Abstract
Abstract In a rotating paste depositer having an outer rotating cylinder with a plurality of cutouts forming outlets for depositing a fluid or pasty-like material on a comestible product, the outer cylinder rotates around a series of fixed inner cylinders having valves for control of the flow rate of the material to be deposited and having an inner chamber to equalize the pressure at the outlets. In the preferred form a secondary pressure means is contained within the inner chamber and rotates around a fixed cylinder to provide increased pressure at the outlet ports during the depositing cycle and to provide reduced pressure and positive shutoff when the material has been deposited on the product.
