Abstract

Se proveen un proceso y un aparato mejorados para la formación de una tela fibrosa por extrusión de filamentos continuos adecuados para su utilización en usos finales de no tejidos. Se extruye por fusión un material polimérico termoplástico procesable por fusión para formar una línea devanadora multifilamentar, se lo enfría y enrolla alrededor de por lo menos dos rodillos espaciados de tracción accionada y rodeados por una envoltura antes de ser recogido para formar un tejido y se lo adhiere para formar un producto no tejido por extrusión de filamentos continuos. Los rodillos de tracción ejercen una fuerza de tracción sobre la línea devanadora multifilamentar de manera de lograr el estiramiento de una línea devanadora multifilamentar fundida antes de que se complete la solidificación. La envoltura posibilita la auto-hilación de la línea devanadora alrededor de los rodillos de tracción. Un chorro neumático ubicado en el extremo de salida de la envoltura contribuye al contacto de lalínea devanadora mutifilamentar con los rodillos de tracción para facilitar la imposición de una fuerza de tracción uniforme y expele la línea multifilamentar en su sentido longitudinal hacia un soporte donde se la recoge. Se posibilita la formación de una tela no tejida por extrusión de filamentos contínuos de manera eficiente.An improved process and apparatus are provided for the formation of a fibrous web by extrusion of continuous filaments suitable for use in non-woven end uses. A melt processable thermoplastic polymeric material is melt extruded to form a multifilament winder line, cooled and wound around at least two spaced driven pull rollers and surrounded by a wrapper before being picked up to form a fabric and processed. Adheres to form a nonwoven by extrusion of continuous filaments. The pull rollers exert a pulling force on the multifilament winder line so as to achieve the stretch of a molten multifilament winder line before solidification is complete. The wrap enables self-spinning of the winder line around the drive rollers. A pneumatic jet located at the outlet end of the casing contributes to the contact of the mutifilamentary unwinder line with the traction rollers to facilitate the imposition of a uniform traction force and expels the multifilamentary line in its longitudinal direction towards a support where it is collected. . The formation of a non-woven fabric is made possible by extrusion of continuous filaments efficiently.
