According to a practical embodiment of the invention, if such fiber webs are applied to the skin, the cell glass layer has at least one, they have their own back layer opposite the fabric.

This creates a multilayer sheet created that "breathes", but the wave-forming property is retained.

The surface of the absorbent fleece which is absorbent or is made absorbent can, for example, be known per se Be metallized if this is necessary for medi ' sanitary or hygienic purposes, e.g. as a wound cover, should be appropriate.

Depending on the intended use of the proposed multilayer sheet The wave-forming cell glass layer can also be designed in the form of a multilayer intermediate layer if this should prove to be desirable for mechanical or other reasons.

To achieve a desired cooling effect, especially on wounds, the proposed multilayer sheet-like structure in a manner known per se with a dark, preferably violet one Equip paint. It is also possible to use only the wave-forming cell glass layer ao to equip or layers with such a dark, preferably violet color.

To produce a test model you go z. B. Proceed as follows: A soaked Fiber fleece, for example 10 χ 12 cm in size, as is placed on a glass plate, on top of which with a cellophane film protruding slightly at the edges, without creases arrested. Another fiber fleece is deposited on this smooth cellulose film without creases. One lets Dry this fiber fleece, cellulose glass fiber fleece combination in the open air on an absorbent pad. After the drying process has ended, the following experiment can be carried out:

A sufficiently large glass plate or another completely smooth plate is filled with a puddle of water each of about 1.0 ml. If one area of water is covered with a fiber fleece alone, this remains Adhere to the surface like chattered, even after the plate has been raised. If you go in the same Way before with a multilayer sheet-like structure according to the invention, this falls after standing up the plate from this after a short time. You can repeat this experiment using the control fleece still adheres, while the multilayer sheet according to the invention every time falls after the plate is raised. One can see the movement processes leading to the replacement of the observe the combination mentioned.

Some embodiments of the invention are shown schematically, for example, in the drawing.

F i g. 1 shows a first embodiment;

F i g. Fig. 2 shows a second embodiment;

F i g. 3 shows a third embodiment;

Fig. 4 shows a further embodiment;

F i g. 5 shows a further embodiment.

In the exemplary embodiment shown in FIG. A wave-forming Zellgjasschicbt is denoted by 6 (solid line), while an _{absorbent layer of fiber fleece or the like connected to it by binding agent 0 {} l the like, is denoted by 7 (dashed line).

The embodiment of FIG. 1 is shown in FIG. 2 modified so that in addition to the wave-forming cell glass layer 6 and the absorbent layer 9, a back layer 8 (back layers) is provided (dash-dotted Line).

In the embodiment of FIG. 3 is next to Wavy cell glass layer 6 and the back layer 8 (back layers) a layer 10 is provided which has channels through which the moisture can get to the cellular glass layer 6. The channels in the form of perforations, needles, etc. serve to support the penetration of moisture to the wave-forming cell glass layer 6.

In the embodiment of FIG. 4 are next the cell glass layer 6 (solid line) and the back layer 8 (dash-dotted line) two more Layers 11 and 12 provided, can be formed as described above and the shown as dashed and dash-dotted lines are.

F1 g. 5 shows a further possible modified embodiment in which instead of one cellular glass layer 6, two cellular glass layers 6 and 6 α are provided, and between these two cell glass layers 6, 6 α a further intermediate layer 13 (dash-dotted line) is provided, as well as an under layer (layers) 14 (double-dotted line) and a front layer 15, which can be made of a fiber fleece or the like, as explained above (dashed line).

To produce the multilayer sheet-like structure, the wave-forming cell glass layer and the absorbent layer (s) are connected to one another by a calendering process, wherein small amounts of binders can be used.

A back layer (back layers) can also be carried out at the same time through the aforementioned work process be connected to the cellular glass layer.

The procedure here is, for example, that a suction fleece is removed from a supply roll, from a second supply roll a wave-forming cellular glass layer and from a third supply roll the back layer is peeled off, a suitable one on the way to the uniting device Piiidmittel is introduced between the layers or applied to them and then through simple Pressure, if necessary with the application of heat, turns the layers into a continuous immediately usable web are combined with one another.
