Abstract:
1. A process of making a sandwich-like product comprising: extruding a web of material having a generally non-planar profile comprising continuous corrugations with continuous flattened peaks and flattened valleys joined by connecting portions extending in the direction of travel of the web; interrupting the continuous corrugations of the extruded web using movable tools on opposite sides of the extruded web to create non-perforated transversely extending rectangular flats to create a plastically deformed web; folding the plastically deformed web along transversely extending fold lines along the edges of the flats to create a honeycomb core comprising a plurality of cells arranged in rows, each of the cells having a top and a bottom, the top and bottom each being in the shape of a polygon; applying generally planar outer skins to the tops and bottoms of the cells of the honeycomb core to create a multi-layered web; and cutting the multi-layered web.
