Abstract

Method and device for winding continuous threads or yarns to produce yarn bobbins having thread reserves, wherein the bobbins are automatically changed, without the need for a catch slot, to achieve automatic, loss-free and highly reliable changing of full bobbins with empty bobbins, and the full bobbins include a thread reserve lap which is easily accessible on the bobbin edge and having a thread which runs from the thread reserve into the bobbin.
