Definitions

  • the present invention relates to a method and a device for the grid-like coating of web-like flexible flat structures with hot-melt adhesives in powder dot gravure and their production products.
  • Coating methods have also become known, in which the grid-shaped coating is first applied to a carrier and this is then transferred from the carrier to the fabric to be actually coated.
  • DE-B-2 536 911 for example, includes one grid-shaped powder coating on silicone paper backing and the transfer of the coating to parts of clothing by ironing the coated paper and peeling off the backing have been described.
  • DE-A-28 10 042 also describes a dot-matrix coating on an adhesive-repellent backing paper, and EP0 219 378 A1 also discloses such a dot-shaped coating by applying a grid-shaped dispersion paste to an anti-adhesive transfer carrier and transferring the adhesive dots to sheet-like fabrics.
  • the width of the transfer carrier according to EP-0 219 378 A1 must be exactly matched to the sheet of fabric to be coated, and after the transfer process the transfer carrier must be wrapped and cleaned. Seams in the transfer carrier also always have a disruptive effect. If the carrier web is guided in a circle as an endless web, the wrapping is not necessary, but instead it is difficult to guide the web precisely and without distortion and to connect it smoothly at the connection point. Pinch folds can also occur.
  • the invention is therefore based on the object of providing a method and a device for the grid-like coating of web-like flexible sheet-like structures with hot-melt adhesives in powder dot gravure, which can be carried out in a similar manner to the known coating methods without any appreciable additional outlay and the need to use web-like Avoids carrier tapes.
  • the heating roller can be pressed against the engraving roller with a pressure of about 10 N / cm (1000 p / cm), while the further roller can be pressed against the heating roller with a pressure of about 0.5 N / cm (50 p / cm) should be pressed.
  • the heating roller expediently has an anti-adhesive, rubber-like surface onto which the powder fillings of the engraving roller can be transferred by pressure.
  • This surface can be formed by a roll cover, which has a thickness of 1 to 10 mm and can consist of a soft vulcanized silicone rubber coating.
  • thermally conductive fillers such as carbon black, metal powder, metal oxide powder or the like. contain.
  • the small proportions of about 0.1-2% fatty acid for example, contain palmitic, stearic or behenic acid in a very fine distribution.
  • the transfer process should take place with a slight contact pressure which is generated by the further rotating roller which is assigned to the heating roller and between which and the heating roller the sheet is fed in and out. During this transfer process, the powder piles forming the coating flatten out. Excessive flattening can be prevented by appropriate selection of a low contact pressure on the roller.
  • the hotmelt adhesive compositions suitable for the transfer coating are the same as are used in the known processes mentioned at the outset. Powders based on copolyesters, copolyamides and polyethylenes and mixtures thereof are suitable. The grits are also the same.
  • the engraving and the coating can be in the form of dots, rods or meshes.
  • the process conditions are practically the same as for the known powder dot gravure coatings mentioned above, with the engraving roller temperatures in the temperature range of approximately 30-90 ° C. and the heating roller temperatures in the temperature range of 160-240 ° C., depending on the type of hot-melt adhesive used.
  • a wide assortment of fabrics can be coated, including those that are not or only difficult to coat due to a hairy or too open-mesh construction in the direct coating method.
  • Coated interlining fabrics based on woven fabrics, knitted fabrics, knitted fabrics, nonwovens, knitted nonwovens and woven knitted fabrics can be produced.
  • Coated synthetic leather, foils, papers, foams can also be produced without any problems.
  • the device shown in Fig. 1 has above the engraving roller 1, which is provided on its cylindrical surface with cup-shaped depressions 2 and is rotatable about its axis, a funnel-shaped storage container 3 for powdered hot melt adhesive 4.
  • This funnel sits directly on the engraving roller 1 and is open at its bottom, so that the hot-melt adhesive powder 4 can flow into the recesses 2 therein when the surface of the engraving roller is rotated past.
  • a squeegee plate attached to the funnel wall and tangential to the engraving roller ensures a smooth smear of the filled powder.
  • the engraving roller is rotated in the direction of the arrow, so that the depressions 2 filled with hot-melt adhesive powder are moved towards a heated roller 5, which can be heated and has an anti-adhesive rubber coating 6.
  • This heating roller 5, which rotates in the direction of the arrow shown in FIG. 1 in conformity with the engraving roller 1, is pressed relatively strongly onto the engraving roller, as a result of which the powder fillings located in the recesses 2 of the engraving roller are transferred to the rubber coating 6 of the heating roller and there as Put on the powder heap 7.
  • the engraving roller 1 has on the surface, in particular of its depressions, a thin separating film covering for easy removal of the powder fillings from these depressions, which can consist of a material based on tetrafluoroethylene.
  • the sheet 8 to be coated is fed in the form of a textile web 8, for example, and passed between the heating roller 5 and a further roller 9 associated therewith, which is arranged so that it presses the web 8 only slightly against the heating roller 5.
  • the heating roller is brought to a temperature of about 160 to about 240 ° C, which leads to the fact that the powder piles 7 sitting on their coating 6 sinter together. Due to the slight pressure of the web 8 against the heating roller 5, these sintered piles of powder are transferred to the web, where they form a somewhat flattened grid-shaped coating as a result of this pressure.
  • the grid-like coating can be punctiform, rod-shaped or linear.
  • the arrangement and shape of the coating grid 10 on the sheet 8 is of course determined by the arrangement and shape of the cup-shaped depressions 2 on the surface of the engraving roller. Depending on the desired type of coating grid on the fabric, these depressions 2 on the surface of the engraving roller 1 must therefore be arranged and designed accordingly.
