The invention relates to a method for producing a continuous thread, wherein a multiplicity of continuous filaments is formed by mechanically drawing a multiplicity of strands of melted thermoplastic material (s), especially glass, and said filaments are combined to form at least one thread. The inventive method is characterized in that the tension exerted by a group of some or all of the filaments is constantly verified whereby it is detected if said tension falls below a predetermined value.
La présente invention a trait à un procédé de fabrication d'un fil continu dans lequel on forme une multiplicité de filaments continus par étirage mécanique d'une multiplicité de filets de matière(s) thermoplastique(s) fondue(s), notamment le verre, et l'on rassemble ces filaments en au moins un fil. Ce procédé se distingue particulièrement par le fait que l'on contrôle en permanence la tension exercée par un ensemble de certains ou de la totalité de ces filaments, en détectant le passage de cette tension en dessous d'une valeur prédéterminée.
