Description

Technical Field

[0001] The present invention relates to a jig for manufacturing a laminated tape and a method for manufacturing a laminated tape using the same.

Background Art

[0002] Calcium-based inorganic members such as concrete, cement, gypsum, and stone always have problems of aging deterioration such as weathering, pollution by moss, etc., or wear, cracking, peeling, etc. due to aging. Various repair techniques have been established and proposed.

[0003] On the other hand, in recent years, for example, a surface modification composition composed of a mixture of a resin having a silanol group or a group convertible to a silanol group, a water-soluble alkali silicate compound, and silica sand or calcium carbonate has been developed (Patent Document 1). Such a surface modification composition can provide a thick coating film on the calcium-based inorganic member, and in addition to repairing the above-mentioned aging deterioration, it can also impart new designability to the calcium inorganic member.

[0004] On the other hand, when arranging calcium-based inorganic members at a predetermined position in a building or the like, a large number of joints composed of straight lines parallel or intersecting each other may be provided between adjacent members. Joints may also be provided for the arrangement of wooden boards or wood-based boards. Such joints function as a cover for the joint part of the members and also play a role of imparting new designability to the entire arranged plane.

[0005] However, generally, complicated work is required to provide a predetermined joint while providing a coating film on a member. For example, this is because it is required to form a coating film while avoiding the joint part and separately arrange another material such as a caulking material at the joint part.

BEST MODE FOR CARRYING OUT THE INVENTION

[0017] The present invention will be described with reference to the accompanying drawings. In addition, the configurations denoted by the same reference numerals common to all the following drawings are the same as those shown in the other drawings.

[0018] (1) Jig for manufacturing laminated tape As shown in FIG. 1, the jig 100 for manufacturing the laminated tape of the present invention includes a housing 110, a first tape roll 120, a second tape roll 130, a first support column 140, and a second support column 150.

[0019] (Housing) FIG. 2 is an exploded perspective view of the jig 100 for manufacturing the laminated tape shown in FIG. 1.

[0020] In Figure 2, the housing 110 comprises a main body cover 112 and a lid cover 114. Both the main body cover 112 and the lid cover 114 have a recessed shape on the inside, and can be joined together, for example by fitting, to form a single housing 110. The integrated main body cover 112 and lid cover 114 (i.e., housing 110) can house the first tape roll 120 and the second tape roll 130 inside.

[0021] The main body cover 112 and the lid cover 114 are made of a material having a predetermined strength, such as plastic, metal, wood, or composite material.

[0022] Examples of plastics include thermoplastic resins such as polyethylene, polypropylene, polyvinyl chloride, acrylonitrile butadiene styrene (ABS) resin, styrene resin, polycarbonate, and acrylic resin; and thermosetting resins such as epoxy resin; as well as combinations thereof.

[0023] Examples of metals include ferrous metals such as steel, tool steel, carbon steel, iron-containing alloys, and stainless steel; non-ferrous metals such as aluminum, nickel, magnesium, titanium, copper, and alloys containing these; and combinations thereof.

[0024] Examples of composite materials include fiber-reinforced plastics (FRP), fiber-reinforced metals (FRM), fiber-reinforced ceramics (FRC), metal matrix composites (MMC), wood-based resin compositions (e.g., wood powder-containing resin compositions), and combinations thereof.

[0025] In the present invention, for example, the lid cover 114 is made of a transparent material (e.g., polycarbonate, acrylic resin) so that the remaining amount of the first tape roll 120 and the second tape roll 130 inside the housing 110 can be easily checked by visual inspection. In the present invention, either the main body cover 112 or the lid cover 114, or both thereof, may be made of the transparent material. Alternatively, the transparent material may be placed in a small window portion (not shown) provided in at least one of the main body cover 112 or the lid cover 114.

