[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a wide surface finishing material which is used by being wrapped around the surface of box furniture such as clothes dance, the surface of a door or wall of a house, or the surface of a pillar. It is a thing.

[0002]

2. Description of the Related Art Finger joint processing is applied to both ends of a veneer obtained by cutting natural wood with a rotary lace and the like, and a temporary fixing tape is attached to the surface of the finger joint processed portion to form a tape-shaped veneer. Japanese Unexamined Patent Application Publication No. Hei 3 (1999) -311:
It is disclosed in Japanese Patent No. 211004. The name wood veneer roll disclosed in this publication usually has a width of 12 to 4
0 mm is generally used, and it is mainly used for wood work furniture and fittings, or edge pasting for displays, etc. due to its narrow width.
A product with a width of 300 mm is also manufactured and sold as a custom-made product.

[0003]

The width of the custom-made wide name tree roll is only 300 mm at the maximum, and the veneers having the same width are used side by side in the vertical or horizontal direction to cover the wide surface. Since it was necessary, the work was extremely troublesome. Further, since the conventional name tree roll is formed by directly cutting a 300 mm veneer plate by a rotary race or the like, there is a problem that it is technically extremely difficult to obtain a name tree roll having a width larger than that.

In view of the above circumstances, the present invention aims to provide a manufacturing method capable of easily and easily manufacturing a surface finishing material composed of a wide veneer capable of directly covering a wide surface portion. is there.

[0005]

In order to achieve the above-mentioned object, the surface finishing material of the present invention is characterized in that a wide surface finishing material is manufactured by sequentially carrying out the following steps. Manufacturing method. (1) A plurality of veneer plates having a predetermined width, length, and thickness whose surfaces are smoothed by hot pressing and / or cold pressing are stacked to form a laminated body, and the laminated body is arranged along the length direction of the laminated body. Side parallel cutting step of cutting both sides in parallel (2) Adhesive applying step of applying thermoplastic synthetic resin adhesive to the entire side surface along the length direction of the laminated body in which both sides are cut in parallel (3) ) Separation / drying step in which the laminated body coated with the thermoplastic synthetic resin adhesive is separated and the synthetic resin adhesive coated along the side edges is dried (4) The coated thermoplastic synthetic resin adhesive is The dried veneer plates are arranged in parallel so that the side edges in the lengthwise direction contact each other, and the synthetic resin adhesive is activated while heating the side edge parts in the longitudinal direction of the adjacent veneer plates at a predetermined temperature. Lateral stripping step of joining adjacent veneer plates to each other (5) Laterally stripped veneer plates are joined in the length direction to form a tape, and a fleece is adhered to the back surface of the lateral stripped veneer formed in the tape shape to line it. After that, a finishing process in which the surface is ground to adjust the thickness to a constant value and wound into a roll.

In the present invention, the veneer plate does not heat a single plate having a thickness of 0.3 to 1.0 mm obtained by cutting natural wood such as oak or pine tree with a rotary race, etc. It is either cold-pressed by pressing and then temporarily pressed, or hot pressed by heating while hot-pressing, or temporarily and heat-pressed to smooth the entire surface. is there. The preferable thickness of the projecting plate is 0.4 to 0.6 mm.

Such a veneer has a width of, for example, 10 mm.
For example, it is preliminarily cut into 15 mm or the like, and after stacking about 20 to 60 smoothed veneers to form a laminated body, in order to make the width of each veneer constant, The side is cut by a cutting machine called a guillotine to form a laminate having a constant width.

In the laminated body in which the side edges along the length direction are cut in parallel, a thermoplastic synthetic resin adhesive is applied to the cut side edges. The synthetic resin adhesive used is not particularly limited as long as it is a thermoplastic resin, but vinyl acetate resin adhesive, particularly vinyl acetate resin emulsion wood adhesive is preferable from the viewpoint of compatibility with veneer and price. The coating on the laminate can be automatically performed by a gluing machine.

The laminated body coated with the synthetic resin adhesive is spread one by one to cure the coated adhesive. Means for curing include leaving at room temperature or forced cooling. The time required for curing depends on the synthetic resin adhesive used, but with vinyl acetate resin emulsion, 10-15% at room temperature.
It's about a minute.

The projecting plates having the synthetic resin adhesive applied to the side edges along the longitudinal direction cured are arranged in parallel so that the side edges in the longitudinal direction come into contact with each other, and the abutting contact is made. When the part is heated at a temperature of 180 to 200 ° C., the hardened synthetic resin adhesive is reactivated and the veneer plates are bonded and fixed to each other. At that time, the veneer has a mismatch method in which the front surfaces are laterally stripped and a book match method in which the front surface and the back surface are alternately laterally stripped, so one of the methods is adopted to perform lateral stripping. . Horizontal strips, for example, width 3
If you want to obtain a surface finish of 00 mm, width 100
It suffices to connect three 3 mm projection plates in the lateral direction, and it is possible to freely select the width of the surface finish material depending on the width of the projection plate to be used and the number of lateral strips.

In order to make the projecting plate which is laterally stripped and has a predetermined width to be long, the front and rear side edges which are orthogonal to the side edges in the longitudinal direction are subjected to finger joint processing, and one finger joint section is formed. The other finger joint part is meshed, a temporary fixing adhesive tape of a predetermined width is attached to the surface of the meshed part, and the tape is wound into a tape shape. Then, while unwinding the rolled long veneer, the back side is lined with a fleece made of non-woven fabric with a synthetic resin adhesive, and then the surface is ground with a sander and wound into a roll. It is used as a surface finish material.

