Apparatus for inserting a corner member into channel-shaped flanges of a duct. The corner member has first and second legs. The duct includes longitudinally extending duct panels. The channel-shaped flanges of the duct extend laterally from at least one end of the duct panels. The apparatus a corner member support mechanism adapted for supporting the corner member, a duct moving mechanism, and a pressing mechanism. The duct moving mechanism has a duct pusher moveable between a first position and a second position. The duct pusher imparts a moving force against the duct upon movement of the duct pusher from its first position to its second position. The duct moving mechanism moves the duct toward the corner member and to a position in which adjacent flanges of the duct are in registration with the legs of the corner member upon movement of the duct pusher from its first position to its second position when the corner member is being supported by the corner member support mechanism and when the duct pusher is imparting the moving force against the duct. The pressing mechanism has at least one pressing member moveable between a non-pressing position and a pressing position. The pressing mechanism presses the corner member into the duct flanges upon movement of the pressing member from its non-pressing position to its pressing position when the flanges of the duct are in registration with the legs of the corner member.

Apparatus and method for inserting angle plates in channel shaped flanges of a duct

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.
