Abstract
The present invention relates to a foldable honeycomb structure and method for making the same. The method comprises (a) providing a plurality of flat strips; (b) forming a pair of longitudinal creases in each strip thereby defining the first two longitudinal margins of each strip and a central portion of each strip between the creases; (c) folding each strip along said creases so that each folded strip has two exposed outside surfaces; (d) applying at least three longitudinal glue lines to the exposed outside surface of each folded strip; and (e) stacking the glued strips. As a result, it need not open the longitudinal margins during the process of applying the longitudinal glue lines, which can avoid the deformation of the strip and have a precise gluing position.
