Definitions

  • the invention relates to a method for applying liquid, pasty or plastic substances, in particular thermoplastics, through perforations of a cylinder, tape or the like on a substrate, in particular a textile fabric, and a device therefor.
  • the cylinder, the belt or the like encloses an interior which is preferably continuously evacuated during the coating process.
  • the weight of the coating is checked periodically or continuously. This can be done by determining the height and area of the coating.
  • a corresponding method is particularly suitable for a punctiform coating.
  • the punctiform coating creates coating knobs which have a certain height and surface area, by means of which both the weight and the quality of the coating are determined. Based on the measurement of the height and surface area, a conclusion can be drawn about the weight of the coating.
  • stroposcope lamps are used to determine the height and surface area of the coating, which record the height and surface area. Height and / or surface area can be monitored using a monitor the coating knobs are observed.
  • the monitor is provided with a corresponding grid, into which the coating knobs must fit.
  • the coating knobs determined by the stroposcope lamps fall out of the grid, the coating is either too thick or too thin.
  • the grid fields are monitored by a computing unit and can be changed.
  • the computing unit uses the grid fields to determine the weight of the coating, compares it with a target value and changes the supply of the coating material accordingly.
  • a weight measurement is provided, in which, in a preferred exemplary embodiment, the substrate is guided over a correspondingly mounted roller.
  • the role can be based on corresponding supports that are deformable.
  • the deformation is recognized by appropriate strain gauges.
  • the present invention should not be limited to this.
  • a foaming agent or gas is added to the coating substance.
  • This foaming agent or gas has the effect that, for example, coating nubs decrease in their tightness and a pressure more give in. This keeps the entire coated fabric softer.
  • a powder for example, which foams at a certain temperature can be selected as the foaming substance. The foaming can already take place when the substance is melted, but in a preferred exemplary embodiment a powder should be selected which foams only in the coating head or when applied to the substrate.
  • a device for applying liquid, pasty or plastic substances, in particular thermoplastics, through perforations to a substrate, in particular a textile fabric is also provided, in which the perforations are formed in an endless coating band which wraps around a drive roller.
  • the metal cylinder has been driven by means of an organ arranged on the outside of the metal cylinder, for example a pulley. This caused difficulties in starting the device in that the metal cylinder warped in starting. This was especially the case when coating substance from the previous coating process still adhered to the metal cylinder.
  • the drive roller now provided according to the invention, which of course could also be used in a known metal cylinder, drives the cylinder or the belt uniformly over its entire length, so that there is no longer any distortion.
  • the drive roller should be provided with a rubber jacket. However, it can also be considered to design the drive roller as a spiked roller.
  • a doctor blade In the interior of the coating belt, a doctor blade should be connected upstream of the drive roller, which still removes coating material adhering to the coating belt. This protects the drive roller.
  • the drive roller can form a coating gap with the counter roller in which a substrate is coated.
  • the gusset between the drive roller and the coating belt then forms a receiving channel for the coating substance.
  • a device P according to the invention for coating a textile substrate 1 has a perforated metal cylinder 2, inside which there is a coating head 3. Molten thermoplastic coating material reaches the inner surface of the metal cylinder 2 through a chamber 4 and a nozzle slot 5 and is expressed through the holes 6 shown in FIG. This material hits the substrate 1.
  • the coating takes place in cooperation with a counter-pressure roller 7, the substrate 1 being guided in a coating gap 8 between the counter-pressure roller 7 and the metal cylinder 2.
  • a coating device is shown for example in DE-OS 36 38 307.4 and DE-OS 38 26 395.5.
  • a vacuum pump 9 is connected to the metal cylinder 2, to which a separating container 10 is assigned.
  • the metal cylinder 2 is closed on all sides and only has the holes 6 mentioned.
  • the vacuum pump 9 continuously removes air from the interior I of the metal cylinder, which the cylinder must suck in again through the holes 6. With this, however, vapors, which are created during the coating by the melted thermoplastic coating material, are also extracted.
