Window component scrap reduction |
摘要 |
A method of making elongated spacer frame members prevents a first spacer frame member in a series of spacer frame members from being scrapped. A supply of thin relatively narrow sheet metal stock is provided. The stock is fed endwise to a stamping station. The stock is passed through the stamping station that stamps the stock to define a scrap length of stock followed by a connected first spacer frame defining length of stock. The scrap length of stock and the connected first spacer frame defining length of stock are fed to a roll forming station. The scrap length of stock and the connected first spacer frame defining length of stock are formed into a rigid linearly extending scrap element having opposite side walls and a base wall and a connected rigid linearly extending first spacer frame element having opposite side walls and a base wall. A connection between the scrap element and the first spacer frame element is then severed.
