Description

Technical Field

[0001] The present invention relates to a method for providing wallpaper and a wallpaper roll.

Background Art

[0002] Conventionally, as a method for installing wallpaper on an indoor wall surface or the like, a method of overlapping and pasting has been known. In this method of overlapping and pasting, a sheet for wallpaper having ears is used. After positioning the ears of two sheets overlapping each other by several centimeters, the overlapping portion of both sheets is cut with a cutting tool such as a cutter, and after removing the unnecessary portions of both sheets, it is pasted onto a wall surface or the like with a joint roller or the like (see, for example, Patent Document 1).

[0003] In addition, a butting method is also known in which a sheet for wallpaper having no ears, that is, a sheet having the same width as the wallpaper after pasting, is used, and the edges of the sheet that is newly pasted and the already pasted wallpaper are butted against each other without overlapping the sheets. For example, in a pattern design wallpaper having a plain finish (plain, textured, cloth-like, stripe, geometric design, etc.), the butting construction is also often used.

[0004] In the butting construction, immediately before applying the adhesive during construction, the sheet for wallpaper is slit to approximately the effective width on the pasting machine, and both ends of the slit are discarded on the spot.

[0005] On the other hand, in the case of wallpaper having various pattern designs, the sheet for this wallpaper requires a pattern matching mark for pasting so that the pattern designs are continuous between adjacent wallpapers, and this pattern matching mark needs to be provided in the portion to be discarded outside the effective width. Therefore, this sheet for wallpaper is designed to be wider by 10 mm or more on one side than the effective width. This pattern matching mark is only necessary during pattern matching and is unnecessary after pasting, so it is provided in the portion to be discarded outside the effective width.

[0006] Thus, since wallpapers with patterned designs and plain wallpapers coexist, for the purpose of commonizing the manufacturing process and the like, although they will be discarded during construction, blank portions are also provided at both ends of the plain wallpapers. Sometimes, even plain wallpapers may require a slight blank margin during production. However, even in such cases, when performing butting construction, the ends that are outside the effective width will be discarded.

Summary of the Invention

Problems to be Solved by the Invention

[0008] Currently, the ends of wallpaper sheets that are outside the effective width and are discarded during construction are mixed with other waste as end waste, and construction contractors take them back and dispose of them as industrial waste. Since construction contractors do not understand the materials of the end waste outside the effective width, or cannot determine whether it is PVC or other plastics, or it is an integral part with paper and cannot be separated, it is impossible for construction contractors to separate the end waste. As a result, it is being discarded as industrial waste.

[0009] Therefore, there has been a demand for wallpapers that can reduce the amount of waste generated during the process from manufacturing to construction and can further reuse the waste. The present invention has been made by paying attention to the above points, and aims to provide a method for providing a wallpaper and a wallpaper roll that can reduce the amount of waste generated during the process from manufacturing to construction and can easily reuse the waste.

Means for Solving the Problems

[0010] According to one aspect of the present invention, there is provided a method for providing a plain wallpaper having a constant width dimension, comprising: a step of generating a plain wallpaper base roll in a roll form; a step of cutting off at least one end side in the width direction of the wallpaper base roll to generate a wallpaper roll having a constant width dimension, wherein one end side is an area where construction can be carried out up to its end and has a width equal to or greater than the width dimension of the wallpaper; and a step of shipping the wallpaper roll. In the step of generating the wallpaper base roll, a wallpaper base roll having a pattern design without marks for pattern matching is generated. A method for providing a wallpaper is provided.

[0011] Here, the mark for pattern matching refers to a mark for positioning in the longitudinal direction of the wallpaper for bonding adjacent wallpapers so that the pattern designs are continuous.

[0012] Further, according to another aspect of the present invention, there is provided a wallpaper roll in a roll form for cutting out a wallpaper having a constant width dimension, which has a constant width dimension and a width equal to or greater than the width of the wallpaper, at least one end side in the width direction is an area where construction can be carried out up to its end, and has a pattern design without marks for pattern matching. A wallpaper roll is provided.

Advantages of the Invention

Best Mode for Carrying Out the Invention

[0015] Next, an embodiment of the present invention will be described below with reference to the drawings. Here, the drawings are schematic, and the relationship between the thickness and the planar dimensions, the ratio of the thickness of each layer, etc. are different from the actual ones. Further, the embodiments shown below are examples of the configurations for embodying the technical idea of the present invention, and the technical idea of the present invention is not limited to the materials, shapes, structures, etc. of the components being the following. The technical idea of the present invention can be variously modified within the technical scope defined by the claims described in the claims.