[0012]

According to the method of manufacturing a surface finish material of the present invention, after laminating a plurality of veneer plates having a smoothed surface, a thermoplastic synthetic resin adhesive is applied to the side edges along the longitudinal direction, and the veneer plate is applied after application. Spread the sheets one by one to cure the synthetic resin adhesive, and then contact the application parts of the veneer boards coated with the synthetic resin adhesive with each other, and heat the contact parts to laterally strip the surface of a predetermined width. To obtain the finish, a wide surface finish can be easily and easily manufactured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The method for producing a surface finish material according to the present invention will be described below more specifically with reference to the accompanying drawings. [Pretreatment of veneer] Thickness of 0.5m obtained by cutting natural wood
A veneer having a width of about 12 to 13 mm and a width of 12 to 13 mm is passed through a hot press machine to make the surface smooth without waviness and to have a dense and uneven surface. At that time, the veneer having a small surface roughness may be simply cold pressed, and when the roughness is severe, the surface roughness may be eliminated by alternately passing it through a hot press machine and a cold press machine as needed.

[Side parallel cutting step] 50 veneer plates 1a, 1b, 1c, ...
The stacked body 2 is formed by stacking the sheets as shown in FIG. 1, and each side S ₁ and S ₂ along the longitudinal direction of the stacked body 2 is cut using a guillotine to form each veneer 1a, 1b, 1c.・
··· Make the width of 10 mm.

[Adhesive Coating Step] The laminated body ₂ with both sides S ₁ and S ₂ cut off is kept in that state and has a predetermined thickness along the longitudinal direction (about 0.5 mm × 50 sheets = about 25).
To the left and right side edges having a thickness of ~ 27 mm), a vinyl acetate resin emulsion G that is a thermoplastic synthetic resin adhesive.
Is applied with a gluing machine. (Fig. 2)

[Separation / Drying Process] The laminated body 2 coated with the vinyl acetate resin emulsion G is spread and coated with the veneer plates 1a, 1b, 1c, 1d, ... As shown in FIG. The obtained vinyl acetate resin emulsion G is naturally dried at room temperature to cure. When this curing is naturally dried at room temperature, it can be left for about 10 to 15 minutes and forcedly dried.

[Horizontal Stripping Step] As for the veneer plate on which the applied vinyl acetate resin emulsion G is cured, a plurality of veneer plates matching the width to be obtained are laterally stripped. For example, when a surface finish material having a width of 30 mm is used, three projecting plates 1a, 1b, 1c having a width cut to 10 mm are brought into contact with each other at their side edges along the longitudinal direction of each projecting plate as shown in FIG. So that the contact parts are at a temperature of about 180-200 ° C.
The vinyl acetate resin emulsion cured on the side edge of each veneer is reactivated by pressurizing and is integrally bonded to form a wide surface finish material 3. When forming this wide surface finish material 3,
When the adjacent veneer plates are laterally stripped only at the surface portion, the finished surface finish does not have the same grain, but the grain can be matched by alternately connecting the front and back sides.

[Finger Joint Processing Step] The wide surface finish material 3 thus obtained is subjected to finger joint processing at the front and rear edge portions that are orthogonal to the side edges in the longitudinal direction (not shown). After forming the part, the finger joint part of one wide surface finish material is meshed with the finger joint part of the other wide surface finish material, and the adhesive is applied to the back surface of the mesh part. Stick a stop tape and wind it around the take-up roll while making it long.

[Finishing process] Next, while rewinding the wide surface finishing material 3 wound on the winding roll,
As shown in, while applying the adhesive 4 made of a vinyl acetate resin emulsion to the entire back surface, 0.05 to 0.10 m
After fusing the m-thick fleece 5 and passing it between the rolls 7 and 7 for pressure bonding, the surface side of the wide surface finish material 3 is sanded to adjust the thickness evenly and the fingers of the veneer plates The temporary fixing tape 6 attached to the joint portion is ground and removed, and this is sequentially wound to form a tape-shaped wide surface finishing material. In this embodiment, the tape-like surface finish material is subjected to finger joint processing on the small side of the surface finish material to be joined in a long length, but if it can be joined in a long length, the finger joint processing treatment is not always necessary. Is not what you need.

[0020]

According to the method for producing a surface finish material of the present invention, a veneer having a rough surface is hot-pressed and / or cold-pressed to be smoothed, and then a large number of sheets are stacked to form a laminate. Both sides along the longitudinal direction of the laminate are cut with guillotine or the like to form a laminate of a veneer having a predetermined width, and thermoplastic synthetic resin adhesive is applied to the cut sides of the laminate, and then the laminate is spread. As a single veneer plate, cure the synthetic resin adhesive applied to the side edges along the longitudinal direction, and then bring the plurality of veneer plates into contact with each side edge so as to have a predetermined width. By arranging and curing the cured synthetic resin adhesive and reactivating it, a plurality of veneers are stripped sideways and integrally joined, and then this is made long and a fleece is used on its back surface. To stick Since Accordingly it is an wide tape-like facings, it is possible to produce a wide facings width very simply and easily. In addition, the surface finish obtained by this production method is extremely economical and versatile because it can be cut into a predetermined size before use.
