Definitions

  • the present invention relates to a screen printing stencil with a screen printing stencil carrier in the form of a rectangular flat structure with a at least in predetermined sections from a photo layer existing coating.
  • a screen printing stencil of the type described above is in the DE-A-2 324 330.
  • the object of the present invention is to create screen printing stencils, which are also suitable for the formation of Screen printing cylinders with large printing lengths (over 1000 mm) and Print widths (over 700 mm) are suitable.
  • the actual template production should be done in a flat state and the Reusability of the template carrier can be guaranteed.
  • the formation of the printing cylinder in the printing unit itself and the Returning to the flat state should be easy to be possible.
  • This task is the beginning of a screen printing stencil defined type according to the invention solved in that the Stencil holder forming a screen printing plate on one Subframe consisting of two longitudinal profiles and two die rigid longitudinal profiles connecting the two longitudinal profiles, is attached, the longitudinal profiles made of resilient Material exist and are designed in cross section so that they come out of the flat shape by external force Let it bend resiliently around which the screen printing template forming screen printing plate at least to form a partial cylinder, when the external forces, however, automatically return to their flat Reduce the original form.
  • the flat screen printing plate formed from the actual template holder and the associated subframe thanks to the special design of the longitudinal frame profiles easily formed into a cylinder in the printing unit itself and be placed on the cylinder hubs without using the the closed subframe of the template carrier is damaged, crumpled or otherwise deformed.
  • the frame profiles are usually formed by metal strips (spring-hard sheet metal) and have a special cross section (similar to the domed ones Blind slats), which has sufficient frame stability in the ensures flat condition, but a bend (Cylinder formation) due to slight external force enabled (after exceeding the respective "break point").
  • the cross profiles of the frame have a quick release mechanism (e.g. Z-Profiling), which together with a sealing strip the formation of a closed Allow cylinders.
  • Z-Profiling e.g. Z-Profiling
  • These cross sections get thanks to this Training also provides maximum bending stiffness with minimal Sheet thickness.
  • the individual frame profiles are usually welded connected with each other.
  • connection of the actual template carrier (plastic or metal mesh or perforated film with an applied photo layer) with the Subframes are preferably made by gluing or welding.
  • the template can be large-format screen printing plates produce practically all dimensions and as a screen printing cylinder use in rotary screen printing.
  • the Dimensions of the longitudinal and transverse profiles of the subframe can be easily adapted to the respective requirements.
  • the stencils according to the invention which are used for formation of printing cylinders, could of course also in the flat state, i.e. used as a screen printing plate will.
  • the actual screen printing stencil carrier in the form of a rectangular flat The structure usually consists of a stabilized fabric or a foil, pre-punched e.g. as galvano stencil or punched, e.g. etched or laser processed.
  • Fig. 1 of the drawing shows schematically an existing subframe from two longitudinal profiles 1, 2 and two welded to it stiff cross sections 3, 4.
  • This subframe is relatively stable when flat, i.e. he stays with Manipulations in the flat plate form.
  • Fig. 2 is a stencil holder 5 in the form of a stabilized tissue, in particular a metal mesh or a perforated film, with at least in sections on it applied photo layer 6, on both sides on the longitudinal profiles 1, 2 of the subframe attached (e.g. glued on).
  • the cross profiles are preferred to form a quick release fastener (see Fig. 3 and 4) formed together with a locking bar 7.
  • the attachment of the template carrier (fabric 5, 6) to the Longitudinal profiles 1, 2 are preferably carried out in the neutral area Zone of the latter (no influence when bending). Using A suitable adhesive is the place of attachment however not critical.
  • the connecting bar 7 for the cross sections 3, 4 can also by be pushed on the side.
  • the screen printing cylinder can be installed in the printing unit itself, this by laying on the bending template lateral support discs (hubs) for the cylinder.
  • the great advantage of the screen printing stencil according to the invention lies in the fact that all processing steps (including the production the actual print template; Processing for reuse etc.) in the flat state can be done and that training as a cylinder on easiest way can also be done in the printing unit itself.
