An adjustable cam arrangement is provided for controlling various work handling elements of a multistage press. Releasable cam disc members are mounted on a camshaft for actuating a respective cam follower associated with a work handling element. The cam disc members are drivingly coupled to the camshaft in response to a supply of fluid pressure. The cam disc members contain a pair of cam discs adjustable by a motor for independently rotating the cam discs relative to the camshaft for varying the duration and timing of work handling elements.
