Seam closing apparatus

摘要

A seam closing apparatus for use in sealing a duct seam having an outwardly extending sealing portion and a lower fold includes a handle portion having a power actuation trigger and a first roller for engaging the outwardly extending sealing portion of the duct seam. A second roller is also provided for engaging the lower fold of the duct seam. Operation of the power actuation trigger causes the first roller to rotate in a first direction, thereby flattening the outwardly extending sealing portion of the duct seam.
