Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
134 words
A method for joining metal-plastic laminates which comprises: providing two sheet like metal-plastic laminates each of which has a first plastic layer and a second metal layer bonded to one side of the plastic layer, each of said laminates having at least one layered edge portion; removing at least a portion of the plastic from said edge portions of each of said laminates abutting said second metal layer to provide a void in the edge portions of each of said laminates abutting said second metal layer; forming an assembly by placing said edge portions of said laminates adjacent one another with said voids communicating with each other with a rigid strip in said voids overlapping both of said laminates; and securing said strip in each of said voids to provide a firmly joined assembly.
Claim 2
Independent Claim
134 words
A method for joining metal-plastic laminates which comprises: providing two sheet like metal-plastic laminates each of which has a first plastic layer and a second metal layer bonded to one side of the plastic layer, each of said laminates having at least one layered edge portion; removing at least a portion of the plastic from said edge portions of each of said laminates abutting said second metal layer to provide a void in the edge portions of each of said laminates abutting said second metal layer; forming an assembly by placing said edge portions of said laminates adjacent one another with said voids communicating with each other with a rigid strip in said voids overlapping both of said laminates; and securing said strip in each of said voids to provide a firmly joined assembly.
