After making the surface substantially parallel to the back surface and forming a longitudinal groove C on the front surface, split the bamboo piece along the groove C to form divided pieces d... Thereafter, as shown in FIG. 13, the divided pieces d... are arranged in parallel, and each divided piece d... is connected with the weaving thread e... to form the sheet body f.
After forming the sheet body f, a lining fabric g was attached to the back surface of the sheet body f.

[Problems to be solved by the invention] In the method described in the conventional technique, the body part is discarded, which is not desirable in terms of resources, and the divided pieces d must be connected with weaving thread, which is inefficient. This had the disadvantage of requiring a loom, resulting in high costs. Furthermore, since the weaving threads of the product are exposed on the front side, they have the disadvantage that they are uncomfortable to the touch, the weaving threads are easily soiled, and it is difficult to clean the vicinity of the weaving threads.Furthermore, the weaving threads are worn out and cut. There was a risk of this happening, and there was a problem with durability.

Therefore, the present invention provides a bamboo rug that feels good when used, is stain resistant, is easy to clean, can minimize the number of discarded bamboo parts, and is highly durable, as well as a method for manufacturing the same. The purpose is to provide

[Means to solve the problem]

In order to achieve the above-mentioned object, the bamboo rug according to the present invention has the following features:
A large number of grooves parallel to the bonded surface of each bamboo piece are formed on the front side of a sheet body in which a large number of bamboo pieces are glued in parallel and the front side and the back side are cut surfaces in the radial direction of the bamboo. , and a backing fabric is pasted on the back side of the sheet body, and the method for manufacturing the bamboo rug includes cutting the bamboo along the longitudinal direction to form cut pieces of a predetermined length, and then A sheet body forming piece is formed by aligning the width and thickness of the cut piece to a predetermined constant size, and then,
After applying adhesive to the front and/or back surfaces of the sheet body forming pieces, each sheet body forming piece is laminated and compressed in the thickness direction to form a rectangular parallelepiped-shaped block body, and then the block body is cut at a predetermined pitch in the thickness direction of the seal integrally formed piece to form a sheet body whose front and back surfaces are the radially cut ends of the bamboo. After forming a large number of grooves parallel to the adhesive surface on the surface, a backing fabric is attached to the back surface of the sheet body.

[Effect]

Since no weaving yarn is used in the sheet body, and the front surface of the sheet body is a radially cut surface of bamboo, the so-called straight grain is visible.

Furthermore, according to the manufacturing method of the present invention, there is no need to arrange divided pieces with very small width dimensions side by side and weave them with weaving thread, and when forming a sheet body forming piece, the inner body part of the bamboo is removed. Even if it is left, the sheet body has a strong skin part, and the sheet body as a whole is strong.
There is no need to throw away the bamboo flesh. In addition, when forming grooves,
There is no need to match the pitch of the grooves to the pitch of the adhesive surface.

〔Example〕

Hereinafter, the present invention will be explained in detail based on drawings showing examples.

FIGS. 1 and 2 show a bamboo rug according to the present invention, which comprises a bamboo sheet body 3 having a large number of parallel grooves 2 formed on its front surface 1, and It consists of a lining fabric 5 attached to the back surface 4 of the body 3.

This sheet body 3 is made up of a large number of bamboo pieces 6 adhered in parallel, and the adhesive surfaces 7 are parallel to the grooves 2, but the pitches thereof are not the same.

Further, the surface 1 on the front side of the sheet body 3 is a radial cut surface of bamboo, which is a so-called straight-grained surface.

Next, the method for manufacturing this bamboo rug will be explained.

First, as shown in FIG. 3, the bamboo 8 is longitudinally cut along radial cutting lines 9 formed at predetermined pitches in the circumferential direction, and cut pieces 1o of a predetermined length are...・Form. Next, as shown in FIG. 4, the width dimension A and the thickness dimension B of the cut piece 1o are made equal to a predetermined constant dimension.

That is, as shown in Fig. 4 (1), both ends are cut off as shown by the imaginary lines, and the front and back sides are cut off as shown in Fig. 4 (If).
The sheet body forming piece 11 having a rectangular cross section is formed as shown in FIG. 4 (III).

Then, adhesive is applied to the front surface 12 and/or back surface 13 of the sheet body forming piece 11, and as shown in FIG. Sheet body forming pieces 11... are pressed into the upper mold 14a and lower mold 14 of the press machine 14.
b and compressed in the thickness direction to form a rectangular parallelepiped-shaped block 15 as shown in FIG. In this case, the adhesive is applied to the surface 1 of the uppermost sheet body forming piece 11.
2 and the back surface 13 of the lowest sheet body forming piece 11 are not coated. Moreover, in the case of the intermediate sheet body forming pieces 11..., it is free to apply the coating to either the front surface 12 or the back surface 13, or to both surfaces.

