Abstract

Workpiece handling apparatus for use in grinding machines wherein a pair of unground workpieces can be transported from holding or feed apparatus to a respective pair of load positions at the grinding wheel and simultaneously unload a pair of finished or ground workpieces from the load positions and transport the same to discharge apparatus. The handling apparatus include loading apparatus comprising three carriers which simultaneously transport each of a pair of unground workpieces from a respective pickup position at the holding apparatus to a respective one of the pair of load positions and at the same time simultaneously unload each of the pair of finished or ground workpieces from a respective load position and transport the same to the discharge apparatus. The loading apparatus also includes a device for lifting a pair of the ground workpieces from the respective load positions at least slightly away from the grinding wheel over respective substantially rectilinear paths to unload the finished workpieces from the respective load positions prior to transporting the finished workpieces to the discharge apparatus.
