Abstract
A method and apparatus for texturing continuous filament yarn wherein the yarn is fed at a controlled rate and under controlled tension by a pair of feed rolls into a confined crimping zone against a mass of crimped yarn therein, causing the yarn to collapse longitudinally to form crimps which become part of such mass. Heat and pressure are applied to the yarn mass in the crimping zone to plastically deform the yarn and partially set the crimps. The crimped yarn mass is then fed at a controlled rate by means of toothed rolls from the crimping zone into a setting zone. Heat and pressure are applied to the yarn mass in the setting zone to fully set the crimps. The yarn mass is moved through the setting zone by an endless belt having upstanding teeth that positively engage the yarn mass. The pressure applied to the yarn mass in the setting zone is substantially sufficient only to keep the crimps closed during the final setting thereof. The crimped yarn mass is then fed from the setting zone into a cooling zone. The yarn mass is cooled in the cooling zone to a temperature below that at which the yarn undergoes any molecular structural alteration in the absence of the application of a substantial force thereto. Finally, the yarn is withdrawn at a controlled rate from the cooling zone in continuous filament form. One of the feed rolls is mounted on one end of a yoke, the other end of which has an eccentric mounting shaft, the movement of which allows the feed rolls to be perfectly aligned in skewness and parallelism. Proper alignment of the crimping and setting chamber with respect to the other elements is accomplished by providing the frame with a number of alignment shoulders against which the chamber is set upon installation.
