Title
(EN) PROCESS AND DEVICE FOR PRODUCING SPUNBONDED FABRICS
(FR) PROCEDE ET DISPOSITIF POUR PRODUIRE DES NON-TISSES
Abstract
(EN)
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.
(FR)
Procédé pour obtenir des non-tissés à partir de polymères synthétiques, selon lequel les fils constituant le non-tissé, après la filature et le refroidissement, sont déposés en large chaîne de fils sur une surface en mouvement, par exemple sur une bande de transport. Avant d'être amenés sur la surface en mouvement, les fils sont soumis à l'action de rouleaux à dents sans contact direct, qui les peignent dans le but de les distribuer de façon uniforme dans la direction axiale des rouleaux et qui les soumettent à des ondulations et simultanément à une extension.
