Abstract (en)

[origin: EP1129976A2] In a take-up winder for elastic yarn, a yarn moved to a bobbin end due to a yarn transferring operation forms a bunch winding at the bobbin end of a full package. The number of windings in the bunch winding, however, may be insufficient. Additionally, the mere formation of the bunch winding makes it difficult to pick up a yarn end from the package during a subsequent step. An end of an elastic yarn Y wound into a yarn layer P of a package falls from the yarn layer P onto a position of a bobbin Bf which is separate from a yarn layer-formed position, and the yarn end is wound around the bobbin Bf three or more times to form an elastic-yarn package. Additionally, the end of the elastic yarn Y wound into the yarn layer P of the package falls from the yarn layer onto the position of the bobbin which is separate from the yarn layer-formed position, and the yarn end is then wound on the bobbin once or more and adheres to an end surface Pa of the yarn layer, thereby forming an elastic-yarn package. <IMAGE>
