Description

DESCRIPTION

The present invention relates to a method for making superficially worked laminated wood tiles, as well as tiles made with the method.

Laminated wood elements have been known on the market for several years now, mostly used in furniture.

Laminated wood, obtained by juxtaposing, interlocking and gluing one to the other strips cut from solid wood, is mainly used for the construction of table tops, furniture tops such as modular kitchens.

The alternation of strips with shades of different color from each other obtains valuable aesthetic effects so that in recent years the market linked to these products has had a rapid expansion.

From a structural point of view, the laminated wood product is qualitatively better than the normal solid wood as the cut into strips and the subsequent reassembly to create the laminated semi-finished product from which the finished product is then obtained means that the tensions inside the material due to the reciprocal interaction of the fibers that constitute it.

Consequently, laminated wood tops are certainly to be preferred over normal solid wood tops because they are not subjected to deformations caused by the aforementioned tensions over time.

The success on the market of glulam products has pushed the manufacturing companies to expand the range of products more and more looking for alternatives to the previously mentioned "horizontal" applications in which the fundamental need was to create perfectly flat and level surfaces, studying therefore "vertical" applications such as partition walls, wall cladding, window frames, etc ..

In these products, however, there is very often the need to create surface decorations in order to further improve the aesthetic effect and attempts made so far have not led to satisfactory results as the surface processing by removing the material obtains the undesirable effect. to alter the balance of internal tensions in the product with consequent deformations and unacceptable aesthetic consequences.

This is then particularly amplified in the case where the construction of the structure is envisaged by the composition of a series of tiles joined to each other at the edges.

The main aim of the present invention is therefore to provide a process for making superficially worked laminated wood tiles which solves the above-mentioned drawbacks in the known art, in particular for making tiles which are not subject to deformation with the passage of time.

Within the scope of the aforementioned task, a consequent primary object is to provide laminated wood tiles for which the construction of dividing walls or similar vertical structures can be proposed.

Another important object is to provide a tile which can be easily combined with others to form said dividing structures.

Another object is to provide a method which can be carried out with tools

use

These and still other purposes, which will appear more clearly later on, are achieved by a process for making superficially worked laminated wood tiles which consists of:

carry out surface machining on both faces of the tile by removing material such that there is symmetry with respect to a plane parallel to the faces passing through the center line;

immediately after the aforementioned processes, treat the tile surface with a paint suitable to close the pores of the wood.

Advantageously, the laminated wood panel is characterized by the fact that both faces are machined by material removal with symmetrical machining with respect to a plane parallel to the faces passing through the center line.

Further characteristics and advantages of the invention will become clearer from the detailed description of the operating steps of the process and of the mold made with it, illustrated by way of example, but not limiting its scope, in the attached drawing tables in which:

fig. 1 is a perspective view of a first mold;

fig. 2 is a side view of the mold

fig. 3 is a perspective view of a second mold with an interlocking strip;

fig. 4 is a perspective view of a portion of a panel made with tiles according to the invention.

With reference to the aforementioned figures, a process for making superficially worked laminated wood tiles provides a first phase in which surface machining for material removal (e.g. milling) is carried out, for example with numerically controlled pantograph machines. there is symmetry with respect to a plane parallel to the faces passing through the center line.

Referring in particular to figs. 1 and 2 a mold worked in this way is indicated by the reference number 10 and has on both faces 11 and 12 channels, 13 and 14 respectively, obtained by chip removal to create mirror designs.

This in particular has the effect of balancing the tensions generated in the material by the individual processes.

A subsequent phase of the procedure foresees, immediately after the machining for chip removal, the surface treatment of the mold with a wood varnish suitable to close the pores.

In this way, the complete separation of the material from the atmosphere is obtained from the negative effects that contact with it can bring.

Another example of a mold, always indicated with the same references, is illustrated in fig. 3 and is characterized by decorative designs different from the previous one made in any case with the same procedure.

The mold 10 has a milling 15 made perimetrically on the entire edge that constitutes the female of a male-female joint in which the male is constituted by a strip 16, made of wood, plastic, metal.

The strip 16, having a length substantially equal to one side of the mold 10, can be inserted into the milling 15 and can therefore be hidden between two consecutive molds 10.

The width of the strip 16 is at most equal to the sum of the depth of two millings and the thickness is such that the insertion takes place substantially without play.

The composition of several tiles 10 with the strips 16 is suitable for making panels, which, supported by perimeter frames 17 within which they are composed, create vertical structures such as partition walls, wall coverings, etc.

In alternative embodiments, instead of the strip 16, a cross-section profile can be provided, not shown in the figures, which can be inserted with two wings coplanar between the tiles so that the other two wings orthogonal to the previous ones are visible from the outside.

In practice it has been found that the intended aim and objects of the present invention have been achieved.

In fact, with the implementation of the method according to the invention, the production possibilities relating to laminated wood are extended to the sector of vertical structures worked on the surface.

The process can be carried out with usual machines for the removal of numerically controlled material and with known painting machines.

The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept.

Furthermore, all the details can be replaced by other technically equivalent elements.
