Abstract

The invention provides an apparatus and method for automated manufacture of connective fittings on a duct member, and particularly a tapered adjustable take off. The connective fitting is generally placed near the inlet of the duct member and comprises a seating bead. The connective fitting can also comprise a seating ring groove for use in conjunction with a seating ring for applications involving connection of the duct member through a duct board. The apparatus for forming a connective fitting on the duct member may include a housing including a work station formed therein. A die associated with the work station is selectively positioned at a predetermined location relative to a work piece positioned in association with the work station. A forming assembly associated with the work station cooperates with the die to selectively form a connective fitting in the work piece at a predetermined angle. A positioning system positions the work piece at a predetermined position for forming the connective fitting, and a control system is provided for at least selective control of the forming assembly associated with the work station, or of other characteristics of the apparatus as desired. A method of manufacturing an adjustable duct member may include the steps of providing a duct member comprising a tube of material having predetermined dimensional characteristics, positioning of said duct member in a work station at a predetermined position relative to a forming assembly of said work station, and forming a seating bead in said duct members at a predetermined angle.
