Abstract (en)
[origin: EP0532458A1] The device contains a blowing nozzle (14) with a continuous yarn channel (16), into which air-supply bores (17, 18, 19) open laterally. The axes of the bores (17, 18, 19) are spaced from the axis of the yarn channel (16), so that the compressed air supplied forms an eddy in the yarn channel (16). A threading-in slot (24) likewise opens laterally into the yarn channel (16). The textured yarn, which leaves a heating zone downstream of a twist transmitter and belonging to the texturing apparatus, is guided through the yarn channel (16). The air eddy in the yarn channel (16) imparts a twist to the yarn running through the heating zone. This twist reduces the torsional moment which is present in the textured yarn leaving the said twist transmitter. With reduced torsional moment, the textured yarn can be further processed more easily. <IMAGE>
