Definitions
- the invention relates to a method for producing round, metallic Sleeves as coating carriers, on which function-specific, below multilayer layers can be applied, for example compressible Layers for offset printing.
- DE 41 40 768 C2 which is regarded as the closest prior art with regard to the cylindrical sleeve according to claim 24, discloses a method for producing an offset printing form a metallic material for a forme cylinder of a printing press.
- the plate-shaped blank is opened for printing plate production conventional type coated and exposed, after which the rectangular plate in a welding device by bending into a Bring hollow cylinder shape and clamped there in register.
- the one on top of the other facing edges of the plate are longitudinally welded together, whereby the welding process is carried out in such a way that a weld seam is created which Underside has a concave shape.
- the resulting printing form on the Forme cylinders are coated and exposed.
- a disadvantage of this manufacturing process is the fact that the length is stretched of the plate-shaped blank, which will later give the diameter, exactly parallel and with a correspondingly high accuracy of significantly better than 1/10 mm tailor. It also causes the introduction of heat when welding a longitudinal distortion of the material in the weld area. This elongation leads to a ripple on both sides along the weld. When using a sleeve produced in this way leads to the inevitable waviness in the seam area to the fact that air pockets occur, which are under external pressure on the sleeve this migrate, which causes the sleeve to twist on the cylinder.
- DE 39 08 999 C2 discloses a cylinder body and a method for coating of the cylindrical body. It is proposed to make a cylindrical body like this to provide with a seamless coating that as a coating material thixotropic multi-component material in the form of a propellant and inhibitor staggered, flowing foam with rotation and feed on the cylindrical body is applied approximately in a spiral.
- a coating material thixotropic multi-component material in the form of a propellant and inhibitor staggered, flowing foam with rotation and feed on the cylindrical body is applied approximately in a spiral.
- metallic aluminum or a carbon fiber reinforced plastic is used.
- plastic sleeves also has disadvantages. For example in view of the considerably lower modulus of elasticity, these have to be increased Wall thickness are made to be comparable to metallic sleeves Achieve seat strength. High wall thicknesses in turn, for example the application of heat-treated functional layers higher Exposed to temperature are sensitive to temperature, resulting in loss of Dimensional accuracy and build up high internal stresses.
- EP 0 421 145 A2 and EP 0 715 966 A1 are sleeve-shaped rubber blankets become known, which laterally on blanket cylinders from Have rotary printing presses installed.
- the rubber coating is on Nickel sleeves applied.
- the nickel sleeves are electroplated manufactured.
- a mother cylinder is inserted into the nickel bath a thin nickel skin, which later after reaching the required wall thickness is rolled from the master cylinder.
- the nickel sleeve production in this way has an increased power requirement and is extremely time consuming.
- US-PS 54 80 505 is a method for the production of wound metal tubes described.
- the tubes produced afterwards are, however, because of the resulting ones Not to use circumferential grooves as carrier sleeves for blankets in offset printing.
- the object of the invention based on a manufacturing process for sleeves as cylindrical coating substrates to provide, which avoids the disadvantages of the known solutions.
- sleeves as Coating carriers as economically as various types of sleeves in large quantities have long been produced, such as cardboard tubes, which be wrapped from layers of paper or plastic sleeves, also from Tape material wrapped.
- core material is primarily used as a strip material metallic tape into consideration.
- the solution according to the invention also permits integrated pretreatment of the Coil material provided in spool form, including the actual processing upstream operations.
- the strip material can be swiveled into storage be attached and the necessary cleaning and conditioning of the belt takes place during the processing of the tape material.
- the generation of a Preload in the strip material allows a high precision of the Rewinding process with the most precise joint formation.
- the pendulum of the Storage of the strip material allows a winding angle specification to be dispensed with - Rather, it sets itself up automatically.
- the strip material After the strip material has been cleaned, it is dried in one Drying station.
- the strip material can then be conditioned.
- Conditioning in this context is a surface treatment of the strip material is meant, for example a surface treatment with a primer.
- a primer for example Surface adhesion of the adhesive to the tape material with simultaneous tape cleaning be improved.
