<p>Process for producing spunbonded fabrics from synthetic polymers, in which, after spinning and cooling, the yarns which form the spunbonded fabric are placed widthwise, in the form of a warp, on a moving surface, for example a conveyor belt. Before the yarns are placed on the moving surface, they are waved and extended simultaneously by the action of combing, non-contacting toothed rollers which distribute the yarns uniformly in the axial direction of the rollers.</p> |
