PURPOSE: A strand cutting apparatus is provided for pellets formed by the cutting operation to be prevented from being piled up and for each of the cleaning operation and the maintenance operation not to be complicated. CONSTITUTION: A strand cutting apparatus includes a fixed blade(2) having a blade edge extending perpendicularly with respect to the traveling direction of a strand(S), a rotation blade(3) which is fixed to the tip portion of a rotation shaft(13) disposed in parallel to the traveling direction of the strand(S) and has a plurality of plate-shaped blades disposed radially at a front surface opposing to the fixed blade(2), and a cover(6) for receiving pellets(P) thus cut and exhausting the pellets(P) out of the apparatus. The cover is formed by a lower casing(4) of almost funnel-shape and an upper casing(5) of a semi-cylindrical shape covering the opened portion of the lower casing(4). The center(O1) of the upper casing is made eccentric toward the fixed blade side with respect to the rotation axis(O2) of the rotation blade and so the distance between the inner peripheral surface of the upper casing and a phantom outer peripheral circle(40) of the rotation blade increases gradually toward the rotation direction of the rotation blade and becomes maximum at the side of the fixed blade.
