Abstract (en)

Warp yarns (3) are unwound from a supply unit (2) and longitudinally move towards a threads-interlacing area (8) at which a dragging roller (11) rotates to advance the textile product (9) toward a winding reel (15). A winding torque WT applied to the winding reel (15) is modulated by repeated winding adjustment cycles, to keep a target value WFtv of a winding traction force provided on the textile product (9) downstream of the dragging roller (11). Each winding adjustment cycle comprises: acquiring a winding rotation speed of the winding reel (15); acquiring a dragging rotation speed of the dragging roller (11); detecting an instant winding diameter WD of the textile product (9) in the winding reel (15); and applying an instant value of the winding torque WT calculated by the formula: WT = WFtv * WD / 2.
