(57) The description is of a rotary head numbering machine to mark lengths on fabrics.
It is suitable to effect the aforesaid marking directly on the side edge or selvage
of the fabric, particularly for long pieces of fabric.
The numbering head, in accordance with the invention, is able to overcome the problems
of traditional machines which, by not permitting the printing of the length on the
fabric, required the application of labels to indicate the , length which involve
long and expensive operations and due to their thickness, cause a deformation of the
piece which resulted in an impression on the fabric.
The numbering head (T) subject of this invention permits the length to be printed
directly on the fabric (2) and for this purpose is equipped with at least three printing
discs (10A, 10B, 10C) for the units, tens and hundreds respectively, capable of being
positioned, by suitable control means (55,14) in the printing position synchronously
with the rate of advancement of the fabric (2).
