Title
(EN) FIBER CLUSTERS MOLDING PROCESS AND EQUIPMENT
(FR) PROCEDE ET EQUIPEMENT DE MOULAGE UTILISANT DES AMAS DE FIBRES
Abstract
(EN)
A process and apparatus for molding recyclable cushions is disclosed. The cushions are molded by a process comprising filling (30) a mold with polyester fiber clusters, encapsulating the fibers clusters with a scrim sheet or adhesive, closing the mold, advancing the mold to a heating station (50) where hot air is forced through the mold, advancing the mold to a cooling station (70) where cool air is foced through the mold, and subsequently releasing the molded part from the mold.
(FR)
On décrit un procédé et un appareil pour mouler des coussins recyclables. Les coussins sont moulés suivant un procédé consistant à remplir (30) un moule avec des amas de fibres de polyester, à entourer les amas de fibres par une feuille de tissu ou un adhésif, à fermer le moule, à avancer le moule vers un poste de chauffage (50) où de l'air chaud est forcé à travers le moule, à avancer le moule vers un poste de refroidissement (70) où de l'air froid est forcé à travers le moule et, ensuite, à libérer la pièce moulée du moule.
