Improved coated medicaments and apparatus and methods of making the same are disclosed. Most preferably, products are coated at each end with gelatin or other coatings. The present invention discloses products having unequal coatings, as well as coatings applied to each end of a product which may or may not overlap, or leave a portion of the product uncoated. The apparatus disclosed comprises a hopper for retaining a plurality of the product in a predetermined orientation, and a feeder which fills a plurality of plate means retaining a plurality of the product. The product is most preferably retained in a pair of axially aligned specimens within a collet. The plates are incrementally advanced to a first dipping means and coated with a first coating material. After dipping, at least one of the plates is preferably rotated one and one-half times. The plate is then advanced to a second dipping means. A second rotating means places the plate back in its initial orientation, preferably after one and one-half revolutions. The plates are then transferred by the apparatus to dryer means for curing the first and second coatings. After extraction from the dryer, coated product is ejected from the plates. Methods of coating medicaments are also disclosed.
