A press has a support frame, a fixed traverse, a movable traverse vertically spaced from the fixed traverse, and a guide frame extending from the fixed traverse toward the movable traverse and supporting the movable traverse for vertical movement toward and away from the one traverse. A rigid brace frame has an arm vertically fixed to one of the traverses and another arm. The other of the traverses is between the other arm and the one traverse. One of the frames is fixed to the support frame, and a vertically expansible actuator between the other arm and the other traverse so that the actuator can vertically shift the other traverse toward the one traverse.
