Description

  The present invention relates to a method for producing a decorative material used for a fence, a step board, a skirting board, a door and the like in a building such as a house.

  For some time, decorative materials used for eaves, step boards, skirting boards, doors, and the like in buildings of various forms such as houses have been developed. For example, in Patent Document 1, as shown in FIG. In addition, a flexible sheet 2 such as a non-woven fabric or synthetic resin sheet made of polyester or the like is pasted on the surface of a single sheet material 1, and the natural wood is thinned on the surface of the flexible sheet 2. While sticking the projected plate etc. as the surface material 3, the bottom is V toward the flexible sheet 2 from the back surface of the plate material 1 (the surface opposite to the surface on which the flexible sheet 2 or the like is adhered). A decorative material 5 (before bending) in which a letter-shaped cutout groove 4 is formed is disclosed. Then, as shown in FIG. 6B, the decorative material 5 is formed by bending the flexible sheet 2 so that the notch groove 4 is closed using the flexible sheet 2 as a guide.

Japanese Utility Model Publication No. 54-109317

  However, since the decorative material 5 of the prior art performs the bending process including the flexible sheet 2 and the surface material 3, the surface material 3 is flexible enough to withstand the bending process. There is a problem that the material selection has to be narrow, and the V-cut is made on the single plate 1, so both sides of the notch groove 4 are naturally the same plate, for example, the bending position It was not possible to meet the demand to change the thickness on both sides of the border.

  In addition, for example, a decorative material 5 attached to the top surface where a large load may be applied by a person stepping on, such as a saddle material, and a decorative material 5 attached to a side surface where there is no such risk, Naturally, the required durability is different. However, in the decorative material 5 of Patent Document 1, the thickness and material of the base material (= plywood plate material 1) are changed between the portion disposed on the top surface of the eaves and the portion disposed on the side surface, Alternatively, since the durability of the surface material 3 cannot be changed, the material required for the decorative material 5 to be disposed on the top surface must be selected, and as the decorative material 5 to be disposed on the side surface, There was a problem of excessive quality. Furthermore, in recent years, the supply of large-diameter trees has decreased, and it has become difficult to supply a single woody veneer veneer. ing.

  Furthermore, cosmetic materials are used in large quantities in buildings such as houses, and development of a method for producing cosmetic materials with less effort has been awaited.

  The present invention has been developed in view of such problems of the prior art. Therefore, the main problem of the present invention is a method for producing a cosmetic material that can be produced with good productivity, can be selected and varied in thickness and material on both sides of the corner, and can be produced in a large amount with less labor. Is to provide.

“A method for manufacturing the decorative material 10 by cutting the third plate member 50 between the grooves 30 and 32”.

  According to the present invention, in addition to the operational effects of the manufacturing method according to the first aspect, a material with poor flexibility can be used as the surface material 18.

The invention described in claim 3 relates to an improvement of the manufacturing method of the decorative material 10 described in claim 1,
“The surface handle of the third plate member 50 and the surface handle of the first and second plate members 12 and 14 are different from each other”.

The invention described in claim 4 relates to an improvement of the manufacturing method of the decorative material 10 described in claim 2,
“The surface pattern of the surface material 18 provided on the third base member 52 and the surface pattern of the surface material 18 of the first and second plate members 12 and 14 are different from each other”.

  According to these inventions, it is possible to provide the decorative material 10 having different surface patterns on both sides of the corner portion 26. Further, the surface handle of the third plate member 50 or the surface handle of the surface member 18 provided on the third base member 52 may be different from each other on both sides of the cut position. Thereby, the surface handle of the first and second plate members 12 and 14, the part of the third plate member 52 attached to the first plate member 12 and the surface handle of the other portion of the third plate member 52 attached to the second plate member 14 are all. The decorative material 10 which can be made different and whose surface patterns do not overlap each other can be manufactured.

