Description

Folded cellulose cloth

The invention relates to a folded-up one, preferably made up of several by means of edge embossing with one another
connected layers of existing cellulose cloth.

Such cloths are already known. You can find extensive ones as handkerchiefs, facial tissues, mouth towels, etc. Use and are usually housed in stacks of ten or more wipes in a common package and acted in this form.

Depending on the intended use, the tissues consist of several, for example three or even four, layers of lightly creped or embossed cellulose wadding, which is referred to as "tissue wadding". The individual layers of the ¥ atte are laid on top of one another without binding agents and are only connected to one another by suitably arranged edge embossing .

The type of cleavage of such cloths is of increasing importance too, because on the one hand the neat overlapping of the folded towels in the stack depends on it and on the other hand also the ease with which the wipes removed from the pack are unfolded before use can.

From the German patent specification 441.137 a type of folding for such tissues, which is hardly used today, is known, which consists in that each sheet is folded into a number of superimposed strips which are the same width except for the two narrower outer strips. In this way, a zigzag folded structure is created, the zigzag layers of which are approximately the same width and which has a narrower side flap at least on one side. This side flap is intended to be used to grip the cloth when it is unfolded and it has the advantage that it is particularly easy to grasp. The disadvantage of such a folding manner, however, is that the stack of wipes superposed where the side flap is located, more apply than elsewhere, so that it is difficult to use such wipes evenly and firmly with packaging materials, such as cellophane or the like. To envelop.

Most of the cellulose tissues on the market today are square blanks, which are first folded along a center line to form a narrower strip and this is then laid twice along a transverse line and finally laid four times along a further transverse line. In order to make it easier to open the wipes, they often have a cutout on one side that is roughly in the form of a finger grip. Wipes folded in this way are of the same thickness at all points, so that they can be conveniently put together in a stack and packaged. They are, however, in need of improvement with regard to the type of opening, since the mentioned punching is not always easy to find, especially in a hurry. In addition, the towels are made with special care because the folded cloth takes different size when the track runs in the production of towels inside the machine.

In this prior art, the task is a to propose folded cellulose cloth, which on the one hand in the folded state at all Places is approximately evenly thick, which on the other hand is easy to grasp and open, and that too it is insensitive to the running of the path during its manufacture, as well as when the path is running no deviation in the shape and dimensions of the collapsed Tuches occurs.

This object is achieved according to the invention in that the cloth consists of a Z-shaped folded strip that doubles along a transverse center line and is laid four times along other lines. Also in the production of this cloth it is advantageous to starting from a square cut, although other, for example rectangular cuts are also possible are. The Z-piping is carried out in such a way that the both edges of the Z-shaped folded strip are each folded over to the middle of the strip.

The subject of the invention is described below with reference to attached drawing explained in more detail.

In Fig. 1, a handkerchief 1 is shown, which consists of several layers of cellulose wadding arranged one above the other (tissue fatte). The individual layers are connected to one another by an embossed edge 2. The handkerchief 1 has the two fold lines 3 and h , along which the edge strips 5 and 6 are folded over in a Z-shape. The resulting strip 7 is shown in FIG.

During the production of the cloth, the strip 7 is then placed twice along the line 8 and the resultant Laminate is finally laid four times along line 9. The cloth is then folded up far enough in order to combine several of them into a stack 10, which then in a known manner with cell glass, Foil or similar pigments is packed.

It can be seen from FIG. 3 that the pre-folded type of folding has numerous advantages. On the one hand, the stack 10 is uniformly thick at all points, so that it can be packed cleanly and without problems. Furthermore, the stack on all sides folded and thus sharp edges, with the result that the stack on all sides a clean and makes non-ausgefranzten impression. Finally, FIG. 3 shows that the top cloth in each case can be easily removed, since it is easily possible to grasp the strip 5 lying on top and then shake the entire cloth apart.

A particularly noteworthy advantage is the specified type of folding with regard to the production speed. When operating cellulose cloth folding machines it has been shown that the clean and run-free guiding of the web only up to a certain maximum

Running speed is flawlessly possible. At running speeds above 200 meters per minute, it cannot be completely ruled out that the very soft cellulose web in the machine runs by a small amount and that several meters have to be enforced until the existing regulating devices have returned the web to its starting position. If this occurs with the type of folding proposed here, the width of the wipes remains the same, since the distance that exists between the fold lines 3 and 4, respectively, by corresponding folding plates. Folding rolls is set in the machine. The only consequence of the running is that the outer edge 11 wanders out, for example, from the center of the strip 7 and is placed closer to the fold line 3, and that accordingly the edge strip 6 becomes wider and consequently its outer edge also wanders closer to the fold line 3. The overall dimensions of the finished folded cloth are not changed, so that the stack symmetry and all other advantages of the cloth are fully preserved.
