Process an 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. |

DETAILED DESCRIPTION Thus, the invention is based upon the task of creating a process for the production of a honeycomb core which will supply a honeycomb core of practically any desired dimensions with a very accurate honeycomb height, cheaply, and with the fullest possible utilization of the foil material, i.
e.
with practically no waste, and to propose equipment for carrying out the process in question.
Furthermore, the honeycomb core should enable the continuous production of composite plates.
In accordance with the invention, the task set is solved by a process and equipment as set forth herein.
The present invention comprises a process for the production of an expanded honeycomb core from foil band unrolled from a band coil, which is coated at uniform intervals with strips of adhesive and cut into strips in the direction of uncoiling, the strips then being piled on top of one another with their respective adhesive strips parallel but in staggered positions, and thereafter adhesively bonded together under pressure to form a stack with ends which is finally expanded, characterized in that the foil band is cut into strips whose width corresponds to the honeycomb core height desired; one strip is passed over a position detector which, by detecting the adhesive strips, determines its position relative to the first end of the stack and activates an electronic control unit to control a positioning drive and a cutting device; the positioning drive positions the strip relative to the stack at its end in such a way that the adhesive strips on the strip lie between those of the underlying strip and strip is held fast at the end; beginning from the end, the strip is then progressively bonded to the underlying strip, working towards the direction of the other end; shortly before bonding at the other end, the strip is cut by the cutting device to a preselected length limited by the ends, which corresponds to the desired width of the honeycomb core to be made; the process then repeats itself.
The process of the invention is applied in accordance with the invention for the continuous production of a composite plate with an expanded honeycomb core and at least one covering layer
