Abstract (en)
Improved apparatus and method for forming packages of crosswound direct-spun yarn, such as partially oriented polyester yarn. The method permits the consistent winding of large packages which have low banding defect level and can be unwound more readily in subsequent processes such as false twist texturing. The apparatus comprises specific digital microcomputer systems (11), for controlling the traverse rate of a grooved roll winder (8). The process comprises controlling the traverse rate of the grooved roll (8) in a specific manner, dependent upon the properties of the yarn being wound.
