1. A bag turning machine, comprising: a frame; a shaft rotatably carried by the frame; a plurality of bag turning members carried by the shaft for receiving a filled and sealed bag resting on its side edge and turning the filled and sealed bag onto its face; and a brake for resisting rotation of the shaft upon receipt by the bag turning members of the filled and sealed bag and for arresting rotation of the shaft, following release by the bag turning members of the filled and sealed bag, in a predetermined position for receipt by the bag turning members of another filled and sealed bag; wherein the brake comprises: a cam rotatably carried by the frame and drivingly coupled to the shaft so that resistance to rotation of the cam resists rotation of the shaft; a cam follower movably carried by the frame and arranged to follow an outer perimeter of the cam; and a biasing member acting between the frame and the cam follower to urge the cam follower inwardly against the outer perimeter of the cam; wherein the outer perimeter of the cam has alternating resistance increasing portions and arresting portions.
