    摘要： THERE IS DISCLOSED A PROCESS FOR REINFORCING EXTRUDED MEMBERS SIMULTANEOUSLY WITH THE EXTRUSION THEREOF WHICH COMPRISES INTRODUCING ELONGATED REINFORCING MEMBERS TO THE MELT CHAMBER OF A CENTRIPETAL EXTRUDER HAVING A MELT CHAMBER AND A ROTATING MEMBER SUCH THAT THE REINFORCING MEMBERS ARE SPIRALLY SWEPT WITH THE SUBSTANCE TO BE EXTRUDED AND ARE ULTIMATELY POSITIONED IN A SPIRAL ARRANGEMENT THROUGH THE EXTRUDED PRODUCT. THE REINFORCING MEMBERS MAY BE INTRODUCED INTO THE MELT CHAMBER VIA THE SAME INLET PASSAGE IMPLOYED FOR FEEDING THE SUBSTANCE TO BE EXTRUDED. ADDITIONALLY OR ALTERNATIVELY, THE REINFORCING MEMBERS MAY BE INTRODUCED INTO THE MELT CHAMBER BY

    ONE OR MORE ADDITIONAL INLET PASSAGES SUITABLY POSITIONED EITHER LATERALLY OR PERIPHERALLY WITH RESPECT TO THE MELT CHAMBER.
