| 20100310347 | FORMATION AND ROTATIONAL APPARATUS AND METHOD FOR CYLINDRICAL WORKPIECES - A formation and rotation apparatus for use in forming and rotating interconnected sections of a cylindrical workpiece, including a frame and a head arranged within the frame, the head defining two slots and being operatively rotated via an integral drive assembly. A first slide block is slidably disposed within one of the two slots, and a second slide block is disposed within another of the two slots, each of the first and the second slide blocks include a cutting wheel and a beading wheel for successively forming each of the interconnected sections. An armature having an axis of rotation is also provided, along with a gripping mechanism being operatively connected to the armature. A drive mechanism selectively rotates the armature about the axis of rotation after the gripping means has closed about one of the interconnected sections. | 12-09-2010 |
| 20100229376 | APPARATUS FOR ASSEMBLING INSULATED DUCT SECTIONS - A ductmaking apparatus forms a laminate section including a sheet metal layer and a layer of insulation fastened to the sheet metal layer. The layer of insulation is severed from a moving web of insulation by pivoting slicing movement of a knife across the moving web. | 09-16-2010 |
| 20100170318 | ELBOW FORMATION APPARATUS - An apparatus for forming and rotating interconnected sections of a cylindrical sheet metal workpiece to provide an elbow. The apparatus includes a frame, a head rotatably arranged within the frame and a tool ring mounted to the frame, the head and tool ring being co-operable for sectioning and joining segments of the workpiece. The apparatus also includes a drive drum mounted within the frame for gripping and rotating the segments, and a control module for selectively activating the head, the ring, and the drive drum to form an elbow. | 07-08-2010 |
| 20100077822 | DUCT BLANK SEAM AND APPARATUS FOR MAKING A DUCT BLANK SEAM - A flanged duct blank has a male part defined by lead notches formed at each side of a leading end and has a female part defined by trail notches formed at each side of a trailing end. The male part includes a lock tab. The female part includes a leg part and a Z-bend. The Z-bend includes a leg part and a gap. The duct blank is repeatedly clamped and bent by a pivoting wiper to form a duct portion. The pivoting wiper includes a clench tool that has a retractable rib and a retractable roller. With the lock tab inserted into the Z-bend and the retractable rib engaged with the Z-bend, the retractable roller clenches the leg part over the lock tab to lock the male and female parts together in a duct seam. | 04-01-2010 |
| 20100077821 | DUCT MAKING APPARATUS AND METHOD - A duct making apparatus bends a metal web to form a duct blank having a lock tab at a forward end and having a Z-fold at a rearward end. Prior to shearing off the duct blank from the metal web, the apparatus bends the duct blank to insert the lock tab into the Z-fold, and further bends the Z-fold to form a clinch tab holding the lock tab into the Z-fold. After shearing off the duct blank from the metal web, the apparatus clinches the clinch tab over the lock tab to form a completed duct blank. | 04-01-2010 |
| 20090084152 | DUCTMAKING APPARATUS - A ductmaking apparatus bends a metal web to form a duct blank having a lock seam with male and female portions. Prior to shearing off the duct blank, the apparatus bends the web to form a lock tab that secures the lock seam during subsequent handling of the duct blank. | 04-02-2009 |
