A process for replacing a full wound bobbin on a bobbin winding machine with an empty bobbin support, wherein the yarn is wound onto the bobbin support in a bobbin winding zone by a traversing yarn guide. The process includes moving the traversing yarn guide out of the winding zone when the bobbin is completed, and into a cutting and clamping zone for severing the yarn. The yarn continues to be fed by the spinning machine, and will be collected by a suction pipe while the full bobbin is being replaced by an empty support. The suction pipe moves the yarn into a position to be clamped and cut by a cutting and clamping device, which rotates with the support for the bobbin. The yarn is guided to wind a reserve onto the end of the bobbin support before moving the yarn back into the winding zone to be wound by the traversing means onto the empty bobbin support. The invention also includes a device for carrying out the process of the invention. This device comprises a traversing yarn guide which is detachably connected to the yarn traversing means by a permanent magnet. When the full bobbin is completed, means are provided for detaching the yarn traversing guide from the yarn traversing means, and to move it into the cutting and clamping zone.
