  • the sleeve is expanded in such a way that it extends to the Ink roller can be drawn up.
  • the invention is therefore based on the object of a printing press with a To create printing unit that has an inking roller on which a Blanket sleeve can be pushed on and removed quickly and with little effort.
  • the printing unit according to the invention in a printing press which comprises an inking roller and a forme cylinder, the inking roller being associated with a rubber blanket sleeve, is characterized in that the inking roller is overhung on a side wall of the printing press and the rubber blanket sleeve can be pushed axially onto and from the inking roller is removable. Due to the described configuration of the printing unit according to the invention, the rubber blanket sleeve assigned to the inking roller can advantageously be changed quickly and without great effort by the printer. For this purpose, the printing press only has to be stopped briefly in order to pull the rubber blanket sleeve to be changed axially from the inking roller, which can be carried out without problems on the side of the inking roller which is not supported.
  • the pulling and pushing the blanket sleeve onto the inking roller can, for. B. supported by the fact that the inking roller is pressurized with compressed air, which by z. B. exits in the surface of the inking roller existing openings and which expands the blanket sleeve when pulling or pushing and at the same time forms an air cushion under the sleeve on which the blanket sleeve is easily displaceable.
  • To change the blanket sleeve can advantageously in the inventive design of the printing unit on tools for expanding the inking roller, such as. B. Rolling rails, trolleys or indoor cranes can be omitted.
  • the drive of a driven inking roller according to the invention does not have to be released from the inking roller during the exchange of the rubber blanket sleeve.
  • a printing unit according to the invention also offers that over the prior art Advantage that the printing unit rollers can be arranged as desired in the printing unit, because the inking roller for removal from the printing unit for the printer not from the The circumferential side of the roller must be freely accessible.
  • the printing unit according to the invention is considerably faster Color change, e.g. B. from Coldset to heatset, possible because of this a new chemical Properties of the respective color adapted rubber blanket quickly and without large Workload can be drawn onto the inking roller.
  • the impression width remains even if the thermal conditions change during printing constant because a very thin rubber layer when using the rubber blanket sleeves can be used, the expansion of which only changes with thermal fluctuations changes slightly.
  • the diameter of the inking roller and the Diameter of the forme cylinder are essentially the same size, which in Short inking units, especially in anilox inking units, advantageously one stencil-free printing guaranteed.
  • the printing unit according to the invention can further comprise a transfer cylinder, it being advantageous to substantially equal the diameter of the transfer cylinder Adjust the diameter of the inking roller, which is also a stencil-free Pressure favors.
  • the diameter of the transfer cylinder can also be as a integer multiple of the diameter of the inking roller can be selected.
  • the transfer cylinder also be assigned a cylindrical, axially movable rubber blanket sleeve. Consequently will also change the blanket of the transfer cylinder for the printer considerably simplified and can now, as in the above-mentioned change of Rubber blanket of the inking roller carried out quickly and without a lot of work become.
  • the transfer cylinder can advantageously be flying on one Sidewall of the printing machine and be loaded with compressed air.
  • the inking roller can structurally correspond to the transfer cylinder, which makes it possible to have both a substantially same type of cylinder Ink roller and use as a transfer cylinder, which is advantageous in a reduction in the manufacturing costs of the printing press, as well as the logistics and Storage costs, precipitates.
  • the inking roller and the transfer cylinder structurally corresponding blanket sleeves are assigned, which z. B. only by a different layer structure of the rubber blanket sleeves can distinguish.
  • the inking roller and the Transfer cylinders are assigned identical blanket sleeves, making the printer advantageously only one type of blanket sleeve needs to be kept in stock, which if necessary, either on the inking roller or on the transfer cylinder can raise. This reduces the storage as well as the for the printer Logistics costs for the blanket sleeves. When using it constructively corresponding or identical blanket sleeves also reduce the cost of that Wash the blanket sleeves because there is only one sleeve washing device for everyone Blanket sleeves is necessary.
  • those assigned to the inking roller Blanket sleeves and the blanket sleeves assigned to the transfer cylinder are interchangeable, so that blanket sleeves that have not yet worn out are, but only for washing the inking roller and the transfer cylinder were removed, after washing again on the inking roller or Transfer cylinders can be pushed on without going to the previous one Assignment of the two blanket sleeves must be observed.
  • the printing unit can be several Rider rolls or just a single rider roll, each of which Ink roller or the forme cylinder are assigned and each of the Ink roller or the forme cylinder can be switched off and on again.
  • the printing unit continues to be an anilox roller or includes other depressions roller, with the metering of the printing ink on the inking roller.
  • a printing unit To equip printing press additionally with a side wall, which with an opening is provided, through which the blanket sleeve axially on the inking roller can be pushed on and pulled off.
  • the opening in the side wall which is located on the Location of the side wall is located on an imaginary extension of the axis of the Ink roller touches the side wall and is large enough to hold the Moving the blanket sleeve through the opening can, for. B. with a swiveling or stored storage.
  • This can be the storage of the inking roller Support during the printing process of the printing press and when the press is at a standstill Printing machine can be swung from the inking roller or parked and thus uncover the opening in the side wall.
