If the fabric presents defects higher than the processing tolerance, the operator
communicates the defects to be removed on the pieces still to be woven directly to the weaving mill, while for
as regards the other types of defects (spinning, twisting, etc.) the employee will communicate them
to the technical office. At the end of the check, the patch is marked on the head on the reverse side, usually
with the following data: the name of the manufacturer, the progressive number (serial number) of the piece, the name
or article number and finished height. Any other data are at the discretion of the manufacturer. These
data can be imprinted on the piece by means of a hot-applied label or a special marker
indelible.
