The fabric to be dried, in rolls or in flaps, is placed in the center of the machine entrance and passes:
through an expanding device (see figure A, point 1)
between two supercharging introducing cylinders (fig. A, 2) which arrange the pieces
on the conveyor belt (fig. A, 3); here a feeler controls the guide cylinder which holds the
conveyor belt in central position;
a pre-drying chamber (fig. A, 4) receives the ribbon and dries the fabric by means of blowers (fig.
A, 5), without subjecting it to the vibrations present in the following ones
vibration drying chambers (fig. A, 6), here special drying blowers are added
pneumatic blowers (fig. A, 7), with controlled pulses, which shake the fabric with strong flows of
air alternating from below and from above.
The pneumatic blowers placed under the belt are offset from the upper ones, belt and fabric receive
so in continuous alternating downward and upward thrusts, which almost force them to
arrange themselves in a serpentine.
A cooler (fig. A, 10) receives the fabric at the end of the path, which is then deposited
on a conveyor belt (fig. A, 11) which ends with a bundler (fig. A, 12) of the pieces.
The heat generators (fig. A, 8) and the relative fans are installed alternately above the machine
(fig. A, 9). An exhaust blower expels humidity and provides adequate air exchange.
