Abstract:
1. A method of changing elongated spacer frame widths in an elongated spacer frame production line, comprising: a) automatically indexing a first sheet stock coil with a first width to an uncoiling position; b) providing sheet stock having the first width to a stamping station having multiple dies for stamping sheet stock to form a series of interconnected spacer frames; c) stamping the sheet stock having the first width at the stamping station until a last spacer frame in the series of interconnected spacer frames has been stamped; d) severing the last spacer frame from sheet stock having the first width and retracting the sheet stock having the first width from the stamping station onto the first sheet stock coil; e) automatically indexing a second sheet stock coil with sheet stock having a second width to the uncoiling position while the sheet stock having the first width is being further processed by a subsequent processing station downstream from the stamping station; f) automatically adjusting the stamping station for stamping of the sheet stock having the second width; g) providing sheet stock having the second width to the stamping station for stamping a second series of interconnected spacer frames; and h) processing the sheet stock having the second width at the subsequent processing station downstream from the stamping station.
