The fabric passes:
by a small stenter, which regulates the height of the fabric in the weft direction;
by a steam humidifier and a heated drum, which uniformly humidify the fabric;
through a device made up of a very thick special rubber mat (see figure A, point 2) which slides transported by three tensioning cylinders (fig. A, 3), controlled by the respective tension regulators (fig. A, points 4 and 5 ).
The moistened fabric passes between the belt and the heated cylinder (fig. A, 1), with a contact arc that is greater than 180°.
The desired return is proportional to the belt pressure and the speed between the rubber belt and the heated cylinder.
