Abstract

L'invention concerne un procédé de production de paquets de fil cellulosique. Le procédé consiste à passer au moins un premier et un second groupes de filaments à travers une chambre commune, à enchevêtrer le premier groupe de filaments à un premier emplacement pour former un premier fil, à enchevêtrer le second groupe de filaments à un second emplacement pour former un second fil, et à enrouler au moins les premier et second fils autour d'une partie centrale commune. Les fils peuvent être enroulés autour de différentes sections, ou autour d'au moins une section commune de la partie centrale. Les fils ne sont pas enchevêtrés ou torsadés les uns avec les autres sur la partie centrale, ce qui permet aux fils d'être déroulables individuellement à partir de la partie centrale.
