Abstract

In order to sort a quantity of hard gelatin capsules of the type having at least a top and bottom and being filled with powdery contents, and to remove therefrom defective capsules which do not have a top or which may be cut or deformed in some way, the apparatus includes a first member with apertures for the capsules and a second member with similar apertures which are aligned with the first apertures in a first relative position of the two members. By applying suction to the top of the second member, intact capsules are urged into the second member while defective or deformed capsules are retained in the calibrated bore of the lower member. The two members undergo a relative displacement subsequent to which a discharge device moves rods into the individual orifice causing the discharge of intact capsules and defective capsules into different receiver chutes.
