Title
(EN) MANUFACTURING METHOD FOR A VOLUMINOUS FABRIC WITH A SMOOTH SURFACE AND THE RELATED EQUIPMENT
(FR) PROCEDE DE FABRICATION DE NON TISSES EPAIS A SURFACE LISSE ET EQUIPEMENT ASSOCIE
Abstract
(EN) A manufacturing method for a voluminous fabric with a smooth surface, a high compression resistance, a small residual deformation after repeated compression and with a minimum thickness of 2 mm consists in that a strip of planary fabric, produced by bonding of a fibrous web, composed of perpendicular or random oriented fibres in its whole thickness, is split by cutting, resulting in at least two layers of planary voluminous fabric products with a smooth surface, parallel to the plane of the planary fabric strip. A device for manufacturing voluminous fabrics with a smooth surface consists of a pair of conveyors (1 and 2) whose vertical and horizontal position to each other is controllable, and also of at least one endless steel blade strip (3) with a cutting edge, guided in between the outlet of the conveyors (1 and 2), a system of guide rollers (13) and supported by a guide slat (4), and further of at least two winding devices (6 and 8). The tangents to the roller of the winding devices (6 and 8) pass through the outlet of the feeding conveyors (1 and 2) at an angle of 15 to 45°. The steel blade strips with the cutting edges can be arranged in cascade perpendicular to the plane of the guide roller system (13), their distance from each other and from the feeding conveyors (1 and 2) being controllable.
(FR) L'invention porte sur le procédé de fabrication de non tissés épais présentant une surface lisse, une forte résistance à la compression, une faible déformation résiduelle après de multiples compressions, et une section transversale d'une épaisseur minimale de 2 mm, consistant à découper une natte plane consistant sur toute son épaisseur en fibres collées orientées perpendiculairement ou aléatoirement de manière à obtenir au moins deux couches épaisses présentant une surface lisse parallèle au plan de la natte plane. L'invention porte également sur une machine servant à la fabrication de non tissés épais à surface lisse comportant: deux convoyeurs (1 et 2) dont la position relative est réglable verticalement et horizontalement; au moins une lame d'acier en bande continue (3) à bord tranchant guidée entre les sorties des convoyeurs (1 et 2) et son système (13) de rouleaux de guidage montés sur une plaque de guidage (4); et au moins deux dispositifs de bobinage (6 et 8). Les tangentes aux rouleaux de bobinage (6 et 8) coupent la sortie des convoyeurs (1, et 2) sous un angle de 15° à 45°. Les lames d'acier en bande à bord tranchant peuvent être disposées en cascades perpendiculairement au plan du système (13) de rouleaux de guidage, et séparées les unes des autres et des convoyeurs (1 et 2) par des distances réglables.
