Wallpaper roll

Abstract

To provide a wallpaper roll that reduces an amount of waste generated during processes from manufacture to installation and enables waste to be reused.SOLUTION: A wallpaper raw material roll 10 in a plain tone and in the form of a cloth roll is produced, and at least one widthwise end of the wallpaper raw material roll 10 is cut off to produce a wallpaper roll 20 having a constant width dimension, the wallpaper roll 20 having a workable area up to at least one end and having a width equal to or greater than a widthwise dimension of wallpaper 1, and the wallpaper roll 20 is shipped. The wallpaper raw material roll 10 is produced so as to have a pattern design that does not include any mark for pattern matching. During application, a step of cutting off a lug portion at least at one end side of the wallpaper roll 20 is not required, and accordingly, the application step can be simplified. In addition, since a manufacturer cuts off the lug portion at least at one end side and is aware of a material of the lug portion, the lug portion can be easily separated and reused.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention relates to a wallpaper roll. [Background technology]

[0002] Conventionally, the overlapping application method has been known as a method for applying wallpaper to indoor walls, etc. This overlapping application method involves using wallpaper sheets with edges, positioning the edges of two sheets by overlapping them by several centimeters, cutting the overlapping portion of both sheets with a cutter or other blade, removing unnecessary portions of both sheets, and then attaching them to the wall, etc. with a joint roller or the like (see, for example, Patent Document 1).

[0003] Also known is a method of butting wallpaper sheets that do not have edges, that is, sheets of the same width as the wallpaper after application, in which the sheets are not overlapped and the edges of the already applied wallpaper and the newly applied sheet are butted together. For example, butt-fitting construction is often used for plain-colored wallpapers (plain, sand-grained, cloth-grained, striped, geometric designs, etc.).

[0004] In butt joint construction, the wallpaper sheet is slit to approximately the effective width on the pasting machine just before applying the paste during construction, and both ends of the slit are discarded on the spot.

[0005] On the other hand, in the case of wallpaper with various pattern designs, the wallpaper sheet needs a pattern matching mark to be attached so that the pattern designs of adjacent wallpapers are continuous, and this pattern matching mark needs to be provided on the discarded part outside the effective width. For this reason, the wallpaper sheet is designed to be at least 10 mm wider on each side than the effective width. This pattern matching mark is only necessary when matching patterns, and is unnecessary after pasting, so it is provided on the discarded part outside the effective width.

[0006] In this way, wallpaper with a pattern design and plain wallpaper coexist, and in order to standardize the manufacturing process, etc., blank areas are provided at both ends of the plain wallpaper, even though these will be discarded during installation. Sometimes, even plain wallpaper requires a small amount of margin during production, but even in this case, the edges outside the effective width will be discarded when the wallpaper is butted together.

[0007] [Patent Document 1] Japanese Utility Model Application Publication No. 2-106500 Summary of the Invention [Problem to be solved by the invention]

[0008] Currently, the ends of wallpaper sheets that fall outside the effective width and are discarded during construction are mixed with other waste as end waste and are taken home and disposed of as industrial waste by construction companies. Since construction companies do not understand the material of the end waste that falls outside the effective width, cannot determine whether it is PVC or other plastics, or it is combined with paper and cannot be separated, it is impossible for construction companies to separate the end waste, and as a result, it is discarded as industrial waste.

[0009] Therefore, there has been a demand for wallpaper that can reduce the amount of waste generated from the manufacturing to installation process and that can also reuse waste. The present invention has been made in light of the above-mentioned points, and has an object to provide a wallpaper roll which reduces the amount of waste generated in the process from production to installation and makes it easy to reuse the waste. [Means for solving the problem]

[0010] According to one aspect of the present invention, there is provided a method for providing plain wallpaper with a constant width dimension, the method comprising the steps of: generating a plain wallpaper base roll in the form of a bolt; cutting off at least one widthwise end of the wallpaper base roll to generate wallpaper rolls with a constant width dimension having a width equal to or greater than the width dimension of the wallpaper in an area that can be worked on up to that end; and shipping the wallpaper rolls, wherein the step of generating the wallpaper base rolls produces wallpaper base rolls with a picture design that does not include marks for pattern matching.

