ABSTRACT:
A feeding screw assembly of a molding machine for plasticizable masses, particularly, plastics and rubber, comprises a passage part of the screw which has a passage therethrough having mixing means therein for intermixing a plasticizable material which passes through the passage. The material is diverted into the mixing passage which extends completely through the length of the mixing part by communicating passages located upstream for the inflow of the material and downstream for the discharge of the material after it is mixed. The construction may also include a passage portion which comprises an annular displaceable part having an end or side bounding a communicating passage upstream and which will move in a direction to close off this passage after a part of the other material has been fed into the mixing passage.
