Description

  The present invention relates to a braiding sheet produced by slicing a braid into thin slices and a method for producing the same.

Traditionally, kumiko, which has long been used in the fields of Japanese style houses, shoji, shrines and Buddhist temples, etc., has a kumiko pattern formed by combining a large number of plate-like kumiko pieces. Is so beautiful that it has a high value as a decorative product (for example, Patent Document 1).
On the other hand, there is a parquet work as an ornament with a beautiful grain (for example, Patent Document 2).
Yosegi is different from Kumiko in that long single plates are bonded together without gaps to form a gathered block, which is cut in a direction perpendicular to the mouth, and the grain pattern that appears on the cut surface. Since it is beautiful, it is used to produce building materials such as decorative plywood, and to decorate furniture and crafts.
In addition, Hakone Yosegi is known as a representative example of Yosegi.
Hakone Yosegi is a crafted product that is made from a single block of assembled blocks that are thinly sliced to create a parquet sheet, which is then pasted on the surface of a wooden box, etc. It is highly appreciated as.
JP 2003-11596 A JP-A-7-32307

Like a parquet, a beautiful kumiko with a geometric pattern and grain has a high decorative value, but unlike a parquet, it cannot be sliced thinly. is there.
The reason why the kumiko cannot be sliced thinly lies in its structure.
In other words, the braid is formed with a mating groove at the intersection of the plate-shaped braid pieces, and the mating pieces are combined in a lattice shape by fitting the fitting grooves together, or the end of the braid piece Are combined with each other to form a geometric pattern, and a gap serving as a watermark is formed between each piece.
For this reason, when the assembled piece formed in a plate shape is sliced thinly with a cutting means such as a plane, the cutting reaction force is concentrated on the combined part of the fitting groove and the gathered part where the ends of the assembled piece are gathered. As a result, the kumiko pieces fall apart before being sliced, and damage such as peeling or turning occurs, so that it is difficult to slice thinly like a parquet.

For this reason, the inventors have tried a method of filling the gap between the braid pieces constituting the braid with a woodworking bond and slicing the braid thinly with a cutting means after the woodworking bond is cured. Since it takes 6 to 10 days for the bond to harden, the productivity is not good, and bubbles are generated in the hardened woodwork bond, resulting in a problem that the value as a decorative product is extremely lowered.
In addition, the same method was attempted using fillers such as silicon coke and hot bond, but when slicing thinly, the filling layer could not be sliced well, and a kumite sheet with sufficiently high value as a decorative product could not be obtained. There was a problem such as.
The present invention has been made in view of such circumstances, and provides a kumiko sheet manufactured by slicing a kumiko thinly and a method for manufacturing the same, so that a kumiko sheet having a high decorative effect can be obtained at a low cost. It is intended.

The method for manufacturing a braided sheet according to the present invention includes a step of fabricating a braided body in which an arbitrary braided pattern is formed by combining a large number of braided pieces, and a reinforcing layer forming material is applied to the upper surface of the braided body. The step of forming the reinforcing layer, the step of drying the reinforcing layer, and the step of thinly slicing the upper surface of the main assembly body together with the reinforcing layer to form the assembly sheet.

By the above method, the cutting reaction force when the braid body is sliced thinly is dispersed in the reinforcing layer formed so as to cover the braiding piece, and the reinforcing layer carries most of the cutting reaction force. By the reaction force, each braid piece can be dispersed thinly and sliced thinly without causing damage such as peeling or turning.
In addition, by using a transparent reinforcing layer forming material for the reinforcing layer, the grain that is the original beauty of the Kumiko appears on the front and back of the Kumiko sheet, so that a highly effective Kumiko sheet can be mass-produced at a low cost, Since the obtained braiding sheet is elastically deformable, it has high versatility as a decorative material.

