Definitions
- the invention relates to a method and a device for applying a partial surface coating to a web with the features of the preamble of the independent claims.
- the surface coating consists of a thermoplastic hot melt adhesive.
- a thermoplastic hot melt adhesive for example, copolyamides and copolyesters are used.
- the hot melt adhesive is heated and applied to the web in the manner described using an engraving roller or the screen printing process.
- the adhesive and all machine parts that come into contact with the adhesive are generally heated.
- the engraving roller or the screen are limited to the processing temperature of the plastic mass, which is typically in the range between 150 ° C and 220 ° C.
- a disadvantage of these known devices is that the amount of plastic compound applied is difficult to control. In addition, with light and open textiles there is a risk that the adhesive will break through, i.e. is pressed through the web. This is particularly critical with large volumes (e.g. large dots).
- a partial surface coating is produced on a web by partially applying a flowable, heated plastic mass to at least one surface of the web.
- partial means that only. part of the surface is coated.
- the web of material is moistened before or when the plastic mass is applied.
- the moistening means that the liquid is evaporated during the application of the plastic mass, ie in particular when the material web comes into contact with an application device with, for example, an engraving roller or a screen printing drum.
- the liquid is typically water. Evaporation removes heat of vaporization from the system.
- the plastic mass is cooled down.
- the applied surface coating is frozen to a certain extent quickly.
- the surface coating for example a dot, adheres only superficially to the web. This also ensures that no puncture occurs in a subsequent lamination process when the web is reheated.
- the web is sprayed. Spraying makes it particularly easy to adjust the amount of liquid to be applied.
- water is advantageously used as the liquid. Water generally does not attack the web and the adhesive and is particularly characterized by a high heat of vaporization. However, other liquids are also conceivable.
- the plastic compound can be applied in a manner known per se using an engraving roller or screen printing. However, other application devices would also be conceivable.
- the prior moistening is essential for the present invention.
- the amount of liquid applied is adjusted such that essentially all of the liquid is evaporated during the contact of the material web with the application device.
- the device according to the invention is accordingly distinguished by a moistening unit for moistening the material web, which is arranged in front of the application device when viewed in the direction of travel of the material web.
- the moistening unit can have a spray nozzle or a roller for roller application of the liquid.
- application devices for indirect application of the surface coating for example via a transfer roller, are also conceivable.
- the device according to the invention and the method according to the invention can be used particularly easily to apply a partial surface coating.
- the moisture can evaporate because there are uncoated sections on the web. A negative effect of the liquid on the surface coating is therefore not to be feared.
- the surface of the engraving roller can also e.g. can also be heated with an electric heater. This allows the temperature to be stabilized.
- Figure 1 is a schematic representation of a first embodiment of the invention
- FIG. 2 is a schematic representation of an alternative embodiment of the invention.
- Figure 3 shows an alternative embodiment of a humidification arrangement.
- FIG. 1 shows schematically a device 1 for applying a partial surface coating 0 to a web W.
- the material web W is guided through the device 1.
- a dot-shaped coating 0 is applied to a surface 2 of the material web W.
- a punctiform coating on both sides of the goods W wear. Coatings other than punctiform, for example lines, are also conceivable.
- the device 1 essentially consists of an application device 3.
- the application device 3 has an engraving roller 5.
- a doctor blade 6 with an application head for a hot-melt adhesive K
- the hot-melt adhesive K is entered into depressions, shown schematically, on the surface of the engraving roller 5.
- points of the hot melt adhesive K are transferred to the surface 2 of the web W.
- a counter roller 7 is arranged on the opposite side, which presses the web W against the engraving roller 5.
- the counter roll 7 is made of rubber, for example, and is cooled.
- the application device 3 is essentially designed in a known manner.
- the engraving roller 5, the doctor blade and application head 6 and the hot-melt adhesive K are heated or heated.
- the adhesive is typically heated to a temperature of 200 ° C.
- the engraving roller 5 and the doctor blade 6 are typically on. a temperature slightly below this value.
- a moistening unit Seen in the running direction L of the web W in front of the application device 3, a moistening unit is arranged.
- the humidification unit has a spray nozzle 22. With the spray nozzle 22, a liquid F is applied to the web.
- the amount of liquid F is typically selected so that the web W is moist in an area II and is essentially dry in an area I after contact with the heated engraving roller 5. This means that when the hot melt adhesive K and the engraving roller 5 come into contact with the liquid F in the substantially completely evaporated, the hot melt adhesive K in particular being cooled.
- the amount of liquid is about 5 to 50 g / m2.
- the liquid is generally water. In the exemplary embodiment shown, this amount of water is sufficient at a processing speed of between 10 and 200 m / min. for cooling adhesive K heated to 200 ° C in the amount of 3 to 30 g / m2.
- the spray nozzle 22 is a commercially available precision spray system. Such spray systems are available from Weko, for example.
- the spray system 22 is arranged on the same side of the web W as the engraving roller 5. However, it would also be conceivable to moisten the web W on both sides or only from the opposite side of the coating.
- FIG. 2 shows a device 1 in which the surface coating O is applied using an alternative application device 13.
- the application device 13 has a screen printing drum 15.
- a doctor blade 16 with an application head for the adhesive K is provided in the interior of the screen printing drum 15.
- the screen printing drum 15 is heated in an infrared zone 18.
- the adhesive K is supplied heated as in the embodiment according to FIG. 1.
- a moistening unit is arranged in front of the application device 13, with which liquid F is applied to the surface 2 of the web W. Otherwise the process parameters are according to Exemplary embodiments in FIG. 2 are essentially identical to the exemplary embodiment according to FIG. 1.
- the hot melt adhesive K is, for example, a copolyamide or a copolyester.
- the web W is typically a textile structure, for example a polyester fabric or knitted fabric.
- the device 1 is followed by an infrared zone 8, which is used to cut off any adhesive threads that may form when the spherical caps are emptied.
- FIG. 1 An alternative exemplary embodiment for a humidification unit is shown in FIG.
- the liquid F is applied to the web W by roller application.
- a liquid F is held in a liquid container 11.
- a roller 12 is rotatably mounted in the liquid container 11, so that its surface 10 can be passed partially through the liquid F.
- the material web W is pressed against the surface 10 of the roller 12 with a deflecting roller, whereby liquid F, which adheres to the surface 10, is transferred to the material web W.
- a metering roller 9 is used to adjust the liquid adhering to the surface 10 of the roller 12.
