ABSTRACT:
An arrangement for texturizing continuous filament threads using a heated flowing medium comprises a housing which includes a feeding portion, a treatment portion and a crimping portion. The crimping portion includes a stuffing chamber in which the threads are longitudinally compressed to produce crimping of such threads. The crimping portion has openings through which the medium fed into the stuffing chamber with the threads can escape from the stuffing chamber. The crimping portion accommodates a plurality of lamellae which are arranged in a star-like configuration and jointly bound the stuffing chamber. A jet introduces a gas stream into the stuffing chamber in a direction which differs from the direction of advancement of the threads through the stuffing chamber, the gas stream penetrating between the lamellae into the stuffing chamber. At the commencement of the crimping operation, this gas stream causes initial retardation of the continuous thread passing through the stuffing chamber. This action of the gas stream can be continued even during the normal operation of the crimping arrangement.