The invention described in claim 5 relates to an improvement in the manufacturing method of the decorative material 10 according to any one of claims 1 to 4,
“Before contacting the first and second plate members 12 and 14 against the third plate member 50, both side surfaces 50a and 50b of the third plate member 50 and the third plate member 50 of the first plate member 12 are contacted. A tapered surface 60 that forms an acute angle with the surfaces of the plate members 12, 14, and 50 having the surface is formed on at least one of the contact side surface 12 a and the side surface 14 a of the second plate member 14 that contacts the third plate member 50. It is characterized by.

  According to the present invention, the tapered surface 60 is formed on at least one surface of the contact surface between the first plate member 12 and the third plate member 50 and / or the contact surface between the second plate member 14 and the third plate member 50. Therefore, even if foreign matter or the like is present on the contact surface on which the tapered surface 60 is formed, when the plate materials are brought into contact with each other, the foreign matter or the like is released on the tapered surface 60 to thereby contact the plate materials. The contact edge can be contacted accurately, and then the contact surfaces 22 and 23 are cut to form the grooves 30 and 32, thereby eliminating the influence of foreign matter and the like, and suppressing the occurrence of defects and the production yield. Can be dramatically improved.

The invention described in claim 6 relates to an improvement in the method for manufacturing the decorative material 10 according to any one of claims 1 to 5,
“After the side surfaces 12a and 14a of the first plate 12 and the second plate 14 are brought into contact with both side surfaces 50a and 50b of the third plate 50, respectively, until the grooves 30 and 32 are closed. A tape material 28 having flexibility is applied from the surface of the first plate member 12 to the surface of the third plate member 50 and from the surface of the second plate member 14 to the surface of the third plate member 50,
It is bent at the groove bottom portions 30a and 32a of the grooves 30 and 32, and the plate members 12, 14, and 50 are fixed to each other, and then the tape material 28 is peeled off. "

  According to the present invention, when the tape material 28 is bent as a guide, a pressing force is generated in the stretched portion of the tape material 28 in a direction in which the butt ends of the bent portions are brought into close contact with each other. As a result, it is possible to manufacture the cosmetic material 10 having a good appearance in which the end portions of the plate members 12, 14, and 50 are accurately matched. In particular, it is more effective when the V-shaped grooves 30, 32 reach the surface and the tips of the plate members 12, 14, 50 are thinned. The tape material 28 also has a role of preventing the adhesive 36 attached to both grooves 30 and 32 from protruding to the surface.

The invention described in claim 7 relates to the improvement of the “method for producing the decorative material 10” described in claim 6,
“Attaching the tape material 28 is performed in a state in which the surface of the third plate material 50 in contact with each other and at least one surface of the first plate material 12 and the second plate material 14 form an obtuse angle,
After the tape material 28 is applied, the grooves 30 and 32 are formed after the tape material 28 is expanded so that the contact angle becomes larger.

  According to the present invention, each plate 12 in a state where the surface of the third plate 50 and at least one surface of the first plate 12 and the second plate 14 form an obtuse angle (an angle greater than 90 degrees and less than 180 degrees). , 14, 50 on the surface of the tape material 28, the two plate materials 12, 50 (when the first plate material 12 and the third plate material 50 are abutted at an obtuse angle so that the contact angle becomes larger. The same shall apply hereinafter.) When it is stretched and stretched, a force to shrink is generated. Since both the board | plate materials 12 and 50 are pressed more strongly by this contraction force, the front-end | tip parts of both the board | plate materials 12 and 50 match more accurately, and the cosmetic material 10 with a more attractive appearance can be manufactured.

The invention described in claim 8 relates to an improvement in the method for manufacturing the decorative material 10 according to claim 2 or 4,
“The first to third plate members 12, 14, and 50 have a desired surface pattern by ink jet printing on paper having an ink receiving layer that is previously attached to the surface of the base member 13, 15, or 52 as the surface member 18. Is formed ".

The invention described in claim 9 relates to an improvement in the manufacturing method of the decorative material 10 according to claim 8,
“A transparent paint is applied to the surface of the paper on which ink-jet printing has been performed”.

