Abstract
Pastilles are formed by passing small quantities of a viscous material through small openings and onto a moving conveyor surface located therebeneath. The viscous material is contacted by the conveyor surface after the material protrudes from the openings, but before the material becomes sufficiently large to break free and fall. Instead, the conveyor surface forcefully extracts the material from the openings, thereby resulting in the formation of pastilles which are of smaller size than would have been the case had the material been allowed to break free and fall on its own accord.
