Title:
APPARATUS AND METHOD FOR MANUFACTURE OF MULTILAYER METAL PRODUCTS
Document Type and Number:
WIPO Patent Application WO2001053015
Kind Code:
A9
Abstract:
Apparatus and method 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, whereby the multilayer metal assembly is stacked vertically. At the location of making shaped parts from the feedstock material, the layers of the z-fold feedstock material may be separated and one or more of the layers treated, textured, embossed, etc., then reassembled into the stack which is fed to the stamping operation, all on a continuous basis. This enables the z-fold feedstock material to be made from smooth metal layers, which increases the density of the material and reduces the volume space required for storage of the z-fold material.
