The invention concerns a method for making continuous yarn from filaments (12) which consists in depositing at the surface of at least part of the filaments (12) a mixture in liquid state, before assembling them into at least one yarn, said method comprising successive steps which consist in: continuously soaking an absorbent mat (10) with the mixture in liquid state; removing continuously at least part of the mixture with a rotating roller (11) in contact with said mat (10); and depositing on the filaments (12) while they are being drawn said mixture from the sizing roller (11). The invention is characterised in that the mat (10) is driven in rotation along an axis parallel to that of the sizing roller (11). The invention also concerns a product comprising a yarn resulting from said method.