[0026] The size of the main body cover 112 and the lid cover 114 is not particularly limited. For example, as shown in Figure 3, the main body cover 112 and the lid cover 114 have sufficient height (or depth) so that there is no gap between them when the first tape roll 120 and the second tape roll 130 are housed inside.

[0027] Referring again to Figure 2, the main body cover 112 and the lid cover 114 are provided with notches 162 and 164 in part so that when they are joined together they can form a single tape outlet 160. The tape outlet 160 is sized to allow the laminated tape 170 obtained using the first tape roll 120 and the second tape roll 130 to be pulled out from the inside of the housing 110 to the outside. A tape cutter (not shown) may be provided in the tape outlet 160.

[0028] In the present invention, for example, a lamination guide 116 may be provided inside the main body cover 112. The lamination guide 116 has an elongated shape which may be appropriately curved, and can assist in and reinforce the lamination and adhesion of the first tape 122 drawn from the first tape roll 120 and the second tape 132 drawn from the second tape roll 130. For example, in Figure 2, the lamination guide 116 is provided near a notch 164 inside the main body cover 112, and the first tape 122 drawn from the first tape roll 120 and the second tape 132 drawn from the second tape roll 130 are laminated so that the first tape 122 comes into close proximity to the shoulder portion 166 provided at the end of the lamination guide 116 on the side closer to the notch 164, and the second tape 132 comes into contact with the shoulder portion 166, causing the first tape 122 and the second tape 132 to come into contact with each other and adhere firmly to form a laminated tape 170.

[0029] Although Figure 2 shows an example in which the lamination guide 116 is provided inside the main body cover 112, the present invention is not limited to this. The lamination guide may be provided inside the lid cover 114 instead of the main body cover 112. Alternatively, the lamination guide may be a structure in which a protruding portion provided inside the main body cover 112 and the lid cover 114 respectively comes into contact with each other when the main body cover 112 and the lid cover 114 are brought together to form a single structure.

[0030] (First tape roll and second tape roll) In the laminated tape manufacturing jig 100 of the present invention shown in Figure 2, the first tape roll 120 and the second tape roll 130 are arranged in parallel within the main body cover 112.

[0031] Figure 4(a) is a plan view showing an example of the first tape roll 120 that constitutes the laminated tape manufacturing jig 100 shown in Figure 1.

[0032] The first tape roll 120 is constructed by winding a long tape (first tape 122) having, for example, a substantially constant width, around a cylindrical core material 124 such as a paper tube or plastic tube with an open center. The width of the first tape 122 corresponds to the length of the joint-like pattern formed, and is, for example, 2 mm to 30 mm, preferably 3 mm to 15 mm.

[0033] Herein, the term "joint-like pattern" as used herein includes patterns that mimic joints formed between two adjacent members (so-called joint patterns), patterns in which differences in height are provided along the contours of letters, figures, and other arbitrary geometric shapes to create irregularities or steps relative to a plane (so-called uneven patterns or stepped patterns), and combinations thereof.

[0034] The first tape 122 comprises a first base layer 122a and a first adhesive layer 122b.

[0035] The first base material layer 122a is composed of a thin structure such as a sheet or fabric. Preferably, the first base material layer 122a is composed of an intertwined fibrous material because it is flexible and highly elastic, and can be adhered to various coating members (e.g., calcium-based inorganic members) having uneven surfaces, corners, and curved surfaces with almost no gaps or voids.

[0036] The first base layer 122a is composed of materials such as paper (e.g., Japanese paper, creep paper), cloth (e.g., woven fabric, mesh fabric, nonwoven fabric composed of synthetic and / or natural fibers), polyester (e.g., polyester film, polyester sheet), polypropylene (e.g., polypropylene film, polypropylene sheet), polyvinyl chloride (e.g., polyvinyl chloride film, polyvinyl chloride sheet), fluororesin (e.g., polytetrafluoroethylene (PTFE) film, PTFE sheet, perfluoroalkoxyalkane (PFA) film, PFA sheet, perfluoroethylenepropene copolymer (FEP) film, FEP sheet), silicone resin (e.g., silicone film, silicone sheet), and metal foil (e.g., aluminum tape, copper foil, gold foil).

