Abstract: Apparatus for manufacturing multi-layer metal feedstock material for stamping shaped parts eliminates the need for rolls of metal at the stamping site. Multilayer metal feedstock material is assembled from multiple rolls of metal stock, then folded in a zig zag fashion, or “Z-fold” configuration, whereby the multilayer metal assembly is stacked vertically, usually on conventional pallets, for ease of moving with a forklift or otherwise. The multilayer metal z-fold stack of material is then transported to a parts stamping operation where the material is used as it unfolds as a continuous feed to machines to produce shaped multilayer metal parts. This invention is most useful in making multilayer metal foil z-fold feedstock material and using the z-fold material as continuous feed to processes for making shaped multilayer metal foil parts. The layers may have non-metal layers of material, such as fiber, between the metal layers or on the outside of the metal layers.

Abstract: A composite reinforced plastic lumber article, having a generally rectangular cross-section, is formed by extruding a wood particle/polymer composition through an extrusion die which forms a corrugated or relatively thin sheet cross-section core part. The core part is compressed to push corrugations closer together and then cooled in a two-stage cooling process with water spray and submersion followed by vacuum and air blast drying of the article, followed by extruding an outer coating of the same composition over the core part. A continuous plank-like composite article is thus formed and is cooled after the outer coating is extruded over the core part. Opposed surfaces of the article may be embossed to provide a woodgrain appearance. The two-stage article forming process provides rapid cooling of the material to enhance the speed of production of reinforced plastic lumber articles.

Abstract: A completely vented upholstered body of grid plates with a wave profile includes solid portions of the grid which pass through the wave extrema of its wave contour. Many of the solid portions of the grid preferably are disposed transversely to at least one wave propagation direction and, in each case, continuously over a large portion of a wavelength, at a distance from one another. There is only a limited, specified bending deformation, during which the solid portions of the grid can be deformed largely independently of one another as if they were individual spiral springs. As a result, the upholstered body has a high point elasticity despite the plate construction. By adroit dimensioning of the course of the wave thickness, an advantageous diffusion of stresses can be achieved without stress peaks. Moreover, the work of deformation is absorbed uniformly in the upholstered material. This results in a long service life of the upholstered body.
