ABSTRACT:
A cylindrical housing and auger drum assembly is mounted to extend from the side of a cubing machine of the type having an annular die assembly, a circular die cavity on the inner periphery of the die assembly, and at least one press wheel that is received in the die cavity. The auger drum carries a rigid blade that forms an auger flight, and which terminates a short distance from the outer end of the drum. A flexible, resilient tip is mounted on the outer end of the rigid blade, and substantially fills the space provided between the auger drum, the housing and the die cavity, the outer edge of the tip being positioned at the die cavity. The tip functions to supply an optimum flow of feed stock to the die cavity, but will flex to allow bypassing when plugging or jamming conditions exist.