- a further improvement in the adhesive bond can instead of the primer, by enriching the surface of the strip material with Non-ferrous ions, such as copper ions. These enrichments are missing in high-alloy steels and stainless steels. They don't just improve that Hardening of anaerobic adhesive systems considerably, but above all that Metal adhesive connection.
- An ion enrichment of the strip material can be caused by Brush the tape material with copper or brass brushes; also a A primer application for copper ion enrichment would be conceivable.
- one side of the strip material is treated after the treatment a deflection of the strip material, so that the remaining side can be cleaned and pretreated.
- appropriate Cleaning station, drying and pretreatment also for this side of the Band material provided.
- the supporting surface of the winding cylinder associated with trimming devices can For example, be cutting tools such as milling cutters or as optical devices such as lasers. Are lasers as edging devices provided, the edge of the layers can be trimmed and all around at the same time be welded.
- the tensioning of the strip material is maintained by an im Conveying path of the belt material arranged pull and brake roller around which the Tape material is looped over a relatively large circumferential area. On a The side of such a type of pre-tensioned tape material is then applied, for example an anaerobic adhesive system.
- An apparatus for performing the method according to the invention provides that Housing or support wall for the pretreatment stations, the storage of the Material spool, the pull and brake roller and the adhesive application station relative to To design winding cylinder pendulum, so that by the feed and the Winding speed results in a self-adjustment of the winding angle.
- FIG. 1 is an illustration of a winding station which is only schematically outlined here.
- the winding station 1 comprises a winding cylinder 5, on both sides in two Tailstocks 3, 4 is rotatably mounted. Below the winding cylinder 5 is in this Top view of the machine frame 2, on which a material spool 7, which feeds a narrow strip material 6, is arranged to be movable. It is recognizable that the material spool 7, which is pivoted, in a winding angle to Winding cylinder 5 is aligned. This alignment takes place automatically by default of the winding angle during the feed of the material spool 7 in the direction of the arrow. During the winding process, a first one forms on the winding cylinder 5 Layer 29 of strip material 6, which at joints 30 without joints and butts together without overlap.
- the end faces of the winding cylinder 5 are Devices 9,10 assigned to the edge trimming of the winding layers. It can are milling devices or optical devices such as lasers, with the help of the end-side end areas of the core layers to be wound are edged. When using lasers on the end faces could for example, the resulting tape tip can be fixed. In addition to the fixation The tape outlet tip can also be trimmed simultaneously with the lasers of the entire edge and its all-round welding. In order to can the end faces of the single or multi-layer sleeve made of tape material stiffened and better secured against accidental damage.
- a stepper motor 36 may be attached, with the help of which Tape material 6 is held under tension.
- the winding cylinder 5 rotates in Winding direction 11 and winds the narrow contained on the material spool 7 Tape material 6 constantly from this. It should also be mentioned that on the Machine frame 2 guides 15 are available, in which the winding Strip material stock 7 during the feed when winding parallel to the axis of the Winding cylinder 5 is carried.
- FIG. 2 shows a winding station for carrying out the method according to the invention, in which the pre-treatment of the strip material to be wound is already taking place can.
- the winding station 1 comprises a support wall 16 in which, among other things, a Material spool 7 is rotatably mounted, the supply of narrow strip material 6th receives.
- the narrow strip material 6 becomes constant from the supply reel 7 processed, and runs after a first redirection to a Material cleaning station 18 on.
- the strip material 6 is cleaned there.
- the Cleaning of the strip material 6 is necessary to keep dust, grease or other Remove deposits from the surface of the slowly unwinding belt 6.
- This cleaning station 18 initially only acts on one side of the strip material 6 a, which then passes through a first drying station 19, from which the Strip material 6 reaches a primer station 20.
- all pretreatment stations are such as cleaning, drying and conditioning for the top and bottom of the Tape material 6 taken from the support wall, which is relative to the supporting Surface of the winding cylinder 5 is pivoted. From set The winding speed and the feed of the support turns up Winding angle ⁇ automatically without pre-settings being necessary. More precisely, arises due to the tension in the belt - caused by the tension and Brake roller 24 - and the feed and the speed of the winding angle ⁇ a. This requires a precise coordination of speed and feed, which but can be calculated with high accuracy. When using a high resolving stepper motor 36 with encoder this is not a problem Pendulum 17 of the support wall is given by the suspensions.