[0011] The pattern matching marks referred to here are marks for determining the position of the wallpaper in the longitudinal direction so that adjacent wallpapers are pasted together so that the pattern designs are continuous.

[0012] According to another aspect of the present invention, there is provided a wallpaper roll in the form of a bolt of cloth from which wallpaper of a constant width dimension is cut, the wallpaper roll having a constant width dimension and a width greater than or equal to the width of the wallpaper, at least one end of the width direction being an area that can be worked up to that end, and having a pattern design that does not include marks for pattern matching. Effect of the Invention

[0013] According to one aspect of the present invention, it is possible to obtain a wallpaper roll that can reduce the amount of waste generated during the process from production to installation and that allows the waste to be reused. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[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 thickness and planar dimensions, the thickness ratio of each layer, etc. differ from the actual ones. Furthermore, the embodiments shown below are examples of 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 described below. The technical idea of ​​the present invention can be modified in various ways within the technical scope defined by the claims.

[0016] In the embodiment described below, the wallpaper roll, wallpaper roll, paper sheets, and wallpaper are defined as follows. A wallpaper raw roll is a roll in which the sheet that will later become wallpaper has been wound into a roll of cloth, as shown in Figure 3(a) described below, and in which the sheet has been wound up with lugs on both ends in the width direction, which are used to hold the strip-shaped sheet from both ends during the manufacturing process.

[0017] A wallpaper roll refers to a roll of wallpaper material having an effective width L1, formed by cutting off both ends of a wallpaper base roll at slit lines 3 at both ends in the width direction, and winding up the sheet into a roll of cloth, as shown in Figure 3(b) described below; or a roll of wallpaper material having a sheet with a lug only at one end in the width direction, formed by cutting off only one end of a wallpaper base roll at one of the slit lines 3 at both ends in the width direction, and winding up the sheet into a roll of cloth.

[0018] A sheet is a wallpaper roll that has been cut to match the length of the object to be treated. When a wallpaper roll has an effective width L1 with no selvage as shown in Figure 3(b), the sheets obtained from this wallpaper roll have an effective width L1 with no selvage. When a wallpaper roll has selvage only at one end as shown in Figure 5, the sheets obtained from this wallpaper roll have selvage only at one end and are wider than the effective width L1 by the amount of the selvage.

[0019] Wallpaper refers to a sheet after it has been applied to an object of application, as shown in FIG. 4, and refers to a sheet having no edges and an effective width L1.

[0020] <Wallpaper composition> FIG. 1 is a plan view showing a schematic configuration of wallpaper 1. As shown in FIG. Wallpaper 1 has a fixed dimension in the width direction, and can be applied up to both ends of the width direction, with the effective width L1 being set to 920 mm, for example, in accordance with the effective width of wallpaper specified in JIS A 6921. The longitudinal length of wallpaper 1 is equal to the length of the object to which it is applied. The wallpaper 1 is formed by laminating, for example, a base material, a foamed resin layer, a plain printed layer, and a surface protective layer in this order. Note that the configuration of the wallpaper 1 is not limited to this, and it can be formed using materials.

[0021] <How to provide wallpaper> Next, a method for providing the wallpaper 1 will be described with reference to FIGS. (manufacturing process) First, a sheet-like base material having a width of, for example, about 930 mm (hereinafter referred to as base material width L2) taking into consideration the effective width L1 (920 mm) of the wallpaper 1 and a margin α is prepared. A layer of a foaming agent-containing composition that will become a foamed resin layer is formed on one surface of the substrate, and the substrate is made into a sheet state.

[0022] Next, a plain printed layer is formed on the surface of the foaming agent-containing composition layer opposite the substrate by, for example, printing in a single color using a printing method. The printed layer is printed so as to be positioned at the center in the width direction of the substrate, and is printed over the entire printing width L3, which corresponds to the sum of the effective width L1 and the margin. Next, for example, an acrylic resin, a polyvinyl chloride resin, or the like is applied onto the printed layer to form a surface protective layer.

[0023] Next, the slit lines 3 are printed on the surface protective layer using a printing method. The slit lines 3 may be printed using, for example, a water-soluble ink. The slit line 3 is a line segment that indicates the cutting position when cutting out a sheet of paper with an effective width L1 from a roll-like sheet formed by stacking the above-mentioned layers on a substrate having a substrate width L2, and is printed at positions 460 mm apart on both the left and right sides in the width direction, starting from the center of the substrate in the width direction.

