Abstract
(EN)
An apparatus for continuously cutting filamentary tow (2) into fibres and condensing the cut fibres to rod form, the apparatus comprising: a tow inlet feeder and a cut fibre exit gas jet arranged in-line and separated by ledgers (58); a knife blade (60) rotatably mounted for periodic passage between adjacent ledgers (58) to intersect tow (2) passing therepast and cut it into fibres; and a unit for separating air from the cut fibres and condensing the latter to rod form including an air permeable f rusto-conical screen (21) formed of a mesh having openings of size 0.088 mm to 0.841 mm.
(FR)
La présente invention a pour objet un appareil permettant de couper de manière continue un câble filamentaire (2) en fibres et de condenser les fibres coupées en forme de tige, l'appareil comprenant : une canalisation d'entrée de câble et un jet de gaz de sortie de fibres coupées disposés en ligne et séparés par des moises (58) ; une lame de couteau (60) montée rotative pour le passage périodique entre des moises adjacentes (58) pour croiser le câble (2) qui y passe et le couper en fibres ; et une unité pour séparer l'air des fibres coupées et condenser ces dernières en forme de tige comprenant un tamis tronconique perméable à l'air (21) formé d'une maille ayant des ouvertures d'une dimension de 0,088 mm à 0,841 mm.
