ABSTRACT:
A device for finding, extracting and temporarily positioning the end of the yarn in cops. More particularly, a device that uses single-cop compartments, which move forward in steps, and wherein the cops lie projecting from both ends of the compartments and already correctly oriented. The part on the end of the bobbin is affected by three actions to extract the end of the yarn, two of them being mechanical and the other being pneumatic. Subsequently all the wound yarn is affected by a sucking action so as to pick up the end of the yarn with certainty, wherever it may be. The operations are carried out in four successive stations, wherein the cops are kept in rotation between suitable mandreltailstock groups except in the third station, where the cops are halted.
