A METHOD FOR PREPARING WEFT SUPPLY TO BE PICKED UPON START OF OPERATION OF A WEAVING LOOM, AND AN APPARATUS FOR EFFECTING THE SAME

摘要

A method for preparing weft supply to be picked upon starting the operation of a weaving loom, the weaving loom comprising a main motor for driving the weaving loom, a crank shaft driven by the main motor, a drum for measuring weft to be picked by a main air jet nozzle, a driving system of the weft measuring drum, and an auxiliary motor for driving the weft measuring drum. The method comprises releasing the normal connection between the driving system of the weft measuring drum and the main motor for driving the weaving loom so as to enable an auxiliary motor to drive the driving system of the weft measuring drum. The weft measuring drum is then positioned by the auxiliary motor at a position suitable for being threaded with the weft. The weft is then threaded onto the weft measuring drum, whereupon the weft measuring drum is driven by the auxiliary motor so as to store a predetermined amount of weft thereon.
