Abstract

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.

Abstract

A coil processor is provided for performing processing operations on coiled sheet-like material, such as sheet metal, plastics or other materials. The coil processor uncoils and straightens the material before performing desired operations on the material and transferring it for packaging, shipping or further processing. Various features improve the overall efficiency of the coil processor, including its ability to move material forward and backward through the unit without slowing down the overall operation, as well as the versatility of its mobile tool carriers, which can perform multiple complex processing applications, including cutting, punching, stamping, bending or others. Additionally, processing efficiency may be further enhanced by the use of a computer, which determines the most efficient sequence for performing processing operations, and controls the coil processor's various features to process material in that sequence.

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.

• F16L 23/00 - Flanged joints

Abstract

A flange-forming apparatus allows a user to automatically adjust the device's roll forming stations, concurrently together, for changing the height of a flange formed into a metal web by the roll forming stations, e.g., for ductwork. The height is adjustable within an infinite range between set maximum and minimum limits. Each roll forming station includes upper and lower roll forming pairs, which cooperate for forming the flange or portion thereof. Each roll forming pair includes a first roll forming portion, and a second, coaxial roll forming portion that is axially moveable towards and away from the first roll forming portion. (The portions are in effect a laterally split roll forming die.) The second roll forming portions are rotatably supported on a plate-like adjustment linkage assembly, which can be shifted, using an array of motor driven screw members, towards or away from the first roll forming portions.

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 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.

• B21C 45/00 - Separating mandrels from work or vice versa

Abstract

A formation and rotation apparatus (100) for use in forming and rotating interconnected sections of a cylindrical workpiece, including a frame (102) and a head (106) arranged within the frame, the head defining two slots (114) and being operatively rotated via an integral drive assembly. A first slide block (110) is slidably disposed within one of the two slots, and a second slide block (112) is disposed within another of the two slots, each of the first and the second slide blocks include a cutting wheel (116) and a beading wheel (118) for successively forming each of the interconnected sections. An armature (46) having an axis of rotation is also provided, along with a gripping mechanism (32) being operatively connected to the armature. A drive mechanism selectively rotates the armature about the axis of rotation after the gripping means has dosed about one of the interconnected sections.
