Abstract

The present invention provides a method for producing a wooden sudder that can use scrap materials.
A unit plate piece is produced by cutting two parallel sides of a rectangular end plate piece of natural wood with an inclination angle to form a single-edged gradient surface on each of the two sides. Next, the unit strip pieces having different colors are successively continued by bonding the sloped surfaces to produce a standard strip plate-like intermediate material. Thereafter, the belt-like intermediate material is cut and divided into small widths w along the longitudinal direction to produce the small belt-like chin 8. Weaving yarns 12 for weaving the small band-like ridges 8 are arranged corresponding to the color change boundary portions of the ridges 8 due to the adhesion between the gradient surfaces.

Description

  The present invention relates to a method for producing wooden sudder.

  Conventionally, as a method of manufacturing wooden blind slats, there are ones in which a front band plate part and a back band plate part are formed using natural wood, and a shape-maintaining core material is bonded as a sandwich between them (for example, , See Patent Document 1). The same plate material was used for this slat over the entire length in the longitudinal direction. Similarly, in the manufacturing method of the wooden sudder, the same plate material is used over the entire length in the longitudinal direction of each plate material knitted with the woven yarn.

  However, it is necessary to use a large plate material having a predetermined size or more. In addition, there is a drawback that it is difficult to form a pattern using the natural grain.

JP 2002-242556 A

  The problem to be solved is that a large plate material having a predetermined size or more needs to be used, and so-called waste material cannot be used. In addition, it is difficult to form a pattern using the natural grain. Furthermore, it is difficult to produce a checkered pattern etc. beautifully and efficiently.

Therefore, in the method for producing the wooden sudder according to the present invention, a plurality of thin plate-shaped impregnated materials made of natural timber having a grain on the surface are formed into a rectangular shape in plan view with a length of 1 m or less on both the horizontal and vertical sides. Then, two or more types of end plate pieces having different colors are produced by impregnating the paint into the interior by a reduced pressure press impregnation method, and then two parallel sides of the rectangular end plate pieces and the acute angle of inclination of the single-edged gradient surface shaved with formed on each of the two sides, to produce a single plate piece member, then the slope of the color difference is 2 or more units plate piece material The surfaces are bonded to each other, and the sloped surfaces are bonded to each other so that the color change boundary portions are shifted to the left and right on the surface and the back surface, and the colors of the adjacent unit plate pieces are alternately switched. as by continuously sequentially in series form to produce a fixed-length band plate-shaped intermediate member, then, the belt-shaped Between material was cut and divided into small width dimension with a plurality of rotary blades which are parallel to parallel while feeding in the longitudinal direction, to prepare a small strip sticks, to hold the state of the grain before cutting of the intermediate member the small strip temporarily secured while maintaining the order of arrangement of sticks, then placed in correspondence of the yarn to each of the change boundary is the method of the blind weaving the small strip sticks at the yarn to .
Further, a method of forming the above SL inclination angle 12 ° or less 5 ° or more.

In addition, a plurality of thin plate-like impregnated materials made of natural wood having a grain on the surface are formed in a rectangular shape in plan view with both the horizontal and vertical lengths of 1 m or less, and under reduced pressure and pressure impregnation, Two or more types of end plate pieces of different colors are produced by impregnating the paint to the inside. Next, an uneven comb tooth side portion is formed on each of two parallel sides of the rectangular end plate piece. Forming the unit plate piece material, and then meshing and bonding the above comb tooth side portions of two or more kinds of unit plate piece materials having different colors to each other by bonding the comb tooth side portions to each other. In order to form a wavy curved color change boundary portion and to successively switch the color of adjacent unit plate piece materials alternately in series to produce a standard strip plate-like intermediate material, and then The plate-shaped intermediate material is cut and divided into small widths with a plurality of rotary blades arranged in parallel while feeding along the longitudinal direction. The comb teeth forming the small band-like ridges and temporarily fixing them while maintaining the order of the small band-like ridges so as to maintain the state of the grain before cutting the intermediate material, and then forming the change boundary portion This is a method in which weaving yarns are arranged so as to be in contact with each of the crests and troughs of the side portions, and the small band-like knives are woven with the weaving yarns so as to be slender .

  According to the method for producing a wooden sudder of the present invention, checkered patterns and the like having different colors can be drawn easily and beautifully. Moreover, a scrap material (which has not been used in the past) can be used. In addition, a pattern can be formed by utilizing the natural grain.

  FIG. 1 shows a wooden sudder made using the first embodiment of the present invention. This wooden sudare has a checkered pattern of two colors. The two types of colors are, for example, brown and beige. In the drawings of the present invention, the paint X is indicated by dotted shading (FIG. 3), and the portion colored by the paint X is indicated by dotted shading. When the two different colors are used, the darker one is indicated by dotted shading.

