Abstract
A clamp die for urging a tube against a rotatable bend die is mounted for limited translational and rotational motion so that its tube receiving cavity will accommodate and receive a portion of a bend previously made in the tube. Thus, one bend may be started closely adjacent a previous bend and little or no length of the straight and as yet unbent tube need extend forwardly of the point of tangency with the bend die in order to permit gripping by the floating clamp die.
