摘要

A method for preparing weft supply to be picked upon start of operation of a weaving loom, the weaving loom comprising a main motor (11) for driving the weaving loom, a crank shaft (13) driven by the main motor (11), a drum (28) for measuring weft to be picked by a main air jet nozzle (49), a driving system (20, 27) of the weft measuring drum (28), and an auxiliary motor (36) for driving the weft measuring drum (28), the method comprises:
releasing connection between the driving system (20, 27) of the weft measuring drum (28) and the main motor (11) for driving the weaving loom so as to enable the auxiliary motor (36) to drive the driving system (20, 27) of the weft measuring drum (28);positioning the weft measuring drum (28) by means of the auxiliary motor (36) at a position suitable for being threaded with the weft;threading the weft onto the weft measuring drum (28); anddriving the weft measuring drum (28) by the auxiliary motor (36) so as to store a predetermined amount of weft thereon.
