Abstract
Means for positioning the end of yarn on a cross-wound bobbin on a textile machine. The machine has a traveling service mechanism that services the bobbins individually at winding heads of the machine. A yarn end take-in device in the form of a suction tube with a concave surface facing the bobbin and a nozzle against the bobbin searches for, takes in and draws off a yarn end from the bobbin. A yarn guiding device, in the form of an inclined slot in the suction tube or a pivoted guiding rod, guides the yarn end against a side of the bobbin. A yarn guide element on the winding head, on the creel or on the servicing mechanism is positioned with an oblique surface extending to an end adjacent the juncture of the bobbin side and bobbin tube to guide the yarn to the juncture for forming a yarn end reserve thereat.
