ELECTROSTATIC APPLICATION OF POWDER MATERIAL TO SOLID DOSAGE FORMS

摘要

A method of applying coating material onto part of a side of a solid dosage form (100) includes the steps of providing a source of coating material and a support assembly supporting the solid dosage form (100), the support assembly including a shield (101), arranging the solid dosage form (100) relative to the shield (101) with a forward boundary edge of the shield (101) extending around and closely surrounding the side of the solid dosage form (100), and applying coating material to the solid dosage form (100). The boundary edge of the shield has a projecting portion (103) such that the rearward limit of the exposed portion of the side of the solid dosage form (100) curves around the solid dosage form. A solid dosage form produced by the method and an apparatus for carrying out the method are also described.