- the band material 6 cleaned and conditioned on its underside is on the Deflection 37 turned by about 180 °, so that the remaining side of the Belt material is accessible for cleaning and pretreatment.
- the Cleaning station 18 can also be designed so that by polarization and Etching the surface of the strip material 6 a micro roughness of the surface is brought about later on after applying an anaerobic adhesive to the Glue station 22 to achieve an improved adhesive effect. After Cleaning station 18 passes the strip material 6 on both sides of the Belt material 6 acting drying station 21, to which there is another Pretreatment station 20 connects, their function already above was written.
- the strip material 6 then passes through a drying station 19 and is now Conditioned on both sides for winding. Which are in the path of the tape material 6 subsequent traction and brake roller 24 is wrapped at about 270 °, whereby immediately before applying the adhesive at 22 the tape material 6 under Bias is maintained.
- the adhesive is applied in the adhesive station 22 pre-tensioned strip material 6 before it is wound up.
- a tape separator and Clamping station 23 is also provided in order to pre-tension the strip material 6 maintain.
- the tape material 6 is to be clamped temporarily after a one or multilayer sleeve on the supporting surface 5 is completed or is finished by means of the edging device 9, 10.
- Fig. 3 shows a material coil
- a stock of narrow strip material 6 - an extremely thin rolled steel, or Stainless steel sheet - is wound into a coil 7.
- the strip material 6 has one Material width 8 between 10 and 100 mm, its thickness 25 is about 0.05 mm.
- the coil 7 is rotatable about its axis 26 and is only shown schematically here.
- Fig. 4 shows a basic winding from a first winding layer.
- the narrow strip material 6 is wound around a winding cylinder 5 such that a first layer 29 is formed on the outer surface of the winding cylinder 5.
- the narrow strip material 6 is inclined by the winding angle ⁇ , so that the individual windings of the first layer 29 without the formation of joints and lie against each other without overlap.
- the edges 27, 28 of the narrow Tape material 6 form joints 30 of the first layer 29, at which they meet bump.
- the first layer 29 produced by means of the method according to the invention is accordingly oriented slightly diagonally on the winding cylinder 5 and extends over the entire width of the winding cylinder 5.
- the resulting per winding revolution Sleeve strip forms with the previous one already wound Sleeve strips butt joints 30. The exact formation of these butt joints without Joint formation and without material overlap is for the usability of the wrapped sleeves vital.
- Fig. 5 shows the representation of a winding sequence with multi-layer winding.
- the first layer 29 of the narrow strip material 6, which is the base layer of the Forms base sleeve is perpendicular to the first winding angle ⁇ in the winding direction 11 Normals 31 applied to the winding cylinder axis.
- the edges 27, 28 each form the said joints 30.
- Has the narrow strip material 6 according to the The method according to the invention previously passes through an adhesive station 22 at which a Adhesive was applied, so there can be another layer provided with adhesive on one side of the narrow band material 6 are applied to the first layer 29. It forms on the first layer 29 there is the further layer 32. As can be seen in FIG. 5 the winding of the further layer 32 with one for winding the first layer 29 opposite slope 35 takes place.
- joints 33 trained which are also designed without joints and without overlapping.
- the Butt joints 33 cross the butt joints 30 of the previously applied layer 29 and thus contribute to an increase in the rigidity of a multilayer sleeve composite.
- a band 6 of the same width is used layer 29 already underneath offset by half of the strip material 6 wound.
- the first layer 29 is formed with joints 30 Winding angle ⁇ wound on the winding cylinder 5, then the other Layer 32 wound so that it by half the width of the tape material 6 the first layer 29 comes up. Consequently, they are in such a winding resulting joints 33 not over the joints 30 of the first layer 29, but offset by half of the narrow strip material 6. This leaves a much higher buckling stiffness of multilayer sleeves.
