Abstract:
1. A method of supplying sheet stock to a processing station in a window component production line, comprising: a) supporting a plurality of rotatable sheet stock coils of different width sheet stock on a moveable carriage; b) selecting a desired coil from the plurality of rotatable sheet stock coils; c) automatically indexing the desired coil to an uncoiling position by moving the carriage so that an end portion defined by a fixed stock edge of the sheet stock from the desired coil is aligned for subsequent movement for entrance to a processing station; d) moving an adjustable guide toward or away from a fixed guide so that the sheet stock from the desired coil passes between the fixed guide and the adjustable guide to accommodate different widths of said sheet stock, the adjustable and fixed guides being located on the moveable carriage; and e) automatically uncoiling sheet stock from the desired sheet stock coil that has been indexed to the uncoiling position to thereby provide sheet stock to a downstream processing station.
