Patent number: 7954746Abstract: By the present invention method and apparatus is disclosed whereby a triaxial braided composite reinforcing fabric having axial yarns of varying length may be wrapped about a cylindrical shipping spool without deformation of the braided fabric. A tensioning device is interposed between the braiding tool and shipping or storage spool whereby the individual variable length axial yarns are subjected to constant tensioning. As the braided fabric is wound upon a cylindrical shipping spool, a conformable foam layer is interposed between each layer of braided fabric thereby permitting each axial yarn to seek out its own diameter by compressing the layer of conformable foam upon which it is wrapped.Type: GrantFiled: July 9, 2010Date of Patent: June 7, 2011Assignee: A&P Technology, Inc.Inventors: Andrew A.

Patent number: 7793576Abstract: A machine and method for applying braid by means of a braiding machine to a mandrel, where the mandrel has a shape that approximates a wheel but has an irregularly varying radius of curvature. The machine includes drive/positioning wheel assemblies that are used to continuously reposition a cross-section of the mandrel relative to the braiding machine such that a center point of cross-section of the mandrel is maintained to be coaxial with a braiding point of the braiding machine as the mandrel 18 is rotationally advanced by the drive/positioning wheel assemblies. Repositioning of the drive/positioning wheel assemblies is controlled by a computer numerical control (CNC) controller, based on information describing one or more radiuses of curvature for sections of the mandrel and a current position of the mandrel relative to the drive/positioning wheel assemblies.Type: GrantFiled: January 22, 2008Date of Patent: September 14, 2010Assignee: A&P Technology, Inc.Inventors: Andrew Atkins Head, Brad Goetz, John Peter, Steven Charles Stenard, Thomas C.
