  • Bi-directional seaming machine and method of seaming
    Patent number: 8826838
    Abstract: A seaming machine and method are provided for seaming segments of sheet material to one another to form larger sheets. The machine typically includes a frame with a pair of spaced seaming devices mounted thereon for respectively seaming opposed edges of the segments of sheet material to one another. The process allows for the seaming of multiple sheet segments while the sheet segments remain atop a work surface. Relative back and forth movement between various components and the work surface typically facilitate the process.
    Type: Grant
    Filed: December 18, 2012
    Date of Patent: September 9, 2014
    Assignee: Miller Weldmaster Corporation
    Inventors: Brian D. Henry, Rodney M. Tunistra

  • Bi-directional seaming machine
    Patent number: 7975633
    Abstract: A seaming machine for seaming segments of sheet material to one another to form larger sheets includes a frame defining a sheet-receiving area and a pair of spaced seaming devices on opposed sides of the sheet-receiving area for respectively seaming opposed edges of the segments of sheet material to one another. The frame typically defines a table-receiving space for a table to support the sheet segments. The machine provides for the seaming of multiple sheet segments while the sheet segments remain atop the table or another work surface. Relative back and forth movement between the frame and work surface facilitate the process.