  A general printing sheet requires printing lots of thousands to tens of thousands of meters printed on a rotary press. If it is used for products with large areas such as wall materials and flooring, there is no problem even if the printing lot is large in this way, but cosmetics with a small construction area such as fences, treads, baseboards, etc. In the case of using a printing sheet for a large number of printing lots, it was not possible to prepare many kinds of surface patterns and there was no freedom of selection.

  However, in the invention described in claim 8, since the decorative pattern of the surface material 18 can be printed in a smaller area (for example, in units of 3 × 6 plates) using inkjet printing, various types of surface patterns are prepared. However, it is possible to design products with a low degree of inventory risk and a high degree of freedom.

  In addition, when the surface material 18 on which the decorative pattern is formed in advance is adhered to each of the base materials 13, 15, 52, curing is required until the adhesive that adheres the surface material 18 is solidified. Therefore, there has been a problem that productivity cannot be improved.

  However, since the paper having the ink receiving layer is preliminarily pasted and integrated on the surface of each of the base materials 13, 15, 52 and printing is performed as necessary, the curing period as described above becomes unnecessary, The cosmetic material 10 can be produced with a short delivery time.

  Ink jet printing may be performed using a facility capable of printing on a general thick plate, and it is preferable to use UV colored ink having excellent water resistance.

  Further, as described in claim 9, immediately after ink jet printing, a transparent paint is applied to the surface of ink jet printing (undercoating), thereby transporting when applying a tape or grooving in a later step. It can prevent the damage by.

  As such a transparent paint, a general paint for acrylic, urethane or the like is used, but an undercoat containing a so-called antifriction agent such as white alumina or green carbon is preferably used. Needless to say, the surface of the undercoated transparent coating may be further coated with a transparent coating (overcoating) so as to erase the scratches generated during transportation.

  According to the present invention, it is possible to selectively use a plurality of types of base materials having different materials such as plate thickness, hardness, and strength on both sides of a corner portion depending on the location, and when using a surface material, It was possible to select a material with poor flexibility and to provide a method for manufacturing a cosmetic material that can be manufactured in a large amount with less labor.

It is a figure which shows the modification (U-shaped decorative material) of the manufacturing method of the decorative material which concerns on this invention. It is a figure which shows a prior art.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The first plate member 12, the second plate member 14, and the third plate member 50 used for manufacturing the decorative material 10 are the first base member 13, the second base member 15, and the third base member 52, respectively, or If necessary, a surface material 18 may be provided on the surface of each base material 13, 15, 52 via an adhesive layer 16.

  The first base material 13 and the second base material 15 shown in FIG. 1 are wood base materials formed of wood base materials, and the wood base materials include solid wood, plywood, MDF, HDF, hard A board, a particle board, an insulation board, etc. can be mentioned. In addition, you may set so that the thickness of the 1st board | plate material 12 and the thickness of the 2nd board | plate material 14 may mutually differ.

  The third base material 52 is formed of a wood fiber base material. As the wood fiber base material, a medium specific gravity fiber board, a high specific gravity fiber board, MDF, etc., in which the wood fiber is solidified with an adhesive and made into a plate shape or a prismatic shape (a product obtained by cutting a plate-like wood fiber base material). It is possible to use a dry-formed wood fiber board such as HDF, or a wet-made wood fiber board such as a hard board. Of course, a woody base material may be used for the third base material 52 in the same manner as the first base material 13 and the second base material 15.

  The adhesive layer 16 is a layer of an adhesive having a thickness of 0.05 mm to 0.15 mm provided on the surface of each of the base materials 13, 15, 52 described above, and constitutes the adhesive layer 16. Adhesives include vinyl acetate resin, water-based vinyl urethane resin, urethane foam resin, silicon resin, hot melt resin, PUR (Poly Urethane Reactive) hot melt resin (that is, "PUR adhesive"), etc. Can be mentioned. When the colors of the substrates to be brought into contact with each other are different from each other, the adhesive layer 16 is colored by adding a pigment to the adhesive according to the surface color of the surface material 18, and the colors of the substrates are different. The difference may be inconspicuous. Of course, the adhesive layer 16 may be formed of a colorless and transparent adhesive.

