  • the upper pressing part 8 is moved upward, as in Fig. 11 is shown.
  • the mandrel 13 is retracted so far that the tip no longer or only slightly protrudes into the mold cavity 10. Subsequently, the solidified support plate 2 of the pressing device 7 or the mold cavity 10 can be removed.
  • a plate 1 with the upper layer 3 and / or the lower layer 6 can be produced instead of in the Fig. 9 to 11 embodiment shown in the pressing device 7 not only a support plate 2, but also a plate 1 with the upper layer 3 and / or the lower layer 6 can be produced. If both an upper layer 3 and a lower layer 6 are provided, first the lower layer 6 is inserted, on which then the not yet compressed mat made of nonwoven fabric is placed. In turn, the upper layer 3 is placed on this. The compression of the upper and / or the lower layer 3, 6 with nonwoven material, which subsequently forms the carrier plate 2, then takes place during the compaction in the in Fig. 10 illustrated state.
  • Fig. 12 is a plan view of a lower pressing part 9 of a pressing device 7 is shown, with which a base plate with 16 individual plates 1 can be produced.
  • the lower pressing part 9 has a series of contouring means in the form of profilings 14, which are longitudinal and transverse projections which ultimately predefine the rectangular plates 1.
  • the profiles are at least partially adapted to the shape of the locking contour, that is, the spring 4 and / or the groove 5 of the plates 1.
  • the profiling provided there does not necessarily correspond to the profiling on the opposite pressing part, but are adapted to the top-side profiling of the spring 4.
  • the illustrated embodiment of the lower pressing part 9 is only an example. Basically, the lower pressing part 9 may have any number and shape of shelves for plates 1.
  • a continuous working pressing device 7 is shown.
  • This has as upper and lower pressing part 8, 9 in each case a roller, which in each case has a profiling 14 in the present case.
  • the profiling 14 which represents the shape of a circumferential projection with an on-demand precontouring in adaptation to the profile of the tongue and groove joint, can basically also be omitted, so that only smooth, cylindrical rollers are used.
  • Fig. 13 also schematically shows the type of solidification.
  • the pressing device 7 and the rollers is supplied with a binder impregnated with a thermoplastic fibers or non-woven material which is compacted for solidification.
  • a solidification takes place under a predetermined pressure and a predetermined temperature, with a degree of compaction of between 4: 1 and 5: 1 also being achieved here.
  • Fig. 14 is the after the procedure off Fig. 13 produced carrier plate 2 shown schematically, which has been separated after manufacture by the pressing device 7 of the produced strand of material It is understood that according to the method Fig. 13 individual support plates 2 but also base plates, which are then divided into individual plates 1, can be produced. Incidentally, it is also possible in the continuous process, not only to produce the support plate 2 via the formed as a rolling device pressing device 7, but also the plate 1 as such. In this case, the upper layer 3 and / or the lower layer 6 then passes directly to the pair of rollers 8, 9, or else the individual layers 3, 6 are fed in after the pair of rollers and before separation of the base plate / plate 1 / carrier plate 2.
  • carrier plate 2 can be used in principle as a furniture component, which is then provided on the upper side with the upper layer 3 and the lower side with the lower layer 6 and can also be provided on the edge with corresponding layers
  • a carrier plate 2 is shown, which is processed on the edge side and are provided on the corresponding locking contours via a spring 4 and a groove 5.
  • the upper layer 3 and, on the underside, the lower layer 6 can then be provided on the upper side of the carrier plate 2.
  • a paint coating is provided as a layer on the top and bottom sides and edge edge side.
  • Fig. 16 is a front view of the pressing device 7 from Fig. 13 shown. Visible are the two outer profiles 14 and the intermediate central profiling 14 on the rollers. Although this is not shown in detail, the profiles 14 are not V-shaped at their ends, but at least partially correspond to the contouring or the profile of the tongue and groove joint on the top and bottom of the plate. 1
  • Fig. 17 is different from the one in Fig. 16 in that 14 additional transverse profiles 15 are provided on the formed as rollers pressed parts 8, 9 in addition to the longitudinal direction in the direction of rotation profilings 14, which ultimately define the plates 1 or support plates 2 of a base plate to be produced. Also, the transverse profiles 15 are adapted at least partially on its upper side to the profile or the contour of the locking contour of the plate 1.
  • Fig. 18 shows a transverse view of the pressing device 7 Fig. 17 .
