Abstract

Weft thread insertion system into a projectile weaving loom, wherein the projectiles (1) are launched into the shed due to the mechanical action of a thrust member provided with alternate cyclic movement consisting of a rack (R) driven into motion by a plurality of toothed wheels (D), each one controlled by a respective electric servomotor (M), arranged in succession along the rack (R) and meshed therewith.
