Abstract:
A strand cutting apparatus comprising:a take-up roller formed by a pair of upper and lower rollers for taking up and sending a strand on a fixed blade, said fixed blade having a blade edge extending perpendicularly with respect to a traveling direction of said strand:a disc-shaped rotation blade having a rotation shaft disposed in parallel to said traveling direction of said strand and having a plurality of plate-shaped blades disposed radially at a front surface opposing to said blade edge of said fixed blade; anda cover for receiving pellets sequentially formed by cutting said strand by said fixed blade and said rotation blade and for exhausting said pellets out of said apparatus, said cover is defined by a lower casing of substantially funnel-shaped having an opened portion at an upper surface thereof and an upper casing of a semi-cylindrical shape covering said opened portion of said lower casing,wherein a center of said upper casing is made eccentric toward said fixed blade side with respect to a rotation axis of said rotation blade so that a distance between an inner peripheral surface of said upper casing and a phantom outer peripheral circle drawn in accordance with a rotation of said rotation blade increases gradually toward the rotation direction of said rotation blade and becomes maximum at a side of said fixed blade,wherein said upper roller of said take-up roller is disposed on said upper casing.
