Description

  The present invention relates to a slitter that is mounted on a wallpaper pasting machine and cuts both ends of the wallpaper.

  Conventionally, in the pasting work of wallpaper, two kinds of construction methods, that is, stacking construction and butt construction, have been performed. The former is a method in which adjacent wallpaper is stacked and pasted, and a ruler is applied to the overlapped part and cut with a cutter from above. The latter is a method in which both ends of the wallpaper are cut with a slitter at the time of gluing. It is the method of constructing by matching the cut surfaces. In this butt construction method, the wallpaper is cut by a slitter. Also, in the former method of overcutting, only the paper portions at both ends of the wallpaper are cut in advance by a slitter. Thus, in either construction method, it is necessary to adjust the width of the wallpaper, and a slitter has been used for adjusting the width by cutting both ends of the wallpaper.

  A conventional slitter will be described with reference to FIG.

  The slitter is attached to the cloth original fabric side of the gluing machine main body, and the cutting tool is rotated by receiving a driving force from the gluing machine with a gear. An upper blade 51, a lower blade 52, a lower blade boss 53, The upper blade mounting shaft 54, the lower blade mounting shaft 55, the pressing roller 56, the lower blade fixing stay 57, the upper blade fixing stay 58, and the like.

  The slitter for the wallpaper pasting machine is substantially parallel to each other, and has a pair of cuttings composed of an upper blade 51 and a lower blade 52 arranged on each of the front surface side and the back surface side of the wallpaper on a mounting shaft at a position orthogonal to the wallpaper feeding direction. The pair of upper blades 51 and lower blades 52 are pressed against each other on both sides in the wallpaper feeding direction, and a guide roller (not shown) is attached to the lower blade mounting shaft 55 of the lower blades 52. The lower blade mounting shaft 55 is supported by the lower blade fixing stay 57 by a bracket (not shown), and a pressing roller 56 and a spring 59 as pressing means are disposed in the vicinity of the lower blade 52. ing. The upper blade 51 is mounted on the upper blade mounting shaft 54, and the upper blade mounting shaft 54 is supported by the upper blade fixing stay via frames at both ends and brackets.

  The lower blade mounting shaft 55 of the lower blade 52 is driven from the gluing machine side through several gears, and the upper blade mounting shaft 54 of the upper blade 51 rotates through a gear interlocked with the lower blade mounting shaft 55. It is supposed to be. In this conventional slitter, the lower blade 52 is pressed against the upper blade 51 by a spring 59 interposed between the pressing roller 56 and the lower blade 52, and the positions of the upper blade 51 and the lower blade 52 are changed. The cutting width of the wallpaper was variable.

  Then, when the upper blade 51 and the lower blade 52 come into contact with each other and the wallpaper passes through the rotating portion, the wallpaper is cut.

In order to make it easier to move and position the upper and lower blades as a slitter for wallpaper pasting machines, a method for positioning the upper and lower blades by providing a rail parallel to the cutter axis has also been proposed. Yes. (See Patent Document 1)
Furthermore, in order to prevent the upper and lower blades from swinging, it has been proposed to form a boss member for fixing the blade integrally with the blade shaft. (See Patent Document 2)
On the other hand, as for the wallpaper cutting method, when cutting thick wallpaper, the wallpaper is inclined and cut so that the back of the wallpaper does not come out from the surface, so the upper part of the cutting blade is tilted outward. A slitter configured as described above has also been proposed. (See Patent Document 3)
