  • the washing roller is set in an angular position of the cylinder where the beveled end of the Pressure plate opposite the washing roller.
  • a forme cylinder acts together with an impression cylinder.
  • the washing device for example with the washing roller also in the area of the incoming Gap arranged between the forme cylinder and impression cylinder.
  • the washing device can be pivoted by a corresponding Storage now both cleaning the cylinder surface of the impression cylinder as well as cleaning one on the forme cylinder serve stretched blanket cylinder.
  • To open a new one Blanket or other printing form on the forme cylinder is now attached to the cylinder with one end after the printing form the washing roller was turned on the cylinder while it was rotating.
  • the washing roller also takes on the function of an otherwise pressure roller to be provided.
  • washing roller for winding according to the invention of printing formes can in particular rollers with a soft rubber or Fleece cover but also brushes are used.
  • a printing form is used either to drive the washing roller decoupled by a coupling to be provided or otherwise Torque-free, so that the washing roller largely smooth due to the frictional force exerted by the printing form can turn.
  • washing roller When Winding up the printing form against the direction of winding up to drive, so that this creates an additional pulling force.
  • a washer roller for mounting printing forms is particularly advantageous if, for example, Nyloflex sheets with a printing surface like a flexo cliché should be.
  • the compliance of the washing roller cover gives thereby adapting to the different thickness of the printing form according to the printing and non-printing points. Regardless of the subject distribution with such a printing form this results in a pressure that is uniform over the width of the format the printing form on the forme cylinder.
  • FIG. 1 to 3 show what is referred to as a plate cylinder Forme cylinder 1 and the blanket cylinder 2 of a printing unit a sheetfed offset press.
  • the direction of rotation of these cylinders while printing is indicated by the arrows.
  • a washing device 3 in the Inlet area between forme cylinder 1 and blanket cylinder 2 is a known washing device 3 with a washing roller 4th appropriate.
  • the washing roller 4 extends over the format width of form and blanket cylinders 1, 2.
  • the washing device 3 is parallel through a pivot axis 6 runs to the axis of the washing roller 4, pivotable so that the Washing roller 4 both the blanket cylinder 2 and the forme cylinder 1 can be compared.
  • the washing device is pivoted clockwise, it lies the washing roller 4 on the blanket of the blanket cylinder and it the blanket is washed in a manner known per se according to the structure and function of the washing device 3 (Fig. 2). 3, the washing device 3 is here against the Has been pivoted clockwise, so that now the washing roller 4 on The circumference of the forme cylinder 1 is present.
  • the washing device 3 was used as an offset printing plate trained printing form 5 in a corresponding Clamping rail attached and the forme cylinder 1 in the direction of rotation Printing driven. It can be provided that the Washer roller 4 is placed on the forme cylinder exactly when the printing start of the forme cylinder 1 of the washing roller 4 approximately opposite.
