An apparatus for moving the gripper of an inserter for workpieces in a machine tool has a rotor with an endless first cam in its peripheral surface and a second cam in one of its end faces. A carriage which is reciprocable in parallelism with the axis of the rotor receives motion from the first cam by way of a reciprocable toothed rack, a gear segment which is turnable by the rack, and a lever which is coupled to a slide on the carriage. The latter mounts a place-like support for the gripper in such a way that the support is movable at right angles to the direction of reciprocation of the carriage. The support receives motion from the second cam by way of a turnable guide member for the carriage and a lever which extends into a groove of the support. The support moves transversely of the direction of reciprocation of the carriage when the rotor is driven by a motor. Each revolution of the rotor entails a back-and-forth movement of the carriage with the support and a back-and-forth movement of the support relative to the carriage.
