P-323 HYDRAULIC CONTROL CIRCUIT FOR LOADER OF THIN-WALL SPLINE ROLLING MACHINE ABSTRACT OF THE DISCLOSURE A hydraulic control circuit (10) for operating a loader (12) of a machine for splining an annular thin- wall sleeve of a power transmission member is disclosed as including valving (116) for communicating supply and return conduits (102,116) with load and unload cylin- ders (14,16) to provide loading and unloading movements. load and unload valves (118,120) of the valving have load cycle positions where the load cylinder drives both the loading and unloading members (26,28) which clamp a thin-wall member during such movement to pro- vide loading thereof for splining. In an unload cycle position of the valves, both the load and unload cylin- ders are hydraulically driven in an unloading direction opposite to the loading movement. The loading and un- loading members (26,28) are moved away from each other by their associated cylinders in an index cycle of the valves to permit indexing of a load table (30) under the operation of an index valve (162) of the circuit.
