Bonumwerke, Tigges & Winckel, Langenberg / RhId. Placement ruler for trimming wallpaper.

The innovation concerns a steel ruler with a profiled handle, which is preferably made of wood, plastic or metal and an exchangeable one or two-part steel ruler for trimming freshly attached wallpaper, wall decorations, Advertising or information signs, etc.

Up to now, wallpapers were either "scissors" or with a knife cropped at the table. In the case of butted wallpapers, for example, it is necessary that the cut edge is absolutely straight. That is difficult and with scissors only by a specialist, with a cleaver only possible with absolute straightness of the ruler.

In order to remedy this drawback, it is proposed according to the invention that the wallpaper after applying the paste uncut, overlapping, to stick to the wall and then with the new Ruler and sharp knife, make the necessary cut to yourself execute overlapping paths at the same time, using the ruler is added depending on the length.

The cut of the wallpaper placed one on top of the other becomes absolutely tight, as it is never possible with previously cut. It is also time-saving, as only 50 fo the previously usual cuts are now made. . .

The steel rulers (b) are exchangeable and preferably about 40 cm long. The head sides (e) are bevelled on both sides so that the ruler can be pushed under the ceiling on uneven ceilings.

The handle (a) has a bulge (f). This bulge (f) causes when tightening the screw (d) that the steel ruler adapts itself and an angle of 150 ° is formed. This means that the ruler only rest on the two outer sides when it is placed which almost completely prevents slipping.

The head shape of the screw (d) is adapted to the bulge (f) so that it is possible to use two-part steel rulers that be pushed from both sides against the square head of the screw (d) and are securely in place by tightening the wing nut * If an outer edge is damaged, only half of it needs to be replaced, and it is also easier to replace.
