Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to wooden tiles and methods of manufacturing wooden tiles.

Wooden tiles have been used as cladding materials, especially flooring materials. For many years now, the availability of logs of good quality meant that considerable wood waste was produced during manufacturing without any problems, and the tiles were therefore unnecessarily thick. Today, logs are very scarce and therefore expensive. Therefore, to solve these problems, the thickness of floor tiles is generally reduced, and the thickness of floor tiles manufactured today is about 6-7 mm.

Relatively thin tiles have not been readily available because it is uneconomical to manufacture tiles by conventional methods.

However, in the conventional well-known floor tiles with a thickness of less than 6 mm, the veneer with a thickness of 1 to 2 mm is replaced by plywood with a thickness of at least 1.5 mm to produce laminated wood tiles. or bonded to an inexpensive wooden backing board such as chipboard. While this method can reduce costs slightly, the quality of the tiles is considerably reduced and the useful life is relatively short.

In another attempt to reduce tile thickness, the tile is provided with a top layer of sub-1-layer thin veneer. -1 It is manufactured by bonding a substrate having a lined transparent synthetic resin layer on its lower layer. However, this method is quite expensive and tiles produced in this way do not have the natural warmth that natural wood tiles have.

A previously known method of overcoming these problems has been to manufacture wood tiles by sawing sheets of wood from lumber. The sheet lumber is then cut into a number of individual square blocks and adhesive is applied to the edges of the blocks. Next, the Iff sticks are brought into contact with each other by juxtaposing the 1111 surfaces on the side surfaces in several determined patterns to join them together.

The disadvantage of such a method is that it is generally not practical to produce lumber with a thickness of less than 6.2 mm. A significant amount of wood was scrapped by the sawing action, and the yield was poor as a result of the mismatch between the shape of the log and the straight sawing line required to obtain the desired thickness of the log.

Additionally, cutting wood with a saw results in the top and bottom surfaces of the cut notebook being a densely grained surface, resulting in a rigid, substantially inflexible and brittle surface. It becomes a final tile that is easy to use.

The aim of the invention is to provide a wooden tile which substantially eliminates these drawbacks.

Yet another object of the present invention is to provide a method for manufacturing wood tiles such that the wood tiles are highly flexible and durable.

According to an embodiment of the present invention, there is provided a wooden tile used as a floor covering material, which is made of a plurality of members formed from a sheet of wood cut with a knife and then joined together to form a tile. provided.

Preferably, the members are joined to each other by adhesive applied to the sides of the members before they are assembled into the tile. As another method, it is also preferable to join the members to the agates 1 and 2 without using an adhesive between them.

In a preferred embodiment of the invention, the tiles are made from teak and have a thickness ranging from 1.5 to 1Q mm.

The thickness of the tile is preferably 2.5 mm.

The member is formed to have a predetermined vertical and horizontal width, and it is preferable that the vertical width is longer than the horizontal width. Preferably, the parts are joined together with an adhesive, such as a urea resin adhesive. The shape of the tiles formed in this manner may be hexagonal, but square is preferred.

In another embodiment, the individual members are preferably joined to a cotton mesh, i.e. by applying an adhesive, such as a urea resin adhesive, to the lower major surface of the tile and attaching the cotton mesh to said F section. In another embodiment, a cotton mesh impregnated with adhesive may be applied to the lower major surface of the tile formed by a member conveniently held in a jig. good.

Wooden tiles constructed according to the invention have the following advantages:
It has a degree of flexibility that is unknown for wooden tiles today.

According to another embodiment of the present invention, the step of cutting a sheet of wood of a predetermined thickness from lumber with a knife, the step of cutting said sheet of wood into a plurality of members, and then the step of cutting said sheet of wood into a plurality of members, and then the step of cutting said sheet of wood into a plurality of members, and then cutting one side of the member into a plurality of members. It is an object of the present invention to provide a method for manufacturing a wooden tile, which comprises a step of forming a plurality of the members into one tile in a state where they are in contact with one side.

Preferably, the method of the invention includes the steps of applying an adhesive to the sides of the component prior to forming the component into a tile, and then curing the adhesive to enable the components to be joined together.

The method of the present invention alternatively includes the step of bonding the tiles onto the mesh without having an adhesive between the parts.

Preferably, the members are formed with a predetermined length and width, the length being longer than the width, and the members are arranged with respect to each other to form a square tile.

Preferably, the blade cutter for cutting the sheet wood from the lumber is a rotary lathe that makes perfectly round rotary cuts.

In other cutting machines, such as slicers, the cutting blade is parallel to the longitudinal axis of the wood round bar and inclined horizontally, perpendicularly, or transversely to the longitudinal axis of the round bar. You can also move in the direction you are moving. In yet another slicer, the cutting knife can also be moved in the longitudinal direction of the wood bar and parallel to the longitudinal axis of the wood bar. In this case, there are no coarse and dense grain surfaces on the sheet. However, during the process of cutting the sheet, the sheet is subjected to pressure and the wood fibers become flexible, thus making them suitable for use in wooden tiles according to the invention.

The type of adhesive used to adhere the individual parts together or to secure the parts onto the mesh is preferably a urea resin adhesive, although other suitable adhesives may be used.

Once the bonding adhesive has cured or hardened, the individually assembled tiles are placed side by side between the platens of a hot press, and then a pressure of approximately 10 metric tons/ft2 is applied to the tiles at room temperature for approximately 3 minutes. This can be achieved by giving

Embodiments of the invention will be described by way of example with reference to the drawings.

In particular, with reference to the wooden tiles shown in Figures 1 and 2, the tiles are square and are joined together along their abutting edges by a suitable adhesive such as a urea resin adhesive. It is assembled from a number of independent wooden fingers 1.

