Abstract: Methods and machine for manufacturing vertically oriented core of multiwalls and multiwalls comprising such core. Multiwalls or cores of multiwalls with transversely oriented flutes in their core are sliced perpendicularly relative to the axis of rotation of the flutes. The slices are bent relative to the origin multiwall or core, packed together, welded or fused or mechanically pressed to each other and their top and bottom surfaces leveled to provide a vertically oriented shortened flutes that form the core. The top and bottom surfaces of the core are then laminated. Machine configurations are also provided for continuous manufacturing of vertically oriented cores of multiwalls.

Abstract: Modular constructions made of easily assembled and disassembled light-weight materials, where the structural parts of these constructions are made of multiwall sheets that enclose a supporting structure. The supporting structure may be a plurality of bubbles, corrugated or fluted structure that respond anisotropically to pressure applied towards a bendable surface of the two surfaces along a desired line of bending. The second surface opposite the bendable surface is textured allowing printing graphics on it that is not stretched or harmed in the bending area, thereby enabling continuous flow of graphics along the entire printing area. The line of bending may be formed thermally, mechanically or in a combination of thermal and mechanic operations. The sheets are folded upon themselves to form three-dimensional structures. These structures combine together to form modular constructions such as shelf systems, cabinets, closets, vanities and cupboards.

Abstract: A circularly folding display stand that includes a plurality of sector-like partitioned, that can be compressed into storage mode by folding the partitions together to minimize sector area, and can be opened into a display mode by opening the partitions to maximize sector area.

Abstract: A folding apparatus for storing articles for display, the apparatus including a board of multiwall structure of polypropylene material which board includes two parallel vertical folds dividing a first sheet of the board into a back-plane part, a left side part and a right side part. The side parts are foldable by 180 degrees with respect to the back-plane part. The back-plane part includes a plurality of horizontal slots, and the side parts include a plurality of holes corresponding to the plurality of slots. The apparatus also includes a A plurality of rods which are insertable through corresponding holes in the side parts. The apparatus also includes a plurality of shelves also including multiwall structure of polypropylene material, where each shelf rests on one of the plurality of rods and has a flap inserted in a corresponding slot.
