ABSTRACT:
A method and apparatus for cofeeding additive concentrates in the form of pellets with a polymer flake stream flowing in a supply chute to a melt extruder. The pellets are introduced through an opening in the chute which is covered by an umbrella-like housing that has an opening facing the melt extruder. The flake flows around the umbrella-like housing creating a pocket to provide unimpeded entry of the pellets into the polymer stream.
