A method of fabricating a duct fitting comprising:
- fabrication of a duct fitting at a work station and automatically inserting angle plates in said duct fitting at said work station, said work station comprising
- (a) an apparatus for automatically assembling an angle plate in channel-shaped flanges at ends of said duct fitting, said apparatus comprising:
- a platen for engaging an end of said duct fitting in a pre-selected position relative to said platen and said platen includes a substantially unobstructed work area adapted to receive said duct fitting;
- clamping members for locking said duct fitting in a pre-selected position relative to said platen;
- a supply hopper for angle plates located underneath said platen for advancing upwardly an angle plate for insertion into said duct fitting;
- an angle plate advancing member for advancing an angle plate into engagement with a corner of said clamped duct fitting;
- and
- pressing members for pressing an angle plate into said corners of said duct fitting;
- and
- (b) a table adjacent said apparatus adapted for use by one or more workers.