  As the surface material 18, a sheet material such as a veneer, paper, resin-impregnated paper, poly sand paper, or a resin sheet is used, and any sheet material can be used regardless of the flexibility of the material. . In addition, when using sheet materials other than the veneer, it is necessary to use the one with a grain pattern designed on the surface based on a highly rare and beautiful grain printed with gravure wheel printing technology etc. Is preferred. Moreover, you may use what performed the inkjet printing as needed to the paper provided with the ink receiving layer, or the poly sand paper.

  Of course, as the surface material 18, DAP-impregnated paper, melamine-impregnated paper, or the like may be provided on the surface of each base material 13, 15, 52 without providing the adhesive layer 16. Further, a thermosetting resin-impregnated decorative paper having poor flexibility can be used as the surface material 18.

  The surface pattern of the surface material 18 provided on the surface of each base material 13, 15, 52 may be the same or different from each other, but at least the surface material 18 of the third base material 52, It is preferable to make the surface pattern different between the surface materials 18 of the first and second base materials 13 and 15. Thereby, the decorative material 10 from which the surface pattern differs on both sides of the corner | angular part 26 can be provided. Moreover, when the surface material 18 is not provided, it is preferable that the surface patterns of the base materials 13, 15, and 52 are made different as described above.

  Next, using the first plate member 12, the second plate member 14, and the third plate member 50 described above, the surface member 18 may not be used, mainly the “decorative material 10 having the surface member 18” that is a finished product. In addition, a procedure for manufacturing without using the tape material 28 will be described.

  First, the 1st board | plate material 12, the 2nd board | plate material 14, and the 3rd board | plate material 50 in which the surface material 18 was provided through the adhesive bond layer 16 are prepared (FIG.1 (a)), and each board | plate material 12,14,50 is prepared. The third plate member 50 is disposed between the first plate member 12 and the second plate member 14 with the surface being flush, and then the both sides 50a, 50b of the third plate member 50 are placed on the first plate member 12. The side surface 12a and the side surface 14a of the second plate member 14 are abutted and brought into contact with each other (FIG. 1B).

  After the plate members 12, 14, and 50 are brought into contact with each other, the contact surfaces 22 and 23 appearing on the back surfaces of the plate members 12, 14, and 50 are maintained in a V-shape (not shown) while maintaining the contact state. After matching the cutting edge of the rotary saw, it is cut out by the rotary saw to form V-shaped first and second grooves 30 and 32 that match the shape of the rotary saw (FIG. 1 (c)). The first groove 30 is formed from the first plate member 12 to the third plate member 50, and the second groove 32 is formed from the second plate member 14 to the third plate member 50. In addition, the V-shaped second groove 32 is formed at a position separated from the first groove 30 at the same time as the first groove 30 or before and after the first groove 30.

  As a means for maintaining the contact state, a method of completely fixing the plate members 12, 14, and 50 can be considered. Specifically, a method of mechanically fixing with a clamp, a pressing machine, a large saw-like fixing tool (so-called gang), an air adsorption, an adsorbent having an adsorbent on the surface, an adhesive having an adhesive on the surface The method of fixing by fixing means, such as these, is mentioned. Further, when the plate members 12, 14, and 50 are brought into contact with each other, the contact state may be maintained by bonding the side surfaces 12a and 50a and 14a and 50b that are in contact with each other with a hot-melt adhesive or the like. When using a transporter that may damage the surface of the plate material, such as an escape, it is preferable to contact the escape with the back side.

  Further, in order to cope with various width dimensions and thickness dimensions, it is desirable to suppress horizontal and vertical lifting using an air damper, an oil damper, a spring cushion, or the like. When using a horizontal pressing force, the plate members 12, 14, and 50 may be urged against each other, and a side surface opposite to the contact side surface of one plate material is a so-called ruler surface, and the ruler is concerned. The surface may be urged and abutted against the surface.

