Strand cutting apparatus

摘要

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 6 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 02 of the rotation blade 3 and so the distance between the inner peripheral surface of the upper casing 5 and a phantom outer peripheral circle 40 of the rotation blade 3 increases gradually toward the rotation direction of the rotation blade 3 and becomes maximum at the side of the fixed blade 2. <IMAGE>