[0037] The thickness of the first substrate layer 122a is not particularly limited, and an appropriate thickness can be selected by those skilled in the art.

[0038] The first adhesive layer 122b is a layer composed of an adhesive adhesive that can adhere to the coating member, and may have either strong or weak adhesive properties to the coating member.

[0039] The adhesive that can constitute the first adhesive layer 122b is not particularly limited, but examples include synthetic adhesives, natural adhesives, and combinations thereof. Specific examples of synthetic adhesives include acrylic resin adhesives, α-olefin adhesives, urethane resin adhesives, ethylene-vinyl acetate resin adhesives, epoxy resin adhesives, vinyl chloride adhesives, vinyl acetate resin adhesives, cyanoacrylate adhesives, silicone adhesives, nitrocellulose adhesives, phenol resin adhesives, polyimide adhesives, polystyrene adhesives, polyvinyl alcohol adhesives, polyvinylpyrrolidone resin adhesives, polyvinyl butyral resin adhesives, melamine resin adhesives, urea resin adhesives, resorcinol adhesives, and rubber adhesives (e.g., chloroprene rubber adhesives, styrene-butadiene rubber adhesives, and nitrile rubber adhesives), as well as combinations thereof. Specific examples of natural adhesives include casein adhesives, rubber adhesives (e.g., natural rubber adhesives and natural rubber latex adhesives), starch adhesives, glue, and rosin, as well as combinations thereof.

[0040] The thickness of the first adhesive layer 122b is not particularly limited, and an appropriate thickness can be selected by those skilled in the art.

[0041] The first tape 122 may include other intermediate layers (not shown) between the first base layer 122a and the first adhesive layer 122b. The intermediate layer is made of a material such as paper, cloth, metal mesh, or synthetic resin, and preferably a material different from the material constituting the first base layer 122a is used.

[0042] In Figure 4(a), the first tape 122 is laminated such that the first adhesive layer 122b is located inside the first base material layer 122a (i.e., within the first tape 122, the first adhesive layer 122b is located closer to the tubular core material 124 than the first base material layer 122a).

[0043] However, in the present invention, the lamination order of the first base material layer 122a and the first adhesive layer 122b constituting the first tape 122 is not particularly limited. For example, in the first tape 122, the first base material layer may be laminated on the inside of the first adhesive layer (i.e., in the first tape 122, the first base material layer may be positioned closer to the tubular core material than the first adhesive layer) (hereinafter, a first tape having such a lamination order will be referred to as the "reverse-wound first tape").

[0044] In this invention, when using the first reverse-wound tape, it is necessary to use it in conjunction with the second reverse-wound tape described later. In that case, it should be noted that the arrangement order of the first tape 120 and the second tape 130 in Figure 1 should be reversed (i.e., the second tape 130 should be placed proximal to the tape outlet 160 in the housing 110, and the first tape 120 should be placed distal to the tape outlet 160).

[0045] Figure 4(b) is a plan view showing an example of a second tape roll 130 that constitutes the laminated tape manufacturing jig 100 shown in Figure 1.

[0046] The second tape roll 130 is constructed by winding a long tape (second tape 132) having, for example, a substantially constant width, around a cylindrical core material 134 such as a paper tube or plastic tube with an open center. The width of the second tape 132 is designed to be substantially the same as the width of the first tape 122.

[0047] The second tape 132 comprises a second base layer 132a and a second adhesive layer 132b.

[0048] The second base material layer 132a is composed of a thin structure such as a sheet or fabric. The second base material layer 132a is preferably composed of an intertwined fibrous material because it is flexible and highly elastic, and can follow the first base material layer 122a, allowing the second tape 132 and the first tape 122 to be laminated together with almost no gaps or voids forming between them.

