<p>A gear drive for a shuttleless loom is equipped with a coupling device or clutch between an input first gear group (G1) and an output second gear group (G2). The coupling or clutch provides a form-locking connection between the two gear groups which convert a continuous rotational movement on the input side into a back-and-forth movement on the output side to drive, for example, a gripper rod for the insertion of the weft thread into the loom shed. The coupling device or clutch can be rapidly operated by an electromagnet or by an electric motor and greatly facilitates performing the operations that are, for example, necessary for repairing a broken weft thread.</p> |
