Zusammenfassung:	A system for fabricating muntin bars from sheet material. Sheet materia l in the form of thin ribbon stock is fed to a first forming station including a punching mechanism that punches the ribbon stock at a precisely predetermine d location. The ribbon stock is delivered from the first forming station to a second forming station in the form of a rolling mill. The stock passes through a succession of forming rolls to produce a tube having a desired cross-section al shape. The tube is delivered from the second forming station to a third forming station including a severing apparatus that severs the tube at a precisely predetermined location to produce a muntin bar. After severing, the muntin b ar is engaged by a conveyor and moved to a desired location.
