Abstract: On a texturing machine such as a false twist machine a broken strand of thread or yarn is restarted during a winding process by means of a uniquely formed end cap which mounts the take-off end of the winding spool to the take-up holder arm. The end cap includes a shoulder extending in an axial direction beyond the rim of the take-off end of the spool and a hook-like tab extending outwardly over the shoulder which picks up the broken yarn end and guides the yarn around the shoulder portion for several rotations. After wrapping the yarn around the shoulder traversing of the yarn along the spool is carried out until the interrupted yarn package is completed. When the package is complete the spool is removed from the winding machine, leaving the end cap on the machine. During inspection the aforesaid two ends are tied together completing the repair of the broken end.
