Definitions
- the present invention relates to a pressure cylinder for receiving an axially positionable and / or axially displaceable pressure sleeve according to the preamble of Claim 1.
- the present invention relates to a method for axial positioning and / or moving a printing sleeve on a printing cylinder according to the preamble of claim 14.
- Tubular or sleeve-shaped pressure sleeves e.g. Blankets for the Offset printing as described in US 5,215,013 are applied axially to a cylinder applied and removed from this.
- Blankets for the Offset printing as described in US 5,215,013 are applied axially to a cylinder applied and removed from this.
- a rubber blanket in that Described patent are usually openings or air holes on the Operator side of the blanket cylinder arranged to apply pressure to the inside of the Blanket to act on when the blanket is axially from the blanket cylinder removed or applied to it.
- Blankets can stick if they remain attached for too long because Air pressure from the air holes can be blocked and the drive side of the cylinder do not reach.
- the placement of holes is due to use difficult only a series of air holes on the operator side; it could also happen that the sleeve does not inflate or expand at all. Holes not placed correctly can cause air to simply escape from the operator side of the sleeve without the Inflate and expand the drive side of the sleeve.
- a single row of holes on the Operator can inflate only one of the blankets on operator side, so that other blankets closer to the drive side cannot be removed.
- a turning bar pressurized with compressed air which e.g. in the Folder superstructure of a rotary printing press can be used, known which are arranged adjacent on their peripheral surface in the axial direction Has air outlet openings from which blown air emerges and between the surface an air cushion to the turning bar and a paper web guided around the turning bar non-contact transport of the paper web builds up.
- the individual air outlet openings The turning bar are provided with valves, the valves having two switching states can take. In the first state in which the air outlet opening is not one The paper web is covered, blown air exits through a duct in the valve, while the valve itself closes the air outlet opening and thus a reinforced one Blowing air prevented.

- a printing sleeve which is pushed onto the printing cylinder or is removed from it, regardless of its current position on the impression cylinder always with the necessary amount of compressed air through the opening in the surface of the Pressurized pressure cylinder and thereby ensures that the pressure sleeve in necessary stretched, and a trouble-free and reduced friction Moving the pressure sleeve is advantageously possible.
- the printing cylinder according to the invention also has the advantage that the Flow restrictor vortex generated when the at least one opening at least is not partially covered by the pressure sleeve.
- the flow limiter has a plurality of Has slats.
- a flow limiter with a large number of fins is simple producible and insertable into the surface of the printing cylinder. This allows one simple construction of the flow limiter without moving parts using the Flow conditions inside the flow restrictor generating Fluid vortex can be caused.
- the ends can be one another opposite slats be spaced such that they have a free channel for the Form fluid flow.
- the flow limiter prevents flow Objects and / or textile material and / or fiber material includes.
- the flow restrictor can comprise a valve which, depending on the axial position of the pressure sleeve is open or at least largely closed.
- valves which like the above mentioned vortex generating flow limiter depending on the axial Position of the pressure sleeve limit the flow of fluid, in particular air.
- a device is also used when using valves to limit the flow provided which the displacement of a pressure sleeve without problems and allows for reduced friction in any position of the pressure sleeve. In advantageous Additional control devices and sensors can thus be dispensed with become.
- the at least one opening may comprise a plurality of openings which are in Circumferential direction offset on the outer surface of the cylinder body are.
- the plurality of openings is assigned to a pressure sleeve.
- the at least one opening has a plurality of Includes openings which are offset in the axial direction on the outer surface of the Cylinder body are arranged.

- the additional supply channel 42 can take place in the valve element 400 also formed as a bypass to the valve element 400 in the flow limiter 78 his.
- the flow restrictors can form a part with the cylinder or can be used as Insertion elements can be formed in the existing holes in a cylinder be pressed or screwed. This makes it easier to manufacture new ones Cylinders and also easier conversion or retrofitting of existing cylinders.
- the Flow restrictors can be made of plastic or a metal. flow of another form, e.g. slats 76 of square or triangular design in FIG. 4, can also be used.
- the present invention has particular advantages when used in a printing press with a variety of pressure cylinders powered by a single pressure source be used.
- the pressure from the pressure source can thus be on a sufficient level is maintained even if different blankets or other sleeves are removed. Even if several sleeves from different cylinders, e.g. even cylinders of different printing units are removed, there is no uncontrolled outflow of fluid.
