Abstract

In order to make possible an automatic replacement of full bobbins in a spooling device with continuous thread supply, the supplied thread from the traversing thread guide is lifted and directed to a cutting and suction device. The supplied thread is cut and sucked in. The full bobbin is allowed to roll away from the spooling position on inclined rolling rails. Through the rolling motion of the full bobbin the fall of an empty bobbin into the spooling position is triggered and the supplied thread is attached to the delivered empty bobbin. A device for carrying out this method has a movable thread guide rail, a thread cutting device, a thread suction nozzle, rolling rails for the full bobbin, inclined rails for the empty bobbin and a thread guiding arm which wraps the thread around the empty bobbin.