  The method for manufacturing a braided sheet according to the present invention includes a step of fabricating a braided body in which an arbitrary braided pattern is formed by combining a large number of braided pieces, and a reinforcing layer forming material is applied to the upper surface of the braided body. Forming a reinforcing layer, drying the reinforcing layer, thinly slicing the upper surface of the main assembly body together with the reinforcing layer to form an assembly sheet, and superimposing the assembly sheets on each other to form an adhesive. And the process of bonding together.

By the above method, the cutting reaction force when the braid body is sliced thinly is dispersed in the reinforcing layer formed so as to cover the braiding piece, and the reinforcing layer carries most of the cutting reaction force. By the reaction force, each braid piece can be dispersed thinly and sliced thinly without causing damage such as peeling or turning.
Also, by bonding the sliced assembly sheet together, the joint portion between the assembly piece and the assembly piece is strengthened, and the joint portion between the assembly piece and the assembly piece is prevented from separating, so the strength is high. Since a kumiko sheet can be obtained and sufficient strength can be obtained only by the kumiko sheet, it can be used for decoration or the like without reinforcing the kumiko sheet with a transparent plate or the like. Thus, versatility is further improved.

  The method for producing a braided sheet according to the present invention includes a step of thinly slicing the upper side of the braided body together with the reinforcing layer to form the braided sheet and then extending the thinly sliced braided sheet into a flat shape. It is added.

  By the above method, even if the kumiko sheet is waved when the kumiko body is thinly sliced, it can be expanded in a flat shape by the stretching process, so the grain that is the original beauty of the kumiko is kumiko A kumiko sheet having a high decorative effect appearing on the front and back surfaces of the sheet can be obtained.

  In the method for producing a braided sheet of the present invention, when the reinforcing layer forming material is applied to the upper surface of the braided body, a part of the reinforcing layer forming material is applied to the crossing part of the braided piece or the side surface of the collecting part. It is a thing.

  By the above method, the cutting reaction force when slicing the braid body thinly is dispersed in the reinforcing layer formed so as to cover the braid piece, and at the same time, on the side of the intersection part and the gathering part of the braid piece. The formed reinforcing layer further enhances the strength of the intersections and gathering parts, so that it is possible to reliably prevent breakage such as peeling and turning of each assembly piece due to cutting reaction force. it can.

  The method for producing a braided sheet according to the present invention uses, as a reinforcing layer forming material, a wood bond or paint that becomes transparent or translucent when dried.

  By the said method, since the reinforcement layer forming material applied to the crossing part of the assembly piece or the side surface of the assembly part does not impair the appearance of the assembly sheet, the quality of the assembly sheet is improved.

  The method for manufacturing a kumiko sheet according to the present invention is a method of manufacturing a kumiko sheet having a multilayer structure by reversing the front and back of a plurality of kumiko sheets sliced thinly, overlapping each other, and bonding them with an adhesive. is there.

  By the above method, the long side of one assembly piece is bonded to the joint portion of the assembly piece and the assembly piece, and the joint portion of the assembly piece is separated from the long side of the assembly piece. Since the portion prevents, a higher strength braided sheet can be obtained.

  The method for producing a braided sheet according to the present invention is to produce a braided body that is approximately twice as large as the braided sheet to be manufactured, slice the braided sheet from the braided body, and then remove the braided sheet from the middle part. A braided sheet having a two-layer structure is manufactured by folding the sheets in two and bonding them together.

  According to the above method, alignment is easy when the folded folding sheet is overlapped, so that productivity is improved and positioning accuracy is improved, so that a better quality folding sheet can be obtained. .

  The assembly sheet according to the present invention is a assembly sheet formed by the assembly sheet manufacturing method according to claim 1 or 2.

  With the above structure, the grain that is the original beauty of the kumiko appears on the front and back surfaces of the kumiko sheet, so that a kumiko sheet with a high decorative effect can be obtained at a low cost, and the obtained kumiko sheet is elastically deformable. The cover of the book can be used for shoji used in houses, for displays in stores, sandwiched between glass plates, used for furniture such as table tops and partitions, or combined with cardboard It can also be used for paper products such as paper, colored paper, paper boxes and paper tubes.

