Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to the underlay material used when pasting wallpaper on walls, and in particular, it is used by laying it under the wallpaper when cutting the boundaries of the wallpaper without gaps.
When stacking wallpaper and cutting with a cutter without any gaps,
This article relates to an underlay material used to avoid cutting the paper on the surface of gypsum board, which is the base material for wallpaper.

[Conventional technology and its problems]

The process of pasting the border portion of wallpaper is shown in FIGS. 6 and 7. Wallpaper must be pasted without any gaps at the border. In order to achieve this, as shown in the figure, the wallpaper 1 is wrapped at the boundary portion, the wrapped portion is cut with a cutter, and the adjacent wallpapers are cut without any gaps. However, when cutting the wallpaper in this state, if a hard underlay material is not used for the wallpaper, cuts will be made on the surface of the underlay material along with the wallpaper. Gypsum board is often used as a base material, and gypsum board is made by pasting paper onto the surface of plaster, and the paper on the surface is cut together with the wallpaper. Gypsum board with cut paper tends to peel off after wallpaper is adhered, and wallpaper adhered to a base material in this state has the disadvantage that the paper peels off along with the wallpaper 6 months to 1 year after adhesion. A particular problem is that wallpaper tends to shrink a little after being glued, so if the paper to which the wallpaper is glued is not firmly bonded, the cut edges will warp in the direction of peeling, causing the cut edges to peel off. There is a drawback that it becomes easier. In order to prevent the cut edges of the wallpaper from peeling off, a hard underlay material 2 is laid over the lap part of the wallpaper 1, as shown by the chain line in FIG.
It is recommended to cut the wallpaper 1 while preventing cuts. However, the reality is that this method is not necessarily used in the wallpaper bonding process. This is because laying and removing the underlayment material 2 takes a lot of effort, and the unit cost of construction increases significantly. For example, when gluing wallpaper without using an underlay material, one person can paste 100m in a day, but if an underlayment material is used, the number decreases to 60 to 70m. The reason why work efficiency decreases when using underlayment material is because
Since hard materials such as stainless steel are used for the underlayment,
This is to ensure that the long underlayment is precisely positioned under the glued wallpaper. By the way, if the wallpaper that is layered on top at the wrap part is directly layered on the wallpaper below, the glue on the back will adhere to the surface of the wallpaper below, so as shown by the two-dot chain line in Figure 7, a thin layer of composite material is applied to the bottom surface. The resin sheet 5 is temporarily attached. This thin synthetic resin sheet is attached together with a device that applies glue to the underside of the wallpaper, and when it is wrapped, it prevents the glue from sticking to the surface of the wallpaper below, and after cutting the wallpaper, it is removed and The wallpaper is glued to the substrate. This thin synthetic resin sheet is attached at the same time as wallpaper gluing, so it can be attached to wallpaper easily and without much effort. Therefore, if the underlay material can be temporarily adhered to one side of the wallpaper in a similar manner, the underlay material can be used easily and efficiently. However, the underlay material
It is useless to cut wallpaper with a cutter, so you need to use something made of hard material. Hard sheet materials cannot be easily bent, so they can be glued to wallpaper with a wallpaper gluing machine. difficult. Also, after gluing, wallpaper is folded and stored until it is glued to the wallpaper, as shown in Figure 8, but wallpaper with hard sheet material glued is stored in this state. There is a drawback that it cannot be done. If a thin sheet material is used so that it is easy to bend, it will be cut with a cutter along with the wallpaper and will no longer function as an underlay material.

[Purpose of this idea]

This invention was developed with the aim of solving this drawback, and the important purpose of this invention is that it can be easily adhered to wallpaper, has good bendability in the adhesive state, and is also easy to cut with a cutter. To provide an underlay material for interior wallpaper that is difficult to use and can be effectively used as an underlay material.

[Means to solve conventional problems]

The underlay material for interior wallpaper of this invention is laid between the back side of the wallpaper wrap and the base material, and is used when cutting the wrap of the wallpaper with a cutter. The underlay material 2 is a sheet material that is harder than the wallpaper 1 and difficult to cut with a cutter, and this sheet material is formed into a band shape so that it can be laid along the lap part of the wallpaper 1. . Further, the underlay material 2 has countless horizontal slits 3 cut in it in the horizontal direction so that it can be bent easily without being cut by the cutter. They are provided adjacent to each other and separated by a predetermined interval.

[effect]

The underlay material 2 of the interior wallpaper 1 of this invention is provided with the horizontal slits 3 in a direction that intersects the cutting direction of the wallpaper 1, so the underlay material 2 of the wallpaper 1 for interior use is laid under the wallpaper 1.
When used as an underlay material 2, the horizontal slit 3
It can be used in almost the same condition as the underlay material 2 without the horizontal slits 3 without reducing the strength of the material. That is, when the wallpaper 1 is used as the underlay material 2, the cutter for cutting the wallpaper 1 moves on the upper surface of the underlay material 2, perpendicular to the horizontal slits 3 or intersecting the horizontal slits 3. However, in this direction, the cutter moves across the width of the portion where the horizontal slits 3 are hardly cut, and the horizontal slits 3 do not reduce the strength of the underlay material 2. However, when the underlay material 2 is rolled up, the actual width of the underlay material becomes significantly narrower due to the horizontally extending horizontal slits.In other words, it can easily be rolled up like a narrow synthetic resin sheet. Can be bent. Therefore, like a thin synthetic resin sheet, it can be easily and efficiently adhered to the edge of wallpaper using a gluing machine, and furthermore, the glued wallpaper can be folded and stored as shown in FIG. Therefore, the underlay material of this invention can be easily adhered to wallpaper, has good bendability in the adhesive state, and is difficult to cut with a cutter, so it can be effectively used as an underlay material.
