UNWINDING AND BALLOON-SEPARATING DEVICE FOR TWISTING/DOUBLING MACHINES FOR YARNS

摘要

Unwinding-separating device (10) for twisting/doubling assemblies (20) for yarns (11) wound in bobbins (12), in which each of the yarns (11) defines a first inner segment (11a), and a second outer segment (11b) that under normal working conditions constitutes the balloon. The unwinding-separating device (10) is assembled rotatable in correspondence with one end of the bobbin (12) and comprises a first thread-guide element (14) in which the first inner segment (11a) of yarn passes. The first thread-guide element (14) is supported by a circular element (16) mounted coaxial with the bobbin (12). The circular element (16) is provided with separation means (13) able to separate the first inner segment (11a) from the second outer segment (11b) of the yarn.
