An apparatus for creating a florentine finish on a flat metal strip for use in the manufacture of jewelry, comprising,
- a support means adapted to have the flat metal strip positioned thereon,
- means on said support means for longitudinally moving said strip with respect thereto,
- a first power means on said support means, including a horizontally extending power shaft,
- a movable florentining means operatively connected to said first power means which engages one side of said strip to create a uniform-depth florentine finish thereon as said strip is moved on said support means,
- said movable florentining means including a rotatable cutting wheel means on said power shaft which is positioned above the strip and which is in contact therewith, the strip being moved parallel to the longitudinal axis of rotation of said power shaft, and
- means for moving said cutting wheel means back and forth across the strip in a substantially transverse manner with respect to the direction of movement of the strip so as to impart a florentine finish thereon.
