Abstract: The proposed winding support makes it possible, for the first time, to protect the thread reserve and final thread reserve on a winding support during the attachment of the spools, while still leaving them easily accessible after disassembly. At the same time, the revolving bobbins of two spooled winding supports come to practically abut each other directly.

Abstract: The invention concerns a yarn bobbin with a rotationally symmetrical body the outside of which forms a surface which carries the yarn and which has a longitudinally protruding collar at one end. The aim of the invention is to design a bobbin of this kind which has the advantages of prior art bobbins but which, when wound, can be stacked with other, similar, bobbins without the yarn being damaged or snagged. The invention achieves this by virtue of the fact that the bobbin has, at its end with the yarn uptake, an additional collar which has the same external dimensions as the internal dimensions of the collar at the other end of the bobbin but is staggered radially inwards with respect to the yarn uptake, the collar being fitted with a yarn-reserve groove.
