ABSTRACT:
In an apparatus for spin-forming a drop-center wheel rim which includes axially reciprocable head and tail stock sections, a centrifugally actuated clamp is mounted on the tail stock section and is adapted to engage an internal groove in the head stock section as the sections are conjointly rotated to prevent axial movement therebetween during the high-speed spin-forming operation.
