ABSTRACT:
An extrusion apparatus for the production of mixtures of molten synthetic material includes a gear pump which is provided in the flow of molten material. The gear pump comprises a housing and two meshing gear pump wheels. The line joining the centers of the two wheels extends at right angles to the central longitudinal axis of the hollow cylinder. Outlet and inlet openings are formed in the cylinder of the extrusion apparatus which lead directly into the gear pump housing into regions which are, respectively, upstream and downstream of the gear wheels. The major surfaces of the gear wheels are disposed horizontally relative to the central longitudinal axis of the hollow cylinder.
