A harvester header including a plurality of stripper devices for separating a corn ear or a seed head from a stalk. Each stripper device comprises a left deck plate, a right deck plate, a stalk puller, and at least two crop conveyors. The stalk puller is adapted to separate the corn ear or seed head from the stalk when the corn ear or seed head engages the left and right deck plates. Each of the crop conveyors of each stripper device is arranged between two adjacent stripper devices. The crop conveyors comprise a movable closed transport surface for conveying the separated corn ears or seed heads by moving the closed transport surface in a direction of conveyance which is parallel to the closed transport surface. The transport surfaces of the crop conveyors are arranged at a level below blocking surfaces of the deck plates adjacent to the crop conveyors.