[0024] The layer of the foaming agent-containing composition is then heated to foam the layer to form a foamed resin layer, and then, if necessary, an embossing process is performed from the surface protective layer side using an embossing roll to form an embossed pattern. The sheet thus formed by laminating the above-mentioned layers on one side of the substrate is wound into a roll of cloth to form a wallpaper roll 10 having a constant width dimension as shown in FIG. 3(a). At this point, the wallpaper roll 10 is formed into a substrate having a substrate width L2, and the width of the wallpaper roll 10 is wider than the effective width L1.

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

[0026] Next, the wallpaper roll 10 having the base material width L2 is cut along the slit lines 3, and the members on the end side of the slit lines 3 are cut off on both ends. This results in the wallpaper roll 20 shown in Figure 3(b), in which a plain sheet having an effective width L1 is wound up in a roll of cloth. If slit lines 3 remain after both end portions of the wallpaper roll 10 are cut off from the slit lines 3, the remaining slit lines 3 may be erased at this point by rubbing with a sponge that has been moistened with water and appropriately wrung out.

[0027] Here, the printing width L3 is greater than the effective width L1. Therefore, the wallpaper roll 20 cut out from the wallpaper original roll 10 has a foamed resin layer, a printed layer, and a surface protective layer formed all over the width direction, and the wallpaper roll 20 has a plain, constant width dimension and is made of a sheet having an effective width L1 that allows construction to both width directions. In this embodiment, the slit lines 3 are printed on the surface protective layer, but if there is no surface protective layer, the slit lines 3 may be formed on the printed layer which is the outermost layer.

[0028] The wallpaper rolls 20 in the form of a piece of cloth having an effective width L1, with the ends cut off at the positions of the slit lines 3, are then shipped as finished products. The length of the wallpaper roll 10 may be left the same, and both ends or either one of the ends in the width direction may be cut off at the position of the slit lines 3 to form the wallpaper roll 20, or the sheet may be cut to a certain length and rolled up to form the wallpaper roll 20.

[0029] (Separation process) In the separating step, both end sheet portions (hereinafter also referred to as edge portions) of the wallpaper raw roll 10 cut off along the slit lines 3 are collected and separated. The edges of the sheet cut off at the slit lines 3 are made of a laminate of a foamed resin layer, a plain printed layer, and a surface protective layer, which are laminated in that order on a substrate. The manufacturer of the wallpaper roll 10 knows what materials are used to make these substrates and each layer. Therefore, they can be separated in consideration of the type of material. The separated materials can be reused after undergoing a prescribed treatment. For example, they can be used as cat litter.

[0030] <Construction method> When applying wallpaper 1 to an object, the installer cuts the wallpaper roll 20 into multiple sheets 21 according to the length of the object, as shown in Fig. 3(c). Here, the width of the wallpaper roll 20 is the effective width L1 (Fig. 3(b)). Therefore, the wallpaper roll 20 can be cut into sheets so that the longitudinal length corresponds to the height of the object.

[0031] Next, the first paper sheet 21a is attached to the object to be treated. Next, the second paper sheet 21b is placed, for example, on the right side of the paper sheet 21a, and the paper sheet 21b is attached so that the right side of the paper sheet 21a and the left side of the paper sheet 21b butt against each other (FIG. 4). Thereafter, the paper sheets 21 are attached in order in the same manner. As a result, a plurality of paper sheets 21 (three in FIG. 4) are applied to the object to be treated, that is, the wallpaper 1 (1a to 1c) having the effective width L1 is attached to the object to be treated.

[0032] Here, the paper sheet 21 cut out from the wallpaper roll 20 has no edge portions on either end in the width direction. Therefore, after the paper sheet 21 is attached to the object to be treated, a process of removing the edge portions is not required.

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

[0034] <Effects> (1) The width of the shipped wallpaper roll 20 is the effective width L1, and it does not have any edge portions. Therefore, the installer only needs to cut the wallpaper roll 20 longitudinally to a predetermined length to obtain the paper sheets 21, and then attach these to the object to be treated; there is no need to perform any process such as cutting off the edge portions.

