is stationary and does not rotate, so that no splashes of paint can be thrown off the splash guard. It is also advantageous if the splash guard is designed to be pushed onto a respective journal, since then no color drops can be thrown away from the journal.
  • the respective splashguard is releasably connected to a respective end of the intaglio sleeve so as to be able to remove or reuse the intaglio sleeve together with the two splashguards in the event of a required change of the intaglio sleeve.
  • the simple removal option of the splash guards thus a quick cleaning option is created.
  • a respective clamping element is positively connected to a respective splash guard and a respective clamping element is connected by means of at least one connecting element, in particular by screwing, with a bearing plate of the mandrel.
  • a respective splash guard is associated with a socket, wherein the sleeve can be pushed onto the mandrel and is rotationally connected to one end of the gravure sleeve and / or with the mandrel.
  • the bushing can be clamped by one of the clamping areas of the mandrel.
  • the splash guard is rotatably mounted on the bush and in particular has a rolling bearing, for example, a needle bearing, for mounting the splash guard on the socket.
  • a respective splash guard has an outer bush, wherein in particular the outer diameter of the outer bush corresponds approximately to the outer diameter of gravure sleeves commonly used.
  • a respective splash guard has a particularly absorbent fabric and a clamping device for clamping the fabric on a portion of the lateral surface of the Tiefyaksleeve.
  • a respective clamping device may for this purpose have two clamping arms, which are arranged rotationally fixed on the outer bush and braced against each other with a spring, wherein a clamping mechanism for clamping the tissue is connected to a respective clamping arm.
  • a respective splash guard has a particularly absorbent fabric and at least one retaining mandrel for holding the fabric on a portion of the lateral surface of Tief umansleeve, in particular, the position of the retaining mandrel is variable on the circumference of the outer sleeve.
  • the retaining mandrel has a corrugated lateral surface and in the tissue per retaining mandrel a corrugated lateral surface and in the tissue per a retaining pin each provided a hole, so that the tissue can be slipped with its holes on the at least one retaining mandrel.
  • the splash guard has a scraper engageable against the end face of the intaglio sleeve, for intaglio sleeves whose outer diameter is greater than the outer diameter of the outer sleeve.
  • the invention also relates to a narrow web press with at least one gravure printing unit as described above, in particular for printing folding boxes and labels.
  • Fig. 1 shows a section of the gravure printing unit 100 according to the invention with a Wegsleeve 2 a splash guard 4 and a mandrel 1. From the mandrel 1, which is mounted in a bearing in the machine frame, not shown bearing plate 1.1, both a splash guard 4 and one end of Tieftiksleeve. 2 held. Possible embodiments of the mandrel 1 are the Professional well known.
