(57) [Abstract] [Problem] The present invention relates to a knife and a knife for pasting wall wallpaper. [Solution] An underlay trowel (6), which also serves as a slide, is fixed to the front of the cutter knife and below the arm (1) in a reverse T shape, and a roller (3) is mounted on it. ) Is provided on both sides of the roller shaft (4), and a spring (5) is provided above the center of the roller shaft (4).

Description

[Detailed description of the invention]

 In this invention, when the wallpaper seams on the wall surface and the overlapping surface are cut, the cut end of the wallpaper on the overlapping bonding surface is sandwiched between the underlay iron 6 and the roller 3, and the grip 9 is pulled down. The wallpaper is cut by the thing, and the pulled wallpaper is cut while the roller 3 holds down the cut wallpaper. By using the folding blade 7, the blade edge can be easily replaced. The vertical fixing part 2 of the blade keeps the fixing direction of the arm 1 and the underlay trowel 6 parallel to the cutting direction of the blade's wallpaper, and the cut line is cut in a straight line, so that it does not cut even when the wall foundation is stuck.

[Technical field to which the invention belongs] [0001] The present invention is a cutting tool for cutting a seam-lapped surface of a wallpaper without cutting flaws on the wall surface undercoat.

[Prior Art] In the past, the pasting of seams and the pasting of pasted wallpaper are usually cut from the surface of the pasted wallpaper with a cutter knife or the like.

[Problem to be Solved by the Invention] In the invention, when wallpapering and connecting to a conventional wall surface, the present invention is to cut a heavy-weighted center line with a cutter knife, a blade, etc. It was pasted together with. Currently, the base wall material becomes a plaster board (lime board) and cuts into the base wall together with the wallpaper, so there was a problem with the deterioration of the wallpaper and the durability of the wall. Therefore, after cutting, peel off the laminated surface and reinforce the cuts in the base wall with tape, etc.Also, before cutting, peel off one end of the splicing overlay of the wallpaper and insert the underlay plate and paste it. After matching and cutting, the underlayment board is removed and the cut surfaces are butt-joined again. Therefore, except for the drawbacks, the present proposal is to cut the wall only without cutting the wall underlayer and without reinforcing treatment of the underlayer wall so that the seam can be easily pasted.

[Means for Solving the Problem] The means for solving the problem will be described with reference to the drawings. Secure the underlay iron 6. C) The upper and lower parts of the underlay iron 6 and the lower part of the arm 1 in front of the folding blade 7 are sandwiched, and the left and right two-wheel cut wallpaper pressing feed rollers 3 are provided. D) The arm 1 that serves as a bearing for the roller shaft 4 is provided with a spring 5 for adjusting the thickness of the wallpaper and the presser foot in the upper center of the roller shaft 4.

[Embodiment of the Invention] Since the present invention has the above-mentioned structure, when using this, 1) the underlay trowel 6 is first put in a place where the seam wallpaper needs to be cut. Insert a cut edge and insert the underlay iron 6 under the wallpaper along the cut edge. 2) Insert the cut edge of the cut wallpaper between the underlay iron 6 and the roller 3, and insert the underlay iron. The wallpaper is cut by pulling it toward you while closely contacting 6 with the wall base surface. 3) Roller 3 turns to the front and feeds while sandwiching both scraps, so only the wallpaper can be cut smoothly.

[Advantages of the Invention] Therefore, it is not necessary to attach a cutting flaw to the base wall surface, to insert an underlay plate for cutting, and to reinforce the base wall or to apply repair.
