ABSTRACT:
A cutter assembly of a strand cutting machine comprises a fixed cutter member, over which the strand is to be drawn after being cooled and dewatered, and a rotary cutter member coactive with said fixed cutter member to cut a strand of resin into pellets. The rotary cutter member includes i) a cylindrical rotary body having a forward side surface parallel to a supply-side end surface of the fixed cutter member, ii) a rotary shaft extending perpendicularly to the supply-side end surface of the fixed cutter member and supporting thereon the rotary body, and iii) a plurality of blades mounted on the rotary body in a forward inclined posture in the direction of rotation. The rotary body has a plurality of through-holes arranged at regular distances along a circle concentric with the rotary body, each through-hole extending between opposite surfaces. Each blade is attached to an inside surface 5a of the respective through-hole and has at its end a cutting edge.
