  • Transfer head for holding half-cell structure
    Patent number: 5616204
    Abstract: The present invention relates to an apparatus and a process for a half-cell structure to make a hexagonal-cell honeycomb core. The structure has a plurality of peaks and valleys and a diagonal surface between each consecutive peak and valley. The apparatus comprises a stack holder for stacking the structure so that as one sheet is placed on top of a stack comprising at least one sheet, the peaks of one sheet contact the peaks of an adjacent sheet. The apparatus also comprises an air blower disposed beneath the top of the stack for reducing the air pressure surrounding the stack to a pressure below the air pressure on the top of the stack, thereby pressing the layers together to form the core. The present invention also relates to a transfer head and a process for holding a half-cell structure.

  • Apparatus and process for forming a wad of yarn
    Patent number: 4956901
    Abstract: A layered yarn package is formed of continuous filament yarn wads wherein the yarn alternates between compacted an extended lengths by axially compacting the yarn into a length, segmenting the length into alternating extended and compacted lengths then arranging the compacted lengths in a common axial direction one next to the other to form a layer. The layer may be compressed. One or more layers may form the package.
