ABSTRACT:
A self-propelled roof T-rib cap flange closing or seaming machine has a base with guidance means to travel along the top of the cap strip. Cap strip closing dies on opposite sides of the machine having crowned tops and angled flange engaging leading faces are oscillated vertically about their rearward ends by drive motor and eccentric cam means on the machine. The crowned tops of the dies react against the formed flanges of the cap strip to advance the machine longitudinally of the standing rib for progressively closing said flanges.
