(FR) AMELIORATIONS RELATIVES A DES STRUCTURES DE FIBRES DE POLYESTER NON TISSEES COLLEES
Abstract: front page image
(EN)A batch process and apparatus are provided for molding fiberballs, comprising load-bearing fibers and binder fibers, into shaped articles, preferably using hot air within a perforated mold to allow circulation of the air through the fiberballs. The techniques are particularly adapted to molding cushions of varying shapes and sizes, without excessive wastage of material, using relatively simple flexible equipment.
(FR)Procédé et appareil pour le moulage de boules de fibres par lots, comprenant des fibres porteuses et des fibres de liaison, en articles ayant une forme particulière. Ledit procédé utilise de préférence de l'air chaud à l'intérieur d'un moule perforé pour permettre à l'air de circuler à travers les boules de fibres. Ces techniques sont particulèrement adaptées au moulage de coussins de diverses formes et dimensions; elles permettent d'éviter un gaspillage excessif de matière et d'utiliser un équipement flexible relativement simple.
