Abstract

A screw extruder having a barrel with a longitudinal bore for receiving a rotatable screw, a transverse bore disposed in the barrel tangential to the longitudinal bore for receiving and supporting a pin wherein the pin extends partially into the longitudinal bore. The tangential arrangement of the pin substantially decreases the susceptability of the pin to bending or breaking. The pin may also be adjustably positioned in the transverse bore and further may be subject to thermal heating and cooling.
