A vertical Pittsburgh Seam closing apparatus having a base supporting surface, a track mechanism for moving a carriage assembly which holds seam forming members used to close a Pittsburgh Seam, a pair of upper and lower guide members for guiding the duct section into a proper vertical position, and upper and lower clamping members positioned inside the duct section and adjacent the inside portion of the Pittsburgh Seam to be closed, the upper guide members and clamping member being selectively movable and adjustable for accommodating different duct section lengths. In one embodiment, the seam forming assembly includes a plurality of members mounted in vertical arrangement, at least one of the plurality of seam forming members being shaped to initially bend the overhanging edge portion and at least one of the plurality of seam forming members having a substantially V-shaped configuration for closing the Pittsburgh Seam.

Apparatus for closing pittsburgh seams associated with duct assemblies and other box-shaped members

A vertical Pittsburgh seam closing apparatus having a base supporting surface for positioning a duct section thereon in a vertical orientation, a track mechanism for moving a pair of carriage assemblies each having seam forming members used to close a Pittsburgh seam, a pair of upper and lower guide members for guiding the duct section into a proper position, and upper and lower clamping members movable between an unclamped position and a clamped position wherein each clamping member is positioned inside the duct section and adjacent the inside portion of the Pittsburgh seam to be closed, the upper guide members and clamping member being selectively movable and adjustable for accommodating different duct section lengths. In one embodiment, each seam forming assembly includes a pair of roller members mounted in vertical arrangement to each other, one roller member being V-shaped in configuration and the other roller member being substantially cylindrical in shape.
