Definitions

  • one feature of the invention resides in an apparatus which comprises a rotatable roller having a periphery and a plurality of stationary gap-forming elements arranged angularly spaced about the periphery and defining with the same respective wedge-shaped gaps which taper in direction of rotation of the roller.
  • Feed means is provided for feeding material to be plastified into a first one of the gaps for successive movement of such material through all the gaps in response to rotation of the roller.
  • FIG. 5 is a fragmentary view analogous to FIG. 4 butt illustrating a further possibile adjusting means for ad justing the gap width;
