Description

The invention relates to the production of a pyramid-shaped decorative element from four individual elements Side surfaces with face veneers, the joints of which are brought together to fit on all four edges

In addition, the four times identical course of the wood grain with the pyramid base edge an unbound laying direction, in particular to form a grid with half or double rectangular size allows

There are already processes for the production of pyramid-shaped decorative elements by compression molding very weak veneer panels have become known, with which the face veneer in one direction over runs all four side faces

This creates a pyramid-shaped decorative element that, depending on the shape, does not match A matching appearance is achieved especially since the tip is closed with a cover cap. Neither can other pitch of the element can be produced without having previously built a suitable device (mold) to have.

The present invention is based on the object of avoiding the disadvantages outlined above and a pyramid-shaped decorative element made up of four individual side surfaces with face veneer. whose thrust as all four edges are brought together appropriately, and that there is no significant waste

Such a process is of great practical interest: because it arises in spite of the complicated Shape apart from bleed and remainder no further noteworthy waste from the previously largely refined surface.

This object is achieved according to the invention in that (according to the previous outline of the in the desired size to be manufactured pyramid-shaped decorative element) four plates of equal width, with four If possible identically drawn veneers are veneered in such a way that two panels with one (front) side and two panels are covered with the other (back) side of the veneer that from each of the four panels only a side surface is cut for one and the same pyramid element and that these four side surfaces are joined together in such a sequence that results from the sequence of mutual veneering The width of the panels depends on the uncut surface width a * side panel plus allowance for sawing exactly by width after veneering the length of the panels according to the existing veneer length.

After veneering, the panels are cut to width in full length, taking care to ensure that this is the case that the same veneer grain spacing is maintained on all four panels from the cut edge. The length cut is also made on all four panels with the same dimension from the start of the veneer and from the marked veneer image side is carried out for one and the same pyramid element

Then the surface processing is started by sanding the surface in full length of the veneer (Wood sanding), primed and then the base lacquer sanding is carried out. Mutual cutting the side parts (Fig. 4) is carried out with the conventional sawing devices.

The side parts to be cut off alternately can be numbered consecutively or, in order to save time, the In order to be stacked. With the latter method, the subsequent operations (Grooves or dowel holes drilling the diagonal glue edge) no mix-ups occur. Of each Plate is made an extra stack and marked with plate numbers I - IV (Fig. 4)

The edges are cut to the element size at a 90 ° angle on the glued element, then veneered and Depending on the intended use, grooved for laying in a composite or when used as a Individual element cut horizontally into a support surface (Fig. 2). Then the edges are sanded and plastered together with the diagonal glue joint edges. The element is then finished painted

The invention is illustrated, for example, in the following figures. It shows

F i g. 1 the top view of the glued body with the section AB , the edges being indicated or shown uncut,

2 shows the top view of the finished body with the section AB with the element for laying in the composite is shown,

3 shows the possibility of laying two different sizes in a composite,

F i g. 4 the two differently veneered panels with Veneer grain design and the cord guide for separating the side parts.
