Abstract
A picking mechanism for a loom including a projectile lift which points a projectile into a ready-to-pick position is made with a guide profile cross section open on the striking side. The projectile opener is provided with an additional guide element to guide the projectile body during movement into the ready-to-pick position. After positioning, the projectile opener with the guide element pivots away to expose a semi-circular space on the striking side of the projectile for the operation of a picking mechanism. The opener guide element may engage with an outer surface of the projectile during pivoting or may be positioned coaxially of a gripper opener to engage an internal surface in an additional passage in the projectile.
