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.
