  • Patent number: 3948161
    Abstract: A multi-lane machine for removing the seed cell from previously cored apples by selectively cutting a cavity therein. Various size apples are accommodated and the size of the seed cell cavity is varied depending on the size of the apple. The apples are conveyed along a path while the core hole is oriented relative to the path. Taking advantage of the alignment of the core hole, the apples are transferred onto a spindle and moved therealong by a pair of centering jaws to a seed cell station. The medial plane of the apple is positioned over a seed celling knife on the spindle while the size of the apple is measured as it is moved into the seed celling station. The knife is crescent-shaped and pivotally housed in and rotated by the spindle. A knife control mechanism extends the rotating knife into the seed cell a distance determinate of the size of the apple and in timed sequence with the movement of the jaws. Subsequently, the apple is displaced along the spindle and through a die to cut the apple in segments.
