a suction box (fig. A, 2),
an air aspirator and relative
ejector (fig. A, points 3 and 4),
a final container of the fabric

and is operated by a three-way pedal
controls (fig. A, 6),

during which they are inserted
in the tube two or three pieces of fabric
tubular.
2. The second command, in the center of the
pedal board, is the stop button (Fig. B).