[0049] The material constituting the second base layer 132a is the same as the material exemplified above for the first base layer 122a. In a single jig for manufacturing laminated tape, the material constituting the second base layer 132a and the material constituting the first base layer 122a may be the same or different.

[0050] The thickness of the second substrate layer 132a is not particularly limited, and an appropriate thickness can be selected by those skilled in the art.

[0051] The second adhesive layer 132b is a layer made of an adhesive that can be peeled off from the first tape roll 120 (for example, the first base material layer 122a), and is made of an adhesive that has weak tackiness to the first base material layer 122a of the first tape roll 120 (i.e., a weak tackiness adhesive layer).

[0052] The adhesive that can constitute the second adhesive layer 132b is not particularly limited, but examples include acrylic adhesives, rubber adhesives (e.g., chloroprene rubber adhesives, styrene-butadiene rubber adhesives, nitrile rubber adhesives, natural rubber adhesives, and natural rubber latex adhesives), and combinations thereof.

[0053] The thickness of the second adhesive layer 132b is not particularly limited, and an appropriate thickness can be selected by those skilled in the art.

[0054] The second tape 132 may include other intermediate layers (not shown) between the second base layer 132a and the second adhesive layer 132b. The intermediate layer is made of a material such as paper, cloth, metal mesh, or synthetic resin, and preferably a material different from the material constituting the second base layer 132a is used.

[0055] In Figure 4(b), the second tape 132 is laminated such that the second adhesive layer 132b is located inside the second base material layer 132a (i.e., within the second tape 132, the second adhesive layer 132b is located closer to the tubular core material 134 than the second base material layer 132a).

[0056] However, in the present invention, the lamination order of the second base layer 132a and the second adhesive layer 132b constituting the second tape 132 is not particularly limited. For example, in the second tape 132, the second base layer may be laminated on the inside of the second adhesive layer (i.e., in the second tape 132, the second base layer may be positioned closer to the tubular core than the second adhesive layer) (a second tape having such a lamination order is referred to as the "reverse-wound second tape").

[0057] As mentioned above, when using the reverse-wound second tape in this invention, it is necessary to use it in conjunction with the reverse-wound first tape. Furthermore, as mentioned above, care should be taken to reverse the arrangement order of the first tape 120 and the second tape 130 in Figure 1.

[0058] Furthermore, in the present invention, the first tape 122 constituting the first tape roll 120 and the second tape 132 constituting the second tape roll 130 may both be commercially available masking tapes. In particular, in the present invention, it is preferable that the second tape 132 is a masking tape because it can be easily peeled off from the first tape 122.

[0059] From a morphological standpoint, masking tapes include, for example, long, narrow tapes (e.g., masking tape), as well as those consisting of letters, symbols, other geometric shapes, and combinations thereof (e.g., masking seals and labels).

[0060] In the present invention, the masking tapes may be, for example, painting masking tapes and decorative masking tapes.

[0061] Masking tapes for painting include those used in painting and sealing work, and are also called protective tapes. Some masking tapes for painting use a base layer made of Japanese paper or synthetic resin, and an adhesive layer made of rubber-based adhesive or acrylic-based adhesive.

[0062] Decorative masking tapes include tapes, stickers, and labels printed with various patterns and colors, used for decorative purposes different from conventional masking. Some decorative masking tapes, for example, use Japanese paper (washi) for the base layer and rubber-based or acrylic-based adhesives for the adhesive layer.

[0063] Referring again to Figure 2, in the present invention, either masking tapes for painting or masking tapes for decoration can be used as the first tape 122 constituting the first tape roll 120 and the second tape 132 constituting the second tape roll 130.

[0064] For example, when using masking tape as a type of masking tape, in this invention, decorative masking tape may be used as the first tape 122, and painting masking tape may be placed on top of it as the second tape 132.

