Patent

CA 2128695

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 protuding 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 (1) has, at its end with the yarn uptake (2), an additional collar (3) which has the same external dimensions as the internal dimensions of the collar (4) at the other end of the bobbin but is staggered radially inwards with respect to the yarn uptake, the collar (4) being fitted with a yarn-reserve groove (6).
