Each braid layer 2 or 4 consists of miteinan- 5 braid layer 2 and a second bobbin head, the outer one of the braided bobbin straps 2 'or 4'. The Geßechtslage 4 applies. With each bobbin head aligned perpendicular to the bobbin straps 2 'or 4', several parallel threads 2 ″ are made up of a continuous hose aligned, so many bobbins run around the middle diameter 4 ″ together. The drawing shows a special opening for the hose around it, as clearly shown by the figure, that the outer braid layer 4 in the braid layer formed by this bobbin head is made up of more bobbin straps 4 'than contains the straps, with half of these coils in the inner braid layer 2 bobbin tapes 2 'has a clockwise direction, the other half counter-clockwise. Furthermore, it can be seen that, in contrast, the clockwise direction. The bobbins are each to have straps 2 'of the inner braid layer 2 more two in several on the bobbin head around one thread 2 "each than the straps 4' have 15 horizontal axis rotatably mounted, driven the 4". In the example shown, cross disks with four radial ones, mutually at 90 °, encompass the bobbin straps 7! the inner braid layer 2 arranged staggered slots. Each cross disk has three threads 2 ″, and the bobbin lace 4 'also takes a braid layer 4 on the outside of the middle bobbin head and two threads 4 ″. opening clockwise and one of this opening

The braid layers 2 and 4 are different 20 counterclockwise revolving coil. Each impregnated. While the inner braid layer 2 with the coil is impregnated on its way around the middle material, the head opening from one cross disc to the next outer braid layer 4 is impregnated with a material and is carried out in addition to the circulation that is affine to the rubber material on the outside - A radial jacket 5 behaves around the middle clapper head opening. This provides a particularly good pendulum movement, so that all strands of thread or bobbin ribbon coming from a spool adhesion of the individual hose layers to each other, especially the core 1 made of rubber, on the inner braided layer 2 and the outer jacket 5 applied by a bobbin head are intertwined.

The production of the hose gel head shown for the inner braid layer 2 is the same in such a way that first the core 1 is extruded because it is less penetrated on an orbit, and preferably directly on the knife than those of the bobbin head for those thorn 6, on which they then with the braid 35 the outer braid layer 4. You can therefore snow 2,4 and the intermediate layer 3 as well as the ler run around the middle clapper head opening Outer jacket 5 is provided. It is left as it is, as the bobbins of the clapper head drive that around the steadily by several ring-shaped outer braid layer 4, which with a rotary clapper heads Itindurch moving soul 1 on the number of at least 25 rev / min.
