Definitions

  • the invention relates to a device for silting, stretching and drying Leather or similar flat materials such as Skins, furs and the like.
  • DE 38 33 068 describes a device as the closest prior art known in which the leather pieces in a gap between a slidable Carrying surface and an elastically stretchable membrane stretched under vacuum become.
  • the application enables a rigid support made of highly thermally conductive material combined stretching and drying machine, whereby the evaporated leather moisture due to the relief-like structure of the membrane, which is equipped with a suction device is connected, is discharged.
  • This device affects the leather acting pressure forces despite the sliding surface against the stretching force Act.
  • the resulting resistance (friction) prevents the optimal Carrying of the leather, as well as its all-over even stretching and limited the achievable dimensional gain.
  • the elastic membrane is heavily stressed; their consequently limited lifespan leads to an increase in operating costs the machine.
  • this device is only suitable for the treatment of hides with low water content (approx. 25%); it is not suitable for very wet leather.
  • Vacuum dryer systems are also known which also have very wet leather dry. Excess water is removed manually here. The However, leather is only dried - not stretched at the same time - and it is shrinking.
  • the object of the invention is to provide a device which is high Frictional forces when stretching the leather under vacuum are eliminated in that the leather support surface is formed by elements, which the leather as well as the Take the pressure device over the entire surface without frictional resistance to the support surface, thereby optimally enlarging its area, and which is also able to stretch and dry very wet leather at the same time and if necessary beforehand harnessen.
  • the object is achieved in that a smooth, slidable, Contact surface, which consists of highly heat-conducting material and through Thermal energy is heated by means of hot water, oil or another medium, movable slats are arranged, which with a drive device for circular extension from the center to the outside around a fixed point are connected.
  • These fins form the actual stretching tool
  • the pressure device arranged one above the other which consists of a plate stretchy material with channels, knobs, perforation and the like for drainage the leather moisture exists, mainly has a fixation function.
  • the pressure device can also consist of a solid, non-stretchable plate, the Surface with channels, perforation and the like for removing the leather moisture is provided.
  • a second slat system becomes a mirror image of this attached, so that between the two outward extending slat systems Leather is stretched and fixed by the fixed pressure plate.
  • the device depicted in FIG. 1 works with a device on the support surface (AF). attached slat system (LM1) and a stretchable membrane (M) existing pressure and stretching device, which are arranged one above the other.
  • the leather piece (L) is placed on the slats (LM1) of the support surface (AF).
  • a vertical movement brings both parts together and the gap by means of a seal (D) which is located on the edge of the stretchable membrane (M) or the contact surface (AF) is sealed.
  • the gap space on one Vacuum source (VQ) is connected, is evacuated.
  • the Slats (LM1) e.g. by a circular movement around a fixed bolt, by means of a drive device (AV), e.g. mechanical, hydraulic or pneumatic, extended and take the leather piece (L) on top.
  • AV drive device
  • the excess water is clicked out, wrinkles smoothed and the surface stretched evenly.
  • the one formed by the stretchable membrane (M) Pressure device (AD) partly follows the path of the slats, but is by moved its own stretching device.
  • the extending slats (LM1) lay one smooth, heated by heating (H) contact surface (AF) made of high quality metal free.
  • the stretched membrane (M) fixes the stretched leather piece continuously (L) on the contact surface (AF), which is affected by the heat at the same time is dried.
  • the resulting moisture is channeled, nub-like Surface, perforation and the like, which either in the metal plate of the Contact surface (AF) or in the membrane (M) are removed.
  • the vacuum is released.
  • the device shown in FIG. 2 operates on the same principle; the Pressure device (AD) is, however, by a solid, non-stretchable plate (P), on which a second lamella system (LM2) is attached in mirror image.
  • the leather piece (L) is replaced by the simultaneous one Extending both slat systems (LM1, LM2) stretched, the heated support surface (AF) is exposed and the firm, non-stretchable plate (P) fixes the leather (L).
  • Fig. 3 shows an example of the solution of the lamella system (LM1, LM2), where the circular movement of the slats around the fixed point is shown.
