Definitions

  • the present invention relates to a method for the production of panels with connection profiles, in particular for floor panels.
  • connection system under the name "click profile" has become known.
  • the connection system is based on the edges of the plates arranged connection profiles, which are initially hooked into one another and can be locked by a pivotal movement of the plates in a horizontal plane.
  • other connection systems and mounting techniques have become known, see eg DE-102 53 236-A1 or U.S. 3,187,612 ,
  • connection profiles are carried out by a machining, in particular profile milling, the side areas already tailored panels.
  • a plate-shaped starting material is cut into individual plates by a cut, for example with a circular or band saw.
  • the plates have a suitable oversize, wherein a predetermined part, in particular the edge region, is fed to a further processing step. Due to the complex production of the connection profile, a not inconsiderable part of this edge region must be milled off, so that this is accompanied by a considerable waste of material.
  • this object is achieved by a method according to claim 1.
  • the material consumption can be reduced, since even when separating the plate-shaped starting materials, the later-introduced profile is taken into account.
  • the later-introduced profile can be milled by an appropriate profiling of the tool, ie the saw or the milling cutter, a rough contour.
  • the proposed method is suitable as a preparation for introducing the actual profiling, for example, the "click profile" in the edge regions of the plate-shaped material.
  • the recesses are rectangular recesses.
  • Such recesses can be in a simple manner with conventional milling or cutting tools, such as circular saws bring. Conceivable, however, are of course also specially profiled circular saw blades or a conventional router whose tool rotates perpendicular to the plate-shaped base material.
  • the recesses are aligned parallel to each other.
  • Such an alignment of the recesses is particularly suitable for the production of connecting profiles, since they extend substantially uniformly along the side edge of the respective plate.
  • none of the side surfaces of the rectangular recesses lie in a plane.
  • a corresponding example is in the Fig. 2 displayed.
  • the material consumption can be further reduced, the farther the offset of the recesses, wherein the distance between the recesses can not be increased infinitely.
  • An important influencing factor here are the material properties and the profile shape of the plate-shaped starting material used, it being particularly necessary to ensure that the plate-shaped starting material will break exactly along the intended breaking point.
  • two side surfaces of the rectangular recesses lie in a plane.
  • a Such position of the recesses is schematically in the Fig. 1 If two side surfaces of the recesses are aligned as proposed here, no predetermined breaking point is present, so that the plate-shaped starting material without breaking of the predetermined breaking point requires a first plate and a two plate decays.
  • the shape of the recess is approximated to the preciselyfräsenden profile.
  • the waste i. the waste of material can be further reduced.
  • the recess can be regarded as a kind of pre-processing stage for the profile to be finally cut, for example the "click profile". The more the cutout approaches this finishing state, the lower the cut can be.
  • a predetermined breaking point between the first recess and the second recess is provided, which must be separated to separate the plate-shaped starting material into a first plate and a second plate.
  • a predetermined breaking point remains between the recesses after the introduction of the recesses. Accordingly, after the breakage of the predetermined breaking point, there is a kind of projection which can be used for forming into the desired profile.
  • the predetermined breaking point extends between the bottom region of the first recess and the bottom region of the second recess. Such a predetermined breaking point advantageously results from the recesses. It is not necessary to take further measures, such as perforations or the like.
  • the predetermined breaking point extends approximately parallel to the surface of the plate-shaped starting material. Accordingly, there are advantageous projections that can be further processed to the desired profiles, such as click profiles.
  • Fig. 1 is a schematic representation of a manufacturing process, in particular a first manufacturing step outlined. For illustrative purposes, it is a cross-sectional view of a plate-shaped starting material 1.
  • the result is a first recess 3, which can be configured, for example, depending on the saw, as a rectangular recess 3.
  • any tool is suitable which is suitable for producing cuts or recesses in plate-shaped starting materials 1, for example HDF boards, ie also a milling cutter or a similar tool.
  • This second recess 4 may be configured rectangular. It can be seen that the recesses 3, 4 are not complete cuts, that is, the plate-shaped starting material is not divided into two parts by a recess alone.
  • the recesses 3, 4 are arranged offset, whereby the waste can be minimized, since on the one hand a separation of the plate-shaped starting material in a first plate 6 and a second plate 7 is possible, but in the region of the recesses 3, 4th , Preferably below and laterally or above and laterally, a proportion of material remains, which can be further processed.
  • the HDF consumption in the floor area can therefore be reduced by at least 1%. You just have to eliminate the saw cut. It's easy to do that by scratching the plate from above and from below, taking into account the (click) profile. It may also be possible to make the saw wider (ideally with a profile) so that it takes on the function of the pre-cutter.
  • a predetermined breaking point 12 can be seen here very clearly, which extends between the bottom regions of the recesses 3, 4.
  • the plate-shaped starting material can be broken after the inventive processing by the offset saws 10, 11, wherein the plate-shaped starting material will break at the predetermined breaking point 12.
  • the advantage of the proposed method is also very clear.
  • the indicated, possibly laterfräsenden in a subsequent process step and here already indicated profiles 8, 9 are considered.
  • the profiles 8, 9 can quasi close together, whereby the consumption of plate-shaped starting material, in particular HDF plate can be further reduced.
  • FIG. 3 the position of the recesses to be introduced in a plan view of a plate-shaped base material 1 to recognize well, in particular their position and orientation transverse to the longitudinal direction of the plate-shaped base material 1.
  • the illustration is of course only exemplary and the recesses 3, 4 may in principle have any orientation.