[0065] In the laminated tape manufacturing jig 100 of the present invention shown in Figure 2, a case in which two tape rolls (i.e., a first tape roll 120 and a second tape roll 130) are arranged inside the housing 110 has been described, but the number of tape rolls that can be used in the present invention is not limited to this.

[0066] For example, a third tape roll (not shown) may be arranged in parallel within the housing 110 along with the first tape roll and the second tape roll. In that case, the third tape (not shown) constituting the third tape roll will be stacked within the housing together with the first tape constituting the first tape roll and the second tape constituting the second tape roll, and can be discharged outside the housing as a triple-layered tape.

[0067] (First support and second support) As shown in Figure 2, in the laminated tape manufacturing jig 100 of the present invention, the first support column 140 and the second support column 150 are arranged in parallel within the main body cover 112.

[0068] The first support column 140 and the second support column 150 each have a cylindrical appearance that protrudes inward from the main body cover 112, and are fixed to the inside of the main body cover 112 or are arranged so that they can rotate within the main body cover 112 using means known to those skilled in the art (e.g., bearings).

[0069] When the first support column 140 is fixed inside the main body cover 112, the outer diameter of the first support column 140 is designed to be smaller than the diameter of the opening of the cylindrical core material 124 that constitutes the first tape roll 120. As a result, when the first tape roll 120 is positioned on the first support column 140 and the first tape 122 is pulled out from the first tape roll 120, the first tape roll 120 can rotate around the first support column 140 in accordance with this pulling out.

[0070] Similarly, when the second support column 150 is fixed inside the main body cover 112, the outer diameter of the second support column 150 is designed to be smaller than the diameter of the opening of the cylindrical core material 134 that constitutes the second tape roll 130. This allows the second tape roll 130 to rotate around the second support column 150 in accordance with the second tape roll 130 when the second tape 132 is pulled out from the second tape roll 130 while the second tape roll 130 is positioned on the second support column 150.

[0071] Alternatively, if the first support column 140 is positioned to be rotatable within the main body cover 112, the outer diameter of the first support column 140 is designed to be approximately the same as the diameter of the opening of the cylindrical core material 124 that constitutes the first tape roll 120. As a result, when the first tape roll 120 is positioned on the first support column 140 and the first tape 122 is pulled out from the first tape roll 120, the first tape roll 120 can rotate together with the first support column 140 in accordance with this pulling out.

[0072] Similarly, when the second support column 150 is positioned to be rotatable within the main body cover 112, the outer diameter of the second support column 150 is designed to be approximately the same as the diameter of the opening of the cylindrical core material 134 that constitutes the second tape roll 130. As a result, when the second tape roll 132 is pulled out from the second tape roll 130 while the second tape roll 130 is positioned on the second support column 150, the second tape roll 130 can rotate together with the second support column 150 in accordance with this pull-out.

[0073] In this way, the first support column 140 and the second support column 150, through the main body cover 112, allow the first tape roll 120 and the second tape roll 130 to rotate independently within the housing 110, with the first support column 140 and the second support column 150 as their respective axis centers, corresponding to the pulling out of the first tape 122 and the second tape 132, respectively.

[0074] The heights of the first support column 140 and the second support column 150 are not particularly limited and can be any height that can be accommodated within the housing 110.

[0075] (Method of manufacturing laminated tape) In Figure 1, in the laminated tape manufacturing jig 100 of the present invention, the first tape 122 constituting the first tape roll 120 and the second tape 132 constituting the second tape roll 130 are pulled out together from the tape pull-out opening 160 of the housing 110. As a result of this pulling out, the first tape roll 120 and the second tape roll 130 rotate within the housing 110 about the first support column 140 and the second support column 150 as their axes. Then, new first tapes 122 and second tapes 132 are pulled out from the first tape roll 120 and the second tape roll 130, respectively, within the housing 110.

