<p>PURPOSE: To easily and accurately deliver a pellet by warping a free end of a blade oppositely to a nozzle in association with a rotation of a blade holder, giving a force from the blade to a nozzle surface, and cutting the pellet when the blade crosses the nozzle. CONSTITUTION: A hole 34 for receiving a pivot post 35 is formed at a blade holder 30, and a slot 35a for receiving a blade 36 is formed at the post 35. A rotating motion of the blade 36 is limited by a plunger 37 and a spring 38 mounted in a bracket 39 to hold the blade 36 at a stopping surface of the holder 30. Further, the blade 36 is aligned with a nozzle block 40 for extruding a plastic or the like directed toward out of the nozzle 41. When the holder 30 is rotated, a free end 35a of the blade 36 is projected to an arch-like recess of the nozzle 41, and warped in an opposite direction to the rotating direction of the holder 30, and hence a force from the blade 36 to the nozzle surface 41a is given. When the blade 36 crosses the nozzle 41, the extruded pellet is cut.</p> |
