Abstract
In a method of electrostatically applying a powder material to a solid dosage form, charged powder material is applied to a photoconductive drum (3), is transferred to an intermediate belt (4) and then to a solid dosage form (5). The belt (4) makes contact with the solid dosage form (5).
Claims32
A method of electrostatically applying a powder material to a solid dosage form, the method comprising the steps of electrostatically applying a powder material to a first intermediate means, and transferring the powder material that has been applied to the first intermediate means from the first intermediate means to the solid dosage form, wherein there is contact between the first intermediate means and the solid dosage form on transfer of the powder material to the solid dosage form.
A method of electrostatically applying a powder material to a solid dosage form, the method comprising the steps of electrostatically applying a powder material to a first intermediate means, and transferring the powder material that has been applied to the first intermediate means from the first intermediate means to the solid dosage form, wherein the powder material that has been applied to the first intermediate means is transferred from the first intermediate means to the solid dosage form via a second intermediate means.
An apparatus for electrostatically applying a powder material to a solid dosage form, the apparatus comprising means for applying a powder material to a first intermediate means, and means for transferring the powder material that has been applied to the first intermediate means from the first intermediate means to the solid dosage form, wherein the first intermediate means is positioned such that there is contact between the first intermediate means and the solid dosage form on transfer of the powder material to the solid dosage form.
An apparatus for electrostatically applying a powder material to a solid dosage form, the apparatus comprising means for applying a powder material to a first intermediate means, and means for transferring the powder material that has been applied to the first intermediate means from the first intermediate means to the solid dosage form, wherein the apparatus further comprises means for transferring the powder material that has been applied to the first intermediate means to a second intermediate means, and means for transferring the powder material that has been transferred to the second intermediate means to the solid dosage form.
