The piece, positioned in the center of the machine entrance, passes:
through a tensioner (see figure A, point 1),
in a fabric centering-stretching unit (fig. A, 2);
through a series of devices (selvedge unrolling, feelers and superchargers).
It is then dragged by two chains (fig. A, 3), equipped with plates with metal points on the
which are fixed the selvedges by the pressure of two brushes.
The first part of the machine is characterized by the presence of the articulated movement chains
to pin the patch at the height with which it appears at the beginning of the path. Chains can
be spaced from each other in such a way as to adapt them to the height of the rolling that takes place
in the second part of the machine.
The piece then passes through a steaming group, where a steaming tank (fig.
A, 4), placed under the belt, invests the fabric with its vapor, helping to make it uniform
and to equalize his height.
The fabric, heated and humidified, “relaxes”, allowing ironing in the narrower areas than
at the height set by spacing the chains.
An aspirator (fig. A, 5) removes excess steam.
Vaporized and humid, it passes into a drying field (fig. A, 6) formed by radiant batteries,
which make the fabric warm and dry when it comes out.

A cooling unit (fig. A, 7) brings the fabric to its final state, setting the height
set for the patch.
At the end of the process the piece is rolled up in large or small packs or folded in
based on the needs of the subsequent operations it will have to undergo.
