Förfarande för lösgöring av galvaniskt framställda plåtar från moderpl åtarna

摘要

This specification describes the mechanical separation of galvanically-formed metal sheets from a master by subjecting a composite, consisting of a master sheet and a formed sheet on each side of said master, to the action of multiple rolls disposed in non-aligned relation on both sides of said composite so as to cause said composite to bend in at least one direction without any substantial decrease in the cross-section thereof. This controlled bending causes the formed sheets to readily separate from the master sheet without manual mechanical manipulation. It is stated that slight elastic deformation of the master upon bending is sometimes desirable.
