Method of Making Sandwich-Like Product Starting With Extruded Profile

摘要

A process of making a multi-layered product from an extruded sheet or web of material (42) having parallel upper and lower walls (130) and a plurality of spacers (134) extending between the upper and lower walls (130) is provided. Portions of the extruded web or extrudate (42) are removed in selected areas. The lightened web is then folded. Outer skins are then applied to the folded web. The extrudate (42) is formed into a product (10) having a plurality of cells (14). The cells (14) may have one or more openings (34), allowing access to an interior of the cell (14) and reducing the weight of the product (10).

主权项

1. A process of making a sandwich-like product, said process comprising, in any desired order:
providing an extruded web having spaced upper and lower walls and a plurality of spacers extending between the upper and lower walls, the spacers being spaced from each other to define a plurality of flutes; removing portions of the extruded web using multiple movable tools to create a treated web having lightened areas transversely extending from one side edge of the extruded web to the other side edge of the extruded web; folding the treated web such that upper and lower walls of the untreated regions of the treated web become sidewalls of a plurality of cells arranged in rows of a core of the sandwich-like product; applying outer skins to tops and bottoms of the cells of the core to create a multi-layered web.
