ABSTRACT:
To retain elongated removable cutter elements (9, 90) on an axially elongated cylindrical body structure (1, 1'), eccentric holding plugs (27, 30, 300) are directly or indirectly engageable with the cutter elements so that the cutter elements can be clamped in grooves (5) with converging side walls, by engaging the eccentric elements either directly against the cutter elements (FIG. 4) or indirectly via a resiliently deflectable or deformable portion (16) of the tool body (1, 1'). The tool body can be formed as an open cage structure (1') (FIGS. 5-8) to permit granulated plastic material to fall between rods or rails (34) formed with the grooves (5) in which the cutter elements (9, 90) are retained by the eccenters (27).
