Title
(EN) SPUNBOND TOWER WITH AN ELECTROSTATIC DEVICE
(FR) TOUR SPUNBOND A DISPOSITIF ELECTROSTATIQUE
Abstract
(EN) The invention relates to a spunbond tower that includes a die (103), a device (106) for cooling the filaments formed by the die, a device (107) for stretching the cooled filaments, a system (108) for forming a non-woven web (110) on a mat, said system including an electrostatic device (117) and a dehumidifier mounted at least on a formation air inlet between the bottom of the stretching device and the top of the formation system.
(FR) Cette tour spunbond comprend une filière (103), un dispositif (106) de refroidissement des filaments formés par la filière, un dispositif (107) d'étirage des filaments refroidis, un système (108) de formation sur un tapis d'un voile de nontissé (110), ce système comprenant un dispositif (117) électrostatique et un déshumidificateur monté au moins sur une entrée d'air de formation entre le bas du dispositif d'étirage et le haut du système de formation.