[0076] In the housing 110, the second tape 132 pulled from the second tape roll 130 comes into contact with the first tape 122 pulled from the first tape roll 120 when it comes into contact with, for example, the shoulder portion 166 of the lamination guide 116, and the first tape 122 and the second tape 132 are adhered to each other to form a laminated tape 170. After that, the required length of the laminated tape 170 is pulled out from the tape outlet 160 of the housing 110.

[0077] The resulting laminated tape 170 can be used, for example, as a laminate for forming joint patterns on a member such as a coated member.

[0078] (Method for manufacturing a coated member having a joint-like pattern) Next, an example of a method for producing a coated member having a joint-like pattern using a laminated tape obtained from the laminated tape manufacturing jig of the present invention will be described with reference to the drawings. In the following description, the case in which the laminated tape 170 shown in Figure 1 is used as a laminate for forming a joint-like pattern will be explained with reference to Figures 5 and 6.

[0079] In the present invention, first, as shown in Figure 5(a), the laminated tape 170 is placed on the coating member 210.

[0080] A coating component is a component on which the formation of a joint-like pattern is desired, and may be any of the following three-dimensional shapes: plate-like, columnar, disc-like, or other. Examples of coating components include: calcium-based inorganic components such as concrete, cement, gypsum, stone, and artificial slate (sometimes simply called slate); tiles, blocks, gypsum or wood-based boards, flooring (including, for example, wood, stone, or synthetic resin); glass plates, synthetic resin plates (including, for example, polyethylene, polypropylene, polyvinyl chloride, polystyrene, and ABS (acrytonitrile butadiene styrene) resin); wooden or metal columns, gates, exterior wall materials, interior wall materials, and other building exterior and interior materials; exterior and interior materials for vehicles such as automobiles, trains, ships, and aircraft; casings for household electrical appliances such as refrigerators, washing machines, televisions, and microwave ovens; playground equipment such as slides and jungle gyms; toys such as toy cars and miniature house toys (e.g., dollhouses); and so on. The coating material may have a primer such as a sealer or filler, a rust inhibitor, or other undercoat paint known to those skilled in the art applied to it beforehand.

[0081] The laminated tape 170 is placed on the coating member 210 by bonding the first adhesive layer of the first tape constituting the laminated tape 170 to the coating member 210. In this case, the laminated tape 170 may be used after being drawn out to a predetermined length from the laminated tape manufacturing jig of the present invention and cut in advance, or the laminated tape 170 may be drawn out from the laminated tape manufacturing jig of the present invention and bonded to the coating member 210, and then the laminated tape 170 may be cut from the laminated tape manufacturing jig. For example, if the coating member 210 is a flat tile, the laminated tape 170 is placed so as to protrude from the plane 212 of the coating member 210 (Figure 6(a)).

[0082] Next, as shown in Figure 5(b), a coating film 220 is formed on the side of the coating member 210 where the laminated tape 170 is positioned.

[0083] The coating film 220 may be provided at approximately the same height as the laminated tape 170 placed on the coating member 210, for example (Figure 6(b)), but the arrangement of the coating film in the present invention is not limited thereto. For example, the surface of the coating film may be lower than the surface of the laminate, or the surface of the coating film may be higher than the surface of the laminate (for example, covering the laminate).

[0084] The type of paint that can form such a coating film 220 is not particularly limited, but it is preferable that the paint be able to form a thick coating or a moderate film thickness. Examples of paints that can form such a thick coating or a moderate film thickness include acrylic paints, styrene-acrylic paints, urethane paints, epoxy paints, and hobby paints (e.g., lacquers and enamel paints), as well as combinations thereof. For example, a surface modification composition such as the one described in Patent Document 1 may be used as the paint.

[0085] Subsequently, as shown in Figure 5(c), the second tape 132 of the laminated tape 170 is separated from the coating film 220.

[0086] Specifically, after the coating film 220 is formed, the second tape 132 is slowly peeled off while the first tape 122 of the laminated tape 170 is placed on the coating member 210.