Next, a method for producing this wooden sudare will be described. A plurality of pieces of rectangular end plate 1 made of natural wood as shown in FIG. 2 are impregnated in advance with a paint X (see FIG. 3) by a reduced pressure press impregnation method, so that the colors 2 are different. Make more than the kind. The end length plate piece 1 is made of a material, for example. A “rectangular end plate piece” is defined as a rectangular plate piece having a length dimension of both the horizontal side L ₁ and the vertical side L ₂ of 1 m or less. The reduced pressure press impregnation method is a method in which the coating material X and / or the disaster prevention agent B is vacuum impregnated, and then pressurized to sufficiently impregnate the interior of the material to be impregnated (end length plate piece 1). For example, as shown in FIG. 3, the container 3 containing the paint X and / or the disaster prevention agent B is placed in the casing 14, and the container 3 is vacuum-impregnated with a plurality of end plate pieces 1 and then pressurized. . Even if the surface 4 of the end plate piece 1 is finished with a sander or the like by the pressure and pressure impregnation method, the color does not partially change, and the grain of the surface 4 is beautiful. After the pressure and pressure impregnation method, the end plate piece 1 is dried. The thickness dimension (not shown) of the end plate piece 1 after drying is equal to the thickness dimension T of the jaw 8 (see FIGS. 1 and 9 to 11, which will be described later).

  As shown in FIG. 4, two parallel sides of a natural wood rectangular end plate piece 1 (see FIG. 2) are sharpened with an acute inclination angle θ to form a two-sided gradient surface (inclined surface) 5 on two sides. The unit plate piece material 6 is produced. The acute inclination angle θ is formed to be 5 ° or more and 12 ° or less. When the inclination angle θ is less than 5 °, it is difficult to form and the distance between a pair of adjacent weaving yarns 12 becomes wide, and the appearance deteriorates. When the inclination angle θ exceeds 12 °, the bonding area (of the unit plate piece material 6 and the unit plate piece material 6 in the next process) becomes small, and the bonding strength becomes small. Desirably, the inclination angle θ is 6 ° or more and 10 ° or less. For example, the inclination angle θ is formed at 8.8 °. When the thickness dimension T of the jaw 8 (see FIGS. 1 and 9 to 11) is small, it is preferable to set the inclination angle θ small. A sufficient adhesion area can be obtained. When the thickness dimension T of the jaw 8 is large, it is preferable to set the inclination angle θ large. No extra glue is required.

  Next, as shown in FIG. 5 and FIG. 6, the unit strip pieces 6 having different colors are successively continued by bonding of the gradient surfaces 5 and 5 (joined by a scarf joint using an adhesive). A plate-like intermediate material 7 is produced. Thereafter, as shown in FIG. 7, the strip-shaped intermediate material 7 is cut and divided into small widths w along the longitudinal direction (cut) to produce a small strip-like string 8 (see FIG. 9). Specifically, the intermediate member 7 is cut and divided along the longitudinal direction simultaneously with a plurality of rotary blades (cutters) 10 fixed in parallel to the rotary shaft 9 as shown in FIGS. An arrow Y in FIG. 7 indicates the feeding direction of the intermediate material 7. As shown in FIG. 9, after the intermediate material 7 is divided, in order to maintain the order in which the small band-like ridges 8 are arranged (that is, to keep the grain before cutting), for example, adhesion (adhesion) with tape 11 ) And fix it.

  The small band-like knives 8 are woven with the weaving thread 12 as shown in FIGS. At this time, the weaving thread 12 for weaving the small band-like string 8 is arranged correspondingly to the color change boundary part 13 due to the adhesion between the gradient surfaces 5 in the string 8. That is, the position is shifted left and right by a small width W on the surface 15 side and the back surface 16 side. Therefore, there are two woven yarns 12.

  The width dimension W in the front view (direction seen from the direction orthogonal to the plane of FIG. 1) of the color change boundary portion 13 on the surface 15 side and the surface 16 on the back side is set to 6 mm to 17 mm. Desirably, the width dimension W is set to 8 mm or more and 12 mm or less.

  Next, a second embodiment will be described. FIG. 12 shows a wooden sudder produced using the second embodiment. As shown in FIG. 13, first, the wooden sudare is manufactured by forming the concave and convex comb teeth on the parallel two sides 2 and 2 (see FIG. 2) of the rectangular end plate 1 of natural wood (see FIG. 2). The side part 17 is formed and the unit plate piece 6 is produced. Next, as shown in FIG. 14, the unit plate pieces 6 having different colors are successively continued by mutual meshing and bonding of the comb tooth side portions 17 (joined by finger joints using an adhesive). A strip-like intermediate material 7 is produced. Thereafter, the strip-shaped intermediate material 7 is cut and divided into small widths w (see FIG. 12) along the longitudinal direction to produce the small strip-shaped chin 8.

