Abstract

Machine has a mechanism which opens up and prepares the strands of material used in the manufacture of the filter. The rolled up strand passes between two pairs of pressure rollers and the speed with which the first pair of rollers rotates is less than that of the second. When the material is stretched outwards it passes through tow pairs of aperture rollers, at least one of which in each pair is ribbed or threaded.