[0087] For example, if the coating film 220 is formed to be approximately the same height as the uppermost surface of the second tape 132 of the laminated tape 170, as shown in Figure 6(b), the peeling off of the second tape 132 will result in a height difference between the uppermost surface of the first tape 122 remaining on the coating member 210 and the uppermost surface of the coating film 220, corresponding to the thickness of the peeled-off second tape 132 (Figure 6(c)). In addition, the first base material layer 122a constituting the first tape 122 will be exposed on the uppermost surface of the first tape 122.

[0088] As a result, a coating film 220 and joints 224 with a depth equivalent to the thickness of the peeled second tape 132 are formed on the surface of the coating member 210 (Figure 6(c)), and these joints 224 appear as a pattern (joint-like pattern) on the surface of the coating member 210 as shown in Figure 5(d).

[0089] On the other hand, when the coating is formed covering the laminated tape 170, the peeling of the second tape 132 results in a height difference between the remaining coating surface and the constituent surface of the first tape 122 that is exposed by the peeling of the second tape 132, which is equal to or greater than the thickness of the second tape 132. In this way, the height difference between the remaining coating surface and the constituent surface of the first tape 122 can be varied depending on how the coating is formed on the laminated tape 170.

[0090] Subsequently, the coating film 220 and the joints 224 may be coated with a clear coating known to those skilled in the art as needed to provide the desired gloss and for surface protection, and a clear coat layer 230 may be applied (Figure 6(d)).

[0091] In this way, a coated member 200 having a joint-like pattern can be manufactured.

[0092] Multiple coated members 200 having a joint-like pattern, as described above, are arranged using the joints 224 that appear on their surface, for example, as shown in Figure 7.

[0093] The above method allows for the easy formation of joint-like patterns on the paint film without the need for special work and / or materials for joint formation, such as cutting grooves or using caulking material.

[0094] Although Figures 5 and 6 above illustrate the case in which a tape-shaped laminate is used as the laminate for forming a joint-like pattern, the present invention is not limited to this embodiment. For example, if, instead of a tape-shaped laminate for forming a joint-like pattern, a laminate of elongated masking seals or labels having letters, symbols, or other arbitrary geometric shapes is used as the first tape and second tape, a joint-like pattern (so-called uneven pattern or stepped pattern) corresponding to the shape (e.g., contour) of the masking seal or label can be easily created on the coated member. Furthermore, if a decorative masking seal or label is used as the first base material layer of the first tape, the colors, figures, and patterns applied to the decorative masking seal or label of the first base material layer can appear on the surface as part of the joint-like pattern.

[0095] (2) Other jigs for making laminated tapes Figure 8 is an exploded perspective view of another example of the jig for manufacturing laminated tapes according to the present invention.

[0096] The laminated tape manufacturing jig 300 shown in Figure 8 houses three first tape rolls 320A, 320B, and 320C and a wide second tape roll 330 between the main body cover 112 and the lid cover 114 that constitute the housing 110, so that they can rotate around the first support column 340 and the second support column 350, respectively.

[0097] The first tape rolls 320A, 320B, and 320C are each made of the same material as the first tape roll 120 shown in Figure 1, and their widths may be the same or different from each other. The second tape roll 330 is made of the same material as the second tape roll 130 shown in Figure 1.

[0098] In the laminated tape manufacturing jig 300 shown in Figure 8, the sum of the widths of the first tapes 320A, 320B, and 320C that make up the three first tape rolls 320A, 320B, and 320C is designed to be approximately the same as the width of the second tape 332 that makes up the second tape roll 330. Furthermore, each of the first tapes 322A, 322B, and 322C independently displays arbitrary colors, patterns, figures, etc.

[0099] In this configuration, the laminated tape (not shown) pulled out from the tape outlet 160 of the laminated tape manufacturing jig 300 has a second tape 332 positioned above it, which is attached to the three first tapes 322A, 322B, and 322C positioned below it, with each tape arranged in parallel. Therefore, by attaching the resulting laminated tape to the coating member 210, for example, and slowly peeling off only the second tape 332, a joint-like pattern can be formed on the coating member 210, consisting of the three first tapes 322A, 322B, and 322C arranged in parallel (see joint-like pattern 380 in Figure 10).

