only be controlled or influenced between neighboring helices in gap 10 rather it can also move better under the paper web 19 than in the case of wire belts in which the paper web 19 lies directly on the supporting surfaces 17 the fiber segments 21 can consist of plastic such as in particular aramids polyaryletherketones polyamide polyester or viscose however one can also employ fiber segments 21 of natural material such as wool or cotton or even a mixture of natural and synthetic fibers thus one is free to select fiber segments 21 which are compatible with the belt design and end use so long as the fiber segments are capable of application to the host belt in order to secure the fiber segments 21 reliably on the supporting surfaces or their edge areas these surfaces should be provided with a roughening 24 which can be caused for example by electric spark erosion or even chemically or mechanically mechanical roughening 24 can be effected for example by the tool used in manufacturing the broad supporting winding legs 5 according to u s patent application no 602 413 for accomplishing this the tools will preferably be provided with appropriately machined surfaces with respect to the roughening of the surface it will be understood that the need for such roughening or the degree thereof will be determined by material selection at the least the surface must be free and clean of yarn sizing and machine oils fig8.
