Definitions

  • the invention relates to a method for producing patterned tiles from thermoplastic materials, in particular for floor coverings, or the like from uni- and / or differently colored chips, granules, particles, chips or the like.
  • a raw skin sheet is produced from thermoplastic materials by compaction, such as rollers or presses, and raw skins are cut to length from this and are pressed to the tiles using heat and, if necessary, are finally annealed.
  • thermoplastic plastics by rolling and calendering, patterns being produced by using differently colored particles of thermoplastic plastics and sprinkling and incorporating such particles into the thermoplastic synthetic web.
  • the object of the present application is to create inlaid tiles based on differently colored or patterned thermoplastic synthetic sheets.
  • the method according to the invention achieves the object in such a way that raw skins are stamped into segments from differently colored thermoplastic materials and the segments from at least two different colored raw skins are joined together to form a plate and then the segments are applied using pressure and heat Inlaid tile pressed and welded together along the joints.
  • rawhides are made by rolling or pressing small particles of thermoplastic, but they are not yet fully compacted and have a rough surface.
  • the particles for the production of the rawhides can be based on a vinyl polymer and / or copolymers of vinyl chloride, such as polyvinyl chloride containing plasticizers and, if appropriate, further auxiliaries and fillers, stabilizers, color pigments, etc.
  • Can chen the part l also at least partially in addition other thermoplastic polymers such as acrylates polyester, ethylene vinyl acetate, etc. Marsh.
  • Die particles can also be a colored and / or conductive sheath, for example based on colorants, 'carbon black pastes and metal are provided pastes.
  • An advantageous embodiment of the invention provides that - the raw skins are punched into a segment frame and loose segments and different-colored segment frames and segments are joined together to form a plate.
  • a preferred embodiment of the method according to the invention provides that the raw skins are punched into segments without punch play.
  • this has the disadvantage that difficulties may arise when assembling the segments to form the plates due to the lack of play.
  • These problems are countered according to the invention in that the loose segments to be inserted into a segment frame are at a temperature which is at least 5 ° C. lower than the temperature of the Segment frame is cooled and then assembled in a cooled form to the plate.
  • the pressing of the folded plates using pressure and heat is preferably done in so-called multi-level presses.
  • Such stack presses usually have predetermined dimensions of the press plates or press plate frame.
  • the inlaid tiles produced here can then be punched to size, depending on the desired size and shape of the inlaid tile.
  • a raw skin 11 is shown in a top view in FIG.
  • the segments 11 A and 11 B are punched out of this raw skin 11 according to the size of, for example, the press plate frame of a deck press, leaving the edge section 11 C.
  • 11 B represents a segment frame
  • 11 A are loose segments.
  • a segment frame 24 B and segments 24 A are punched in the same way from a second raw skin 24, which is colored differently from the raw skin 11 and is not shown here.
  • FIG 3 shows how a segment frame 11 B with segments 24 A of different colors are assembled and inserted into a plate in a press plate frame 18.
  • the joints 26 are welded between segment frames 11 B and segments 24 A and at the same time the raw hide segments are ver seals and the plate is uniformly and uniformly pressed.
  • FIG. 5 schematically shows how inlaid tiles are produced from two raw skins 11, 24 of different colors by corresponding mutual supplementation.
  • the desired size of the inlay tiles and the specified size of the press plate frame it is possible to subdivide the finished pressed inlay plate along the cutting edge 25 shown. It is also appropriate to provide the pressed plate with a hem cut.
  • the outer shape of the inlaid tile does not have to be rectangular, it can also be triangular, hexagonal or in another curved shape that can be folded into continuous surfaces.
  • the method according to the invention is further explained below using the schematic flow diagram according to FIG. 1.
  • a feeder 1 chips, chips or the like. placed on two of single-colored or differently or multicolored thermoplastic plastics on the conveyor belt 3 and fed to the rolling mill 4, 5 for producing the rawhide web.
  • the rawhide web 6 is then optionally fed to a smoothing unit or grinding rollers via take-off rollers and subsequently to the stamping device 9 for marking the Roll direction passed. This marking of the rolling direction serves to facilitate the insertion of the segments in the press plate frame.
  • the individual raw skins 11 are subsequently cut to length from the raw skin web 6 on the cross cutting device 10. It is also possible to feed prefabricated rawhide sheets directly to the stamping device and the cross cutting device for cutting rawhide to length.
  • raw skins with different patterns are produced at this point, that is to say further raw skins 24, etc.
  • These raw skins are then fed to a punch 13 which punches out the segments from the raw skin.
  • band steel cutting knives can be provided for the segment punch.
  • the stamped segments are separated after leaving the punch 13, namely into the loose segments A, which are fed to a cooling device 14 and the remaining segments, in particular segment frames B, which are fed directly to an insertion device 17 for producing the inlaid panels.
  • the segments A are cooled in the cooling device to approximately 5 to 15 0 C, ie a temperature which is at least 5 ° C below room temperature, stored at the rest of the segment portions B.
  • segments A, B of different colors are joined to the plate 20 on the insertion device 17, which is provided with a press plate frame 18, covered on the upper side with a further press plate and then fed to the deck press 19.
  • the assembled plates 20 are then pressed and welded in the deck press 19 at pressures between 30 to 100 N / cm 2 and temperatures of 150 to 190 ° C. and press times between 20 and 80 minutes.
  • the pressures, temperatures and press times used depend on the thickness of the plates and the materials used.
  • the finished pressed plates 21 are then removed from the press plate frame and fed to a format punch 22 for final external shaping.
  • the finished pressed inlay tile 23 is then subsequently tempered in order to relieve residual stresses in the material.
