Title
(EN) APPARATUS AND DEVICE FOR THE PRODUCTION OF NONWOVENS
(FR) APPAREIL ET DISPOSITIF DE PRODUCTION DE NON-TISSES
Abstract
(EN)
In an apparatus and a method for the production of nonwovens (1) at high operating speeds using at least one carding machine (2) and at least one conveyor belt (4), it is provided that an air-permeable conveyor belt (4) is used, and that, in the transition regions (6) between the carding machines (2) and the conveyor belt (4), an underground vacuum is applied to the conveyor belt (4) between the nonwoven (1) and the conveyor belt (4) to remove an air film generated at high transport speeds.
(FR)
Dans un appareil, et selon un procédé de production de non-tissés (1) à très hautes vitesses de fonctionnement utilisant au moins une cardeuse (2) et au moins une bande de manutention (4), une bande de manutention perméable à l'air (4) est utilisée et, dans les zones de transition (6) entre les cardeuses (2) et la bande de manutention (4), un vide souterrain est appliqué à la bande de manutention (4) entre le non-tissé (1) et la bande de manutention (4) afin d'enlever un film d'air produit à des vitesses de transport élevées.
