  • an extrudate or covering material is created which can be used to produce reliable and reproducible results in a wide range of applications.

  • the shape as a pourable good, the portioning and packaging is relatively simple.
  • the extrudate is extruded in granular form or that the granules downstream by at least one of the extruding Working step is obtained.
  • granulation by means of a hot air deflection process, in which a hot extrudate leads to the formation of granules by the supply of an air flow in the region of the outlet opening.
  • the granulation is carried out only on the basis of a non-granular body, for example, by breaking or cutting a plate-shaped body in granular form.
  • the melting temperature of the matrix material is in a temperature range of 150 ° C to 340 ° C, wherein it is further advantageous if the upper limit of the temperature range of the melting temperature of the matrix material is less than 200 ° C is.

  • the filler is a solid which is preferably powdery.
  • the processing of the solid, especially in the production of the extrudate, is particularly simple.
  • the filler is present as a spherical body, as a rod-shaped body or as platelets or as a combination of the aforementioned geometries.

  • FIG. 1 shows two perspective views of the device according to the invention 1.
  • the device 1 has a first portion 3 and a second portion 4, which are separated by a thermal separating element 6.
  • the cross-sectionally U-shaped device 1 has in the first section 3 an outlet opening 2 (only rear side of the outlet opening visible), which is designed to deploy a cover material from the web of the U-shape to the two legs of the U-shape ,
  • the two legs of the U-shape are spaced apart so that between them a plate can be added, the edge of which then cover material from the outlet opening can be acted upon.
  • Fig. 2 shows the interaction of an extruder 8 with the device 1.
  • the extruder 8 is attached with its extrusion die at the back of the outlet opening 2, so that extruded from the extruder 8 covering material in the direction of the two legs of the U-shape from the outlet opening 2 can be dispensed.
  • Fig. 3 shows a further side view of the extruder 8 provided with the device 1, wherein in the space formed by the legs of the U-shape of the device 1, a plate 7 has been received at an edge region.
  • the two legs of the U-shape of the device 1 lie with their mutually facing sides on each of a flat side of the plate 7, so that an edge of the plate 7 of the outlet opening 2 of the device 1 faces. From the outlet opening 2 exiting cover material is therefore guided to the edge of the plate 7, at the same time a flow of the cover material on the flat top or bottom of the plate 7 is prevented by a flush receiving the plate in the two legs of the U-shaped device. Only a flow of the cover material in the longitudinal direction of the edge of the plate 7 may occur and is partially desired.
  • Fig. 4 shows a perspective view of the already in Fig. 3 explained side view. It can be seen the two sections 3, 4 of the device 1 and the thermal separating element 6 which is sandwiched between the two sections 3, 4 and serves to thermally decouple the two sections 3, 4 from each other.

For heating, the waste heat produced by the extruder can be used.
  • the arrangement of the device 1 with the extruder 8 is. With respect to the plate 7 is moved so that from the device 1 freshly leaked cover material with the second portion 4 of the device 1 comes into contact and is cooled thereby. This cooling process ensures the transition of the cover material in a non-flowable state.
  • the second section 4 is connected to a cooling device (not explicitly shown) which the temperature of the second section 4 keeps below the temperature of the first section 3. Accordingly, the movement is carried out so that the cover material emerging from the heated section 3 is cooled with the cooled second section 4.
  • Fig. 6 shows a second way to apply the peripheral edge of the plate 7 with cover material. It is now not the arrangement of the device 1 and extruder 8 is moved, but the plate 7. The operating principle for applying the cover material to the edge of the plate 7 is identical to that of the FIG. 5 ,

  • the two openings 51, 52 are connected in the second section 4 with a conduit which is adapted to cool the second section 4.
  • Fig. 8 is a further illustration of the device 1 according to the invention, in which the outlet opening 2 is optically highlighted by a black circle.
  • the first section 3, in which the outlet opening 2 is arranged, and the second section 4, which is separated by the thermal separating element 6, can also be seen.
  • This section likewise has the inlet and outlet openings 51, 52 for introducing or discharging a cooling fluid, which flows to the outlet Cooling of the second section 4 is used.