[0100] The embodiment shown in Figure 8 describes the case in which three first tape rolls 320A, 320B, and 320C are used, but the present invention is not particularly limited thereto. When multiple first tape rolls are used in stacks, preferably two to seven, and more preferably two to four, tape rolls can be used in stacks.

[0101] Figure 9 is an exploded perspective view of yet another example of the jig for manufacturing laminated tapes according to the present invention.

[0102] The laminated tape manufacturing jig 400 shown in Figure 9 houses three first tape rolls 420A, 420B, and 420C and a wide second tape roll 430 between the main body cover 112 and the lid cover 114 of the housing 110, so that they can rotate around the first support column 440 and the second support column 450, respectively. An annular spacer 460 is placed between the first tape rolls 420A and 420B, and an annular spacer 470 is placed between the first tape rolls 420B and 420C.

[0103] The annular spacers 460 and 470 have a circular hole in the center that is larger than the diameter of the first support column 440, and the thickness of the annular spacer 460 and the annular spacer 470 may be the same or different. The annular spacers 460 and 470 are each independently made of the aforementioned materials such as plastic, metal, or composite material.

[0104] The annular spacers 460 and 470 are used to provide gaps between the first tapes 422A and 422B, and between the first tapes 422B and 422C, in the first tape rolls 420A, 420B, and 420C, corresponding to the respective thicknesses of the spacers 460 and 470.

[0105] On the other hand, the first tape rolls 420A, 420B, and 420C are each made of the same material as the first tape roll 120 shown in Figure 1, and their widths may be the same or different from each other. The second tape roll 430 is made of the same material as the second tape roll 130 shown in Figure 1.

[0106] In the laminated tape manufacturing jig 400 shown in Figure 9, the sum of the widths of the first tapes 422A, 422B, and 422C that make up the three first tape rolls 420A, 420B, and 420C, and the widths of the annular spacers 460 and 470, is designed to be approximately the same as the width of the second tape 432 that makes up the second tape roll 430. Furthermore, each of the first tapes 422A, 422B, and 422C independently displays arbitrary colors, patterns, figures, etc.

[0107] In this configuration, the laminated tape (not shown) pulled out from the tape outlet 160 of the laminated tape manufacturing jig 400 has a second tape 432 positioned above it, which is attached to the three first tapes 422A, 422B, and 422C positioned below it, with a gap corresponding to the thickness of the annular spacers 460 and 470. Therefore, by attaching the resulting laminated tape to the coating member 210, for example, and slowly peeling off only the second tape 432, a joint-like pattern can be formed on the coating member 210, consisting of the three first tapes 320A, 320B, and 320C arranged parallel to each other with gaps of 452 and 454 (see joint-like pattern 480 in Figure 10).

[0108] In the embodiment shown in Figure 9, a case using three first tape rolls 420A, 420B, and 420C and two annular spacers 460 and 470 has been described, but the present invention is not particularly limited thereto. When multiple first tape rolls are used in stacks, preferably two to seven, more preferably two to four tape rolls can be used in stacks. Correspondingly, preferably one to six, more preferably one to three annular spacers can be used sandwiched between the first tape rolls. [Industrial applicability]

[0109] According to the present invention, for example, when forming a coating film on various coating materials, it is possible to form joint-like patterns of a desired shape. Alternatively, without forming such a coating film, the laminated tape can be directly attached to a predetermined substrate surface, allowing it to be used for decoration on vehicles such as automobiles, motorcycles, railway trains, and ships, as well as on the interior walls of houses. Thus, the present invention is useful in technical fields such as architecture, automotive, and electrical engineering. [Explanation of Symbols]
