A device for removing thimbles from the bottom ends of reprocessed anode bars. At least one externally toothed hollow shaft (12, 13) with a clamp ring is rotatably supported in a housing (10). Upon the hollow shaft being raised, a clamping ring engages a thimble. The external teeth of the hollow shaft are engaged by the teeth of a gear rack component of a double acting hydraulic piston whereby the thimble is twisted off the end of the anode bar.
