The apples enter at the right and move to the left until they pass between the helix coils. good and, unlike the slat device, size was based on the largest dimension of the fruit. The rotation of the rollers caused the Mcintosh fruit to rotate with the core parallel to the axis of the roller, and the incline of the rollers caused translation so that size was based on transverse dimension of the fruit. The helical sizing device had several defects. Fruit wedging was the most serious fault. This might be expected from results of the slat sizer tests, since these devices operate on the same gen- eral principle—the helical having a circular rather than linear tapered opening. Like the slat device, it sized Mcintosh fruits by the small dimension. The magnitude of sizing error was the largest of all devices tested. Its potential capacity is very limited, even if the sizer diameter were increased to 24 inches, which is possible. Multiple units could be used, but this would complicate the intro- duction of the fruit into the submersion tank. The square-link chain sizer was repeatedly ac-
