Abstract
The method for relaxing knitted fabrics according to the invention uses humidity, heat and agitation of the fabric. Said agitation is caused by projecting the fast-advancing fabric against a rigid support on which the then nontensioned fabric piles up. The projection of the knitted fabric is obtained by driving said fabric by friction and without slipping, by means of a movable element of projection into the outlet zone from which the fabric is projected against a receiving zone of the support, which receiving zone is situated close to the outlet zone of the projecting element and substantially transversely to the direction of projection. The movable element of projection is a movable belt turning over two cylinders of which one at least is a driving cylinder, whose driving speed can reach 600 meters/minute.
