Four pineapples are contour peeled simultaneously fed from a single file elevator conveyor feed system. To accomplish this, the pineapples are picked up from the elevator conveyor, spaced in groups of four and dropped through sliding trap door onto chutes in a group former. The four pineapples are picked up by the pusher fingers of four parallel feeder conveyors and advanced through centering heads. The feeder conveyors then force the four pineapples onto core pins of four core turrets having oppositely projecting core pins.