[0035] Furthermore, since the paper sheets 21 are plain (wallpaper), even if they are not provided with pattern matching marks, the paper sheets 21 can be easily attached by simply butting the ends of the paper sheets 21 together and attaching them.

[0036] In addition, since the contractor does not need to cut off the edges when obtaining the paper sheets 21 or after attaching the paper sheets 21 to the object to be treated, there is no need to use cutting tape that is used when overlapping, and since there are no edges, the cost of using construction glue can be reduced.In addition, it is possible to reduce unnecessary materials generated during construction, such as the part of the sheet cut off at the slit line 3 that is ultimately discarded, and this can reduce waste generated during construction.

[0037] (2) The wallpaper 1 (sheet 21) has a plain design such as white, solid color, plain, grained, cloth-grained, patterned, woven, painted, striped, geometric, etc., and therefore does not need to be matched using a pattern matching mark. Therefore, since there is no unnecessary pattern matching mark, it is possible to reduce materials and simplify the manufacturing process.

[0038] (3) Because the paper sheets 21 do not have ears, the margin in the width direction of the base material and each layer when producing the wallpaper roll 10 need only be the minimum width required in the process of producing the wallpaper roll 10 to obtain wallpaper 1 with effective width L1. Therefore, compared to when ears are provided for the purpose of providing pattern matching marks, etc., the width of the ears required in the manufacturing process can be made smaller, and the various materials required during manufacturing can be reduced accordingly, resulting in a reduction in the effort and energy required for production.

[0039] Furthermore, since the edge portions are not provided, the wallpaper roll 20 can be made lighter and smaller, improving transportation efficiency and being environmentally friendly.

[0040] (4) After wallpaper roll 20 is cut out from wallpaper roll 10, wallpaper roll 20 is shipped without the ears. Therefore, the portions of wallpaper roll 10 that correspond to the ears, i.e., both ends of the sheet cut off at slit line 3, remain with the manufacturer.

[0041] Because the manufacturer knows the material of the sheet, they can separate and reuse the edges. If the edges were cut off by the installer, the installer would not know the material of the edges, would not be able to tell if they are PVC or other plastics, or would not be able to separate them because they are integrated with the paper, and would have to discard them as waste.

[0042] In the case of the wallpaper roll 20 according to this embodiment, the manufacturer is aware of the material of the edge parts and can separate them appropriately. Therefore, the edge parts that were previously discarded can be separated and reused, and modern environmentally friendly wallpaper can be obtained.

[0043] Incidentally, in the case of wallpaper with edges, assuming that the effective width L1 shown in Fig. 2 is 920mm, the print width L3 is 920mm or more, and the base width L2 needs to be about 960mm to 980mm. As a result, the width of the edges that are ultimately discarded is about 40mm to 60mm including the left and right ends, and about 5% of the width is discarded. According to the method for providing wallpaper according to this embodiment, the width of the edges that are discarded can be made smaller.

[0044] <Modification> (1) The width of the wallpaper 1 does not necessarily have to be 920 mm as specified by JIS A 6921, and may be any width, such as 300 mm, 600 mm, or 1000 mm. (2) The wallpaper roll 20 does not have ears. Therefore, in order to protect both ends of the rolled wallpaper roll 20 from damage, the wallpaper roll 20 may be packaged with cardboard or the like placed on both ends as earmuffs. (3) In the present embodiment, a case has been described in which neither the left nor the right end of the wallpaper roll 20 has ears. However, as shown in FIG. 5, a configuration in which one of the left or right end has ears and the other does not have ears may also be used.

[0045] In this case, the paper sheets 21 obtained by cutting the wallpaper roll 20 have an edge at one end in the width direction. Therefore, a process is required to cut off the edge before attaching the paper sheets 21 to the object to be treated, or a process is required to attach the paper sheets 21 to the object to be treated, overlap the paper sheets 21, and then cut off the edge at one end.

[0046] In this case, one end of the wallpaper roll 20 does not have an ear, so compared to when both ends have ears, it is possible to reduce material and energy loss, improve transportation efficiency, and reduce the amount of waste generated during installation. Also, because one end is an ear, when the wallpaper roll 20 is placed upright, it is possible to prevent the workable portion from being deformed or damaged by placing it with the ear side facing down.
