Abstract: An apparatus for forming and sealing a duct member for use in an air handling system. At least one work station accommodates a work piece, which is generally a cylindrical tube.

Abstract: An apparatus and method for forming a sealing portion on a duct member for use in connection to another duct member, with the connection between the duct members being substantially sealed from the egress of air in an air handling system.

Abstract: An apparatus for forming and sealing an adjustable duct member for use in an air handling system. At least one work station accommodates a tapered work piece. A repositionable die is positioned relative to the work piece, and a cutting and forming assembly cooperates with the repositionable die to cut the work piece and form a coupling bead to reconnect the members together. A sealing assembly cooperates with the first repositioning die to seal the coupling bead in the first and second members. The work station includes an insertion channel having predetermined dimensions to accommodate at least a portion of the work piece. A clamping assembly is associated with the insertion channel to securely hold the tapered work piece at the predetermined position during the cutting and forming and sealing operations.

Abstract: An apparatus and method for forming a duct member having a plurality of adjustable sections which are rotatable relative to one another. The apparatus and method causes relative rotation between individual sections during the manufacturing process, to form a completed duct member in an automated process utilizing a rotating head assembly comprising a plurality of engagement members extendable radially outward of the rotating head body in an engagement position and retractable radially inward to a disengagement position. Accordingly, a 90 degree adjustable elbow can be produced in its 90 degree elbow configuration without requiring the machine operator to manually adjust the adjustable sections.

Abstract: The invention provides a machine and methods for automated manufacture of tapered adjustable ducts, and particularly tapered adjustable take offs. A tube of material is cut into gores of predetermined configuration, coupling beads are formed in the gores and the gores are adjustably interconnected to one another to form the finished take off duct in an automated fashion. The apparatus for forming an adjustable duct member may include a housing including at least one 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 cutting and forming assembly associated with the work station cooperates with the die to selectively cut the work piece to form first and second members and to form a coupling bead in the first and second members which cooperate to reconnect the first and second members together at a predetermined angle.

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.
