Abstract:
1. A method of making multiple elongated spacer frame members for supporting spaced apart glass panes in a window or door that prevents a first spacer frame member in a series of spacer frame members from being scrapped, comprising: a) providing a supply of thin relatively narrow sheet metal stock; b) feeding the stock endwise to a stamping station; c) passing the stock through the stamping station that stamps the stock to define a scrap length of stock followed by multiple connected spacer frame defining lengths of stock; d) feeding the scrap length of stock and the connected spacer frame defining lengths of stock to a roll forming station; e) forming the scrap length of stock and a connected first spacer frame defining length of stock into a rigid linearly extending generally channel shaped scrap element having opposite side walls and a base wall connected to a rigid linearly extending generally channel shaped first spacer frame element having opposite side walls for supporting spaced apart glass panes and a base wall; and f) severing a connection between the scrap element and the first spacer frame element and discarding the scrap element.
