A gripper head for looms working with removal of the filling thread from stationary bobbins comprises a clamping gap formed by a fixed stop and a movable clamping tongue. The clamping gap serves to fixedly clamp a filling thread which passes through the clamping gap essentially perpendicular to the central plane of the warp threads. The clamping tongue is structured to be displaceable in the lengthwise direction of the gripper head for opening and closing the clamping gap. Due to this actuation of the clamping tongue, by displacement thereof in horizontal direction, the clamping tongue is insensitive to flutter movements of the gripper head caused by vertical oscillations and there is ensured for more positive clamping of the filling thread.
