Abstract:
Winding device for threads (F) from V-creels (10) having bobbins (24) from which the threads (F) are drawn via pre-looping bars (15) through a comb (48), and are wound up on a winding shaft (21) of the winding device, with the pre-looping bars (15) being wound with longer contact length of the threads near the winding device and less contact length of the threads at a distance from said winding device and with a degree of looping of the threads being centrally adjustable, with at least one measuring device (41) being located beyond the comb (48) in a running direction of the threads (F) for determining the thread tension in the threads (F), and with central adjustment of the pre-looping bars (15) being controllable according to the result of measurements by said measuring device, characterized by the fact that the pre-looping bars (15) of a side (10') of the creel (10) are subdivided into successively positioned functional groups (40, 40'), to one of which is allocated the measuring device (41) for determining thread tension in threads (F) of the one group, and wherein the central adjustment of the one group is controllable in accordance with the result of the measurement, and wherein all of said pre-looping bars of the one group are coupled at their respective ends with adjusting strips (46, 46'), each of the adjusting strips being acted upon by a stepping motor (47, 47') to effect the adjustment of the one group.