  Furthermore, it is also possible to carry out grooving by conveying the plate members 12, 14, 50 while maintaining the contact state with the fixed rotary saw. In this case, a method of conveying while mechanically abutting with a clamp, a pressing machine, an escaper, etc., a method of conveying while abutting with a fixing means such as air adsorption, an adsorber, an adhesive, or the like, For example, a method may be used in which 14, 50 is conveyed while being urged against the ruler surface as described above, using an air damper, an oil damper, a spring cushion, or the like.

  In any case, in order to improve the groove machining accuracy, it is preferable to eliminate vertical blur due to cutting using a vertical pressing force. In this case, it is preferable to press the position as close as possible to the portion to be cut in order to improve the groove processing accuracy.

  The first and second grooves 30, 32 have groove bottom portions 30 a, 32 a that coincide with the contact surfaces 22, 23, and each base material 13, 15, 15 constituting each plate member 12, 14, 50. 52 (or in this case, the back surface of the surface material 18 is not cut), or the surface of the surface material 18 beyond each base material 13, 15, 52 (that is, each plate material). 12, 14, and 50) or at least near the front side thereof (that is, in this case, at least the butt end portion of the surface material 18 of the third plate 50 is cut and thinned). ing.).

  In the illustrated embodiment, the first and second grooves 30 and 32 are formed into “V-shaped grooves” that are cut so as to be applied not only to the third plate member 50 side but also to the first plate member 12 and the second plate member 14 side. (The shape of the first and second grooves 30, 32 matches the shape of the rotary saw).

  In addition, the grooves 30 and 32 in the present embodiment are formed so that the lengths of the two sides 13a and 52a and 15a and 52b in the sectional view coincide with each other. At this time, as shown in FIG. 1 (e), the inner edge of the corner portion 26 becomes a right angle, and the decorative material 10 (FIG. 1 (f)) that can be attached to the surface of the square pillar material can be formed (of course, of course). , It may be a V-shaped groove in which the length of each corresponding side is different).

  The position of the groove bottom portions 30a, 32a is defined as “the surface of each plate member 12, 14, 50 or near the front thereof” because the position of the groove bottom portions 30a, 32a of each groove 30, 32 is the respective plate members 12, 14, This is to prevent protrusion from the surface of the plate 50, and in consideration of the accuracy of groove processing (about ± 0.03 mm), the position is set to a position slightly behind the surface of each plate 12, 14, 50. It is preferable to set.

  Also, the tip is V-shaped (as will be described later, adhesive 36 is attached to the V-shaped grooves 30 and 32, so in this embodiment, two 46 ° saw blades are used in combination with one blade. When the plate members 12 and 14 are bent at right angles, a space for the adhesive 36 is secured.) Using the rotary saw formed in both the grooves 30 and 32, each of the grooves 30 and 32 is processed into a “V shape. By forming it in the “grooves”, the angle of the inclined surface to be formed can be made accurate, and when the plate members 12, 14, 50 are joined, it is possible to achieve beautiful joining with no gaps in the joining parts. . Of course, a so-called router machine or the like may be used instead of the rotary saw.

  While the plate members 12, 14, and 50 are kept in contact with each other (at this stage, as shown in the figure, when the surface member 18 is not used, the surface side ends of the plate members 12, 14, and 50, or When the surface material 18 is used, the surface materials 18 are in contact with each other.), A hot melt adhesive, a PUR hot melt adhesive, and an aqueous vinyl urethane adhesive are attached to the surfaces of the grooves 30 and 32. Adhesive 36 such as an adhesive, a vinyl acetate adhesive, or a urethane adhesive is attached (FIG. 1 (d)), and then both grooves 30, 32 are closed to connect the plate members 12, 14, 50 to each other. It is made to adhere (FIG.1 (e)). Finally, the third plate member 50 is cut between the grooves 30 and 32 to complete the two decorative materials 10 (FIG. 1 (f)).

