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.
Claims10
A machine for progressively closing cap strip side flanges on a standing T-rib comprising a base plate, means on the base plate to guide the machine longitudinally of a standing T-rib, power means on the base plate including a rotary eccentric element, a follower engaging the rotary eccentric element and being reciprocated thereby substantially normal to the base plate, a pair of cap strip side flange closing dies disposed below the base plate in laterally spaced relationship, forward and rear suspension arms for the dies pivoted thereto and also being pivotally mounted relative to the base plate for lateral swinging with the dies so that the dies may assume separated inclined positions and side-by-side substantially vertical positions, and said forward suspension arms being coupled to said follower and reciprocated thereby to cause oscillation of the dies about their rear pivoted ends.
