Title: Method and apparatus for stuffer box crimping a yarn

Abstract: A method and an apparatus for stuffer box crimping a spun multifilament yarn, wherein the yarn is packed in a crimping device to form a yarn plug. After cooling the yarn plug, it is unraveled into a yarn. In so doing, the position of the unraveling point is adjusted by varying the withdrawal speed of the yarn. At the same time when the withdrawal speed is varied, a signal is generated for controlling at least one of the parameters of the crimping device, which influences the formation of the yarn plug, so that it is possible to produce a uniformly crimped yarn.
