ABSTRACT:
A rotator is disclosed for precisely rotating a horizontally disposed, cylindrical workpiece comprising first and second workpiece rotator members which are vertically disposed and horizontally spaced-apart. Each of the workpiece rotator members has a gear rack provided at its lower inner end which is in mesh with a driven gear or shaft so that rotation of the shaft in one direction causes the first workpiece rotator member to move upwardly with the second workpiece rotator member being moved downwardly in a corresponding and equal amount. When the driven shaft or gear is moved in a direction opposite to that described, the first workpiece rotator member is moved downwardly while the second workpiece rotator member is moved upwardly. The workpiece is positioned between the workpiece rotator members and precisely rotated in either clockwise or counterclockwise directions so that the proper bends may be imparted to the workpiece after the workpiece has been rotated.
