ABSTRACT:
A measuring and transferring device for automatically metering predetermined and variable quantities of virgin plastic material, reprocessed plastic material and color concentrate to an extrusion machine. This masterbatch material blender incorporates a rotary conveyor having openings therein that receive and retain predetermined amounts of virgin plastic material and color concentrate in one position of movement of the conveyor and discharge same to the extruder in yet another position of movement thereof. Furthermore, such conveyor is adapted to control yet another reciprocable metering and transfer mechanism that similarly controls the addition of reprocessed material to the batch by way of the same measuring and transferring device.
