WEFT INSERTING DEVICE FOR A JET LOOM AND LOOM INCLUDING THE DEVICE

摘要

A weft inserting device has main nozzles (15, 16) supported by a change lever (11) and a cam lever (3) operatively coupled with movable loom parts (1) for reciprocation thereby. Lever (3) can be coupled to change lever (11) by a rod (6) driven by a solenoid (5). The timing of motion transmission and interruption is controlled by a timing control unit (19). According to a preferred embodiment, the control unit (19) is a microcomputer and the timing setting can be changed by changing the weft yarn selection program stored in the microcomputer.
