Definitions

  • the invention relates to a sleeve arrangement for a printing cylinder, consisting of a fixable on a printing cylinder, rigid inner sleeve and one axially on the inner sleeve slide-on thin-walled printing form sleeve with the printing Surface.
  • printing forms or printing plates are used mounted on the steel printing cylinders of printing machines.
  • the printing surfaces of the printing blocks are special with so-called flexographic printing, they are generally frustoconical Printing dots are present, which are characterized by the process during printing widening the occurring forces elastically (so-called "dot gain").
  • dot gain the forces elastically
  • the Printing clichés not directly attached to the printing cylinders, it becomes an elastic or compressible intermediate layer provided that become elastic during the printing process deformed and thus the dot gain, which leads to loss of quality of pressure would decrease.
  • a Printing form which is produced by means of a printing plate, follows. On a rigid plastic support sleeve or metal becomes a double-sided, compressible Foam tape applied, on which the pressure plate is fixed. The assembly of the printing form thus produced on the printing cylinder takes place either directly or via an intermediary Adapter sleeve using a compressed air from the Air cushion built up inside the pressure cylinder.
  • DE 695 08 184 describes a sleeve arrangement for one Printing cylinder disclosed, which consists of a rigid inner sleeve (Intermediate sleeve 12) and one axially slidable onto the inner sleeve thin-walled printing form sleeve (thin jacket 14) with the printing surface (18).
  • This arrangement so in particular the arrangement of the intermediate sleeves should Serve purpose, a reduced supply of metallic Keep support cylinders in stock.
  • This prior arrangement consists of two matching rigid sleeves, the outer jacket forming a unit with the printing block.
  • EP-A-0 313 511 discloses a sleeve assembly which does the same
  • the preamble of claim 1 corresponds to a rigid Inner sleeve with a four-layer structure is disclosed on the a thin-walled printing form sleeve (printing plate) is pushed on is.
  • EP-A-0 727 326 and EP-A-0 452 disclose 184 one-piece printing sleeves, which on a printing cylinder be put on the outside Printing block is attached.
  • the cliché is firmer Part of the sleeve.
  • the printing sleeve is fixed with a cliché with the one underneath provided layer connected.
  • the cliché also firmly with the one below Layer connected.
  • the object of the invention is based on the prior art based on the production, storage and replacement costs to reduce in printing form production.
  • the main advantages of the invention can be seen in that the printing form produced according to the invention due to the very small wall thickness requires less material, which reduces the manufacturing costs. Because of the flexibility the film-like support sleeve, it is possible to conventionally provided between the support sleeve and printing plate to dispense with compressible foam layer, which makes the with the production of this foam layer very considerable work can be omitted.
  • the compressibility of the overall system is inventively effected in that on the below the adapter sleeve provided the compressible Layer is firmly in place and due to the flexibility the film sleeve acts through it.
  • the invention makes it possible for a Number of foam adapter sleeves with different parameters (Diameter, elasticity and thickness of the compressible Layer) are kept in stock and only those without compressible Layer-made printing form must be mounted.
  • the combination of features according to the invention advantageously achieves a material saving in that the avoidance the compressible layer required for the dot gain Part of the molded part is (such as in of DE 695 08 184 cited above is the case) and therefore the elastic covering is part of the reusable inner sleeve. Due to the extreme flexibility of the film sleeve, the Compressibility of the intermediate layer on the printing surface transfer.
  • the actual printing form is at Invention only from the flexible film sleeve with the attached printing surface (cliché), whereby due to the high flexibility (the extremely thin walls) the printing form sleeve is very strongly deformable and thereby for Storage can be compressed like an elypse. hereby do not arise in this compared to the conventional Scope deformable sleeve assemblies significant storage advantages (less space, less weight).
  • the high flexibility also enables a simplified Transport of the printing form sleeves according to the invention, since smaller Packaging can be chosen.
  • a printing form sleeve which consists of a film sleeve 12 , an adhesive layer 14 applied thereon and a printing block 16 .
  • the film sleeve 12 has a wall thickness of at most 0.5 mm, preferably between 0.15 mm and 0.35 mm and particularly preferably between 0.25 mm and 0.30 mm. It is preferably made of a plastic, but could also be made of metal or other materials, provided that it is only sufficiently flexible, ie has a sufficiently low rigidity. Polyesters are particularly suitable as the sleeve material.
  • the film sleeve 12 can be provided on the outside with axial micro-grooves 18 for the removal of air between the film sleeve and the printing plate in the production of the printing form using photopolymer films. These micro grooves 18 are only indicated in a small area in FIG. 1, they are actually provided on the entire outside of the film sleeve 12 .
  • the foam adapter sleeve 20 shown in FIG. 2 is axially pushed onto a pressure cylinder, not shown, with air outlet holes on the outer surface, forming an air cushion between the pressure cylinder and foam adapter sleeve 20 .
  • the foam adapter sleeve 20 comprises a supporting layer 22 , on the outside of which a compressible layer 24 is applied.
  • the supporting layer 22 is usually made of plastic and has a thickness of 3 to 70 mm.
  • the elastic layer 24 firmly attached to the supporting layer 22 is preferably a foam layer, especially consisting of PU foam, and has a thickness of 0.5 mm to 3 mm.
  • the foam adapter sleeve 20 has through bores 26 which lead from the inside of the load-bearing layer 22 through the elastic layer 24 and ensure that compressed air from the inside of the pressure cylinder can get to the outside of the foam adapter sleeve 20 when pushed onto the (not shown) pressure cylinder ,
  • the printing form sleeve 10 is then axially slid on using an air cushion that forms between the elastic layer 24 of the intermediate sleeve 20 and the film sleeve 12 .
  • the printing form sleeve is then aligned and the air supply is shut off, which completes the assembly of the printing form sleeve 10 .
  • the printing cliché can change over the thin and flexible film sleeve elastic on the compressible Support layer of the foam adapter sleeve, creating a high print quality is ensured.
  • After finishing the Printing process can remove the printing form sleeve and can be stored temporarily without great effort.