  The adhesive 36 may be attached to both surfaces of the grooves 30 and 32 in the plate members 12, 14, and 50, or may be attached to only one surface of the grooves 30 and 32.

  Moreover, since each board | plate material 12,14,50 is comprised as a mutually separate member, when these are fixed and it tries to comprise the decorative material 10, the corner | angular part (the groove | channels 30 and 32 of the decorative material 10 was closed). There is a possibility that the adhesive 36 protrudes from the surface of the mating surfaces. In such a case, the adhesive 36 has the same color as the color of the surface of each base material 13, 15, 52 (when the surface material 18 is not attached) or the color of the surface of the surface material 18 (when the surface material 18 is attached), or By coloring in a similar color, the protruding adhesive 36 is less noticeable, which is preferable.

  A plurality of types of adhesives 36 may be used in combination. For example, water-based vinyl urethane adhesives are excellent in adhesive strength but require a little time to cure, so although they are slightly inferior in adhesive strength, PUR hot-melt adhesives and water-based vinyl urethane are quick in time to cure. By using the adhesives together, the first plate member 12, the second plate member 14, and the third plate member 50 are first fixed with a PUR hot melt adhesive to prevent undesired misalignment or the like. By curing the aqueous vinyl urethane adhesive over time, the plate members 12, 14, and 50 can be firmly bonded without being displaced.

  Since the first to third plate members 12, 14, 50 are separate members as described above, the first to third plate members 12, 14, 14 having different surface patterns and materials (hardness, plate thickness, etc.) are different from each other. 50 can be used to manufacture the decorative material 10. Further, when the surface material 18 is used, a material having poor flexibility can be used as the surface material 18.

  As shown in FIG. 2, in the stage before the first and second plate members 12 and 14 are brought into contact with the third plate member 50, both side surfaces 50 a and 50 b of the third plate member 50 and the third plate member 50 of the first plate member 12. A taper surface 60 that forms an acute angle with the surfaces of the plate members 12, 14, and 50 having the surface is formed on at least one of the side surface 12a that contacts the third plate member 50 of the second plate member 14 and the side surface 14a that contacts the third plate member 50 of the second plate member 14. (See FIG. 2A. In this embodiment, tapered surfaces 60 are formed on both side surfaces 50a and 50b of the third plate member 50). The acute angle formed by the surface of the third plate member 50 and the tapered surface 60 is greater than the angle (acute angle) formed by the surface of the third plate member 50 and the surface formed by the V-shaped groove 30 or 32 formed later. large.

  When the side surfaces 12a, 14a of the first and second plate members 12, 14 are brought into contact with the third plate member 50 (in this case, as shown in FIG. 2 (b), the surface side of each plate member 12, 14, 50 is If there is a foreign object such as foreign matter between the side surfaces (12a and 50a, or 14a and 50b), the surfaces of the plate members 12, 14, and 50 do not come into contact with each other correctly ( In other words, the V-shaped grooves 30 and 32 are formed in a separated state, causing defects and reducing productivity. However, as described above, by forming the tapered surface 60, foreign matters Etc., even when both plate materials (12 and 50, 14 and 50) are brought into contact with each other, the edges of the surfaces of both plate materials (12 and 50, 14 and 50) are released by escaping the foreign matters. Can be brought into contact with each other accurately, and the occurrence of defects Suppressed and production yield can be remarkably improved. Of course, the same effect can be obtained when the tapered surface 60 is formed on the side surface 12a of the first plate member 12 or the side surface 14a of the second plate member 14.

  Further, as shown in FIG. 4C, a side surface 12b opposite to the side surface 12a in contact with the third plate material 50 in the first plate material 12 is formed on the ruler surface 62, and the first When the third plate member 50 and the second plate member 14 are brought into contact with the plate member 12, the third plate member 50 in which the tapered surface 60 is formed on the side surface 12a of the first plate member 12 positioned with the ruler surface 62 as a reference. The side surface 50a may be pressed.

