ABSTRACT:
Methods and apparatus for applying coating to products such as medicaments are disclosed. The present invention provides a apparatus comprising product holders and plates which interact with vacuum tubes to retain the product being coated in place while inverted and dipped into a tank of coating material. The vacuum tubes may be designed to hold product of nearly any shape or in any orientation. In a preferred embodiment, methods and apparatus for creating a two-color gelatin coating on a tablet are disclosed. In certain embodiments, additional apparatus are provided whereby the vacuum tubes rotate about their longitudinal axes and are placed in contact with a coating applicator, thereby applying a band or stripe of a coating material to a specified section of the product.
