Abstract
Pharmaceutical tablets and the like articles are coated with coating material which is sprayed onto a selected part or parts of a bed of the articles. Drying air or gas is passed through a further part or parts of the bed while the selected part or parts of the bed have little or no drying air or gas passed through them. Articles are continuously transferred between the selected part or parts of the bed and the further part or parts of the bed until all the articles are coated.
