An apparatus for applying a circumferential discontinuous coated region on a surface of a tablet-shaped substrate, comprising:
- a fixture, wherein said fixture contains movable pins, wherein said movable pins engage features on opposing surfaces of said tablet-shaped substrate;
- a movable surface in close proximity to said fixture;
- and
- a means for applying coating solution to said movable surface;
- wherein rotation of said movable surface induces rotation and subsequent circumferential application of said coating solution to said tablet-shaped substrate.
An apparatus for applying a circumferential discontinuous coated region on a surface of a caplet-shaped substrate, comprising:
- a fixture, wherein said fixture contains one or more drive rings;
- a movable surface in close proximity to said fixture;
- and
- a solution bath for applying coating solution to said movable surface;
- wherein rotation of said movable surface induces rotation and subsequent circumferential application of said coating solution to said caplet-shaped substrate;
- and
- wherein said one or more drive rings disrupt a boundry fluid layer to assist rotation of said caplet-shaped substrate.
An apparatus for applying a circumferential discontinuous coated region on a surface of a non-rounded horizontally caplet-shaped substrate, comprising:
- a fixture;
- a movable surface in close proximity to said fixture;
- a moving abutment face;
- and
- a solution bath for applying coating solution to said movable surface;
- wherein rotation of said movable surface induces rotation and subsequent circumferential application of said coating solution to said non-rounded horizontally caplet-shaped substrate;
- and
- wherein said moving abutment face runs along the movable surface prior to said fixture to assist with rolling of said non-rounded horizontally caplet-shaped substrate.
An apparatus for applying one or more discontinuous coated regions on a surface of a substrate, comprising an applicator, wherein an end face of said applicator comprises openings such that when said applicator comprises fluid, air can escape from said openings, and wherein a surface area of said end face of said applicator and spacing of said openings are selected to control a volume of coating material passing across said end face of said applicator.
