Method of texturizing continuous filament threads

A method of operating a texturizing nozzle for texturizing continuous filament threads by means of a heated flowing medium, comprising the steps of feeding the threads to be crimped, together with the medium, into a stuffing chamber of a crimping portion of a housing for the threads to be longitudinally compressed therein to produce crimping of such threads and for the medium to escape from the stuffing chamber through openings provided in the crimping portion;

• and introducing a gas stream into the stuffing chamber in a direction differing from the direction of advancement of the threads through the stuffing chamber as a single gas stream which enters the stuffing chamber directly sideways substantially transversely to the stuffing chamber to achieve a retardation of the threads during their passage through the stuffing chamber only at the commencement of the crimping operation, said crimping portion including a plurality of lamellae extending in the advancement direction and arranged in a radiating pattern to jointly bound the stuffing chamber, said introducing including blowing the gas stream between said lamellae as said single gas stream;
• selectively switching the gas stream on at the commencement of the crimping operation and off after damming of the threads has been initiated in the stuffing chamber;
• supplying the threads to the housing;
• and supplying the heated flowing medium to the housing.