According to the method for producing a braided sheet of the present invention, the cutting reaction force when the braided body is sliced thinly is dispersed in the reinforcing layer formed so as to cover the braided piece, and most of the cutting reaction force is obtained. Since the reinforcing layer carries the braided layer, each braid piece can be sliced thinly without being dispersed apart by the cutting reaction force.
Also, by bonding the sliced assembly sheet together, the joint portion between the assembly piece and the assembly piece is strengthened, and the joint portion between the assembly piece and the assembly piece is prevented from separating, so the strength is high. Since a kumiko sheet can be obtained and sufficient strength can be obtained only by the kumiko sheet, it can be used for decoration or the like without reinforcing the kumiko sheet with a transparent plate or the like. Thus, versatility is further improved.

A first embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view of the assembly main body, FIG. 2 is an explanatory view showing a process of forming the reinforcing layer, FIG. 3 is an enlarged cross-sectional view in a state where the reinforcing layer is formed on the upper surface of the assembly, and FIG. FIG. 5 is an enlarged plan view of the manufactured assembly sheet, FIG. 6 is a cross-sectional view taken along the line AA of FIG. 5, and FIG. 7 is a reinforcement of the assembly sheet with a transparent film. FIG. 8 is an explanatory view showing an example in which a kumiko sheet is used as an ornament.
A braided body 1 shown in FIG. 1 includes a frame 2 and a plate made of a plate formed by sawing, for example, wood, such as straw, cedar, and hiba, into a plate shape, and cutting it into an appropriate size. A shaped body 3 is formed.
The plate-like body 3 incorporated in the frame body 2 includes a saddle-like assembly piece 3a assembled in an oblique manner and an assembly piece provided in a gap 3c formed between the assembly pieces 3a. 3b.
A fitting groove (not shown) is formed at the intersecting portion of the assembly piece 3a combined in an oblique direction, and each assembly piece 3a is engaged with each other by fitting the engagement groove of each assembly piece 3a to each other. The child pieces 3a are combined in a lattice pattern.
The assembly piece 3b provided in the gap 3c between the assembly pieces 3a is formed by fitting the assembly piece 3b linearly or in a Y shape on the diagonal of the rhombus that forms the gap 3c. The fitting portion of the fitting groove and the assembly portion of the assembly piece 3b are bonded with an adhesive so that the child pieces 3a and 3b are not separated.
If the assembly pieces 3a and 3b can be assembled without providing the frame body 2, the frame body 2 may be omitted.

Next, a method for manufacturing the assembly sheet 4 from the assembly body 1 will be described.
In manufacturing the assembly sheet 4 from the assembly body 1, the reinforcing layer 5 is formed on the assembly body 1.
As a material for forming the reinforcing layer 5, a material having a viscosity such as a bond for woodwork, an oily or water-based paint, or a urushi and having an appropriate strength when cured is used.
In addition to the beauty of the geometric pattern as well as the beauty of the grain, the kumiko is suitable for woodworking bonds that become transparent when dried.
As the paint, transparent or translucent varnish or Japanese varnish is suitable. However, when it is desired to obtain a kumiko pattern to which paint is applied, a colored paint or urushi is also suitable.

In forming the hardened layer 5 on the assembly body 1, the hardened layer forming material is uniformly contained in the roller brush 6 used when applying the paint. Then, the roller brush 6 is rolled on the upper surface of the assembly body 1 as shown in FIG. 2, and the cured layer forming material is uniformly applied to the upper surface of the assembly body 1, and about 10 μm is applied to the upper surface of the assembly body 1. A cured layer 5 having a thickness is formed.
Thereafter, the hardened layer 5 is naturally dried or forcedly dried by using a drying means such as a heater to form the reinforcing layer 5 having sufficient strength on the upper surface of the braid body 1. When the reinforcing layer forming material is applied to the upper surface of the main body 1, a part of the reinforcing layer forming material protrudes into the gap 3c and is 1.5 mm on the side where the assembly pieces 3a and 3b intersect with each other or the gathering portion. When it is applied to a certain extent and is cured, the reinforcing layer 5a is formed at the intersections and gathering portions of the assembly pieces 3a and 3b as shown in FIG.
In addition, when sufficient intensity | strength is acquired even if it forms the reinforcement layer 5 on the upper surface of the assembly main body 1, you may abbreviate | omit the reinforcement layer 5a formed in the cross | intersection part and assembly | assembly part of the assembly piece 3a, 3b.

