The cylindrical Fora 10 τοη Fig. 1 contains a simple, Spirally wound band 12 made of woven or braided! textile material, whereby the shape is initially brought to the desired width or has to be cut to the required width on a relatively long cylinder of the twisted textile material.

Winding with natural rubber, synthetic Xautsohuk or another suitable impregnation agent impregnated and coated

It should be noted that the strip 12 is preferably of such a predetermined length or cut to such a predetermined length is that in the wound state its inner end 14 in radial alignment with the outer end 16, so that the »ylindrisehe Form 10 with a uniform bead and a uniform appearance! of layers at all points of the circumference.

This difference however, the location of the layers of the flanges 24 and 28 does not affect the usefulness of the compact; actually this can be done in In some cases the flange in the sealing ring is useful for "a" whom Sealing lip should form a special shape, for example in the form of the flange 28 in FIG. 4.

Due to the fact that each fabric layer of the pressed parts 22 continuously between the flanges 24 and 28 essentially as 4, a sealing ring from such a pressed part has no passage for liquid between the fabric layers and swisohen on the opposite sides of the binge.

The fact that a pressed part according to the invention is continuous all around (i.e. without a joint) forms a security against local sohwaohe places at any point of the circumference of the di oh- support ring.

Because the prefabricated part is formed from a cylindrical shape, the tissue in the sealing ring shows more strongly than any other Way, the threads are arranged in the same way at all points of the circumference which are thus also equally fixed at these points · Such a There is a uniformly directed arrangement of the threads, regardless of whether the fabric used is woven or fluted, and if so it is woven whether (permissible according to the invention) the material in the cylindrical shape has the winding straight or at an angle.

It is clear that since the fabric is initially in the press part i is in a long strip when pre-determining the amount of to make of sealing rings of uniform stacking height and minimal tiberaohufimaterials required tissue a considerable margin in terms of length, width and thickness of the strip required in the tissue Materials has to achieve the desired results.
