Method for the manufacture of wound packages comprising a plurality of assembled strands, characterized in that one separates the strands coming from a spinneret into at least 2 blankets, in which each one of the blankets is wound on the same wound package with the help of a traveler, said wound package supported by one of the spindles, one proceeds to start the movement of the circular pirn battery in such a way as to switch one of the spindles from its spooling phase to its rest phase, during this transition phase between the spindles, one proceeds to a separation of the rovings traveling from the spinneret to the surface of said wound package with the help of a separation device, one brings the cursor closer to the surface of the wound package and the latter then intercepts the trajectory of each one of the separated rovings in such a way as to enclose each one of the rovings within said traveler, and one positions the separation device in its second position.
Method for the manufacture of wound packages comprising a plurality of strands (5) assembled with the help of a bobbin winder (1) comprising a circular pirn battery (2) equipped with at least a first spindle (3) and a second spindle (4), in which each one of said first and second spindles (3, 4) is successively either at rest, i.e., during a discharging phase, or rotatable, i.e., during a phase of spooling a wound package, characterized in that
Method according to one of the preceding claims, characterized in that the separation device (15) is positioned in the vicinity of the trajectory of the ravings in such a way as to, on the one hand, intercept their trajectory, and on the other hand, push back least a first roving of at least a second roving on both sides of a median plane.
Spooling device (1) for carrying out the method according to one of the preceding claims comprising essentially a frame, in which this frame comprises a circular pirn battery (2) that can be moved in rotation with respect to the frame, in which said circular pirn battery (5) is made of at least two spindles (3, 4) that are each adapted to support at least one wound package, each one of the spindles (3, 4) rotatable about a first axis substantially perpendicular to the diameter of the wound package in such a way as to draw and wind simultaneously at least two rovings in the form of a wound package of separate rovings, and a shed winding device (6) equipped at least with a traveler (7), which makes it possible to deposit on the surface of the wound package the rovings separated from each other, characterized in that it comprises, in addition, a separation device (15) that can occupy a first position in which it allows, on the one hand, the separation from each other of the ravings that travel from a spinneret (11) to the traveler (7), and on the other hand, maintaining them in a separated position, and a second position in which it does not interfere with the trajectory of the rovings.
