Continuous fibers are led through a roller nip which is formed between a pair of wetting rollers which are driven in opposite rotational directions and the surface of which has a coating of the flowable plastic material in a thickness which is sufficient for the constant filling of the roller nip with the plastic material. The wetted fibers are fed to the plastic material in the extrusion chamber, and the continuous fibers are mixed with the plastic material in the extrusion chamber. A device for carrying out the method includes a screw-type extruder having an extrusion chamber surrounded by an extruder barrel which has, in addition to the entry opening and the exit opening for the extruded plastic material, a lateral opening for the feeding in of continuous fiber material, and a wetting device for the wetted fiber material to be fed in, the outlet of which is in transporting connection with the lateral opening. |
