ABSTRACT:
Drupe pitting apparatus includes means which receive such a fruit, produce a partial cut in its pulp and thus define two fruit halves adhered to the pit of the fruit and grips the pit, and means for gripping the outer surfaces of the two fruit halves. The gripping means includes a pair of opposed gripper heads which are movable toward and away from the fruit halves and each of which has a cavity facing the fruit with an elastic, cup-like diaphragm element extending within and continuously across the gripper head cavity for resiliently engaging and releasingly gripping the fruit half, means for supplying a pressurized operating fluid to the space between the gripper head cavity and the respective diaphragm element dial means for controlling the selective introduction and release of the pressurized fluid within those spaces, and means for rotating the gripping heads in opposite directions about an axis extending through the fruit while the diaphragm elements grip the fruit halves to free the fruit halves from one another and from the pit.
