[Class 82 (ii).] In forming on the surface of a metal sheet, band, strip, &c., a protective or insulating coating consisting of a compound of the metal, e.g. a coating of oxide on aluminium or other oxidizable metal, defects due to irregular coating of the edges are avoided by rounding or retroverting the edges prior to the production of the coating. The edges of a strip a may be bent back to a small extent as at b, Figs. 1 and 3, or so that they meet as at c, Figs. 2 and 4, with or without insertions such as a wire d or strip e which may consist of any desired insulating material such as celluloid, cardboard, paper, yarn, or rubber, or of metal which may have been previously provided with an insulating coating. The edges may be rolled back so as to form a substantially flat spiral. In the form shown in Fig 5 the edges are thickened at g. The protective layer may be formed chemically or electrolytically and the sheets &c. may be used in electric condensers or for constructional purposes, e.g. in the manufacture of airships. The Specification as open to inspection under Sect. 91 (3) (a) describes the treatment in a coating bath of metal strip in the form of a roll to form a protective layer on the edges only, followed by treatment of the unwound strip, the edges thus receiving a double coating. It also describes a method in which the strip is wound helically on a support and then treated to form a protective coating or the strip may first be coated, then wound on the support and again coated. It also describes the rounding off of the edges of a plate by mechanical treatment and the method forming the subject-matter of Specification 365,023. This subject-matter does not appear in the Specification as accepted.
