ABSTRACT:
A cooling apparatus of a high speed false texturing machine in which a so-called surging phenomenon is prevented, yarn breakages are not increased, unevenness in yarn dyeing does not occur, and deterioration of crimp characteristics in obtained textured yarn is prevented. A false texturing machine includes a false twisting device (6) for imparting twists to a yarn (2), a heating apparatus (3), disposed upstream from the false twisting device (6), for heat setting twists that run back along the yarn (2), and a cooling apparatus (4, 5), disposed between the heating apparatus (3) and the false twisting device (5), for cooling the yarn. The cooling apparatus (4) has a plurality of partial cooling plates (8). A yarn pressing member (9) serves to insert the yarn (2) into a space between the adjacent partial cooling plates (8) beyond a common contacting line of the adjacent partial cooling plates (8).
