Abstract
A method for crimping yarn wherein the yarn is fed into a compaction channel of a stuffer box to obtain uniform crimping, and the crimped yarn is pre-set and guided to the outlet of the stuffer box by a pre-setting fluid. A pre-setting and guiding chamber of the stuffer box has a cross-section of generally polygonal shape that is larger than that of the compaction channel.
