Title
(EN) METHOD AND APPARATUS TO MECHANICALLY SHAPE A COMPOSITE STRUCTURE
(FR) PROCEDE ET APPAREIL POUR METTRE MECANIQUEMENT EN FORME UNE STRUCTURE COMPOSITE
Abstract
(EN)
An apparatus for forming a shaped fibrous nonwoven structure including a delivery system adapted to provide a high speed composite stream comprising thermoplastic polymer fibers and a secondary material. The apparatus also includes a movable collection device having a collection surface which intersects the composite stream, and at least one deflector to mechanically redirect at least a portion of the composite stream. Further the deflector moves in synchronization with the movable collection device, such that the composite stream is collected on the collection surface forming a fibrous nonwoven structure having at least one non-linear edge.
(FR)
La présente invention concerne un appareil pour former une structure non tissée fibreuse de forme particulière qui comprend un système de distribution conçu pour fournir un flux de matériau composite se déplaçant à grande vitesse et comportant des fibres polymères thermoplastiques et un matériau secondaire. L'appareil comprend également un dispositif d'accumulation mobile qui comporte une surface d'accumulation croisant le flux de matériau composite, et au moins un déflecteur pour rediriger mécaniquement au moins une partie du flux de matériau composite. En outre, le déflecteur se déplace en synchronisation avec le dispositif d'accumulation mobile, de sorte que le flux de matériau composite soit accumulé sur la surface d'accumulation et forme une structure non tissée fibreuse possédant au moins un bord non linéaire.
