Definitions

  • the invention relates to a printing press with a device for detecting the presence of a printing form according to the preamble of claim 1 and a method for applying an order form according to the preamble of claim 10.
  • the printing plates intended for printing are positioned in the automatic plate changing machines and after a printed printing plate has been removed, they are fed to the cylinder that carries the printing plate during the printing process.
  • a clamping unit receiving and fixing the front edge of the printing plate and a clamping/clamping unit receiving and fixing the rear edge of the printing plate and subsequently clamping the printing plate are provided.
  • Alignment pins arranged at a distance from one another and corresponding to alignment punchings provided in the front edge of the printing plate are assigned to the clamping unit.
  • the clamping unit and the clamping/clamping unit are open and the printing plate is positioned with the fitting punches on the fitting pins.
  • the cylinder is turned in the opposite direction to the printing direction and the trailing edge of the printing plate is brought to the clamping/clamping unit, with means being provided which bring the printing plate closer to the jacket of the cylinder and position the free trailing edge of the printing plate in the clamping/clamping unit.
  • the clamping/clamping unit is then closed and clamped on the cylinder by moving the pressure plate in the circumferential direction.
  • the holding device has a front and a rear fastening device, with pneumatic means in particular often being arranged for clamping the application form.
  • Application forms and/or printing forms and/or printing plates are used in various printing methods, such as planographic printing or relief printing, in particular flexographic printing, or gravure printing.
  • the printing form and/or the flexographic application form has a number of raised areas.
  • Flexo application forms usually consist of a flexible base body, for example a polymer film, which has a thickness of between 0.2 mm and 1 mm, for example.
  • a strip is preferably arranged in each case, which consists, for example, of a plastic material. This serves to attach the application form in appropriate attachment devices.
  • a covering is preferably applied to the base body at corresponding points, for example a rubber covering.
  • a layer and/or a coating is removed so that a relief is created.
  • the carrier material in such forms of application is, for example, a plastic.
