Description

[Detailed description of the invention] [Technical field 1 It relates to a manufacturing method.

[Background Art] Conventionally, when forming a feature board material curved in an abbreviated shape, a top sheet 2 is pasted on one side of a wooden board 1, and a fifth
As shown in Fig. 5(a), a V-shaped groove 3' is bored in the wooden board 1, and the wood board 1 is bent into an oval shape through the groove 113' as shown in Fig. 5(b). However, the end surfaces on both sides of the groove 3' were glued together. However, when manufactured in this manner, the corners of the surface were sharp, and a soft appearance with a curved surface could not be achieved.

[Object of the Invention] The present invention has been made in view of the above points, and an object of the present invention is to easily produce a curved feature plate material having a soft appearance with curved surface corners! ! An object of the present invention is to provide a method for manufacturing a manufactured board material.

[Disclosure of the Invention] The method for producing curved feature board materials of the present invention includes pasting a surface sheet 2 on one side of a wooden board 1, and attaching a wooden button 4 at the location to be curved.
-Make the sound! A space 3 is formed, and the auxiliary material 4 having a fan-shaped cross section is arranged so that the curved surface 4a side faces 211 m, and the curved surface 4a of the auxiliary material 4 is adhered to the top sheet 2. The wooden board 1 is bent into an oval shape through the space 3, and the end surfaces 1a on both sides of the space 3 are connected to the both sides 4b of the auxiliary material 4.
This is characterized by the fact that it adheres to the substrate, and the drawbacks of the conventional example are solved by configuring it as described above. In other words, by bending using the auxiliary material 4 having a sector-shaped cross section as described above, the corner surfaces can be made into curved surfaces, making it possible to easily manufacture a product with a soft appearance.

The present invention will be explained in detail below with reference to Examples.

A top sheet 2 made of a synthetic resin sheet such as a polyvinyl chloride sheet is adhered to one side of a wooden board 1 such as plywood or starwood. First, in the first processing, the shaded portion in FIG. 1 is cut to a constant width, and a space 3 containing only the top sheet 2 is formed. This space 3 is surface sea) 21
In the first and second processing, where the cross section is wide and trapezoidal,
Adhesive is applied to the back surface of the top sheet 2 exposed in the space 3, and as shown in FIG. be done. At this time, the radius of curvature r of the auxiliary material 4 is larger than the thickness t of the wooden board 1, and is approximately the same as the width l of the end surface 1a of the wooden board 1 on both sides of the space 3. In the tertiary processing, as shown in FIG. 3, the auxiliary material 4 is pressed from above and below by the upper roller 5 and a pair of lower loafs 6, and the auxiliary material 4 is pushed toward the lower roller 6 side, and a surface sheet is formed on the curved surface 4a of the auxiliary material 4. 2 are adhered, and adhesive is applied to both side surfaces 4b of the auxiliary material 4. In the fourth processing, the wooden board 1 is bent into an oval shape through the space 3, and pressed with a roller in the direction of arrow A in FIG.
The end surfaces 1 & on both sides of the space 3 are bonded. In this way, a feature board material having curved corners is formed.

Note that by changing the inclination angle of the end surfaces 1a on both sides of the space 3 of the wooden board 1 and the angle α between the side surfaces 4b on both sides of the auxiliary material 4, the bending angle can be freely changed.

[Effects of the Invention] As described above, the present invention cuts a wooden board to a certain width at a curved point to form a space for only the top sheet, and then uses an auxiliary material with a fan-shaped cross section so that the curved side faces the top sheet. The curved surface of the auxiliary material is glued to the top sheet, and then the wooden board is bent into an abbreviated shape through the space, and the end surfaces on both sides of the space are glued to both sides of the auxiliary material, so the cross section It is possible to form a curved feature board material with a soft appearance by using the fan-shaped auxiliary material so that the surface of the corner part becomes a curved surface, and the curved surface can be easily formed just by using the auxiliary material. By changing the angle between both sides of the material, the angle of the up-curving board material can be changed freely.
