High-frequency thread-guide device for the production of bobbins with modulated traversing

摘要

Thread-guide device (18) with modulated traversing with an individual thread-guide (15) having a back-and-forth movement fixed to a flexible element (19), moved between two pulleys (20a,20b) in an alternating clockwise/anticlockwise movement, each driven by its own electric motor (21a,21b), both motors being piloted and coordinated to a control unit.
