Abstract

A method is provided for operating a work station of a spinning or winding machine, wherein the work station includes a spinning device for producing a thread or a cop for delivering a thread, and a winding device for producing a bobbin on a tub. The winding device includes a swivel-mounted bobbin holder with a bobbin plate for receiving the tube and for catching the thread, a powered winding roller for rotating the tube or a bobbin, and a thread traversing device. A first suction nozzle is directed towards a circumference of a bobbin on the bobbin holder, and a second suction nozzle is arranged on the bobbin plate turned away from the bobbin and spaced from and directed counter to the first suction nozzle. To attaching a thread to an empty tube placed on the bobbin holder, the thread is arranged in the first and second suction nozzles so that the thread is tensed by negative pressure at least in the second suction nozzle. Subsequently, the tensed thread is captured between the first and second suction nozzles with a catching device in order to catch the thread for subsequent winding onto the empty tube.
