The devices have 1 to 6 channels. The path described relates to a single channel.
The patch:
it is put into the machine by an auxiliary circular reel controlled at variable speed (A, point 1);
passes by a patch guide comb (fig. A, 2) with a safety stop device through
a funnel (fig. A, 5)
is dragged together with the bath through a U-shaped tube (fig. A, 3),
reaches the relaxation chamber (fig. A, 4) where it floats in the bath without any tension e
through a reel it continues in its path, of which are adjustable (fabric speed from 10 to
200 meters per minute), the thrust of the circulation pump and the rotation speed of the reel
(fig. A, 1).
The mechanical action exerted on the fabric by the overflow (0.4 Bar) is less than that caused by the jet
(1.5 Bar) and for this reason it is preferable for dyeing very delicate fabrics.

A reel controlled external to the machine (fig. A, 11) unloads the pieces into a special tank
perforated, equipped with wheels to move the pieces to subsequent processes.
The machine is equipped with:
heat exchanger (fig. A, 6), for heating the bathroom;
circulation pump (fig. A, 7) for the overflow tank, connected to a special one
adjustable damper (fig. A, 8), to establish the flow rate of the bath.
A drain valve (fig. A, 9), on the bottom of the tank, allows the residual bath to escape.
An external barrel equipped with a special drain (fig. A, 10) feeds the dye bath e
auxiliary substances.
