Definitions

  • the invention relates to a blanket with a rigid elastic support plate on which at least one elastic layer with a dyeable surface is arranged, of which a printed image is transferable to a printing material web, wherein the two ends of the Carrier plate are not covered by the elastic layer and the two ends of the elastic layer are covered by a sealer.
  • WO 01/70512 A1 discloses a blanket in which the flexible layers, i.e. the rubber layers with corresponding reinforcements of textile, one Covering layer - ie a printing layer and usually a compressible Layer are arranged on a rigid flexible support. Usually it is in this carrier to a metal plate. For cost reasons is often a Used steel plate on which the rubber layer structure fixed, i. usually glued on is. As stated, this construction consists at least of a cover layer whose Surface receives the printed image, for example, of an elastomeric material can exist. It is an advantage, but not mandatory, below the cover layer to provide a fabric insert. Usually, below the Tissue layer uses a layer of a compressible material, the air pockets may contain.
  • This layer structure can be achieved by a bonding agent on the Support plate are fixed, with the leading and the trailing end of the Plate is not covered by the rubber layer structure, so only the thin ones Steel sheets must be inserted into the cylinder channel and fixed there. Thereby There is a significant reduction in the channel width, which is known to be essential Has advantages.
  • WO 01/70512 A1 are thus the Ends the rubber layer above the cylinder channel opposite.
  • a blanket is already known in which the rubber layer, like the printing blanket described above also has a layer structure consists of several layers, which is sealed at the two ends of the blanket.
  • the sealant extends over the total height of the material thickness of the blanket layer structure and also covered by its approximately triangular cross-section partially the free ends of the metal layer to be inserted into the cylinder pit, i. the sheet metal plate.
  • the thickness of the sealant in the form of an elastomeric pad to increase continuously in the direction of the metal plate, so that a significant large area of the elastomeric pad over the rubber plate or over one on the Rubber plate used adhesion promoter layer is formed. This should in particular Tangential forces are counteracted, especially at the base of the blanket, i.e. arise in the transition region of the elastomeric support or the sealer.
  • the aforementioned known metal rubber blankets have the disadvantage that their life significantly below the life of conventional blankets without metal plate, although the above-described seal from the blanket surface until the steel sheet provides a complete seal.
  • FIG. 1 shows schematically the basic structure of a known metal rubber blanket. with regard to the layer structure also in the metal rubber cloths according to the invention can be applied, but is also a different layer structure with a greater or lesser number of individual layers within the scope of the invention applicable.
  • the metal rubber blanket 1 according to FIG. 1 comprises at least one cover layer 2 which supports the printing layer, because their surface is colorable with the printed image, so that of this surface on a substrate, not shown, the printed images are transferable.
  • On the lower side of the metal blanket 1 is a metal plate 3rd indicated, wherein only the right portion of the metal blanket 1 can be seen.
  • the plate end 4 of the metal plate 3, which may preferably be a steel plate, is not provided with the rubber layer and can thus together with the not shown fixed second end of the metal plate 3 in the clamping channel of a blanket cylinder become.
  • the metal plate 3 is a multilayer Layer structure provided. This can, for example, in addition to the printing overlay
  • FIG. 2 shows a non-stretchable layer, for example a fabric layer 8, a compressible layer.
  • FIG Layer 9 with air inclusions and an adhesive layer, for example an adhesive 10 include.
  • Figure 1 reveals that the sealer 5 in known blankets in particular is very thin in the upper part of the multi-layered construction. This is especially true in the Area of the end of the cover layer 2. This causes the problems described above, i.e. there is a risk that especially the cover layer 2 from the underlying Layers can solve or may exist in a partial solution the risk of penetration of dampening solution or the like.
  • the sealer geometry in that a Enlargement of the adhesive surface to the blanket is achieved while minimizing the tension in the sealer.
  • this can be achieved by an enlarged adhesive surface of the sealer 5, especially on the cover layer 2, which is not shown in detail in the figures.
  • the roughening occurs in the Comparison to a smooth, i. not roughened layer, such as through a section is produced, a much larger adhesive surface or adhesive surface geometry. This already causes an improved adhesion of the sealer especially on the Cover layer, whereby the problems described are avoidable, i. especially the life of the metal blanket can be increased.
  • FIGS. 3 a - f various forms of the design of the ends of the Top layer 2 shown, all of which bring an increase in the adhesive surface 6 and thus bring the aforementioned advantages.
  • Figure 3a is compared to FIG 2 a sealer geometry 6 recognizable, although also a certain step shape represents, however, the lower portion is slightly bevelled.
  • the upper area of the cover layer 2 is slightly bevelled, after which the lower one Part runs vertically.
  • FIG. 3 c shows a wave-shaped or zigzag-shaped configuration of the end; the edge of the cover layer 2 as Sealer geometry 6, in Figure 3 d is a on the underlying layers underlying beveling of the cover layer 2, the compared to a senkevier restriction also an enlarged adhesive surface offers.
  • FIGS. 3 e and 3 f show a cover layer 2 which overlies the underlying layer 2 Layers protrudes, so that according to the supernatant a sealer geometry arises at the bottom of the cover layer 2, which also designed so large that sufficient liability can be achieved.
  • the cover layer 2 on a supernatant and is about the same time hook-shaped, so that a very significant increase in the adhesive surface than Seal geometry 6 for the sealer 5 can be achieved.
  • FIG. 4 shows a sealing geometry 6 similar to FIG. 3 b.
  • To the sealer 5 optimally applied to the ends of the metal blanket 1 is the left portion of the Form template 7 designed accordingly. This design depends on how thick total of the sealer 5 is to be applied and how he adheres to the invention designed geometry of the end of the cover layer 2 to adapt.
  • FIG. 4 shows that it is advantageous to form the sealer 5 with the mold template 7 so that he with the top of the cover layer 2 closes and with a sufficient width itself over the plate ends, here plate end 4 extends, whereby also the thickness of the sealer 5 can be selected according to the total height, which is the lower level at the Form template 7 can recognize.
