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melted, heated and applied to the substrate by a perforated cylinder to which it adheres over a distance before it is withdrawn, and a device therefor.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. It has been found in practice that at different temperatures of the coating substance, a different pull must be exerted on the substrate in order to lift the substrate from the perforated metal cylinder.
  • the object of the present invention is to significantly improve the temperature control for the coating substance and also 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.
  • a method of the above leads to the solution of this task.
  • the adhesion is determined, for example, directly or indirectly via the length of the adhesion distance and / or the peeling force and / or the peeling angle between the cylinder and the substrate, the tension of the substrate being kept constant.
  • this pressure or the pulling force can now be measured directly. If the pulling force to be increased increases, the heating elements are to be addressed and the heat output is to be increased by means of a corresponding control device.
  • the roller changes its position depending on the adhesion of the substance to the cylinder. If a corresponding range of the change in position is exceeded, a control unit should also be addressed here which regulates the heating elements until the roller returns to its starting position.
  • the return is preferably carried out by a counterforce, which is exerted on the roller, for example, by a corresponding helical spring.
  • the infrared radiation has the advantage that the heat is absorbed by the substrate or the cylinder without the region between the source and the cylinder being heated. This also improves lifting of the substrate from the cylinder.
  • the distance between the axes of rotation of the counter-pressure roller and the cylinder is smaller than the sum of the radii, that the counter-pressure roller also consists of a flexible material and that a contact surface of the loading head has a curvature to form the coating gap, the radius of which corresponds approximately to 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 have no opening 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 buzzer 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 of approximately the 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 wraps around a roller 9.
  • the area of the substrate 1 lifting off from the cylinder 3 is illuminated according to the invention with an infrared light from a corresponding source 10, to make lifting easier by heating the lifting area.
  • the roller 9 is designed as a dancer roller, ie its axis of rotation C can be shifted in the direction x.
  • This shift in the direction x into, for example, the position of use shown in dashed lines takes place against a counterforce, by means of which an attempt is made to move the roller 9 back into the position of use shown in solid lines.
  • the coating applied to the substrate 1 through the opening gap 7 and through the cylinder 3 is too cold, the adhesion with which the substrate adheres to the cylinder surface increases.
  • the roller 9 yields to this higher adhesion, so that it is displaced in the direction x towards the position of use shown in broken lines.
  • This shift is transmitted via a corresponding line 11 to a control unit 12 which emits a control signal via line 13 or corresponding branch lines to heating elements 14.
  • the heating elements 14 are only shown schematically around the coating head 5, but a different assignment of the heating elements 14 is also conceivable.
  • the coating substrate can be heated on the way to the coating head 5 or heated again after the substrate has run out of the coating gap 2.
  • 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 can alternately be connected to the coating material source or to a vacuum pump 19.
  • 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 formed 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.
