<p>PURPOSE:To always accurately obtain a pellet having a predetermined shape by providing a control means increasing and decreasing the granulation speed of a pelletizer corresponding to the increase and decrease of the supply amt. of a supply mechanism. CONSTITUTION:When the amt. of the molten resin A supplied to a hopper 6 changes and the level in the hopper 6 changes, this change is detected by a sensor 17 and a control signal is sent to a supply mechanism 3 and a pelletizer 2 from a control box 18. That is, when the level in the hopper 6 lowers, the rotational speed of the motor 15 of a supply mechanism 3 is lowered to reduce the supply amt. of the resin to return the resin level in the hopper 6 to a predetermined amt. At the same time, the rotational speed of the motor 16 of the pelletizer 2 is lowered to alter a granulation speed in proportion to the reduction of the supply amt. When the resin level is raised, the reverse operation is performed.</p> |
