Definitions

  • stenter dryers are most effective because the leather is pre-tensioned on the stenter before the drying process.
  • One of the major disadvantages is that the prestressing is carried out manually using a large number of so-called leather clips, since the leather has a geometrically undefined outline.
  • the invention eliminates this disadvantage in such a way that elastic air-impermeable foils are arranged from both sides of the leather, the space between the leather and the two foils is connected to vacuum, and then with forces which are predominantly in the plane of the two foils , the area of the foils is enlarged.
  • Thermal energy is added to the leather that is between the foils, e.g. by infrared radiation of the foils, by means of contact heat or the damp leather is heated by means of radio frequency energy.
  • the effect of the forces on the foils is variable during the treatment of the leather, e.g. repeated pulsating or oscillating effects.
  • FIGS. 1-3 Exemplary designs of the devices that work according to this method are shown in FIGS. 1-3.
  • the device shown in FIG. 1 works with 2 foils 2 and 3, which have a round shape 10.
  • the leather 1 is placed between the two foils 2 and 3 (for example, the entire upper part of the device is moved away with the foil 2 upwards or to the side). Then both slides 2 and 3 are moved together again.
  • the space 4 is sealed with the help of the seal 7, which is located near the edges 8 of the foils.
  • the room 4 is connected to a vacuum 5.
  • the atmospheric pressure now presses from the outside onto both foils 2 and 3 and thus onto the leather 1.
  • Ropes 15 are fastened to the edges 8 of the two foils 2 and 3 and are fed centrally to a hydraulic cylinder 14 via deflection rollers.
  • a rope system is used for both foils 2 and 3.
  • the ropes 15 exert a force on the edges 8 of the two foils 2 and 3 in such a way that the area of both foils is increased. Since the same If the foils are pressed onto the leather 1 from both sides with the aid of atmospheric pressure, the leather follows the expansion of the two foils and the area of the leather increases. It is possible to repeat this process as required. When the foils return to the starting position, the vacuum is released. If the films are pulled apart repeatedly, the vacuum is built up again. When the leather dries, thermal energy is supplied to the leather, as in this arrangement, for example, by means of irradiation with infrared radiators 9.
  • the foils 2 and 3 have a square shape 11.
  • the force itself is exerted on the foils by means of hydraulic cylinders 14 which act directly on the edges of the foils. Since the hydraulic cylinders 14 only act on the lower film 3, the upper film 2 is mechanically carried along with the film 3 at the edges 8 when the film is moved apart.
  • the workflow is the same as for the device in FIG. 1.
  • FIG. 3 shows an arrangement in which the foils 2 and 3 are designed as conveyor belts 12 and 13.
  • the leather 1 is placed on the conveyor belt 13 and spread out and then transported into the space 4 by means of the movement of both conveyor belts. In this position, the leather is sealed with the help of seals 7 between the two bands, the space 4 is connected to vacuum 5. With the help of hydraulic cylinders 14, both bands are stretched both in the longitudinal direction and increased in width by the action 6 on the edges 8.
  • the leather 1 is either transported back out of the space between the two conveyor belts or continuously transported forward. With this arrangement, too, it is possible to supply thermal energy to the leather by means of radiators 9 or the room 4 can lie in an electrical high-frequency field.
