Abstract: A strand cutting machine at least includes a rotary blade assembly (A) having a plurality of rotary blades, a stationary blade unit (B) having a guide portion (7) for guiding strands toward the rotary blade in an axial direction of a rotary shaft of the rotary blades and a take up roller (1, 2) disposed on the side of the base end of the guide portion for taking up the strands and further includes a housing for accommodating the above mentioned components. Each rotary blade is comprised of a blade plate (5) having a blade edge at one end thereof. Each blade plate has its blade edge which is the closest to the stationary blade and is located on the same rotary plane and is disposed on and around the rotary shaft while the blade plate is retracted far from the stationary blade in a direction from the blade edge to the base end thereof.

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.
