Extrusion apparatus

Claim 1

Apparatus for the extrusion of a flowable mass onto a moving conveyor comprising: a first cylindrical container disposed above the conveyor for rotation about a longitudinal axis, said first container including a plurality of first passages through the container periphery, a second cylindrical container including means for longitudinally admitting into said second container the mass to be extruded and having a wall portion containing a plurality of second passages directed toward the conveyor and radially alignable with said first passages, said wall portion disposed at least closely adjacent said first container, said first container being mounted for continuous 360° rotation about the longitudinal axis thereof relative to said second container such that relative rotation between said containers produces sequential misalignment and alignment of the first and second passages to enable the flowable mass to travel radially outwardly through the aligned passages and onto the conveyor, and a spatula for removing excess mass from the perimeter of said first container, said spatula being directed toward said first container generally in the direction of rotation thereof, said spatula being tightly pressed against the perimeter of said first container in the region of said first passages to scrape excess mass into said first passages.
