ABSTRACT:
In a shuttleless weaving machine wherein the filling yarn is inserted into the shed from both sides by gripper systems provided with clamping devices and advanced into and then retracted from the shed, the filling yarn is transferred by a controlled opening and closing of the clamping devices from one gripper system to the other. An articulated link drive including a second rocker arm pivotally supported at a fixed point in the machine is provided for this purpose. The articulated link drive is driven by a cam and cam follower on a first rocker arm connected to the link drive by a coupling link. One link of the articulated link drive has an extension which controls the clamping devices in the shed. The dimensions of the articulated link drive are such that the coupling curve described by the control extension during the time of the reed beat-up leads to a non-interfering rest position underneath the path of the batten or sley. All parts of the control drive are located outside the batten or sley and are not tilted together with the sley during reed beat-up.