Then, the block body 15 is cut at a predetermined pitch along the thickness direction of the sheet body forming piece 11, as shown by the imaginary line, to form a sheet body 3 having a predetermined thickness dimension t. Therefore,
This sheet body 3 is formed by adhering a large number of bamboo pieces 6 in parallel, and also has a front surface 1 and a back surface 4.
is a radial cut surface of bamboo. In this case, if the cutting is performed using a cutting machine having a plurality of saw teeth at a pitch corresponding to the thickness dimension t, there is an advantage that a plurality of sheet bodies 3 can be formed at one time.

Next, a large number of grooves 2 parallel to the adhesive surface 7 are formed on the front surface 1 of the sheet body 3. Specifically, groove 2
. . . is a cutter 18 in which circumferential blade portions 17 . Let it form. In this case, it is not necessary to match the pitch of the blade portion 17 and the pitch of the adhesive surface 7 as in the embodiment. However, since the sheet body 16 is integrated, the adhesive surface 7 will not come off. Therefore, the formation of the groove 2 is not affected by the position of the bonding surface 7 and is easy to form. Further, the cutter 18 is formed with a blade portion 23 for cutting the outer surface 1 along the longitudinal direction, and surface processing is performed.

Then, a second
As shown in the figure, the lining base fabric 5 is attached.

In this case, after arranging a plurality of sheet bodies 3 (width dimension W) in parallel on the lining fabric 5 (two sheets in the illustration), they are compressed with a press machine and the backing The upholstery fabric 5 is attached. In this case, an adhesive is interposed between the lining fabric 5 and the sheet body 3, but the adhesive is applied to either the upper surface of the lining fabric 5 or the lower surface (back surface 4) of the sheet body. You are free to apply it on either side or on both sides.

Therefore, the thickness dimension t of the sheet body 3 is usually 1.5 ~
The remaining portion 1 of the sheet body 3 corresponding to the groove 2 is preferably 4 m.
The dimension C of 9 is preferably 0.1 mm to 0.8 mm.

Therefore, the sheet body 3 of this bamboo rug is initially a one-piece piece, but if it is made into a rolled-up shape at the time of shipping, etc., the remaining 1
9 is cut, resulting in a large number of divided pieces arranged in parallel like a conventional bamboo rug.

Further, as the sheet body forming piece 11, as shown in FIG. 8(1), after cutting both ends of the cut piece 10, as shown in FIG.
) As shown in FIG. 8, the cut piece 10 is cut and removed in an arc shape to obtain a sheet body forming piece 11 with the front surface 12 and the back surface 13 having an arc shape, as shown in FIG. 8 (II+). Preferably,
In this case, the press machine 20 has an upper mold 20 as shown in FIG.
A recess 21 corresponding to the front surface 12 of the sheet body forming piece 11 is formed in the lower mold 20b, and the sheet body forming piece 11 is formed in the lower mold 20b.
A convex portion 22 corresponding to the back surface 13 is formed.

In this case as well, as shown in FIG. 10, the block body 15 is cut at a predetermined pitch along the thickness direction of the sheet body forming piece 11, as shown by the imaginary line, so that the block body 15 has a predetermined thickness. A sheet body 3 having a dimension t is formed. Therefore, thereafter, a bamboo rug is manufactured by the method described above. In this case, both ends are cut by the cutting blades 24, 24 on both ends of the cutter 18, as shown in FIG. 7, and the width W of the sheet body 3 is determined.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and the design may be changed without departing from the gist of the present invention. For example, in the embodiments, the cut pieces are made by dividing the bamboo 8 into six in cross section. However, it is of course free to make the length larger or smaller than this, and the length dimension of the sheet body forming piece 11,
Thickness dimension B and width dimension A can be set freely, and furthermore,
The number of sheet body forming pieces 11 constituting the block body 15 can be freely increased or decreased, and the thickness dimension of the sheet body 3 and the groove 2 can be adjusted freely.
You can also set the pitch freely. It is also preferable to coat the front surface l of the sheet body 3 with a resin such as urethane.

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the effects described below.

Since this bamboo rug does not use weaving threads, it looks good and has excellent durability, has a good feel when used, and is also stain resistant and easy to clean. Furthermore, since there is almost no need to discard the inner flesh of the bamboo 8, there is less wastage of materials and resources are saved. Further, since the sheet body 3 is formed by slicing the block body 15, its thickness t can be freely set, and bamboo mats with various thicknesses t can be easily formed. In addition, since the front surface 1 and the back surface 4 of the sheet body 3 are the radial cut surfaces of bamboo, the front surface 1 and the back surface 4 have a so-called straight grain, and this sheet body 3 has a so-called "straight grain".
It does not cause any warpage and has an excellent design.

Furthermore, when forming the grooves 2, it is not necessary to match the pitch of the grooves 2 to the pitch of the bonding surface 7, so the work is simple and the productivity is excellent. Also,
