Abstract: A rotary stamper includes an upper die plate assembly, a lower die plate assembly, and a support frame having a drive assembly that moves the upper die plate horizontally and vertically along a generally circular pathway while moving the lower die plate along a linear horizontal pathway. The upper die plate is vertically slidably connected to the lower die plate by way of one or more vertical rods that extend from the lower die plate assembly up through the upper die plate. In operation, the lower die plate matches the horizontal movements of the upper die plate as the latter is moved along its circular pathway. Concurrently, the upper die plate moves towards and away from the lower die plate. This maintains a substantially constant alignment between the die plates for carrying out a periodic machining operation on a moving web of material passing there between.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A flange for ductwork is integrally formed at a distal end of a duct surface. A first flange portion is formed perpendicularly outward from the duct surface. A second flange portion is bent at a right angle from the first flange portion and substantially parallel to the duct surface. A third flange portion is bent back to be in substantial touching relationship with the second flange portion and towards the first flange portion. A fourth flange portion is bent at a right angle from the third flange portion to be in substantial touching relationship with the first flange portion. Finally, a fifth flange portion is bent at a right angle from the fourth flange portion to be in substantial touching relationship with the duct surface.

Abstract: 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.

Abstract: A spiral pipe machine includes a feeding assembly for continuously feeding a web of material, and a forming assembly for accepting the web. The forming assembly bends the web to form a first section of a spiral pipe having a first predetermined diameter. A controller is employed for selectively instructing the forming means to change its configuration so as to give a second section of the spiral pipe a second predetermined diameter. The controller is capable of controlling the forming station to transition from the first predetermined diameter to the second predetermined diameter during the continuous feeding of the web.
