Abstract: A design verification method, including (a) providing in a design a design electrically conducting line and a design contact region being in direct physical contact with the design electrically conducting line; (b) modeling a simulated electrically conducting line of the design electrically conducting line; (c) simulating a possible contact region of the design contact region, wherein the design contact region and the possible contact region are not identical; and (d) determining that the design electrically conducting line and the design contact region are potentially defective if an interfacing surface area of the simulated electrically conducting line and the possible contact region is less than a pre-specified value.

Abstract: An apparatus for continuously cutting thin trim strips from a moving printed web so as to form uniform web products and removing the trim strips from the cutting area is provided, for in-line operation with a web press. The gapping of the web is effected by a cutting cylinder with a hollow bore, which carries at least two pairs of spaced cutting knives that act against a stationary shear blade. The space between each pair of blades connects with the cylinder bore, which in turn is connected to a low-pressure source. As a printed web is fed to the cutting cylinder, the spaced knives cut trim strips in the web and these strips are removed through the space and the cylinder bore by air flow caused by the low-pressure source. The circumferential speed of the knives acting on the web is greater than the speed of the web itself, this reducing any bubbling of the web, and the width of the space between knives is greater than the width of the trim strip.
