Abstract: A capsule inspection machine has a horizontal ring with vertical openings having a minimum diameter equal to a predetermined maximum capsule cap diameter for the reception of individual capsules and a motor to rotate this ring. A capsule feeding device feeds capsules to a sorting wheel having plates perpendicular to the axis of the wheel and spaced apart a distance greater than the diameter of the capsule body and slightly less than the diameter of a capsule cap to pass through uncapped bodies and carry capped bodies with caps having the desired minimum diameter. A second motor rotates the wheel on a horizontal axis to advance capped bodies and discharge them onto the ring and into the ring openings.