In said tile, finger 1 forms a block with five parallel juxtaposed fingers;
Each block is arranged such that the longitudinal direction of the fingers forming each block is orthogonal to the longitudinal direction of the fingers of the adjacent block. In this method, 16 blocks are juxtaposed and connected to each other to form a tile, as shown in FIG.

FIG. 2 is a partial side view of the tile viewed from the direction of arrow A in FIG. Although not shown in FIG. 2 for clarity, the individual finger blocks are similarly abutted and joined together.

The method for manufacturing the wooden tiles described above will be explained in detail with reference to the specific case of manufacturing tiles from teak.

One teak log is first boiled or steamed, then cooled to room temperature, after which the temperature is quickly raised again for a second boiling or steaming. Once the teak logs begin to cool down after the second boil, they are mounted on a rotary lathe such as that manufactured by Capital Corporation of the United States. Then, when the log is cool enough but still hot enough to cut wood efficiently, it is rotated and 2.5 ff1l1
A sheet of wood slightly thicker than 1 is cut with a knife from the surface of the log. The cutting blade is 4 feet long and is oriented at an angle to maximize stress and strain relief in the log as the sheet is cut.

In this example, a sheet stripped from a log is sawed into a plurality of elongated rectangular fingers.

A knife may be used instead of a saw. The fingers are then stacked so that each corresponding edge surface is in a common plane so that an adhesive, such as a urea adhesive, can be applied to the edge surfaces.

Next, the finger is attached to a jig (
(not shown), with the surface of the jig supporting the outer circumferential surface 3 of the tile of FIG.

Additionally, the jig is removed and the tile is placed between the platens of the hot press along with similarly formed tiles of that piece. The hot press is applied to apply approximately 10 metric tons/ft2 of pressure to the tile for 3 minutes, and when the pressure is released the adhesive is cured and the tile fingers are joined together.

Once the adhesive has cured, the edges of the tile can be trimmed to form a square tile with 305 square lengths on each side. The main parts of the tile, top and bottom, are finished in a conventional manner to provide a marketable surface. After this finishing step, the tile will be approximately 2.
It has a thickness of 5 mm and has no backing base plate.

In another embodiment of manufacturing a wooden tile according to the invention, the individual fingers can be formed in the same manner as described with reference to the embodiment of FIGS. 1 and 2. However, in this alternative embodiment, the fingers 1, of which only five combinations are shown in FIG.
The finger is placed in the desired pattern on a jig (not shown) with the lower surface facing upward, and then adhesive is applied to the lower major surface 4 of the finger. A cotton mesh 5, only partially shown, is placed on the lower surface 4, the adhesive is cured by infrared light, and the tile is removed from the jig. The main surface to which no adhesive or mesh is attached becomes the front side of the tile. In the finished tile, the mesh 5 covers substantially the entire lower major surface 4 of the tile. In this embodiment, the fingers 1 are mutually supported only by cotton meshes, without applying adhesive to the sides of the fingers.

Alternatively, the cotton mesh is impregnated with adhesive and attached directly to the lower major surface of the tile. The cotton mesh is 0.3 # thick.

Although a cotton mesh has been described in connection with this embodiment, meshes made of any other material may be used.

In particular, a plastic mesh approximately 0.2 mm thick may be placed against the lower major surface of the tile and then heat welded to the tile.

The effect obtained by the tile manufacturing method according to the present invention is that by cutting the wooden sheet from a log with a knife, a rough wood grain surface can be realized on one side of the wooden sheet and a dense wood grain surface on the other side. . however,
In finished tiles, the occurrence of rough grain is not a problem, and such tiles have a flexibility not previously known in wood floor tiles. Furthermore,
The method can provide wood tiles that are thinner than those conventionally produced, and the reduced thickness also provides tiles that are lighter in weight and less expensive to manufacture.

The invention has been described above with reference to two specific embodiments. However, numerous modifications can be made to the method without departing from the scope of the invention.

For example, although sheets of wood have been described as being cut from teak logs mounted on a rotary lathe, such sheets may be cut from a round bar of wood by so-called horizontal, vertical, oblique or longitudinal cutting slicers, which are well known in the art. Also good. In any case, it should be understood that in these cases the sheets are essentially cut apart by cutting with a knife. A typical such slicer is manufactured by the Italian company "Cremona Anzero".

Additionally, although the knife is described as being approximately 4 feet long, it may be shorter or longer, for example, up to approximately 16 feet in length.

In so-called longitudinal cutting slicers, the blades may be only 10 inches long.

Other woods may be used to make such tiles, but not all of them need be subjected to boiling or steaming treatments as described above. However, basically logs are separated from round rods of wood, and sheets of wood are separated with a knife.

In one embodiment of the tile made by the method of the present invention and shown in FIG. 4, each finger is joined to each other by an adhesive provided on the abutting sides, thereby producing a completed tile. An adhesive 6 is applied to the main surface 4 of the F section, and this adhesive 6 is covered with a non-adhesive material 7 that can be peeled off.

In another embodiment of the present invention, on the F main surface of the tiles joined as shown in the embodiment of FIGS. 1 and 2,
A mesh of the type described above is joined.

The adhesive layer can be applied to any tile shape covered by the present invention. The adhesive layer may be a double-sided adhesive tape with a non-adhesive release material on its outside.

The shape of the tiles is not limited to square tiles, but may be any shape, such as elongated rectangles or hexagons.

Furthermore, the pattern of tiles formed by the 31M nodal arrangement of fingers can be varied as desired, and the fingers can be of different lengths to accommodate different patterns.

Although the wood tile embodiment has been described with reference to teak wood, any tile material selected from wood materials such as oak, exotic tile, etc. can be used.
