Apparatus for applying adhesive to a honeycomb half-cell structure

Abstract

The present invention relates to an apparatus and a process for applying at least one adhesive component to a honeycomb half-cell structure. The half-cell structure has a plurality of peaks and valleys on each side thereof and a diagonal surface between each consecutive peak and valley. The apparatus comprises a first and second back-up roll and a first and second gravure roll. The first and second gravure rolls are disposed in a bath of a first adhesive component and a second adhesive component, respectively. Each of the first and second back-up rolls includes a plurality of spaced bars. The peaks of the half-cell structure face away from the bars of each respective back-up roll, and the peaks on the other side of the half-cell structure contact each respective first and second gravure roll, so that the first adhesive component contacts the peaks on the one side and the second adhesive component contacts the peaks to apply the first and second adhesive components to the half-cell structure.