[0016] Also, in the embodiments shown below, the wallpaper base roll, the wallpaper roll, the sheet, and the wallpaper are defined as follows, respectively. The wallpaper base roll means a roll in which a sheet that will later become wallpaper is wound in a fabric-like state, as shown in FIG. 3(a) described later, and the sheet having ears provided at both ends in the width direction for use in gripping the strip-like sheet from both ends in the manufacturing process is wound.

[0017] The wallpaper roll means a roll in which, in the wallpaper base roll, as shown in FIG. 3(b) described later, the sheet in a state where the portions on both ends of the slit line 3 provided at both ends in the width direction are cut off is wound in a fabric-like state and has a width of the effective width L1, or a roll in which, in the wallpaper base roll, the sheet in a state where only the end portion side of the slit line 3 is cut off at only one of the slit lines 3 provided at both ends in the width direction is wound in a fabric-like state and is a roll in which a sheet having ears only at one end in the width direction is wound.

[0018] A single-sheet paper refers to a sheet obtained by cutting the length of the sheet in a wallpaper roll to match the length of the object to be constructed. When the wallpaper roll has a width of the effective width L1 without ear portions as shown in Fig. 3(b), the single-sheet paper obtained from this wallpaper roll is a sheet having an effective width L1 without ear portions. When the wallpaper roll has ear portions only at one end as shown in Fig. 5, the single-sheet paper obtained from this wallpaper roll is a sheet having ear portions only at one end and being wider than the effective width L1 by the amount of the ear portions.

[0019] Wallpaper refers to a sheet after being pasted onto the object to be constructed, as shown in Fig. 4, which has no ear portions and has a width of the effective width L1.

[0020] <Configuration of Wallpaper> Fig. 1 is a plan view schematically showing the configuration of wallpaper 1. Wallpaper 1 has a constant dimension in the width direction and is an area where construction can be carried out up to the regions at both ends in the width direction. The effective width L1 is set to 920 mm, for example, in accordance with the effective width of the wallpaper specified in JIS A 6921. The length of wallpaper 1 in the longitudinal direction is equal to the length of the object to be constructed. Wallpaper 1 is formed, for example, by laminating a base material, a foamed resin layer, a plain-printing layer, and a surface protection layer in this order. Note that the configuration of wallpaper 1 is not limited to this and can be formed using other materials.

[0021] <Method of Providing Wallpaper> Next, the method of providing wallpaper 1 will be described with reference to Figs. 2 to 4. (Manufacturing Process) First, a sheet-like base material having a width of about 930 mm (hereinafter referred to as the base material width L2) is prepared, taking into account the effective width L1 (920 mm) of wallpaper 1 and the allowance α. A layer of a foaming agent-containing composition that becomes a foamed resin layer is formed on one surface of the base material to make it in a sheet state.

[0022] Next, on the surface of the layer of the foaming agent-containing composition opposite to the base material, for example, a single color is printed using a printing method to form a plain printing layer. The printing layer is printed so as to be located at the center in the width direction of the base material, and is printed over the entire printing width L3 corresponding to the sum of the effective width L1 and the margin. Next, on the printing layer, for example, an acrylic resin, a polyvinyl chloride resin, etc. are applied to form a surface protection layer.

[0023] Subsequently, on the surface protection layer, slit line 3 is printed using a printing method. Slit line 3 may be printed using, for example, water-soluble ink. Slit line 3 is a line segment indicating the cutting position when cutting out a sheet of the effective width L1 from a sheet-like workpiece formed by laminating the above-mentioned layers on a base material having a base material width L2, and is printed at positions shifted 460 mm to the left and right in the width direction starting from the center in the width direction of the base material.

[0024] Subsequently, by heating, the layer of the foaming agent-containing composition is foamed to form a foamed resin layer, and then, if necessary, embossing is performed from the surface protection layer side using an embossing roll to form an embossed pattern. In this way, by winding up the sheet formed by laminating the above-mentioned layers on one surface of the base material in a sheet-like manner, the wallpaper original roll 10 having a constant width dimension in the width direction shown in Fig. 3(a) is formed. At this point, the wallpaper original roll 10 is in a state formed on a base material having a base material width L2, and the width of the wallpaper original roll 10 is wider than the effective width L1.

