Abstract (en)
[origin: EP3415671A1] Improved system for gripping/releasing the weft threads in a projectile weaving loom, wherein each of the projectiles (P) comprises, housed therein, a gripping lever (1) and a releasing lever (3) pivoted to the body of the projectile (P) and movable between a weft thread gripping position, a weft thread clamping position and a weft thread releasing position. The rotation movement of the gripping lever (1) and of the releasing lever (3), against the action of thrust means (M), is caused by the contact between a portion (lps, 8) of said gripping and releasing levers (1, 3) and respective fixed slides (S1, S2) arranged along a portion of the projectile guide track (P), before the inlet and after the outlet of the shed.
