Abstract
A method for spreading a tow of textile non-braided filaments, preferably chemical or inorganic fibres comprises providing a tow of textile non-braided filaments extending along its own main direction and having a section transverse to the main direction with a predetermined thickness and a predetermined width, feeding the tow along a travel path and spreading the tow in order to increase its width and reduce its thickness, defining a spread tow. The step of spreading the tow includes immersing the tow in a bath and generating in the bath a sequence of transverse waves crossing the tow transversely to the main direction in order to separate and place the individual filaments side by side, thereby spreading the tow, wherein the tow entering the bath and/or the spread tow extracted from the bath is/are unsized.