[0025] Note that the wallpaper original roll 10 does not have a pattern matching mark (mark for pattern matching) for joining the patterns so that the pattern designs are continuous between adjacent wallpapers. The wallpaper original roll 10 has a pattern design that does not include a pattern matching mark.

[0026] Subsequently, the wallpaper base roll 10 having a base material width L2 is cut along its slit line 3, and the members on the end side of the slit line 3 are cut off at both ends respectively. As a result, a plain sheet having an effective width L1 can be obtained as a wallpaper roll 20 shown in Fig. 3(b) wound in a stock form. After cutting off the both end side portions of the wallpaper base roll 10 from the slit line 3, if the slit line 3 remains at this time, the remaining slit line 3 may be erased by wetting it with water and rubbing it with a sponge or the like that has been moderately wrung out.

[0027] Here, the printing width L3 is larger than the effective width L1. Therefore, the wallpaper roll 20 cut out from the wallpaper base roll 10 has a foamed resin layer, a printing layer, and a surface protection layer formed on the entire surface up to both ends in the width direction, and is a plain wallpaper roll 20 having a constant width dimension in the width direction and an effective width L1 that can be applied up to both ends in the width direction. Here, although the slit line 3 is printed on the surface protection layer, when there is no surface protection layer, the slit line 3 may be formed on the printing layer that becomes the outermost layer.

[0028] The stock-form wallpaper roll 20 with an effective width L1, with the end sides cut off at the positions of each slit line 3, is shipped as a product. Note that the length of the wallpaper base roll 10 remains as it is, and a sheet with both ends or one end side in the width direction cut off at the position of its slit line 3 may be used as the wallpaper roll 20, or a sheet with its length cut to a certain length and wound up may also be used as the wallpaper roll 20.

[0029] (Sorting process) In the sorting process, the portions on both end sides of the sheet of the wallpaper base roll 10 cut off at the slit line 3 (hereinafter also referred to as ears) are collected and sorted. The ear portions on both ends of the sheet cut off by the slit line 3 are composed of a laminate in which a foamed resin layer, a plain printed layer, and a surface protection layer are laminated in this order on a base material. The manufacturer of this wallpaper base roll 10 recognizes what these base materials and the materials constituting each layer are. Therefore, they can be separated considering the types of materials. After subjecting these separated materials to a predetermined treatment, they can be reused. For example, they can be utilized as cat toilet sand.

[0030] <Construction method> When applying Wallpaper 1 to the object to be constructed, as shown in Fig. 3(c), the constructor cuts the sheet of the wallpaper roll 20 according to the length of the object to be constructed to obtain a plurality of single sheets 21. Here, the width of the wallpaper roll 20 is the effective width L1 (Fig. 3(b)). Therefore, the sheet of the wallpaper roll 20 may be cut so that the length in the longitudinal direction becomes the height according to the object to be constructed.

[0031] Next, the first single sheet 21a is attached to the object to be constructed. Next, the second single sheet 21b is placed, for example, on the right side of the single sheet 21a, and the single sheet 21b is attached so that the right side of the single sheet 21a and the left side of the single sheet 21b abut (Fig. 4). Thereafter, the single sheets 21 are sequentially pasted together in the same procedure. As a result, a state is obtained in which a plurality of single sheets 21 (three sheets in Fig. 4) are applied to the object to be constructed, that is, a state in which the wallpaper 1 (1a to 1c) having the effective width L1 is attached to the object to be constructed.

[0032] Here, the single sheets 21 cut out from the wallpaper roll 20 do not have ear portions at either end in the width direction. Therefore, after attaching the single sheets 21 to the object to be constructed, the step of removing the ear portions is unnecessary.

[0033] Also, since the wallpaper 1 is plain, there is no need to consider the pattern matching between the wallpapers 1a to 1c (single sheets 21). Therefore, even if the single sheets 21 do not have pattern matching marks, they can be easily attached.

[0034] <Effect> (1) The width of the shipped wallpaper roll 20 is the effective width L1 and it has no ear parts. Therefore, the constructor can cut the longitudinal direction of the wallpaper roll 20 to a predetermined length to obtain the single-sheet paper 21 and paste this on the object to be constructed, without the need to perform processes such as cutting the ear parts.

[0035] Also, since it is a plain single-sheet paper (wallpaper), even without a pattern matching mark, the single-sheet paper 21 can be easily pasted by simply butting and pasting the ends of the single-sheet paper 21 together.

