  "abstract": "A carrier for seam formation and sealing comprising a roller assembly having at least one roller; a housing for holding the roller assembly; a fastening member for mounting the roller to the housing; and the fastening member is an interchangeable mechanism.",
  "claims": [
    "1. A carrier for seam formation and sealing, said carrier comprising: a roller assembly having a first roller and a second roller, the roller assembly configured to deform said seam; a housing for holding said roller assembly; an interchangeable mechanism for mounting said first roller to said housing; and a permanent mechanism for mounting said second roller to said housing, wherein said interchangeable mechanism is operable to selectively alternate an orientation of said first roller between a first position and a second position, said first position being different from said second position.",
    "2. The carrier for seam formation and sealing according to claim 1, wherein: said interchangeable mechanism comprising a spring biased structure.",
    "3. The carrier for seam formation and sealing according to claim 1, wherein: said first roller is half v-shaped.",
    "4. The carrier for seam formation and sealing according to claim 1, wherein said second roller defines a shape which is different from the shape of said first roller.",
    "5. The carrier for seam formation and sealing according to claim 1, wherein: said roller assembly is coated with a release composition.",
    "6. The carrier for seam formation and sealing according to claim 1, wherein said carrier further comprising: a supporting structure having at least one leg.",
    "7. The carrier for seam formation and sealing according to claim 6, wherein: said at least one leg comprising a spring structure.",
    "8. The carrier for seam formation and sealing according to claim 1, wherein: said roller assembly comprising three rollers.",
    "9. The carrier for seam formation and sealing according to claim 1, wherein the permanent mechanism is configured to attach said second roller to said carrier housing such that the second roller cannot be removed without damaging housing or a machine operator is required to use a tool to remove said second roller."

  "description_excerpt": "This invention relates, generally, to a seam sealing system and method, and in particular, to a seam sealing system and method for use with metal duct forming apparatuses.\n\nApparatuses that are able to process a metal blank into one of any number of differing shapes and configurations, via the application of cutting and bending assemblies, are generally well known in the metal formation arts.\n\nOne application of known metal formation apparatuses is in the manufacture of metal ducts, most commonly rectangular metal ducts, from a metal blank. These known metal formation apparatuses typically use rollers and various cutting implements to create the base structure of the duct. Opposing lateral edges of the incomplete duct are shaped into matching seam halves that can be thereafter manipulated and integrated with one another to form a completed and sealed duct.\n\nMetal ducts are commonly formed from different gauges of sheet metal in sections of predetermined length. The sections are then connected to form a continuous duct of desired length for typically used for distributing air or other gasses. Each section of duct is typically formed by bending two pieces of sheet metal of the desired length at a 90° angle. The edges of the piece are joined together forming what is commonly known as a seam. In a “Pittsburgh” type seam one edge of each sheet metal piece is formed with a longitudinally extending groove to form the female portion of the joint while the other edge is bent over along its length to form the male portion of the joint.",
