Definitions

  • the invention relates to a blanket with a metal or plastic carrier plate consisting of several layers, in particular for covering a transfer cylinder an offset printing machine.
  • blankets which consist of a multi-layered Layer structure exist. These layers comprise a cover layer which is dyeable is and for transmitting a printed image with a print carrier, i. one Paper web is in contact. Furthermore, compressible layers and not stretchable layers used.
  • the compressible layers are Materials with air pockets and in the non-stretchable layers usually around tissue or tissue layers. It is beneficial below the printing topcoat to arrange a non-stretchable layer and below the non-stretchable Layer a compressible layer. However, other layer sequences can also be used and there can also be several compressible and non-stretchable layers be used.
  • the short metal back rubber blankets are called, but not from the rubber layer structure covered ends introduced into the cylinder channel, there is a risk that due to the Forces in the channel area during the printing process become individual Release layers from the carrier plate. In particular, there is a risk that the replaces the printing topcoat.
  • a printing blanket at the rubber layer also consists of several layers, at least one End of the blanket is sealed.
  • the sealant extends over the total height the material thickness of the rubber layer construction and also covers as a result of his approximately triangular cross-section partially the free ends of the cylinder pit to be introduced metal layer or carrier plate.
  • This arrangement is particularly Prevents liquids from entering the fabric during printing penetrate or cause a release of this layer below the uppermost layer. Extreme stress can damage the sealer or due to very high forces on the blanket ends the detachment of individual Layers the life of such blankets compared to the conventional Significantly shorten blankets without a rigid backing.
  • Fig. 1 shows a blanket with a resilient rigid support plate.
  • a metal is used, i. this carrier plate can be a conventional sheet metal plate, hereinafter referred to by the numeral 1 becomes.
  • a compressible layer 2 is arranged above the carrier plate and above the compressible layer 2, a non-stretchable layer is used which may consist of individual threads or of a fabric layer 3, the one non-stretchable insert offers.
  • a cover layer i.e. the printing layer of the blanket 10, which in contact with a not illustrated print carrier for the purpose of transmitting the printed image is.
  • a further fabric insert or fabric layer 5 is used, whereby the expansion behavior of the Layer structure can be optimized.
  • blankets can be used with a backing plate, the one have different layer structure, i. the compared to the representation of FIG. 1 may have other layer sequences and also the number of used Layers can be larger or smaller according to the respective application be as shown in Fig. 1.
  • the blanket 10 is shown with its support plate in an angled form, for fixing the ends of the blanket on a not shown Blanket cylinder (offset cylinder) yields.
  • Blanket cylinder offset cylinder
  • FIG. 3 A particularly advantageous and preferred embodiment within the scope of the invention is shown in Fig. 3.
  • the basic layer structure of the blanket 10 in Fig. 3 is not differs from the layer structure of the blankets 10 shown in FIGS. 1 and 2.
  • the significant difference according to the invention is that in the Layer structure according to FIG. 3, only the cover layer 4 and below the cover layer arranged fabric layer 3 almost to the end of the support plate. 1 extends, while the compressible layers 2 and shown in Figs. 1 and 2 Cover layers 5 extend only to the region of the fold.
  • this end is the so-called leading end of the blanket, which is known to be the most critical is what concerns the damage of the blanket layer construction.
  • the second end i. the so-called trailing end be formed according to the invention and in this form together with the leading End are fixed in the cylinder pit.
  • the channel width a transfer cylinder can be significantly reduced in comparison to an embodiment of FIG. 1, in which a larger channel width required is.
  • the channel width can have the smallest width if a blanket used according to FIG. 3 and only one end of the blanket gem.
  • Fig. 3 is formed, wherein preferably the leading end of the blanket for this purpose is used and the other, i. the trailing end, for example according to Fig. 1 is formed.
  • the cover layer may be made of rubber or polyurethane or similar materials consist.
  • the fabric layer may alternatively be made of hard rubber or polyurethane and consist of comparable materials.
  • the compressible layer can be made of rubber, polyurethane or comparable materials.
  • the carrier layer may be metallic or non-metallic materials.
  • the coating can be off a PET film comparable films, rubber coating, polyurethane, paint or similar Materials exist.
