Abstract
Foils are manufactured by creating a pattern on a substrate and then thickening the patterned film. The foil may then be peeled away from the substrate and/or pattern. The patterning step may include use of a laser or use of a photoresist, and may include deposition of a further layer. The thickening step may be performed by electrodeposition or electroless methods. The foils produced may be employed for dry shavers, sieves or filters.