  • the separation container 10 serves to intercept and dispose of any condensate of these vapors that may accumulate in or on the vacuum pump 9.
  • sealing lips 11 which form a nozzle mouth 12 at the outlet of the nozzle slot 5 and which lie against the interior of the metal cylinder 2. These should be made from a ceramic material, and preferably from a zirconium oxide. The sealing lips are then screwed into the steel of the loading head as zirconium oxide strips.
  • FIGS. 3 and 4 A further embodiment of a device P1 for coating a textile substrate 1 is shown in FIGS. 3 and 4.
  • a perforated coating tape 13 is guided as an endless tape around a drive roller 14 and two deflection rollers 15 and 16.
  • the drive roller 14 is preferably covered with a jacket, for example a rubber jacket 17, which increases the friction towards the coating belt 13.
  • the drive roller 14 runs through the length of the coating tape 13, making carrying the coating tape 13 much easier.
  • a corresponding drive for the drive roller 14 is shown schematically in FIG. 4. This is a drive motor 18, the rotational movement of which is transmitted to a drive shaft 20 via a transmission gear 19.
  • the inner surface of the coating tape 13 is also assigned a doctor blade 21 with a collecting container 21a, through which coating material is scraped off before the coating tape 13 loops around the drive roller 14. Corresponding discharges of the stripped material and a level indicator the coating material 25 are not shown.
  • the drive roller 14 interacts with a counter roller 22.
  • the axis 23 of the counter roller 22 is arranged approximately in a horizontal plane with the axis 24 of the drive roller 14.
  • the axis 23a of the counter roller 22a is offset upwards, so that the coating strip 13 is indented.
  • Coating material 25 is poured into the space between drive roller 14 and coating belt 13 and this is expressed in the gap 26 between drive roller 14 and counter roller 22 by the perforations of the coating belt on a substrate (not shown in more detail).
  • the drive roller 14 can also be a spiked roller or the like instead of a roller provided with a rubber jacket 17.
  • FIGS. 7 to 9 are primarily concerned with the possibility of determining how much coating material is on the substrate. The quality of the coating depends on an even coating. According to the invention, in a first exemplary embodiment according to FIG. 7, the substrate is guided over a roller 27 after the coating gap 8.
  • the role 27 is assigned stroposcope lamps 29 and 30, which can be monitored via a monitor (not shown in more detail).
  • a monitor not shown in more detail.
  • a height-wise and area-wise detection of the coating knobs 28 is carried out by the latching fields 31. This is done as follows:
  • a nub which is detected by the stroposcope lamps 29 and 30, is generally located off-center, as is indicated by the broken line.
  • Appropriate adjustment devices are then used to adjust the stroposcope lamps 29 and 30 in such a way that the coating knob 28 is located within the rest area 31.
  • the stroposcope lamp 29 takes over the detection of the height of the coating knob from the substrate 1, while the stroposcope lamp 30 monitors the areal extent.
  • the coating knob 28 changes in height or areal extent, this is recognized by means of the latching field 31, since for example with an increased areal extension of the coating knobs 28 at least partially falls out of the latching field 31. In this case, the corresponding operator can take the necessary precautions to reduce the amount of coating material applied.
  • the arrangement according to FIG. 9 also serves a similar purpose.
  • the substrate 1 is guided after the coating gap 8 over three deflection rollers 32, 33 and 34.
  • These deflection rollers 32, 33 and 34 have axle journals 35, which are held in corresponding bearings 36.
  • These bearings 36 at least partially consist of flexible supports 37 which are approximately U-shaped.
  • a strain gauge 38 is placed on these supports 37. If the journal 35, as shown in FIG. 10, presses against the support 37, the latter yields, whereby a connecting leg 39, on which the strain gauge 38 rests, is curved. As a result, this strain gauge 38 is stretched, this strain being detected and monitored by a corresponding control unit (not shown). If, for example, the weight of the coated substrate 1 increases, the deflection roller 32 tries to move in the direction x. As a result, the journal 35 increases its pressure on the support 37. This bends, this bending being transmitted to the strain gauge 38.
