Definitions
- Expansion layer made of compressible material
- the invention relates to an expansion layer made of compressible material, which is arranged in a rotary printing form between a carrier core and a sleeve.
- Metallic cylinders are primarily used for gravure printing, and a functional profile is applied to their surface.
- Steel rollers are usually galvanically coated with a copper layer, which then bears the functional profile.
- Rotary printing formes are frequently used in flexographic printing, in which a sleeve is seated on a metallic roller core.
- the sleeves are often produced galvanically, for example as nickel sleeves, or consist of fiber-reinforced thermosetting materials.
- the functional profile is located on the outer surface of the sleeve.
- metallic cylinders with a technical surface are used, for example coatings made of polytetrafluoroethylene, which have an adhesive effect, metallic sleeves or hollow cylinders with a technical surface, and wound fiber-reinforced thermosetting sleeves with a technical surface.
- the technical sleeves like the sleeves for flexographic printing, can be pneumatically mounted on roller cores. They are also used as tubes or as semi-finished products for cylinder production.
- Sleeves are increasingly being manufactured with the help of thermoplastic pipes or hoses or from composite materials.
- the tubular semi-finished products are drawn onto or pushed onto a conical cylinder with the aid of heat. This is described in more detail in the not yet published DE 198 54 735.8.
- Non-conical production cylinders can also be used in the manufacture of the sleeve. After warming up the production cylinder, for example via a heat transfer liquid speed or via an upstream heating process, the tubular semi-finished product is pushed onto the production cylinder by means of a pressing-on direction. It is also possible to feed the semi-finished product directly from an extruder onto the manufacturing core.
- the manufacturing core is cooled, so that the thermoplastic material of the sleeve is consolidated.
- the tensile stresses frozen after consolidation can be adjusted so that the sleeve can remain on the manufacturing cylinder or can be removed from the mold. De-molding is done, for example, with the help of a scraper.
- the demolded sleeves can be placed on a corresponding carrier cylinder and also removed again. This can be done pneumatically or mechanically.
- the connection of the sleeve to the carrier core which consists, for example, of steel or plastic, can be produced by means of frictional engagement or positive engagement. With the frictional connection, the sleeve is manufactured on a manufacturing core that has a slightly smaller diameter than the later carrier core.
- the manufacturing core can also have the same dimensions, in which case the shrinkage stresses generated during production are used.
- the sleeve is manufactured on a manufacturing core which has geometric structures, for example grooves, which are molded into the sleeve.
- the carrier cores carry the complementary structure, so that the combination ensures the positive connection.
- the expansion layer also has the advantage that small bumps, for example on the inside of the tubular base body, do not have any effect on the sleeve, since they are compensated for by the expansion layer on the later carrier core. This eliminates the need for complex internal machining by honing and the like. In this way, otherwise critical semi-finished products such as extruded thermoplastic pipes or pipes made of fiber composite plastics made by pulltrusion can be used for the sleeve.
- the advantage remains that geometric structures are molded on the manufacturing cylinder during manufacture.
- the expansion layer thus stores on the one hand the force that is necessary for the frictional connection of the carrier cylinder and the sleeve and thus ensures the frictional connection between them. At the same time, a uniform distribution of the surface pressure is ensured.
- a functional profile is introduced into the sleeve after the manufacturing process. This can be done by direct structuring using a laser beam, by removal from the ionized state or by mechanical processing. In a second process, coatings made of polyurethane, polytetrafluoroethylene, copper and the like can also be applied, which are then available as a functional layer. Flexo clichés can be glued on directly. Depending on the later application, tubular base bodies of various materials and dimensions are used. The use of expansion layers makes it possible for the sleeve itself to have a thick wall, so that it can only be expanded slightly.
- the sleeve is used as a printing form in gravure printing, flexographic printing or in embossing. With the help of a laser, screen structures can also be introduced into the sleeve
- the functional layer can also be a wear protection layer, for example.
- Functional profile should also be understood to mean openings, bores and the like through the sleeve. It is also possible to subsequently provide the sleeve with perforations in the manner of a sieve. Such a sleeve can then be used, for example, as a rotary sieve for sieving bulk goods or as a suction cylinder, for example for sucking in films or for removing water from paper.
- depressions are arranged on the outer peripheral surface of the expansion layer or on its inner peripheral surface.
- the depressions can extend in the axial and / or radial direction on the expansion layer and can have a wide variety of shapes and cross sections. They can also be designed as holes which, for example, continue hole structures in the sleeve through the expansion layer.
- the depressions are at least partially designed as circumferential open ring channels.
- the ring channels can run parallel to each other.
- the ring channels are further preferably arranged equidistantly; if the bending compensation requires it differently, ring channel groups in which the ring channels are relatively close together are also possible.
- the depressions can at least partially be designed as channels for liquid or gaseous media, which are used, for example, for cooling or heating the sleeve.
- the channels can also be spray channels for paint or suction channels.
- the expansion layer preferably consists of an elastic material with a gaseous filling, for example a plastic foam or expanded polystyrene beads.
- the elastic material and / or the wear protection layer is provided with electrically conductive particles.
- Extended functions can thus be carried out with the newly designed expansion layer, whereby it is still arranged on the carrier core or on the inside of the sleeve and serves as an improved compensation layer that covers the contact line, for example between the sleeve and an impression in a flexographic printing machine. set up exactly.
- Figure 1 shows a carrier core with an applied expansion layer while sliding on a sleeve
- Figure 2 pushed the sleeve completely onto the carrier core.
- a cylindrical support core 2 is shown, on which an expansion layer 3 is located.
- This expansion layer is provided on its outer circumference with a plurality of depressions 4, which are designed here as open circumferential ring channels.
- the expansion layer 3 can have a wear protection layer on its outside, but this is not shown.
- a sleeve 1 is pushed onto the carrier core 2 and the expansion layer 3 from the left side of the drawing figure.
- a channel 5 formed by carrier core 2 and expansion layer 3 is provided, via which the sleeve 1 can be pressurized. This is generated, for example, by a gaseous medium.
- Figure 1 clearly shows that those areas of the expansion layer 3, which are already under the sleeve 1, are highly compressed, with part of the material of the expansion layer being displaced into the depressions 4.
- Figure 2 shows the fully wound sleeve.
