Definitions

  • the present invention relates to a varnishing plate, and in particular to a reversible varnishing plate, known also with the name of varnishing caoutchouc, which can be employed in the printing machines for offset printings.
  • US 6205922 discloses a reversible printing blanket, therefore not a varnishing plate, comprising at least one support layer arranged between two printing surfaces, wherein one or more polymeric layers are firmly joined between the support layer and the printing surfaces.
  • the printing surfaces and/or the polymeric layers have different physical and/or chemical characteristics, so that with the same blanket two different printing processes can be carried out by simply reversing the printing blanket.
  • both varnishing surfaces of the varnishing plate according to the present invention can be partially detached from the support layer, so that a varnishing surface or the opposite surface can be employed by reversing the varnishing plate.
  • Different configurations of the varnishing plate can be obtained by employing polymeric layers which allow an easier removal of a varnishing surface from the support layer and/or compressible layers which allow to absorb thickness differences or irregularities, if any, of the support to be varnished and/or stabilizing layers which reduce the movements in the directions parallel to the varnishing surface.
  • the varnishing plate according to the first embodiment comprises in a known way at least two varnishing surfaces 1, 2, for example of nitrile rubber, butyl rubber, EPDM (Ethylene-Propylene-Diene-Monomer) rubber, SBR (Styrene Butadiene Rubber) rubber, polyurethane, polypropylene, polyethylene, PVC (polyvinyl chloride) or other thermosetting or thermoplastic elastomers, having a thickness comprised between 0,02 mm and 1 mm and/or a hardness comprised between 30 and 95 ShA (Shore A).
  • varnishing surfaces 1, 2 for example of nitrile rubber, butyl rubber, EPDM (Ethylene-Propylene-Diene-Monomer) rubber, SBR (Styrene Butadiene Rubber) rubber, polyurethane, polypropylene, polyethylene, PVC (polyvinyl chloride) or other thermosetting or thermoplastic elastomers, having a thickness comprised between 0,02
  • At least one support layer 3 is arranged between varnishing surfaces 1, 2 and is made for example of a paper material, plastic material such as polyester, polyethylene, polypropylene, PVC, PMMA, PC, or metallic material such as aluminum or steel.
  • Support layer 3 has a thickness comprised between 0,05 and 1 mm and/or a Young Module comprised between 1000 MPa and 15000 MPa (ASTM) and/or a break resistance comprised between 5 and 500 MPa (ASTM).
  • At least one polymeric layer 4 is arranged between support layer 3 and varnishing plates 1 and/or 2.
  • the polymeric layer is joined to varnishing plate 1.
  • Polymeric layer 4 comprises for example adhesive resins polyester-based, polyurethane-based, epoxy, NBR rubber, EPDM rubber or other thermoplastic or thermosetting elastomers.
  • Polymeric layer 4 has a thickness comprised between 0,02 mm and 1 mm and/or a hardness comprised between 30 and 95 ShA (Shore A).
  • Both surfaces of support layer 3 are coated by a removable adhesive 5, so that varnishing surface 2 and/or polymeric layer 4 joined to varnishing surface 1 can be detached from support layer 3.
  • the adhesive force of removable adhesive 5 is lower than 0,6 N/mm, in particular lower than 0,2 N/mm and greater than 0,01 N/mm (ISO 32 or ISO 8510-2).
  • the varnishing plate according to the second embodiment comprises a further polymeric layer 6 arranged between support layer 3 and varnishing surface 2.
  • the varnishing plate according to the third embodiment comprises at least one compressible layer 7 arranged between support layer 3 and varnishing surface 2.
  • Compressible layer 7 comprises a layer in an expanded polymeric material with closed cells and/or can contain microspheres.
  • compressible layer 7 can comprise a thermosetting elastomer made of NBR (Nitrile Butadiene Rubber), EPDM, IR (Isoprene Rubber), IIR (Isobutene Isoprene Rubber) rubber.
  • Compressible layer 7 has a thickness comprised between 0,1 mm and 1 mm, and a density lower than 1,4 Kg/dm 3 .
  • the density of compressible layer 7 is preferably lower than the density of polymeric layers 4 and/or 6.
  • the varnishing plate according to the fourth embodiment comprises at least one stabilizing layer 8 arranged between support layer 3 and varnishing surface 2, in particular between polymeric layer 6 and varnishing surface 2.
  • Stabilizing layer 8 comprises for example a technical fabric or a thin layer of polyester with a thickness of 0,5 mm or a high-tenacity elastomeric layer reinforced with natural, polymeric or metallic short fibers.
  • Said technical fabric can be for example a cotton fabric with 23 warp yarns per cm and 18 weft yarns per cm, having a thickness of 0,35 mm and a break load of about 500 N.
  • a high-tenacity polymeric layer can be used, such as for example a thermosetting polyurethane or other thermosetting elastomer, reinforced with fibers made of Polyvinyl alcohol (PVA), Kevlar, steel or other resistant fibers.
  • PVA Polyvinyl alcohol
  • Kevlar Kevlar
  • the varnishing plate according to the fifth embodiment comprises a stabilizing layer 8 arranged between support layer 3 and varnishing surface 2, in particular between compressible layer 7 and varnishing surface 2.
  • the varnishing plate according to the sixth embodiment comprises two support layers 3 which are provided with a removable adhesive 5 on one or both surfaces and are arranged between varnishing surfaces 1, 2, in turn joined to a first polymeric layer 4 and/or to a second polymeric layer 6, respectively.
  • a compressible layer 7 and/or a polymeric layer are arranged between support layers 3.
  • the varnishing plate according to the seventh embodiment comprises a support layer 3 arranged between two polymeric layers 4, 6, wherein a compressible layer 7 is arranged between polymeric layer 6 and varnishing surface 2.
  • Removable adhesive 5 can include and/or consist of any surface treatment or substance which are not adhesive in themselves but which allow the joining in a removable manner and therefore the easy removal of varnishing surfaces 1, 2 from support layer 3.
  • said substance can be a thermo-activable substance applied to the surfaces of support layer 3 and/or to the surfaces contacting the latter before the vulcanization of varnishing surfaces 1, 2 together with support layer 3, so that during this vulcanization said joining to support layer 3 is obtained.
