The fabric passes:
through the tension cylinder (fig. C, 2) and the piece center (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 aspirator (fig. C, 7) eliminates the fuzz extracted from the thistles.
A brush (fig. C, 8) with relative aspirator finishes the hair on the right side, at the end of the path.
Once processing is completed, the piece is stacked or rolled on a special beam.
The effect of raising the hair and against the hair 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 the thistles. The new and very elastic ones create a more intense raising.