The weaving thread 12 for weaving the small band-like string 8 is arranged corresponding to the color change boundary part 13 due to the mutual bonding of the comb tooth parts 17 in the string 8. For example, as shown in FIG. 12, the woven yarn 12 is disposed so as to be in contact with each of the crests and troughs of the comb tooth side portion 17.
Other configurations (for example, the plurality of end plate pieces 1 are preliminarily impregnated with the paint X by a reduced pressure press impregnation method to produce two or more types having different colors) This is the same as the first embodiment.

  In the present invention, the design can be changed. For example, the two colors of the checkered pattern may be a combination other than brown and beige, for example, indigo color and natural wood color. . That is, some of the “two or more types of different color” end length plate pieces 1 may be natural wood colors (uncolored). Further, the design may be a pattern other than the checkered pattern. For example, the unit plate pieces 6 of three kinds of colors may be irregularly arranged. Further, the woven yarn 12 may be disposed not only at the color change boundary portion 13 but also at other positions. Further, in the second embodiment, it is preferable that the right and left end edges are cut so as to be straight lines, and the woven yarn 12 in the vicinity thereof is disposed slightly inward in the left-right direction as compared with the state of FIG. Further, the position at which the weaving yarn 12 is disposed in the second embodiment may be disposed in an intermediate zone between the straight lines in contact with the crests and troughs of the comb tooth side portion 17.

  As described above, according to the present invention, the parallel two sides 2 and 2 of the rectangular end plate piece 1 made of natural wood are sharpened with an acute inclination angle θ, and the single-edged gradient surface 5 is formed into two sides 2 and 2. Each unit plate piece 6 is formed on each, and then the unit plate pieces 6 of different colors are successively joined by the adhesion of the gradient surface 5 to produce the standard strip plate-like intermediate material 7. Thereafter, the band plate-like intermediate material 7 is cut and divided along the longitudinal direction into a small width w to produce a small band-like string 8, and a weaving thread 12 for weaving the small band-like line 8 into a sled In this case, the gradient surfaces 5 are disposed corresponding to the color change boundary portions 13 due to the mutual adhesion, so that it is possible to use a scrap material (which has not been used in the past). For example, if a large plate is removed from the edge, there are many cases where the end plate 1 has a small area S (see FIG. 2). Since the plate piece 1 can be easily obtained, such an end length plate piece 1 can be skillfully connected and used.

  In addition, a pattern can be formed by utilizing the natural grain. For example, checkered sudare can be produced. At this time, the grain is beautiful. Moreover, the amount of the adhesive can be reduced as compared with the case where the pattern portion is stuck on the entire surface of the single plate. Further, the color change boundary portion 13 can be hidden by the woven yarn 12, which is preferable in terms of aesthetics.

Further, since the plurality of end plate pieces 1 are preliminarily impregnated with the paint X by the pressure-and-pressure impregnation method to produce two or more types having different colors, a pattern such as a checkered pattern is formed. It can look beautiful. Moreover, even if the surface is finished by polishing or the like, since the inside is the same color, color unevenness does not occur.
Further, since the inclination angle θ is 5 ° or more and 12 ° or less, the unit plate pieces 6 can be appropriately bonded to each other, and the waste of the adhesive can be eliminated.

  In addition, an uneven comb tooth side portion 17 is formed on two parallel sides 2 and 2 of a rectangular end-cut plate piece 1 made of natural wood, and a unit plate piece material 6 is produced. The strip material 6 is successively made continuous by mutual meshing and bonding of the comb tooth side portions 17 to produce the fixed band plate-like intermediate material 7, and then the band plate-like intermediate material 7 is made to have a small width w along the longitudinal direction. The woven yarn 12 for weaving and dividing the small band-like string 8 into a sled is obtained by cutting and dividing the small band-shaped string 8, and the color change boundary part 13 by bonding the comb tooth side parts 17 to each other. Therefore, it is possible to use a scrap material (which has not been used in the past). For example, if a large plate is removed from the edge, there are many cases where the end plate 1 has a small area S (see FIG. 2). Since the plate piece 1 can be easily obtained, such an end length plate piece 1 can be skillfully connected and used.

  In addition, a pattern can be formed by utilizing the natural grain. For example, checkered sudare can be produced. Also, the grain is beautiful. Also, the pattern can be expressed beautifully. Moreover, the amount of the adhesive can be reduced as compared with the case where the pattern portion is stuck on the entire surface of the single plate. Further, the bonded portion can be reinforced by the weaving thread 12.

  Further, since the plurality of end plate pieces 1 are preliminarily impregnated with the paint X by the pressure-and-pressure impregnation method to produce two or more types having different colors, a pattern such as a checkered pattern is formed. It can look beautiful. Moreover, even if the surface is finished by polishing or the like, since the inside is the same color, color unevenness does not occur.