[0036] Also, when the constructor obtains the single-sheet paper 21 and after pasting the single-sheet paper 21 on the object to be constructed, there is no need to cut off the ear parts. Therefore, there is no need to use the cut tape used for overlapping pasting, and also, the usage fee of the construction glue can be reduced because there are no ear parts. Also, unnecessary materials generated during construction, such as a part of the sheet cut off at the position of the slit line 3 that was finally discarded, can be reduced, and the waste generated during construction can be reduced.

[0037] (2) The wallpaper 1 (single-sheet paper 21) has a plain pattern design such as white, solid color, plain, sand texture, cloth texture, ground pattern, fabric texture, painted texture, stripe, and geometric design. Therefore, there is no need to perform pattern matching using a pattern matching mark. Therefore, unnecessary pattern matching marks are not provided, and material reduction and simplification of the manufacturing process can be achieved.

[0038] (3) Since the single-sheet paper 21 has no ear parts, the margin in the width direction of the base material and each layer when generating the wallpaper master roll 10 may be the minimum width required in the process of generating the wallpaper master roll 10 to obtain the wallpaper 1 with the effective width L1. Therefore, compared with the case of providing ear parts for the purpose of providing a pattern matching mark, etc., the width of the ear parts required in the manufacturing process can be reduced, and accordingly, various materials required during manufacturing can be reduced. As a result, the labor and energy required for production can be reduced.

[0039] In addition, since there is no ear part, the wallpaper roll 20 can be made lighter and smaller, the transportation efficiency can be improved, and it is also beneficial from the perspective of environmental consideration.

[0040] (4) After cutting out the wallpaper roll 20 from the wallpaper stock roll 10, since the wallpaper roll 20 without this ear part is shipped, the portions corresponding to the ear parts of the wallpaper stock roll 10, that is, both end portions of the sheet cut off at the position of the slit line 3, remain on the manufacturer side.

[0041] Since the manufacturer recognizes the material of the sheet, the ear parts can be separated and reused. If the ear parts were to be cut off by the constructor, the constructor side may not understand the material of the ear parts, may not be able to determine whether they are PVC or other plastics, or may not be able to separate them from the integrated object with paper, so they cannot be separated and have to be discarded as waste.

[0042] In the case of the wallpaper roll 20 according to this embodiment, the manufacturer recognizes the material of the ear parts and can accurately separate them. Therefore, the ear parts that were conventionally discarded can be separated and reused, and wallpapers that consider the current environment can be obtained.

[0043] Incidentally, in the case of wallpaper with ear parts, assuming that the effective width L1 shown in FIG. 2 is 920 mm, the printing width L3 is 920 mm or more, and the base material width L2 needs to be about 960 mm to 980 mm. As a result, the width of the ear parts finally discarded is about 40 mm to 60 mm in total for the left and right ends, and about 5% of the portion in the width direction was discarded. According to the method for providing wallpaper according to this embodiment, the width of the discarded ear parts can be made smaller.

[0044] <Modification Example> (1) The width of the wallpaper 1 does not necessarily have to be 920 mm conforming to JIS A 6921, and it can also be applied when manufacturing wallpaper 1 with an arbitrary width such as 300 mm, 600 mm, 1000 mm, etc. (2) The wallpaper roll 20 does not have ears. Therefore, in order to protect both ends of the wallpaper roll 20 wound in a roll shape from being damaged, it may be packed in a state where cardboard or the like is placed at both ends of the wallpaper roll 20 as ear pads during packing. (3) In this embodiment, the case where neither the left nor the right end of the wallpaper roll 20 has ears has been described. However, as shown in FIG. 5, a configuration in which either one of the left and right ends has an ear and the other does not have an ear may also be used.

[0045] In this case, the sheet paper 21 obtained by cutting the wallpaper roll 20 has an ear on one end side in the width direction. Therefore, before attaching the sheet paper 21 to the object to be constructed, a step of cutting off the ear or attaching the sheet paper 21 to the object to be constructed, and after overlapping and attaching the sheet papers 21, a step of cutting off the ear on one end side is required.

[0046] In this case, since one end of the wallpaper roll 20 does not have an ear, compared with the case where both ends have ears, material reduction and energy loss reduction can be achieved, transportation efficiency can be improved, and the amount of waste generated during construction can be reduced. In addition, since one end is an ear, when the wallpaper roll 20 is leaned and placed, by leaning it so that the side with the ear is down, it is possible to suppress deformation or damage of the constructible part.
