Abstract
A continuous extruder for thermosetting resins comprising two screws received in a cylinder so as to rotate in opposite directions. Each of these screws is successively divided into a feed portion, a rotor portion and a discharge portion from the end of the cylinder where one or more material supply orifices are located. The cylinder is opened at the opposite end so as to mount a die. The outside of the cylinder is surrounded by jackets for controlling temperature.
