Abstract
The disclosure concerns a continuous mixer for plastic material and of the type which permits control of the pressure on the material being mixed in the mixer by resisting the flow of mixed material displaced from the mixer when unmixed material is fed into the mixer. The resistance to the discharged flow is effected by one or more elements which engage the flow and which are movable.