  Thereby, since the 3rd board | plate material 50 and the 2nd board | plate material 14 can be correctly contact | abutted with respect to the 1st board | plate material 12 correctly positioned on the basis of the ruler surface 62, generation | occurrence | production of a defect can be suppressed and a production yield can be suppressed. Further improvement can be achieved.

  Next, the case where it manufactures using the tape material 28 is demonstrated. As shown in FIG. 3, the side surfaces 12a, 14a, 50a of the plate members 12, 14, 50 are brought into contact with each other and are flush with each other between the first plate member 12 and the third plate member 50, and the second plate member 50. A tape material 28 having flexibility is attached to the surface of each plate member 12, 14, 50 between the plate member 14 and the third plate member 50 (FIG. 3B), and groove processing is performed in the same manner as described above (FIG. 3). (C)) After adhering the adhesive 36 to the grooves 30 and 32 (FIG. 3D), the plate members 12, 14, and 50 are fixed to each other by bending with the tape material 28 as a guide (FIG. 3). (E)) After the third plate member 50 is cut between the grooves 30, 32, the tape member 28 is finally peeled off (FIG. 3 (e)).

  The timing of attaching the tape material 28 is at any stage from when the plate members 12, 14, 50 are brought into contact with each other until the grooves 30, 32 formed on the contact surfaces 22, 23 are closed. Anytime if you want. Further, the tape material 28 may be attached separately between the first plate material 12 and the third plate material 50 and between the second plate material 14 and the third plate material 50 as shown in the figure, or the first plate material 28 The second plate member 14 may be pasted from 12 to the third plate member 50.

  As the tape material 28, if it is a general thin tape having an adhesive strength that does not peel off from each of the base materials 13, 15, 52 or the surface material 18 after the sticking process is completed, Any material can be used regardless of whether it is made of vinyl or paper, but if the adhesive strength of the tape material 28 is too strong, the surface material 18 will be peeled off when the tape material 28 is peeled off. It should be noted that when the surface material 18 is used, the tape material 28 having an excessively strong adhesive strength should not be used. Therefore, what is used in order to peel off after sticking is preferable, and what is called a curing tape is used most suitably.

  Curing tape is a tape used for temporary fixing in construction or the like, and is a tape intended to be peeled off after being stuck for a certain period. For this reason, the adhesive tape is designed to be less likely to remain on the adherend, and is most suitable for use in the present production method. In addition, the general curing tape is considered to be easy to cut in the length direction and have strength in the width direction by making the cutting strength in the transverse direction significantly weaker than that in the length direction. When used in this production method, the contact strength between the plate materials can be ensured, and the transverse cut can be easily performed at the time of attachment. Such a method for producing a curing tape is disclosed in, for example, JP-A-58-52380 and JP-A-5-247421.

  In this way, the flexibility that is applied between the first plate member 12 and the third plate member 50 and between the second plate member 14 and the third plate member 50 is attached to the surface of each plate member 12, 14, 50. By bending the tape material 28 having a thickness, the front and rear end portions of the side surfaces 12a and 14a of the first and second plate members 12 and 14 and the thin front end portion of the third plate member 50 are kept in contact with each other while being adhered to each other. be able to. At this time, as already described, accurate tip contact is performed by the pressing force generated at the portion of the tape material 28 that is bent at the bent portion. In particular, it is more effective when the V-shaped grooves 30, 32 reach the surface and the tips of the plate members 12, 14, 50 are thinned. The tape material 28 also has a role of preventing the adhesive 36 attached to both grooves 30 and 32 from protruding to the surface. As described above, by using the tape material 28, it is possible to manufacture the cosmetic material 10 having a good appearance in which the end portions of both the plate materials 12 and 14 are accurately matched.

