Title (EN) VENT TYPE EXTRUDER AND METHOD OF MANUFACTURING CABLE JACKET USING THE SAME
(FR) EXTRUDEUSE DE TYPE À ÉVENT ET PROCÉDÉ DE FABRICATION DE GAINE DE CÂBLE L'UTILISANT
Abstract:
(EN) A cable jacket extruder (12) comprises a chamber (12), a feeding port (14) disposed at one end of the chamber (12), an extruding screw (16) disposed inside the chamber (12), a pathway (18) connected to an outlet at another end of the chamber (12), wherein a vent (20) is defined on the pathway, and a nozzle (22) connected to the pathway (18). A tandem-type cable jacket extruder is also provided. The tandem-type cable jacket extruder comprises a first chamber (116) and a second chamber (118) connected in tandem via a pathway (122), a vent (120) disposed on the pathway (122), a feeding port disposed at one end of the first chamber (116), and an extruding screw disposed in each of the first and second chambers (116,118). A method for manufacturing a cable jacket is also provided.
(FR) L'invention concerne une extrudeuse (12) de gaine de câble comprenant une chambre (12), un orifice d'alimentation (14) disposé en une extrémité de la chambre (12), une vis d'extrusion (16) disposée à l'intérieur de la chambre (12), une voie (18) reliée à une sortie en une autre extrémité de la chambre (12), un évent (20) étant défini sur la voie, et une buse (22) reliée à la voie (18). L'invention concerne également une extrudeuse de gaine de câble de type tandem. L'extrudeuse de gaine de câble de type tandem comprend une première chambre (116) et une deuxième chambre (118) reliées en tandem par l'intermédiaire d'une voie (122), un évent (120) disposé sur la voie (122), un orifice d'alimentation disposé en une extrémité de la première chambre (116) et une vis d'extrusion disposée dans chacune de la première et de la deuxième chambre (116, 118). L'invention concerne également un procédé de fabrication d'une gaine de câble.
