Abstract

L'invention concerne un dispositif de frisage par compression d'un fil multifilament synthétique, dans lequel ce fil est compressé à l'aide d'un système de texturation, jusqu'à l'obtention d'un enchevêtrement de fil. Cet enchevêtrement de fil est ensuite refroidi à l'aide d'un système de refroidissement puis démêlé jusqu'à l'obtention d'un fil frisé. Dans la zone de transition entre ce système de texturation et ce système de refroidissement, l'enchevêtrement de fil parcourt une ligne de chauffe, sensiblement définie par la distance entre une sortie d'enchevêtrement du système de texturation et une partie réception d'enchevêtrement du système de refroidissement. Selon cette invention, un moyen de réglage permet de régler la distance entre cette sortie d'enchevêtrement et la partie réception d'enchevêtrement.
