The fabric passes:
through the tensioning cylinder (fig. C, 2) and the center piece (fig. C, 3),
it is transported by a series of rubber-coated inlet and outlet cylinders (fig. C, 4).
Its pressure on the raising drum is regulated by four dancing cylinders (fig. C, 5).
Two brushes (fig. C, 6) for cleaning the thistles are placed under the drum.
A special vacuum cleaner (fig. C, 7) removes the fluff extracted from the thistles.
A brush (fig. C, 8) with relative vacuum cleaner finishes the hair straight, at the end of the path.
When finished, the piece is folded or rolled up on a special beam.
The effect of raising the pile and counter-pile is given by the drum which can rotate in two directions, with
speed higher or lower than that of the fabric.
The intensity of the raising depends on
the pressure of the dancing cylinders on the fabric;
the condition of thistles. The new and very elastic ones produce a more intense raising.
