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. The transfer head comprises a plurality of support bars for supporting the half-cell structure and at least one space formed between each support bar, where the width of each space is about the distance between adjacent valleys of the structure, and the depth of the space is greater than the height of the peaks.
