Apparatus for the production of a honeycomb core from foil strip

Abstract

Process and equipment for the production of an expanded honeycomb core from strips (10) coated at uniform intervals with strips of adhesive (6), in which the strips (10) with their adhesive strips (6) parallel and in staggered positions are stacked on top of one another and adhesively bonded together under pressure and if necessary at an elevated temperature, the stack (40) so formed being subsequently expanded, consists in the following: a strip (10) passes over a position detector (24), which from the adhesive strips (6) determines its position relative to a first end (P) of a stack (40), and which controls a positioning drive (25) and a cutting device (26). The positioning drive (25) positions the strip (10) relative to the stack (40) at its end (P), and the strip (10) is held fast. Beginning from end (P), the strip (10) is progressively bonded in the direction of the other end (Q) to the previously stacked and underlying strip (10') in such a way that the adhesive strips (6) on strip (10) lie in-between those on the underlying strip (10'). Shortly before being bonded at the other end (Q), the strip (10) is cut by the cutting device (26) to a predetermined length limited by the ends (P. Q), which determines the desired width of the honeycomb core to be produced. The process is then repeated.
