Manufacture of articles from thermosetting materials

Claim 1

A METHOD OF MANUFACTURING CONTINUOUS LENGTHS OF A HARDENED THERMOSETTING-PLASTIC-IMPREGNATED-FIBER ROD IN A MOLD CAVITY HAVING A LENGTH LESS THAN THAT OF THE ROD, COMPRISING: PROVIDING A MOLD HAVING AN ELONGATED MOLD CAVITY OF A CROSS-SECTIONAL SHAPE OF THE DESIRED CROSSSECTIONAL SHAPE OF THE ROD, SUCH MOLD CAVITY HAVING OPEN ENTRANT AND EXIT ENDS, POSITIONING A LENGTH OF FIBER IMPREGNATED WITH A THERMOSETTING PLASTIC MATERIAL IN SAID CAVITY AND EXTENDING BEYOND BOTH SAID ENDS, THE PLASTIC EXTENDING BEYOND THE EXIT END BEING CURED, THE PLASTIC EXTENDING BEYOND THE ENTRANT END BEING UNCRUED, THE CROSS-SECTIONAL AREA OF THE IMPREGNATED FIBERS EXTENDING BEYOND THE ENTRANT END BEING GREATER THAN THAT OF THE MOLD CAVITY SUCH THAT PORTIONS OF THE PLASTIC WILL BE SCRAPED OR SQUEEZED OFF ONTO THE ENTRANT END OF THE MOLD ADJACENT THE CAVITY AS IMPREGNATED FIBERS ARE PULLED INTO THE MOLD CAVITY, HEATING THE SURFACES OF SAID MOLD CAVITY SPACED FROM THE ENTRANT END THEREOF TO A TEMPERATURE ABOVE THE CURING TEMPERATURE OF SAID PLASTIC IN THE DESIRED TIME CYCLE OF THE MOLDING OPERATION, ALLOWING THE PLASTICIMPREGNATED FIBERS TO REMAIN STATIONARY FOR SUCH TIM CYCLE AND CURING AND THEN PULLING HARDENED PLASTICIMPREGNATED FIBERS FROM THE EXIT END OF THE CAVITY WHILE SIMULTANEOUSLY PULLING IN UNHARDENED PLASTIC-IMPREGNATED FIBER INTO THE ENTRANT END, THE ACT OF PULLING IN THE UNHARDENED PLASTIC INTO THE ENTRANT END SCRAPING AND SQUEEZING OFF UNHARDENED PLASTIC ONTO THE ENTRANT END OF SAID MOLD AND CONTINUOUSLY COOLING THE ENTRANT END OF SAID MOLD TO A TEMPERATURE BELOW THE PARTIAL CURING TEMPERATURE OF THE PLASTIC SO THAT THE SCRAPED OR SQUEEZED OFF PLASTIC DOES NOT CURE AND WILL NOT BE DRAGGED INTO THE MOLD CAVITY.

Claim 2

A METHOD OF MANUFACTURING CONTINUOUS LENGTHS OF A HARDENED THERMOSETTING-PLASTIC-IMPREGNATED-FIBER ROD IN A MOLD CAVITY HAVING A LENGTH LESS THAN THAT OF THE ROD, COMPRISING: PROVIDING A MOLD HAVING AN ELONGATED MOLD CAVITY OF A CROSS-SECTIONAL SHAPE OF THE DESIRED CROSSSECTIONAL SHAPE OF THE ROD, SUCH MOLD CAVITY HAVING OPEN ENTRANT AND EXIT ENDS, POSITIONING A LENGTH OF FIBER IMPREGNATED WITH A THERMOSETTING PLASTIC MATERIAL IN SAID CAVITY AND EXTENDING BEYOND BOTH SAID ENDS, THE PLASTIC EXTENDING BEYOND THE EXIT END BEING CURED, THE PLASTIC EXTENDING BEYOND THE ENTRANT END BEING UNCRUED, THE CROSS-SECTIONAL AREA OF THE IMPREGNATED FIBERS EXTENDING BEYOND THE ENTRANT END BEING GREATER THAN THAT OF THE MOLD CAVITY SUCH THAT PORTIONS OF THE PLASTIC WILL BE SCRAPED OR SQUEEZED OFF ONTO THE ENTRANT END OF THE MOLD ADJACENT THE CAVITY AS IMPREGNATED FIBERS ARE PULLED INTO THE MOLD CAVITY, HEATING THE SURFACES OF SAID MOLD CAVITY SPACED FROM THE ENTRANT END THEREOF TO A TEMPERATURE ABOVE THE CURING TEMPERATURE OF SAID PLASTIC IN THE DESIRED TIME CYCLE OF THE MOLDING OPERATION, ALLOWING THE PLASTICIMPREGNATED FIBERS TO REMAIN STATIONARY FOR SUCH TIM CYCLE AND CURING AND THEN PULLING HARDENED PLASTICIMPREGNATED FIBERS FROM THE EXIT END OF THE CAVITY WHILE SIMULTANEOUSLY PULLING IN UNHARDENED PLASTIC-IMPREGNATED FIBER INTO THE ENTRANT END, THE ACT OF PULLING IN THE UNHARDENED PLASTIC INTO THE ENTRANT END SCRAPING AND SQUEEZING OFF UNHARDENED PLASTIC ONTO THE ENTRANT END OF SAID MOLD AND CONTINUOUSLY COOLING THE ENTRANT END OF SAID MOLD TO A TEMPERATURE BELOW THE PARTIAL CURING TEMPERATURE OF THE PLASTIC SO THAT THE SCRAPED OR SQUEEZED OFF PLASTIC DOES NOT CURE AND WILL NOT BE DRAGGED INTO THE MOLD CAVITY.
