A METHOD FOR WEAVING DEEP PILE CONTOURED INFLATABLE FABRIC WHICH INCLUDES THE STEPS OF WEAVING TWO FABRICS OF WARP AND WEFT YARNS IN SUBSTANTIALLY PARALLEL AND SPACED RELATIONSHIP, TAKING THE FABRICS AWAY FROM THE WEAVING EDGE IN SUBSTANTIALLY STRAIGHT AND PARALLEL SPACED RELATIONSHIP, WEAVING A PLURALITY OF DROP YARNS LONGITUDINALLY INTO THE FABRICS IN SUBSTANTIALLY PARALLEL RELATIONSHIP TO THE WARP YARNS, CROSSING SAID DROP YARNS OVER FROM ONE FABRIC TO THE OTHER, EXTENDING THE CROSSED OVER DROP YARNS PRE-DETERMINED DISTANCES TO ACHIEVE A DESIRED SPACED RELATIONSHIP BETWEEN THE FABRICS WHEN THE FABRICS ARE MOVED APART AFTER THE WEAVING IS COMPLETED, WHERE SUCH EXTENSION IS INDEPENDENT OF ANY OTHER WEAVING OPERATION AND WHERE THE EXTENSIONS OF INDIVIDUAL DROP YARNS ARE VARIABLE ACROSS THE WIDTH OF THE FABRICS, AND SUBSEQUENTLY WEAVING THE EXTENDED AND CROSSED OVER DROP YARNS INTO THEIR RESPECTIVE FABRICS TO HOLD THE DROP YARNS IN POSITION BEFORE THE NEXT CROSS OVER THEREOF.
