Definitions

  • the coating can be carried out with powder or pastes.
  • the application and distribution of the plastic can be direct, i.e. 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 methods have the disadvantage that the powder precipitates unevenly 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 with the elimination of the disruptive forces of electrostatic charges.
  • the application of the material located in the recesses of the engraved roller to the fabric must be done using Heat.
  • the fabric web must be brought into contact with the engraved roller.
  • the dual task of firstly bringing the powder through contact with the engraved conveying surface onto the web of material and secondly supplying the plastic powder with the necessary heat so that it develops the necessary adhesive force to adhere to the web of material has so far not been able to be solved separately.
  • the fabric web had to be heated up to such an extent by upstream heat sources that when the hot fabric web touches the powder in the recesses of the engraved and cooled roller, the powder immediately adheres to the fabric web.
  • Another method provides for the powder to be melted through the textile base lying against the engraved roller and thus to be adhesively bonded to the base.
  • the temperature control is dependent 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 consists of
  • 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 the powder over an intermediate carrier provided with recesses, in which the powder sticks to the intermediate carrier during application and Distribution of the same avoiding temperature.
  • the heat is supplied directly to the powder lying in the recesses of the intermediate carrier without hindrance through the textile base.
  • the omission of the textile underlay in the area of heat supply to the powder greatly simplifies the entire temperature control, since only constant machine factors and the only varying plastic powders have to be taken into account in the temperature control.
  • the intermediate carrier can be kept at a temperature required by 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 recesses 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 be from outside the intermediate carrier.
  • the powder which is to be used for the method and is suitable for the method 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 taken.
  • a possible embodiment of such a metering device can be a metering roller 2. Vibrating screens or rotating brushes can also be used. without excluding other metering devices, as are known in the art.
  • 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 doctor blades 4 shown here as a doctor blade 4 are in contact with the surface of the intermediate carrier 5.
  • the cooled squeegee 4 which follows with respect to the direction of movement of the intermediate carrier 5 ensures a completely fill the wells in the intermediate carrier with powder and scrape off the excess.
  • the intermediate carrier 5, which acts as the conveying surface of the powder, can be a so-called jin of the powder coating Technically known engraved roller without this excludes differently shaped intermediate supports 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 act directly on the powder lying in the depressions in a manner coordinated with the powder.
  • the substrate 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 heat influences.
  • the heat is supplied without contact, ie by means of heat radiation or by means of heat conduction or heat transfer. Combinations too * Different heat sources can be realized. Depending on the heat sources, heating surfaces or rollers, radiant heaters or hot air come into question.
  • 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 great adhesive 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 underlay 11 to be coated can be guided around or along a pressure roller 10 which presses on the intermediate support 5 with the interposition of the underlay.
  • 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 coolant in the press roll 10, with the result that a temperature gradient between the surface of the intermediate carrier and the
  • OMPI coating surface can be achieved.
  • the surface of the intermediate carrier provided with powder is at least as wide as the base to be coated.
  • the powder-coated surface of the intermediate carrier must also be brought into line with the surface of the substrate to be coated. This can be done either by removing powder in front of the heat supply zone, by adding the powder which cannot be brought into register laterally with the substrate to be coated
  • the intermediate carrier can, if necessary, also be provided with a Teflon layer.

Abstract

Lors de procédés connus d'enduction de supports textiles avec un produit synthétique en poudre, on soumet le support textile à des traitements thermiques; soit le pan d'étoffe sert au transport de la chaleur, soit il est traversé par un rayonnement thermique. Le présent procédé permet d'éviter cela. Grâce à une installation de dosage (2), le produit synthétique en poudre passe d'un réservoir de stockage de poudre (1) au compartiment de distribution et d'apport de poudre (3) où il est distribué sur une surface de transport (5) grâce à un racloir (4). Des sources de chaleur (7-9) agissent sans contact, directement sur le produit synthétique en poudre situé sur le porteur intermédiaire. Le support à enduire (11) est pressé grâce à un cylindre de pression (10) contre le porteur intermédiaire (5) où la poudre en grande partie adhésive adhère tout de suite au support textile (11).
