Abstract:
A method for producing a compound from a flowable plastic material and a solid fiber core of reinforcing material, said method comprising:extruding the plastic material from an extrusion chamber, providing a pair of wetting rollers which are driven in opposite rotational directions, said wetting rollers having respective surfaces which form a nip between said rollers, coating said surfaces with a flowable plastic material in a thickness which is sufficient to constantly fill the roller nip with plastic material, feeding continuous fibers of reinforcing material through said nip so that said fibers are wetted with plastic material, feeding the wetted fibers to the plastic material in the extrusion chamber via a lateral opening in the extrusion chamber, and mixing the wetted fibers with the plastic material in the extrusion chamber.
