Abstract
Apparatus for removing a first angle plate from a stack of angle plates and inserting the first angle plate in channel shaped flanges of a duct. The first angle plate is the bottom-most angle plate of the stack before it is removed from the stack. The stack includes a second angle plate which is the next to bottom-most angle plate of the stack before the first angle plate is removed from the stack. The apparatus comprises a duct holding mechanism configured for holding the duct in a fixed position, a separating mechanism, and a plate advancing mechanism. The separating mechanism has at least one support member engageable with the second angle plate in a manner for supporting the second angle plate. The separating mechanism is configured and operable for vertically separating the first and second angle plates from one another. The plate advancing mechanism has a plate engageable member moveable between first and second positions and engageable with the first angle plate after vertical separation of the first and second angle plates for advancing the first angle plate into registration with the flanges of the duct.
