Plastic forming process and apparatus

Claim 2

A PLASTIC FORMING PROCESS COMPRISING THE STEPS OF PLACING EXTRUDER MEANS WITHIN AN OPEN FEMALE MOLD AND DISPOSING SIMULTANEOUSLY A PLURALITY OF HOT STRANDS OF COHESIVE THERMOPLASTIC MATERIAL SPACEDLY AROUND THE INSIDE SURFACE OF THE OPEN FEMALE MOLD, SAID STRANDS BEING EXTRUDED IN A SUBSTANTIAL ACUTE ANGEL TO THE VERTICAL INTO THE SPACE WITHIN SAID FEMALE MOLD BY A VERTICALLY DISPOSED EXTRUDER EXTENDING INTO SAID SPACE BY WAY OF AN UPPER OPENING IN SAID MOLD, MOVING SAID MOLD TOWARD A MALE DIE TO REMOVE SAID STRANDS FROM THE EXTRUDER AS THE EXTRUDER EXITS FROM THE MOLD BY WAY OF SAID OPENING TO EFFECT THE DISPOSITION OF THE STRANDS AROUND SAID MOLD, CLOSING SAID OPENING, AND CLOSING SAID MOLD WITH THE AID OF THE MALE DIE TO COMPRESS SAID STRANDS INTO A MOLDED ARTICLE.

Claim 3

APPARATUS FOR MOLDING AND WELDING A HEAD TO A TUBULAR BODY TO PRODUCE THERMOPLASTIC CONTAINERS COMPRISING A FEMALE MOLD HAVING AN ACCESS APERTURE AT ITS UPPER END, A MALE DIE VERTICALLY DISPOSED FOR RECEIVING SAID TUBULAR BODY, SAID MOLD BENG VERTICALLY POSITIONED SPACEDLY ABOVE SAID DIE AND MOVABLE DOWNWARDL ONTO THE DIE BY MOVING MEANS, MEANS FOR SPACEDLY DISPOSING HOT STRANDS OF COHESIVE THERMOPLASTIC MATERIAL LONGITUDINALLY ON THE INSIDE SURFACE OF SAID FEMALE MOLD WITH OUTER ENDS OF THE STRANDS BEING OUT OF CONTACT WITH THE MOLD, SAID OUTER ENDS OF SAID STRANDS BEING THE ENDS MOST REMOTE FROM SAID HOT STRAND DISPOSING MEANS, SAID DISPOSING MEANS FURTHER COMPRISING A VERTICALLY DEPENDING NOZZLE HAVING A RING OF DISCRETE ORIFICES AT ITS LOWER END, SAID NOZZLE BEING MOVABLE VERTICALLY THROUGH SAID APERTURE FOR CAUSING SAID STRANDS TO EXUDE AND SEPARATELY HANG FROM SAID ORIFICES IN THE SPACE IN THE MOLD, AND INCLUDING MEANS FOR EFFECTIVELY SEPARATING SAID NOZZLE FROM SAID MOLD THROUGH SAID APERTURE, MEANS FOR DISJOINING SAID STRANDS FROM SAID ORIFICES AS THE NOZZLE AND MOLD SEPARATE, MEANS FOR SUBSTANTIALLY CLOSING SAID ACCESS APERTURE AS THE SAID NOZZLE IS SEPARATED FROM THE MOLD, AND MEANS FOR MOVING SAID DIE AND SAID MODL RELATIVELY TOWARD EACH OTHER TO CAUSE SAID OUTER ENDS OF THE STRANDS TO HEAT SAID TUBULAR BODY AND TO WELD THERETO A HEAD FORMED FROM SAID STRANDS BY THE DIE AND THE MOLD MOVED TOGETHER.

Claim 4

APPARATUS FOR MOLDING AND WELDING A HEAD TO A TUBULAR BODY TO PRODUCE THERMOPLASTIC CONTAINERS COMPRISING A FEMALE MOLD HAVING AN ACCESS APERTURE AT ITS UPPER END, A MALE DIE VERTICALLY DISPOSED FOR RECEIVING SAID TUBULAR BODY, SAID MOLD BENG VERTICALLY POSITIONED SPACEDLY ABOVE SAID DIE AND MOVABLE DOWNWARDL ONTO THE DIE BY MOVING MEANS, MEANS FOR SPACEDLY DISPOSING HOT STRANDS OF COHESIVE THERMOPLASTIC MATERIAL LONGITUDINALLY ON THE INSIDE SURFACE OF SAID FEMALE MOLD WITH OUTER ENDS OF THE STRANDS BEING OUT OF CONTACT WITH THE MOLD, SAID OUTER ENDS OF SAID STRANDS BEING THE ENDS MOST REMOTE FROM SAID HOT STRAND DISPOSING MEANS, SAID DISPOSING MEANS FURTHER COMPRISING A VERTICALLY DEPENDING NOZZLE HAVING A RING OF DISCRETE ORIFICES AT ITS LOWER END, SAID NOZZLE BEING MOVABLE VERTICALLY THROUGH SAID APERTURE FOR CAUSING SAID STRANDS TO EXUDE AND SEPARATELY HANG FROM SAID ORIFICES IN THE SPACE IN THE MOLD, AND INCLUDING MEANS FOR EFFECTIVELY SEPARATING SAID NOZZLE FROM SAID MOLD THROUGH SAID APERTURE, MEANS FOR DISJOINING SAID STRANDS FROM SAID ORIFICES AS THE NOZZLE AND MOLD SEPARATE, MEANS FOR SUBSTANTIALLY CLOSING SAID ACCESS APERTURE AS THE SAID NOZZLE IS SEPARATED FROM THE MOLD, AND MEANS FOR MOVING SAID DIE AND SAID MODL RELATIVELY TOWARD EACH OTHER TO CAUSE SAID OUTER ENDS OF THE STRANDS TO HEAT SAID TUBULAR BODY AND TO WELD THERETO A HEAD FORMED FROM SAID STRANDS BY THE DIE AND THE MOLD MOVED TOGETHER.
