Method for the manufacture of a wound package with separate strands

摘要

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, andone positions the separation device in its second position.

1. A method for the manufacture of wound packages comprising a plurality of strands assembled with the help of a bobbin winder comprising a circular pirn battery equipped with at least a first spindle and a second spindle, in which each one of said first and second spindles is successively either at rest during a discharging phase or rotatable during a phase of spooling a wound package, the method comprising:
separating the strands that come from a spinneret into at least two blankets, each one of the blankets forming a roving of strands wound on the same wound package with the help of a shed winding device equipped with a traveler making it possible to deposit simultaneously on the surface of said wound package the strands that have been so separated, in which said wound package is supported by one of the spindles; starting movement of the circular pirn battery to switch one of the spindles from its spooling phase to its rest position, while the other spindle passes then from its rest position to its spooling position, wherein the traveler is separated from the surface of the wound package during startup of movement of the circular pirn battery; during the step of transitioning between the spindles, separating the rovings traveling from the spinneret to the surface of said wound package with the help of a separation device, wherein the separation device can occupy a first position in which it both separates the rovings from each other and maintains them in a separated position, and a second position in which it does not interfere with the trajectory of the rovings; bringing the traveler close to the surface of the wound package; and positioning the separation device in its second position, wherein the traveler intercepts the trajectory of each one of the separated rovings so as to enclose each one of the rovings within said traveler and allow the deposition of the surface of the wound package.
