Definitions

  • the invention relates to a method for producing a self-adhesive cover according to the preamble of claim 1.
  • DE-C-3 334 800 describes a tarpaulin for covering components, such as windows and doors, with an adhesive layer arranged on the inside in a strip-like pattern and a special perforation for tearing off any protruding tarpaulin parts.
  • US-A-2 510 120 also describes masking paper with a strip-shaped adhesive application which is stretchable to a certain extent and is also suitable for uneven surfaces.
  • DE-U-81 24 143 describes a removable, self-adhesive workpiece protective film made of plastic in a stripe for easier removal after covering and possibly re-use.
  • the known self-adhesive cover films have considerable disadvantages. For large-scale surface protection, it is desirable to use inexpensive, thin films on the one hand, but on the other hand large widths, especially over 1 m, in order to be able to cover large areas without denomination.
  • the known cover films are neither adequately manageable nor can they be produced on an industrial scale on conventional systems. Also, thin LDPE or HDPE films can hardly be coated conventionally, since they are sensitive to heat and gasoline.
  • the object of the invention is to remedy this, in particular to avoid or at least reduce the disadvantages of the prior art, in particular to provide a method for producing a self-adhesive cover with adhesive in the stripe line, which is also available in large widths and with thin supports Foils leads to practically usable products.
  • the present invention describes a method for producing a cover of the type specified in claim 1, with advantageous configurations according to the dependent claims.
  • the covers according to the invention can be produced by means of suitable devices.
  • Known longitudinal folding devices can thus be used to fold the carrier in a zigzag shape, consisting of a unwinding station in which the carrier is unrolled from a roll, the actual folding station with an upstream spreader roller, and a reeling station in which the folds in turn are closed a much narrower roll is now being wound.
  • the folded carrier can advantageously be coated "in line” with adhesive, dried and wound up in the folded state and sold in rod form in various lengths and widths.
  • Unwinding and application preferably correspond to the state of the art.
  • the folding device exists in particular from interlocking upper slats and lower slats, which are inclined at an angle parallel to one another to the horizontal, in order to facilitate the later laying of the carrier.
  • at least one set of lamellas should be arranged in a wedge shape.
  • the middle lamella or the middle lamella pair of this wedge-shaped arrangement then has the longest lamella with two further but shorter lamellae arranged in pairs offset on both sides around the middle in the running direction.
  • the folded carrier is optionally provided with a primer and varnish and coated with a suitable self-adhesive.
  • Coating methods for this are screen printing, in particular in accordance with DE-A-3 346 100 for products which can be glued reversibly, and in a conventional manner with adhesive compositions in solvents via strip coating, Acutrack or Reco rolling mill.
  • covers according to the invention with approximately 3 to 25 g of adhesive per m2, in particular 5 to 10 g / m2 or with adhesive points via screen printing, as are preferably described in DE-OS 3,346,100, are particularly suitable .
  • About 1/3 of the surface is preferably coated, so that with a coating machine width of 1 m, approximately 3 m wide foils can be processed.
  • suitable carriers for the cover are in particular thin plastic films, produced in one or more layers, as are characterized in more detail in the examples and subclaims.
  • a 2 m wide HDPE film of 25 ⁇ m (My) thickness is subjected to an accordion fold and placed in folds of 1 cm width, the original width decreasing from 2 m to about 80 cm (theoretically: 67 cm).
  • this folded film carrier is coated with the adhesive described there using screen printing, application weight 5 g / m 2, screen size 80 mesh.
  • the drying channel is dried at 60 ° C and the finished product is wound into a roll.
  • Example 2 As described in Example 1, a 15 ⁇ m (My) thick HDPE film is folded and coated, this time with a 17 mesh screen, again dried at 60 ° C. and wound into a roll.
  • a 50 ⁇ m (My) thick LDPE film is folded and coated with 5 g / m2 and 80 mesh screen. It is dried at 60 ° C and then wound into a roll.
