Profiled cross-section three dimensional woven fabric

A profiled cross-section three-dimensional woven fabric having a plurality of mutually intersecting longitudinal, transverse and vertical filaments woven in longitudinal, transverse and vertical planes,

• said transverse planes being of differing width and said vertical planes being of differing height within a cross-section of said woven fabric perpendicular to said longitudinal woven filament planes,
• a woven filament in said transverse filament planes moving from one transverse plane to the next transverse plane after reciprocating transversely the longitudinal filaments in the width of the longitudinal plane traversed,
• a woven filament in said vertical woven filament planes moving from one vertical plane to the next vertical plane after reciprocating vertically the longitudinal filaments in the height of the vertical plane traversed, said transversely woven filament and said vertically woven filament clamping said longitudinal filaments, uniting all of said woven filaments together into a profiled cross-section three-dimensional woven fabric,
• said fabric being characterized in that grooves are formed in surfaces of said woven fabric in portions wherein single filaments are included in transverse planes between longitudinal filaments in said longitudinal planes and between adjacent filaments in said vertical planes, the fabric having at least a portion wherein such grooves are eliminated by inclusion of an even number of transverse filaments in each transverse plane of such portion between longitudinal filaments in longitudinal planes of said portion and transversely between adjacent vertical filaments in said vertical planes, and at least one of said filaments is included in a loop formed by adjacent vertical filaments above the longitudinal filaments in the uppermost longitudinal plane and below the longitudinal filaments in the lowermost longitudinal plane.