If the hardened layer 6 is formed on the upper surface of the assembly body 1 as follows, the process proceeds to the cutting process.
In the cutting step, the braided sheet 4 is formed by slicing the upper surface of the braided body 1 with a thickness of about 10 μm to 50 μm together with the hardened layer 5 formed on the upper surface of the braided body 1. As the cutting means 7, a manual plane having a blade width larger than the width of the braiding body 1, a superfinished plane or the like is used as the cutting means 7 so that the thickness of the entire child sheet 4 is substantially uniform.
When using a manual plane for the cutting process, as shown in FIG. 4, the cutting means 7 is moved in the horizontal direction at a substantially constant speed along the upper surface of the fixed assembly main body 1. Is sliced together with the reinforcing layer 5.

When using a cutting means 7 such as a super-finished cannula, the assembly body 1 is moved at a constant speed on the surface plate on which the blades are fixed, with the reinforcing layer 5 facing downward. The upper surface of the child body 1 is sliced thinly.
In any cutting method, the cutting reaction force at the time of cutting propagates through the assembly pieces 3a and 3b forming the assembly body 1 and concentrates at the intersections and gathering portions of the assembly pieces 3a and 3b. The cutting reaction force is dispersed in the reinforcing layer 5 formed so as to cover the pieces 3a, 3b, and most of the cutting reaction force is carried by the reinforcing layer 5, and at the same time, the intersecting portion or the collecting portion of the assembly pieces 3a, 3b. Since the reinforcing layer 5a formed on the side surface of the material improves the strength of the crossing portion and the gathering portion, the braiding pieces 3a and 3b can be thinly sliced without being dispersed apart by the cutting reaction force. become.

Since the braided sheet 4 obtained as described above is wave-shaped, the following stretching process is performed to make it flat.
Depending on the kumiko pattern formed by the kumiko pieces 3a and 3b, the direction of the grain, the thickness to be sliced, etc., the kumiko sheet 4 that has been thinly sliced may not be waved. The stretching process may be omitted.
In the stretching process, a stretching means (not shown) such as an iron, scissors, or heat roll heated at a temperature selected in consideration of the thermal effect of the reinforcing layer 5, for example, in the range of 80 ° C. to 200 ° C. is used. Then, the upper surface of the assembly sheet 4 placed on a flat surface is pressurized while being heated substantially uniformly, and the wave assembly sheet 4 is expanded into a flat shape. As shown in FIG. 6, the frame 2 and the assembly pieces 3a and 3b have a two-layer structure in which the upper surfaces are covered with a reinforcing layer.
The assembly sheet 4 is manufactured by repeating the reinforcement layer forming process, the reinforcement layer drying process, and the cutting process to a thickness at which the assembly body 1 cannot be cut, so that the assembly sheet 4 can be easily and inexpensively mass-produced. become.
Further, by using a transparent reinforcing layer forming material for the reinforcing layer, the grain that is the original beauty of the kumiko appears on the front and back surfaces of the kumiko sheet, so that the kumiko sheet 4 having a high decorative effect can be obtained.

