摘要

The machine has an adjustable framework enclosed in cladding and incorporates upper (20) and lower (24) cutting rollers with interdigitating disc segments (21,22;25,26). The discs are interrupted by triangular cutouts (28). The directions of rotation (23,27) are opposed. The positions of the notches are 90 degrees out of phase on adjacent discs on each shaft.
