Abstract (en)
[origin: WO2020130962A1] The invention is related to a core-less yarn winding machine (10) that comprises a winding group (20) having a winding shaft (23) on which the yarn obtained from the bobbin is wound and consists of a winding group body (21) that in order to realize the winding of the yarn on said winding shaft (23) moves the winding shaft (23) forwardly and moves the winding shaft (23) backwardly after the winding process is completed; a winding control center (50) having a diameter-density control wheel (55) that compresses the wound yarn underneath together with the start of the winding process; a yarn transfer group (60) having a primary forming lateral surface (24) and a secondary forming lateral surface (47) in a manner that creates the required winding form and that takes and transfers the wound yarn to the press group (80), and a press group (80) that gives form to this yarn.
