Abstract (en)

[origin: WO2013017694A1] The invention relates to a winding device for continuously winding a fiber strand. The winding device has a rotatably supported winding revolver (2) having two rotationally drivable winding spindles (3.1, 3.2), which are retained on the winding revolver in a protruding manner and which each have a winding sleeve (5.1, 5.2) and a catching apparatus (4.1, 4.2) On the winding revolver (2), two severing apparatuses (7.1, 7.2) are associated with the winding spindles (3.1, 3.2). The severing apparatuses cause the fiber strand to be severed when the fiber strand is transferred from one of the winding spindles having a wound full spool to other winding spindles. A traversing apparatus (8) is arranged upstream of the winding spindles and has a traversing thread guide (9), which can be moved parallel to the winding spindles and which can be positioned outside of a traversing stroke in order to transfer the fiber strand. In order to obtain defined severing of the fiber strand at relatively slow process speeds, each severing apparatus (4.1, 4.2) has a blade (27) and a locking means (26) associated with the blade, wherein the fiber strand (42) is guided by the blocking means (26) before the severing and wherein the fiber strand (42) causes a release of the locking means (26) when a minimum tensile force is reached and can be fed to the blade (27).
