<p>A power weaving loom includes weft thread insertion and collecting bands ( 6, 7 ). Drive units drive the bands and cause leading parts of the bands to move towards and away from one another between sides of the weaving machine and an approximately half-width position ( 13 ) of the machine. The bands include grippers ( 6 b, 7 b), which allow the weft thread to be drawn from a first side of the machine to the approximately half-width position and then to a second side of the machine. The drive units include servomotors which are coordinated to act upon the bands via motion-transmitting members with a torque that allows inward and return motions of the bands during brief shedding times, thus providing high machine picking speeds even in machines of great width.</p> |
