Definitions

  • the invention relates to a method for applying liquid, pasty or plastic substances, in particular thermoplastics, to a substrate, the substance being melted, heated and applied to the substrate by a perforated cylinder to which it adheres over a distance before it is withdrawn, and a device therefor.
  • Such a method and such a device is known from DE-OS 36 38 307, the nozzle mouth in the interior of the metal cylinder being followed by an air nozzle which forms a nozzle gap bounded by lips towards the metal cylinder. Furthermore, cooling or heating sections are arranged outside the metal cylinder before the substrate passes through a pair of calender rolls.
  • the object of the present invention is to ensure an improvement in the application of the coating substance and in the handling of the coating head when the device is switched off.
  • the solution to this problem is that the distance between the axes of rotation of the counter-pressure roller and cylinder is smaller than the sum of the radii, that the counter-pressure roller consists of a flexible material and that a contact surface of the coating head to form the coating gap has a curvature, the radius of which is approximately that of the cylinder.
  • a vacuum pump is switched on in the feed line for the substance.
  • This vacuum pump is preferably connected to the coating head via a three-way valve and then started when the device is switched off. This then empties the coating head and there is no dripping of the substance.
  • the coating head consists of sub-segments which are connected to one another.
  • the connection can be made, for example, via appropriate tie rods.
  • the width of the coating head is determined or changed, and coating in strips is also possible in that one or more sub-segments do not have an orifice gap for a coating substance.
  • a substrate 1 to be coated runs into a coating gap 2 from a supply roller (not shown in more detail).
  • This coating gap 2 is formed by a perforated cylinder 3, in particular a metal cylinder, and a counter-pressure roller 4.
  • the counter-pressure roller 4 is made of elastic material.
  • the distance a between the axis of rotation A of the counter-pressure roller 4 and the axis of rotation B of the cylinder 3 is smaller than the sum of the two radii r 1 and r 2 .
  • the elastic counter-pressure roller 4 is deformed in the region of the coating gap 2 by the pressure of the cylinder 3. This deformation is of course also given if, in the narrower sense, no coating gap is formed between cylinder 3 and roller 4 without a substrate.
  • a coating head 5 presses against the inner surface 6 of the cylinder 3 from the inside of the cylinder 3.
  • a contact surface 8 is formed on both sides of the opening gap 7 around an opening gap 7 of the coating head 5, this contact surface facing the inner surface 6 having a curvature with a radius r 2 .
  • This arrangement creates an area of the coating gap 2 which is sealed by the contact surface 8 and the counter-pressure roller 4. For example, sealing lips around the mouth gap 7 are unnecessary.
  • the substrate 1 After the coating gap 2, the substrate 1 still runs a certain distance on the cylinder 3, then lifts off and loops around a roller 9.
  • a main chamber 15 is connected upstream of the orifice gap 7 in the coating head 5 and is connected via a corresponding connection channel 16 or feed line 17 to a source (not shown in more detail) for molten coating material.
  • a three-way valve 18 is to be switched on in line 17, via which line 17 is alternately connected to the coating material source or to a vacuum pump 19 can.
  • the three-way valve switches over to the vacuum pump 19, via which excess coating material is withdrawn from the main chamber 15 or the mouth gap 7.
  • a simple cylinder, for example, in which a piston forms a working chamber can also be used as the vacuum pump. By pulling back the piston, the working space is enlarged and coating material is sucked in. When starting up, this material is first pressed out. This effectively prevents coating material from dripping out of the mouth gap 7.
  • the coating head 5 is constructed in several parts.
  • the coating head 5 consists of the sub-segments 5a, 5b and 5c. These sub-segments are connected to one another by means of corresponding tie rods and, if necessary, sealed off from one another. In this way, the width b of the coating head 5 can be determined and changed.
  • a sub-segment, for example 5b may not have an orifice gap 7, so that coating is carried out in strips.
