In a pellet cutting apparatus in which one or more rotatable blades are adapted to cut plastic strands extruded through a cutting surface of a perforated die plate including:
- a housing support mounting the die plate for extrusion of material through said plate;
- a unit adjustably secured to said housing and mounting the blades for rotation along said cutting surface;
- means for aligning the plane of rotation of the blades with said cutting surface comprising an adjustable ring arranged between the housing and said unit, said ring having a wedge-like cross section forming a locating surface complementary to a mating surface on one of said unit and said support;
- and
- means for adjusting said ring relative to said support and said unit in directions generally parallel to said cutting surface thereby varying the angular relation of the support and the unit for aligning the plane of rotation of the blades with said cutting surface, said adjustment means comprising several set screws in registration with said ring and said support to permit manual regulation and adjustment thereof.
