The other machine (fig. C), more productive than the previous one, provides more contact points of the fabric on the cardoons placed on a single drum. The fabric to be subjected to this process passes into a tank (fig. C, 1), where it is soaked in water at room temperature or, in some cases, at 50°C in which auxiliary products can be dissolved; between the tensioning cylinders (fig. C, 2), it slides on the drum (fig. C, 3) where contacts with the cardoons occur.
Four pairs of cylinders (fig. C, 4), placed above the drum, approaching it,
they increase the contact area between thistles and fabric while when they move away this area decreases until it disappears.
The striated piece then passes into a tray (fig. C, 5), becoming still soaked in water; it is then rolled up and remains in this state for a period of 24 hours, always moving, to obtain better fixation and shine of the hair.
