Abstract
A method and an apparatus for the production of fancy yarn includes the supply of elongate fancy material pieces (17) by gas under pressure to suction-loaded spinning cylinders (10) which spin the fancy material pieces together with separately supplied basic yarn pieces to form fancy yarn. The fancy material pieces are flung by means of the gas under pressure, which is preferably generated in a jet injector (14), against a screen (7) which is located in the region of the nip between the spinning cylinders. Elongate fancy material pieces which have become rolled together during transport to the screen (7) are straightened out after impingement against the screen (7) by the suction prevailing in the nip of the spinning cylinders (10) whereby the fancy material pieces are given the desired elongate form in the fancy yarn.
