Definitions
- the present invention relates to a printing cylinder for flexographic printing according to the preamble of claim 1.
- the printing cylinder comprises a cylinder body made of a carbon fiber composite material, which forms a self-supporting sleeve, which is supported at its ends by disks on a cylinder core.
- This sleeve carries the clichés that form the printing form and glued to the outer surface of the sleeve or clamped on it.
- a disadvantage of this construction are the abutting edges, which are formed at the places where the edges of the clichés are joined together on the sleeve. During the printing process, the abutting edges lead to disruptions in the concentricity of the printing cylinder, such as the so-called "bouncing", ie a sudden rebound during the start of the abutting edge on the adjoining cylinder.
- Object of the present invention is therefore to provide a printing cylinder of the type mentioned, which has optimal operating characteristics, but at the same time is relatively simple.
- the printing cylinder according to the invention comprises a jacket layer of a polymer which is formed integrally with the cylinder body.
- This cladding layer itself forms the printing form and can be treated for this purpose, for example by means of laser engraving or by a photopolymer process. If one chooses a material with advantageous rebound properties for the cladding layer, vibrations are cushioned during the rotation of the printing cylinder and the running properties are improved.
- adapter sleeves or the like can be completely dispensed with, so that the overall structure is substantially simplified.
- the pressure cylinder 10 shown in Figure 1 comprises a cylinder core 12 made of steel, which is provided at its two ends with upstanding on the end faces 14, 16 of the cylinder core 12 stub axles 18, which serve for storage in a machine frame.
- the printing cylinder 10 comprises a cylinder body 20 which is formed by a cylindrical sleeve made of a carbon fiber composite material, which surrounds the cylinder core 12 coaxially and is spaced therefrom.
- the carbon fiber composite material of the cylinder body 20 may be, for example, a skeleton of diagonal wound Carbon fibers, which are embedded in a matrix of plastic.
- the cylinder body 20 itself is also non-rotatably on its inner surface 22 and free of play connected to the discs 26, so that the cylinder core 12, discs 26 and cylinder body 20 form a rotationally connected unit.
- this structure is made EP 1 025 996 A1 known.
- the cladding layer 36 is made of a polymer and forms the printing forme of the printing cylinder 10.
- the outer circumferential surface 38 of the cladding layer 36 which here forms the outer surface of the printing cylinder 10 is suitably processed, for example by an engraving process such as laser engraving or by a photopolymer method in which a photopolymer forming the cladding layer 36 is exposed and the unexposed areas are chemically dissolved out.
- an engraving process for example rubber is also suitable as a material for forming the cladding layer 36.
- the material of the jacket layer 36 advantageously has a suitable rebound resilience, so that the jacket layer 36 absorbs and absorbs vibrations and shocks transmitted from an adjacent, adjacent to the AuJ3en Structure 38 of the printing cylinder 10 further roller can.
- the printing cylinder 10 according to the invention thus combines the advantages of a comparatively simple structure with good running characteristics. It is also possible, unlike the structure shown in Figure 1, for example, to use a solid cylinder body and to dispense with the inner structure shown in Figure 1 with a cylinder core 12 and discs 26 as a spacer.
- Figure 2 shows the cylinder body 20 with the coated thereon shell layer 36 in cross-section, omitting the internal construction of the printing cylinder 10, ie without cylinder core 12 and discs 26.
- intermediate layers may be arranged, as in cross section of the printing cylinder 40 is shown in Figure 3.
- the intermediate layer 42 shown there also consists of a polymer which, however, is softer than the polymer of the cladding layer 36. In this way, the running properties of the printing cylinder 10 can be further optimized.
- a thin protective layer 44 is applied, which protects the printing form of the cladding layer 36 from damage, but does not affect the surface shape and properties during printing.
- the cladding layer 36 and possibly other existing layers 42, 44 are removed from the cylinder body 20 by rotation, so that the peripheral surface 34 is exposed again and a new cladding layer 36 can be applied, the in the gravure or photopolymer method to a new printing form is processed.
