Abstract: A system for transferring supports for objects which can be stacked and unstacked between a conveyor and a machine for printing the objects, characterized in that it includes: a mobile transfer table which has two locations each adapted to receive an object support and which is adapted to occupy a plurality of positions, first drive elements adapted to drive the transfer table vertically up and down, and second drive elements adapted to advance or withdraw the transfer table horizontally and simultaneously to transfer a support containing objects and an empty support or to withdraw the empty transfer table to a position awaiting a new support.

Abstract: An automatic camshaft lathe having a plurality of machining tools mounted on tool slides fed and oriented by cam-actuated mechanical transmissions and located to simultaneously machine a plurality of cam surfaces on camshafts mounted at two machining stations in the lathe. The two machining stations are arranged symmetrically relative to the longitudinal vertical centerplane of the lathe. A single shaft mounted above the respective machining stations supports and drives the feed and orienting cams for the tool slides at each machining station. A common gear train drives the shafts operating the control cams for each machining station.