On the other hand, the braided sheet manufactured through the above steps is weak in strength as it is, and therefore, reinforcement measures are taken according to the purpose of use.
For example, when the shade 11 of the lighting fixture 10 is manufactured as shown in FIG. 8, the two transparent plates 12 such as an acrylic resin plate cut to almost the same size as the assembly sheet 4 are shown in FIG. 7. As shown, the assembly sheet 4 is sandwiched and the transparent plates 12 are integrated by means of an adhesive.
As a result, the braiding sheet 4 is reinforced by the transparent plate 12, so that it can be deformed into an arbitrary shape, thereby making it possible to easily manufacture the cylindrical shade 11 as shown in FIG. .
Since the obtained shade 11 makes the braid pieces 3a and 3b stand out when the light of the lighting fixture 10 passes through the braid sheet 4, the Japanese shade 11 having a high decorative effect can be obtained.

Moreover, the braided sheet 4 reinforced by the transparent plate 12 is not limited to the shade 11 of the lighting fixture 10 and can be used for any application.
For example, it can be used for shoji screens used in houses, for displays in stores, etc., sandwiched between glass plates, and used for furniture such as table tops and partitions, etc. It can also be used for paper products such as covers, colored paper, paper boxes, and paper tubes.
Further, a small assembly body 1 having no frame 2 is formed by assembly pieces 3a and 3b, and this assembly body 1 is sliced in the same manner as described above to produce the assembly sheet 4, thereby providing a cup or the like. It can also be used as a coaster on which the container is placed, and can also be used as an ornament by combining a plurality of kumiko sheets 4.

In the first embodiment described above, the reinforcing sheet 4 obtained in the cutting process and the extending process is sandwiched with the transparent plate 12 so that the reinforcing element 3a, 3b is not disassembled from the joint portion. However, a second embodiment in which the braided sheet 4 is reinforced without using the transparent plate 12 will be described below.
Since each process until slicing the assembly body 1 is the same as that of the first embodiment, the description thereof is omitted.

In the case of the assembly sheet 4 shown in FIG. 9 formed by slicing the assembly body 1, concave grooves 3j and 3k are formed in the long assembly pieces 3d and 3e as shown in FIG. The braided pattern is formed by fitting the concave grooves 3j and 3k to each other.
For this reason, when the surface of the braid body 1 is sliced thinly, as shown in FIG. 11, between the long side portions 3g of one braid piece 3d, both ends of the short side portion 3h of the other braid piece 3e have a seam 3f. Since the abutting portions are bonded with an adhesive, the assembly pieces 3d and 3e may be separated from the joint 3f portion when a strong force is applied.
Therefore, in the second embodiment, a measure for strengthening the braided sheet 4 is implemented by superposing and bonding a plurality of braided sheets 4 whose front and back are reversed.
That is, each of the assembly pieces 3d and 3e of the assembly sheet 4 formed by thinly slicing the assembly body 1 is, for example, the long side portion of one assembly piece 3d inclined downward to the right as shown in FIG. The short side portion 3h of the assembly piece 3e inclined downward to the left is provided between 3g, and a joint 3f is formed between the side surface of the long side portion 3g and the end portion of the short side portion 3h. .

On the other hand, when the front and back of the assembly sheet 4 shown in FIG. 9 is reversed, the long side portion 3g of the assembly piece 3d that has been lowered to the right, for example, is inclined downward to the left as shown in FIG. When a part is enlarged, the position of the joint 3f is also reversed as shown in FIG.
Therefore, when the two assembly sheets 4 with the front and back reversed are accurately overlapped with each other, as shown in FIG. 14, the joint 3f portion between the long side portion 3g of the assembly piece 3d and the short side portion 3h of the assembly piece 3e is formed. The long side portion 3g of the braid piece 3d passes through.
14 is formed by laminating both of them together with an adhesive such as a woodworking bond in a state where the assembly sheet 4 shown in FIG. 12 is turned upside down on the lower side of the assembly sheet 4 shown in FIG. A laminar structure sheet 4 is shown.
As is apparent from FIG. 14, the long side 3g of the assembly piece 3d is bonded from the lower side to the joint 3f portion of the assembly piece 3d and assembly piece 3e of the assembly sheet 4 shown in FIG. The long side portion 3g of the braid piece 3d and the long side portion 3g of the braid piece 3d prevent the separation of the seam 3f portion of the short side portion 3h of the braid piece 3e. 4 is obtained. FIG. 15 is an enlarged sectional view taken along the line DD in FIG.

