A method for applying a braided fabric over a mandrel using a braiding apparatus having a central axis and providing braiding yarns drawn toward a braiding point where a braid is formed on the mandrel, the method comprising the steps of advancing the mandrel through the braiding point of the braiding apparatus, determining a current position of the mandrel; and controlling the position of the mandrel transversely to the central axis of the braiding apparatus responsive to the current position such that a center point of a mandrel cross-section passing through the braiding apparatus is coincident with the braiding point.

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 mandrelis 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.

A braiding apparatus and method of forming braided product. The braiding apparatus may have one or more former rings having an adjustable inner diameters. The former rings may have a plurality of elements at least radially movable so that the inner diameter may be adjusted. The former ring may also include means to actuate the elements to adjust the inner diameter. The braided product made by the braiding apparatus may be multi-layered without a winding between layers.

A method of producing a generally tubular, reinforced, structure including an inner layer of braided material having a predefined indentation configuration, the method including the steps of providing a mandrel having a shape and configuration of indentations corresponding to the shape and indentation configuration of the inner layer, providing a plurality of support members in the vicinity of at least some of the indentations on the mandrel, the support members protruding a predetermined distance radially outwardly from the mandrel, depositing the inner layer over the mandrel and the support members, and removing the support members to a position in which the support members do not protrude the surface of the mandrel.

Integrally-reinforced braided tubular structure and method of producing the same

A method and device for forming composites using a pre-consolidated tubular braid (i.e., a braid removed from the braiding machine on which it was produced prior to use in further processing) including feeding the pre-consolidated tubular braid over a supporting mandrel, impregnating the braid with a resin using a pressurized resin injection chamber with a mandrel adapted to provide adequate impregnation, feeding the resin saturated braid into a pultrusion die with a mandrel for forming and heating and pulling the cured composite from the die for finishing the end product.

A rotary heating apparatus, for example, for liquefying glass batch or the like, is provided with dynamic stability by isolating structural support elements from vessel elements that are subject to thermal distortion and by supporting the vessel so as to be self-centering. The preferred embodiment entails a support ring separate from the vessel, rotatably supported at an elevation above the center of gravity of the vessel, and attached to a lower portion of the vessel by way of a plurality of link rods. Horizontal force is applied to the support ring to damp oscillations of the vessel. Rotation of the ring may be on a conical track to aid self-centering.

In a surgical stapler having a driver and an anvil for forming a staple in tissue, a four-bar linkage is driven by a drive cam which is at least partially curved. The curved cam provides, with the linkage, an increasing mechanical advantage for reducing forces required to operate the stapler and to form a staple. The drive minimizes the range of forces required to operate the stapler throughout an operating cycle. Cam and linkage relationships are disclosed.
