Reclaiming scrap metal in the plumbing industry - where scrap, esp. copper is used as anode for the electroforming of roof gutter components

摘要

This is an addn. to 2924314, which described the recovery of scrap, esp. sheet metal cuttings or worn parts, which are made the anode in an electrolyte, the cathode consisting of a conducting, negative pattern for the electroforming of roof gutter parts. The novelty in the present invention is that the cathode consists of stainless steel, esp. a V2A stainless steel. The cathode may include one or more non-conducting zones, so several separate roof gutter parts can be electroformed simultaneously. The cathode does not require the graphite coating used in the main patent.
