Abstract

Drive unit for draw benches which is suitable to provide carriages (24) bearing draw grippers (27) with a required, coordinated to-and-fro movement, a radial cam (l3) cooperating with each carriage (24) and pressing on a roller (l4) borne on a first shaft (l5) able to move axially with a first rack (l6) with which a pinion (l7) is engaged that is coaxial with and solidly fixed to a gearing-up gear wheel (l8) acting on a second rack (25) included on the carriage (24), a desired preferred ratio existing between the pinion (l7) and the gear wheel (l8), the pinion (l7) and gear wheel (l8) having an axis which is rotary but not displaceable.
