  • Patent number: 8882019
    Abstract: 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.

  • Patent number: 7614580
    Abstract: A leasing device including at least one first part connected to a frame element of a reeler and at least one second part including a mechanism for depositing and guiding at least one thread. The first part and the second part are connected to one another such that the second part occupies a first working position, in which the thread can be deposited in the form of a reel, and a second position, in which the second part is separated from the first part, corresponding to a maintenance phase of the second part.
