Definitions

  • Fabric webs with a plastic coating are known.
  • the coating can in principle be done with powder or pastes.
  • the application and distribution of the plastic can directly, i. H. for example, by sprinkling a powder on the textile base or indirectly by means of an intermediate carrier, in the form of an engraved roller or a perforated cylinder.
  • Spreading processes have the natch part that the powder is uneven due to the occurrence of electrostatic forces.
  • a method in which the powder is applied to the textile web by means of an intermediate carrier in the form of an engraved roller has the advantage of a uniform coating while eliminating the disruptive forces of electrostatic charges.
  • the material located in the recesses of the engraved roller must be applied to the fabric using heat.
  • the fabric web must be brought into contact with the engraved roller.
  • the fabric had to be heated to such an extent by upstream heat sources that when the hot fabric touched the powder contained in the recesses of the engraved and cooled roller, it immediately adhered to the fabric.
  • the powder introduced into the depressions of the intermediate carrier, while being conveyed on the intermediate carrier with the application of heat, is passed through the textile support which is guided around the intermediate carrier by more than half the circumference. set in such a sticky state that the powder adheres to the textile base when the textile base is removed from the intermediate carrier.
  • the temperature control actually only depends on the choice of powder used, which may have a higher or lower melting point, the type of textile web to be coated must be taken into account in all previously known coating methods by means of an intermediate carrier, for example an engraved roller.
  • the temperature control depends on how thick the textile web to be coated is, what color it has, what thermal conductivity or radiation permeability it has, what heat capacity it has, and what chemical nature it has.
  • the present invention relates to a method for coating a textile base made of woven or non-woven material made of natural or synthetic fibers, in which a plastic powder is applied via a recessed intermediate carrier at a temperature which prevents the powder from sticking to the intermediate carrier when applying and distributing the same , wherein the powder introduced into the recesses of the intermediate carrier is put into a so sticky state during the conveyance on the intermediate carrier with the application of heat that it is more adherent and is removed from the recesses of the intermediate carrier by contact with the textile base.
  • a method of this kind is known from the above-mentioned FR-A-2 454 334.
  • the heat is supplied directly to the powder lying in the recesses of the intermediate carrier without hindrance through the textile base.
  • the intermediate carrier can be kept at a temperature which is required in accordance with the powder to be used. This can be done by supplying or removing heat using appropriate heating or cooling agents. This depends on the type of heat supply to the powder located in the depressions of the intermediate carrier.
  • the textile web can be placed on the intermediate carrier via a press roller without other mechanical means being disregarded.
  • the heat supply to the powder should advantageously take place from outside the intermediate carrier.
  • the powder to be used and suitable for the method according to the wishes of the user is located in a powder storage container 1.
  • the powder in the storage container 1 is removed from the powder storage container 1 by means of a metering device in accordance with the amount of the recesses provided in an intermediate carrier 5.
  • a possible embodiment of such a metering device can be a metering roller 2. Vibrating screens or rotating brushes can also be considered without other metering devices, as are known in the art, being excluded.
  • a powder curtain falls from the powder metering device into a powder distribution and application space 3, which is delimited at least on one side by a cooled doctor blade 4, but preferably on two sides by cooled doctor blades 4.
  • the two squeegees 4 shown here as a doctor blade 4 are in contact with the surface of the intermediate carrier 5.
  • the cooled squeegee 4 with respect to the direction of movement of the intermediate carrier 5 ensures complete filling the recesses in the intermediate carrier with powder and scrape off the unnecessary amount. With the correct dosage of the powder supply, there is always only a small amount of powder in room 3, which is continuously processed.
  • the intermediate carrier 5, which acts as the conveying surface of the powder can be a so-called engraved roller known in powder coating technology, without this precluding differently designed intermediate carriers 5 as conveying surfaces.
  • the intermediate carrier can be equipped with coolant and / or heating medium in order to bring about a constant temperature of the surface.
  • one or more heat sources 7, 8, 9 can supply heat directly to the powder lying in the depressions in a manner which is matched to the powder.
  • the base to be coated is not in the way here.
  • the regulation of the heat supply therefore only needs to be matched to the powder to be used.
  • the underlay itself is not exposed to these undesirable effects of heat.
  • the heat is supplied without contact, i. H. by means of heat radiation or by means of heat conduction or heat transfer. Combinations of different heat sources are also possible. Depending on this, heating surfaces or rollers, radiant heaters or hot air can be considered as sources of heat.
  • the plastic powder lying in the recesses of the intermediate carrier is softened and melted on the layer closest to the heat sources in such a way that large pushing forces develop here.
  • the substrate to be coated is then brought into contact with the powder, which is now extremely sticky, at this heat supply zone.
  • the substrate 11 to be coated can be guided around or along a pressure roller 10, which presses on the intermediate carrier 5 with the interposition of the substrate.
  • the extremely sticky powder now immediately adheres to the base to be coated and is drawn from the base 11 of the intermediate carrier 5 by the base 11 running around the press roller 10.
  • the temperature control can be regulated by means of cooling and heating means in the press roller 10, with which a temperature gradient can be achieved between the surface of the intermediate carrier and the substrate to be coated.
  • the area of the intermediate carrier provided with powder is at least as wide as the surface to be coated.
  • the surface of the intermediate carrier provided with powder must also be aligned with the surface of the surface to be coated. This can be done either by powder removal from the heat supply zone, by suctioning off the powder 6 that cannot be brought into register with the base to be coated, or by appropriate control of the lateral guidance of the textile web 11.
