Abstract: Complex shaped articles and a method for their manufacture are disclosed. The complex shaped articles comprise a one piece, honeycomb core material that can be conformally shaped for aerodynamic and hydrodynamic movement having formed edges and an outer skin bonded to its top and bottom surfaces to protect and encase the honeycomb core material and provide a drag resistant surface.

Abstract: The complex shaped articles are formed by trimming, cutting and shaping a honeycomb core material to a desired size and shape, deforming the sized and shaped honeycomb core material at ambient temperature; permanently setting the shape and contour of the sized and shaped honeycomb core material; affixing side edges to the shaped and contoured honeycomb core material; and, bonding a fiber reinforced resin to the top and bottom surfaces of the honeycomb core material.

Abstract: Apparatus for cutting a continuous web into precise length sheets and precisely stacking the sheets, relative to each other, includes first and second moving endless belt tables for advancing the web, a sheet orientation table and a stacking table. A vacuum holds the web firmly, without tension, against the respective belts. A shearing device is disposed between the first and second endless belts. Web, detectors positioned along the line of travel of the web, detect printed or colored lines on the web to obtain accurately cut sheets. Individually driven and positioned sheet grippers grasp the cut sheet positioning each sheet under dual hole punching devices which punch precisely positioned holes in each sheet. A pair of aligning pins on a sheet stacking bed are used as guides for orienting the sheets in interleave configuration. Each sheet is secured to its adjacent sheet to maintain sheet orientation.

Abstract: A cutting apparatus for cutting a web into sheets comprises a web shear. A web stop is disposed downstream of the shear. A web feed is disposed upstream of the web shear. A web stiffening device is disposed between the web shear and the web stop for holding the web in a rigid flat plane whereby the web is repeatedly cut to the same desired length.
