Abstract
A method and an apparatus for stuffer box crimping a multifilament yarn, wherein the yarn is conveyed into a crimping device in two steps. In the first step, the yarn is taken in by a conveying fluid stream of a first feed nozzle at a yarn intake speed. In the second step the yarn is advanced by a conveying fluid stream of a second feed nozzle at a second yarn conveying speed into the crimping device. In this process, the second yarn conveying speed is at least the same as or greater than the intake speed.
