Abstract (en)

A process is described for freely steaming, i.e. under conditions of no mechanical stresses, a fabric (6) on a stretchable support (5). A fabric web is freely and continuously fed at an area where the support is stretched and, while passing through the steaming region, it is subjected to a mechanical thrust due to the support recovery. The contemporary effect of both actions enhances the fabric shrinkage. An apparatus for carrying out this process comprises, as a support, a stretchy web of fabric or mat that is wound, like an endless loop, about at least two rollers of different speed (1,2), between which there is the steaming zone. The roller being upstream of this zone has a peripheral speed greater than the roller downstream thereof, whereby the support is initially stretched and elongated until it releases when leaving the steaming zone.
