Definitions

  • the present invention relates to replaceable printing technologies in a printing unit of a machine for printing webs of material, preferably endless webs of material.
  • the present invention relates to a printing unit which can alternate between off-set printing and flexo printing, in which the two printing technologies not only share the same web transport (printing roller) (pos. 1) but also share 2 "shafts" (pos. 2 and 3) which are prepared to be fitted with a sleeve (pos. 4 and 5). In cases of offset printing, these "shafts” act as plate roller (pos. 6) and rubber cloth roller (pos. 7), while in cases of flexo printing they act as raster roller (pos. 4) and cliche roller (pos. 5).
  • Figure 1 schematically shows a preferred embodiment of the printing unit in accordance with the present invention, configured as a flexo printing unit
  • Figure 2 schematically shows a preferred embodiment of the printing unit in accordance with the present invention, configured as an offset printing unit.
  • Figure 1 shows the parts in question configured as a flexo printing unit.
  • the web material (10) is supported by the printing roller (1), which in the shown is fixedly mounted in the printing unit.
  • the flexo unit's raster roller (4) is a removable sleeve which is applied to a fixedly mounted shaft (2) in the printing unit.
  • the shaft (2) is suspended in such a manner that it may be displaced parallelly (8) in a horizontal plane.
  • the flexo unit's cliche roller (5) is also a removable sleeve, which is applied to a fixedly mounted shaft (3) in the printing unit.
  • the shaft (3) is suspended in such a manner that it may be displaced parallelly (9) in a vertical plane.
  • the preferred system to provide colour to the raster roller is by a doctor blade. In order for the invention to be more clearly understood, the system is not shown in the figure.
  • Figure 2 shows the arrangement configured as an offset printing unit.
  • the raster roller (4) is replaced by the printing unit's offset plate roller (6), which is also a removable sleeve that has been applied to the fixedly mounted shaft (2) of the printing unit.
  • the flexo unit's cliche roller (5) is replaced by the printing unit's offset rubber cloth roller (7), which is also a removable sleeve that is applied to the fixedly mounted shaft (3) in the printing unit.
  • the system that provides moisture and/or colour to the plate roller of the offset printing unit is not shown in the figure.
  • the sleeve which is compressible on the inside, is pushed along the shaft, which is provided with channels to an inner chamber which is provided with pressurized air forming a layer of air, whereupon the sleeve may be displaced. After the sleeve has been mounted, the supply of pressurized air is stopped, which causes the inner side of the sleeve to contract, and the sleeve is retained on the shaft.
