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.

[ What is claimed is:] [1.]1. A method of placing an angle plate in channel shaped flanges of a duct, the method comprising:holding the duct via a duct holding mechanism;moving the angle plate into registration with the flanges of the duct as the duct is held via the duct holding mechanism;pressing the angle plate against the flanges of the held duct; andmoving a crimping member along a straight line and into engagement with at least one of the flanges of the duct to crimp said at least one of the flanges in a manner to block removal of the angle plate from said at least one of the flanges.
