ABSTRACT:
Apparatus for the extrusion of a flowable mass onto a conveyor, comprises first and second cylindrical containers. The first container is disposed for rotation about a longitudinal axis and includes first passages for depositing the flowable mass. The second container includes a wall portion which contains a plurality of second passages. The wall portion is disposed against the first container, the latter rotating relative to the second container so that the first and second passages are periodically aligned to enable the flowable mass to be deposited onto the conveyor. The first and second containers define a gap therebetween which creates a negative pressure to suck-in excess mass from the outer periphery of the apparatus. A spatula is provided to push the mass into the gap.
