PURPOSE:To enable stable supply of raw materials, by providing a partial gearing zone having a specific shape on a partial section of self-wiping complete gearing two-axial screws. CONSTITUTION:The titled extruding machine is so constituted that a partial gearing zone having a constant gearing gap (a) is provided in a partial section of self-wiping complete gearing two-axial screws 1, 1a, as for a shape of the screw of the zone, the number of flights of the same is made fewer than that of the complete gearing zone and as for an imaginary center distance (L-a) obtained by deducting the gearing gap (a) from a center distance L of two axes, gearing becomes self-wiping gearing. As for a partial gearing zone, as the two-axial screws 1, 1a possess a gearing gap (a) always even at any revolving position, raw materials are mixed up complicatedly with each other through the gap (a) according to a rotation of the screw and kneading and plasticization are accelerated effectively. |
