1. THE METHOD OF MAKING FILAMENT-WOUND PRESSURE VESSELS COMPRISING: (1) SUPPORTING A WINDING FORM (A) FOR ROTATION ON A FIRST AXIS THROUGH THE FORM BETWEEN TWO OPPOSITE END PORTIONS OF THE FORM, AND (B) FOR REVOLUTION ON A SECOND AXIS TRANSVERSE TO SAID FIRST AXIS, AND (C) SO THAT THE ANGLE BETWEEN SAID AXES IS ADJUSTABLY VARIABLE; (2) MAINTAINING A CONTINUOUS LENGTH OF FILAMENTARY MATERIAL TRAINED TO THE FORM FOR FEEDING TOWARD THE FORM, (A) THAT PORTION OF THE FILAMENTARY MATERIAL ADJOINING THE FORM BEING MAINTAINED IN A FIXED WINDING PLANE WHICH IS NORMAL TO SAID SECOND AXIS; (3) ORIENTING SAID FORM RELATIVE TO SAID WINDING PLANE SO THAT SAID WINDING PLANE INTERSECTS PRESELECTED REGIONS OF SAID END PORTIONS OF THE FORM AND ALSO INTERSECTS SAID FIRST AXIS BETWEEN SAID END PORTIONS; (4) CONTINUOUSLY REVOLVING SAID WINDING FORM ON SAID SECOND AXIS SO THAT THE FILAMENTARY MATERIAL IN SAID WINDING PLANE IS WRAPPED PROGRESSIVELY IN LOOPS LENGTHWISE OF THE WINDING FORM AND WHICH LOOPS EXTEND ACROSS SAID PRESELECTED REGIONS AND SAID END PORTIONS AND ALONG THE SHORTEST PATH BETWEEN SAID END PORTIONS; (5) INTERMITTENTLY ROTATNG THE FORM ON SAID FIRST AXIS THROUGH A SMALL ANGLE DURING SAID REVOLUTION, SAID INTERMITTEN ROTATION OCCURING DURING ONLY THAT PORTION OF A REVOLUTION ON SAID SECOND AXIS WHEN EACH END PORTION OF THE FORM IS PRESENTED TO THE FILAMENTARY MATERIAL IN SAID WINDING PLANE, (A) SAID ANGLE BEING OF SUCH SIZE AS TO INDEX THE SURFACE OF THE FORM RELATIVE TO SAID WINDING PLANE A DISTANCE NOT EXCEEDING THE LATERAL WIDTH OF THE FILAMENTARY MATERIAL, (6) ENCAPSULATING SAID FILAMENTARY MATERIAL IN A MOLDING RESIN AS SAID MATERIAL FEEDS TOWARD THE WINDING FORM AS A RESULT OF SAID REVOLUTION AND ROTATION OF THE FORM; (7) STOPPING SAID REVOLUTION AND INTERMITTEN ROTATION OF THE FORM AFTER THE WINDING FORM IS ENCLOSED BY A SERIES OF SAID LENGTHWISE LOOPS OF SAID FILAMENTARY MATERIAL; (8) TRAINING A CONTINUOUS LENGTH OF RESIN-COVERED FILAMENTARY MATERIAL FOR FEEDING TOWARD THE FORM IN A DIRECTION SUBSTANTIALLY PREPENDICULAR TO SAID FIRST AXIS, (9) THEN ROTATING SAID FORM CONTINUOUSLY ON SAID FIRST AXIS WHILE HOLDING SAID FORM STATIONARY ON SAID SECONDARY AXIS TO WRAP SAID FILAMENTARY MATERIAL IN A SERIES OF LOOPS ENCIRCLING SAID FORM SUBSTANTIALLY PERPENDICULAR TO SAID FRIST AXIS AND OVERLYING SAID LENGTHWISE LOOPS FROM ONE END PORTION OF THE FORM TO THE OTHER END PORTION, AND (10) THEN TREATING THE RESULTING COMPOSITE WINDINGS TO SET SAID RESIN INTO A HARD MATRIX CONTAINING SAID FILAMENTARY MATERIAL.