  Further, as shown in FIG. 4, the surface of the first plate 12 and the surface of the third plate 50 in contact with each other means an obtuse angle (an angle greater than 90 degrees and smaller than 180 degrees. The tape material 28 is applied in a state of forming the tape material 28 in the state of FIG. 4 (FIG. 4 (b)). After affixing 28, the grooves 30 and 32 may be formed after spreading so that the contact angle between the two plate members 12 and 50 becomes larger (FIG. 4C). In the present embodiment, the first plate member 12 and the third plate member 50 are in contact with each other at an obtuse angle, but of course, the second plate member 14 and the third plate member 50 may be in contact with each other at an obtuse angle. Both the plate member 12 and the second plate member 14 may be brought into contact with the third plate member 50 at an obtuse angle.

  As a result, the two plate members 12, 50 are brought into contact with the tape member 28 attached to the surfaces of the two plate members 12, 50 in a state where the surface of the first plate member 12 and the surface of the third plate member 50 form an obtuse angle. When both plate members 12, 50 are expanded so that the angle becomes larger (preferably, the angle between the surface of the first plate member 12 and the surface of the third plate member 50 is 180 degrees). The force to try to shrink arises. Since both the board | plate materials 12 and 50 are pressed more strongly by this contraction force, the front-end | tip parts of both the board | plate materials 12 and 50 match more accurately, and the cosmetic material 10 with a more attractive appearance can be manufactured.

  Further, as shown in FIG. 5, the fourth plate member 70 and the fifth plate member 72 are brought into contact with the side surfaces of the first plate member 12 and the second plate member 14 opposite to the contact with the third plate member 50, respectively. In the same manner as described above, after forming a V-shaped groove between the first plate member 12 and the fourth plate member 70 and between the second plate member 14 and the fifth plate member 72, bending is performed. After that (see FIG. 5A), after that, the third plate member 50 can be cut to form a substantially U-shaped decorative material 10 as shown in FIG. 5B. Of course, all the manufacturing methods described above including the use of the tape material 28 can also be applied to the manufacturing method of the U-shaped decorative material 10.

  In addition, as can be said for all of the above-described embodiments, a general printing sheet requires a printing lot in units of several thousand to several tens of thousands of m to be printed on a rotary press. If it is used for products with large areas such as wall materials and flooring, there is no problem even if the printing lot is large in this way, but cosmetics with a small construction area such as fences, treads, baseboards, etc. In the case of using a printing sheet for a large number of printing lots, it was not possible to prepare many kinds of surface patterns and there was no freedom of selection.

  Therefore, it is preferable to attach a paper having an ink receiving layer as the surface material 18 in advance to the surface of each of the base materials 13, 15, 52 and form a desired surface pattern on the surface of the paper by ink jet printing. . Using ink-jet printing, the decorative pattern of the surface material 18 can be printed in a smaller area (for example, 3 x 6 scale plate unit). This is because the design becomes possible.

  In addition, in the case where a surface material on which a decorative pattern has been previously formed is adhered to each of the base materials 13, 15, 52, curing is required until the adhesive 36 that adheres the surface material 18 is solidified. For this reason, there is a problem that productivity is not improved. However, as described above, paper having an ink receiving layer is bonded and integrated on the surfaces of the base materials 13, 15, and 52 in advance and printed as necessary. By performing the above, the curing period as described above becomes unnecessary, and it becomes possible to produce the cosmetic material with a short delivery time.

  Ink jet printing may be performed using a facility capable of printing on a general thick plate, and it is preferable to use UV colored ink having excellent water resistance.

  In addition, by applying a transparent paint to the surface of ink jet printing immediately after ink jet printing (undercoating), it is possible to prevent damage due to transport or the like when a tape is applied or grooves are processed in a subsequent process.

  As such a transparent paint, a general paint for acrylic, urethane or the like is used, but an undercoat containing a so-called antifriction agent such as white alumina or green carbon is preferably used. Needless to say, the surface of the undercoated transparent coating may be further coated with a transparent coating (overcoating) so as to erase the scratches generated during transportation.
