    Patent number: 5121635
    Abstract: An apparatus for handling an object such as fruit having a major axis, includes at least one roller and a drive unit. The roller frictionally engages the object. The drive unit rotates the roller at a speed sufficient to cause the major axis of the object to be reoriented in a predetermined direction. This facilitates measuring the size and density of objects in a consistent manner.
