Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a shutter-type door material, particularly a flexible shutter-type door material used, for example, as a door for furniture.

Conventionally, this type of door material has been known to be made by connecting a large number of narrow strips of wood, synthetic resin, or metal in a manner that allows them to be bent, or by attaching them to a flexible sheet. . However, not only is it generally very time-consuming to manufacture, but also there are slight gaps between the strips, and even if there is a wood grain pattern, it cannot be expressed as a continuous pattern, so it does not look perfect in terms of appearance. The problem was that it was not possible to make it look like a single board.

The present invention aims to provide a simple method for manufacturing a shutter-type door material that eliminates these drawbacks.

That is, the method for manufacturing a shutter-type door material according to the present invention is to create a laminate by integrally laminating a flexible backing sheet such as cloth on the back side of a board material such as a wooden board, and place the laminate on a feed table. The laminate is placed and fed intermittently so that it protrudes by a predetermined width from the side edge of the feed table, and when this feeding is stopped, only the plate materials of the laminate are sequentially cut at positions on the side edge of the feed table. , the cutting is performed using a cutting blade whose blade surface facing the laminate feeding direction is an inclined cutting surface and the opposite surface is a vertical cutting surface, and as the cutting progresses, the laminate is moved from the feed base. This is characterized in that the protruding portion is freely bent downward in accordance with the biting of the inclined cutting surface to form a gapless cut.

This will be further explained below with reference to the illustrated embodiment.

First, as shown in Fig. 1, a strong and thin flexible backing sheet 3 is placed on the back side of a plate material 2 that forms the main body of the door material.
are stacked and glued together to form a laminated board 1 of the required size.
Create. The plate material 2 is most preferably a decorative plywood with a decorative wood veneer pasted on its surface, but a plate material whose surface has been decorated by pasting a printed sheet or painting may also be used. The material is not particularly limited to wood, as long as it can be cut with a knife. Furthermore, the flexible backing sheet 3 may be of any material as long as it does not easily break due to fatigue when bent. For example, linen cloth, cotton cloth, etc. are preferably used.

Next, as shown in FIG. 2, the above-mentioned laminate 1 is placed on the feed table 4 of the cutting machine, and is intermittently fed so as to protrude from the side edge of the feed table 4 by a predetermined width at a time. The cutting blade 5 is operated in synchronization with the above, and when the feeding is stopped, the laminated plate 1
The plates 2 are sequentially cut at positions above the side edge 4a of the feed table 4, leaving only the backing sheet 3.

The cutting blade 5 used for this cutting is particularly equipped with a sharp cutting edge, with the blade surface facing the feeding direction of the laminate 1 having an inclined cutting surface 5a, and the opposite surface having a vertical cutting surface 5b. Furthermore, as shown in FIGS. 3 and 4, as the cutting progresses, the protruding portion of the laminate 1 from the feed table 4 is cut into the plate material 2 of the inclined cutting surface 5b. It shall be bent freely downward in response to the biting. Through such cutting operations, the cuts 6 formed in the plate material 2 are formed with virtually no gaps, as shown in FIG.

Therefore, when the door material 1a manufactured by repeated cutting as described above is stretched flat as shown in FIG. Even though it is never touched, it appears to be made of a single, continuous plate. Of course, such external characteristics can be made even more perfect by applying a paint finish or the like to the surface of the door material 1a after being stretched into a flat shape after cutting.

Note that the door material 1a manufactured as described above
As shown in FIG. 6, this is used for the door of storage furniture A, etc., with an appropriate edge material 7 attached to one end.

According to this invention, after pasting the board material on the backing sheet in advance, only the board material is cut and formed into a bendable form, so that the surface pattern, wood grain, etc. of the board material can be continuously displayed as it is as a whole. Not only is this possible, but the cuts made by cutting are seamless, so the gaps between the strips are not visible as in conventional products, and when the door is in a flat state with the door closed, the entire surface is visible when viewed from the front. It looks like a single piece of board and has an extremely good appearance. Furthermore, the manufacturing process is relatively simple, as it is produced by cutting only the laminate that has been pre-fabricated to the required size from board materials and backing sheets as described above, and has the advantage of being mass-producible and being available at low cost. There is also.

Claims (1)

[Claims] 1. A laminate is made by laminating and integrating a flexible backing sheet such as cloth on the back side of a board material such as a wooden board, and the laminate is placed on a feed table and the laminate is sequentially spread to a predetermined width from the side edge of the feed table. While intermittently feeding the laminate so that the laminate sticks out intermittently, when this feeding is stopped, only the plate material of the laminate is sequentially cut at a position on the side edge of the feed base, and the cutting is performed using a blade surface facing in the feeding direction of the laminate. Using a cutting blade having an inclined cutting surface and a vertical cutting surface on the opposite side, as the cutting progresses, the portion of the laminate that protrudes from the feed base corresponds to the biting of the inclined cutting surface. A method for manufacturing a shutter type door material, characterized in that the material is bent freely downward to form a gapless cut.