As described above, by reinforcing and bonding the two sheeting sheets 4 with the front and back reversed to each other, a reinforcing measure such as sandwiching the sheeting sheet 4 with the transparent plate 12 as in the first embodiment. Even if it does not do, since sufficient intensity | strength can be acquired only with the assembly sheet | seat 4, it becomes employable for a wider range of uses, and versatility improves further.
In the second embodiment, the upper and lower surfaces of the assembly sheet 4 obtained by thinly slicing the upper surface of the assembly body 1 are reversed and overlapped with each other and bonded with an adhesive. Since the lower surface is in a state in which the direction of the assembly piece 3d and the assembly piece 3e is reversed, the assembly sheet 4 formed by slicing the upper surface of the assembly body 1 and the lower surface of the assembly body 1 are sliced. If the formed assembly sheet 4 is bonded together, the assembly sheet 4 having the same two-layer structure as in the second embodiment can be obtained without reversing the front and back of one assembly sheet 4. .
In the second embodiment, the case where the front and back surfaces of the two sheeting sheets 4 are reversed and bonded together has been described. However, if three or more sheeting sheets 4 are bonded together, the strength of the joint 3f is further increased. Therefore, even if a strong force is applied when the braid sheet 4 is processed or used for decoration or the like, a stronger braid sheet 4 that is not easily damaged can be obtained.

In the above description, the case where a single assembly sheet 4 is manufactured by reversing and attaching the front and back of a plurality of assembly sheets 4 sliced from the assembly body 1 has been described. As shown, in the case of right and left (or vertically symmetrical) with respect to the center line OO of the intermediate portion, it may be manufactured as in the following third embodiment.
FIG. 16 shows a third embodiment, in which the assembly body 1 is manufactured approximately twice as much as the assembly sheet 4 to be manufactured, and the assembly sheet 4 is sliced from the assembly body 1 and is approximately in the middle. FIG. 17 shows a state in which the two-layer structure assembly sheet 4 shown in FIG. 18 is manufactured by folding it in two from the center line OO of the section as shown in FIG. Since the front and back are reversed by folding the braided sheet 4 sliced in advance twice in length almost from the middle part, the same strength as in the second embodiment can be obtained by bonding them together. A kumiko sheet 4 having a high height can be obtained.
In addition, according to the third embodiment, since alignment when the folded folding sheet 4 is stacked is easy, productivity is improved and alignment accuracy is improved, so that the quality is better. A kumiko sheet 4 is obtained.

In the first and second embodiments, the reinforcing layers 5 and 5a are formed on the upper surface and the side surface of the assembly body 1 using the roller brush 6, but the reinforcement layer forming material is used as the upper surface of the assembly body 1. Alternatively, the reinforcing layer 5 may be formed by spraying (spraying) the side surfaces of the assembly pieces 3a, 3b, 3d, 3e. In this case, the reinforcement layer 5a is formed on the side surfaces of the assembly pieces 3a, 3b, 3d, 3e. Therefore, even if the coating film is thin, sufficient strength can be obtained, and the braid body 1 is immersed in the reinforcing layer forming material accommodated in the container to form the reinforcing layer 5. May be.
The reinforcing layer 5 is transparent or translucent, but even if it is colored, the beautiful geometric pattern of the kumiko is not impaired. Especially by applying urushi etc., high value is obtained as a craft or art. Be able to.
Furthermore, woodworking bond or paint is used as the reinforcing layer forming material, but a resin film may be bonded in advance to the upper surface of the assembly body 1 to form the reinforcement layer 5. In this case, the upper surface of the assembly body 1 together with the resin film. When the braided sheet 4 is manufactured by slicing it into thin pieces, the obtained braided sheet 4 will not be waved, so that the stretching process is not necessary.
