Title (EN) PROCESS AND ARRANGEMENT FOR PRODUCING AIRBORNE FIBRES
(FR) PROCEDE ET AGENCEMENT DE PRODUCTION DE FIBRES AERIENNES
Abstract: front page image
(EN)The present invention relates to a process for producing a flow of airborne fibres, characterized by the following stages: a) a continuous length (2) of a thread bundle of fibre material is fed from a stock (1) of fibre material through a roll press (4), which rotates at a rate of feed and with the thread bundle held fast in the nip between its rollers (11, 12), b) on emerging from the roll press (4), individual fibres are broken off from the thread bundle by means of a tearer (5), c) the individual fibres broken off by the tearer are carried away from the tearer by means of an air flow.
(FR)L'invention concerne un procédé de production d'un flux de fibres aériennes, caractérisé en ce qu'il consiste a) à envoyer une longueur continue (2) d'un faisceau de fils de matériau fibreux, provenant d'un stock (1) de matériau fibreux, à travers une presse à cylindres (4), qui tourne à une vitesse donnée d'alimentation, avec le faisceau de fils coincé dans le pincement des cylindres (11, 12), b) à casser, à la sortie de la presse à cylindres (4), des fibres individuelles à partir du faisceau de fils au moyen d'une effilocheuse (5), c) et à transporter au moyen d'un courant d'air les fibres individuelles provenant de l'effilocheuse.
