ABSTRACT:
The present invention provides a device for assembling tools on a wheel. Stop pins fixed to the wheel cooperate with radial wedges to maintain tool-bearing sectors in a disc formation on the wheel. The pins and the radial wedges are located between adjacent sectors alternatively, with one wedge being positioned between two adjacent faces or ends of adjacent sectors to urge the other ends of the sectors into engagement with two of the pins.
