Abstract: A gripper rapier provision for weaving machines with a fixed gripper rapier body has a hook and a gripping face on the inside of the hook. A hinged clip suspended from the fixed gripper rapier body, with a gripping face thereon, works together with the gripping face of the hook to grip a weft thread taken by the gripper rapier provision. A mechanism is provided in front of the extremity of the gap, formed by the gripping face of the hinged clip and the gripping face of the hook, for preventing the weft thread from sliding to the extremity of the gap. It consists of a bar provided on the gripping face of the hook of the gripper rapier body working together with a hole in the hinged clip, or a bar running through the extremity of the hook of the gripper rapier body working together with a hole in the hook of the gripper rapier body, or a bar provided on the hinged clip working together with a hole in the hook of the gripper rapier body.
