摘要

In textile production the yarn is being withdrawn from cross-wound packages in warping and weft insertion. During unwinding there appear forces in the yarn that are approximately proportional to the square of the unwinding velocity. During unwind the yarn tension is not constant, but it oscillates within some interval. This is especially noticeable in over-end unwinding from a static cross wound packages, where the yarn is being withdrawn with a high velocity in the direction of the package axis. Even when the yarn is not strongly stressed, so that the tension does not exceed a few percent of the breaking strength, the yarn still can break sometimes. This is why we think that a cross-wound package is not an ideal form of a package and that such packages are not always made without flaws.
