Bi-directional seaming machine and method of seaming

摘要

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.

1. A method comprising the steps of:
unwinding a first segment of sheet material from a first roll of sheet material which is wound around a first spool and mounted on a frame adjacent a first end of the frame to position the first segment in a generally horizontal orientation, wherein the first segment of sheet material has first and second opposed edges; unwinding a second segment of sheet material from a second roll of sheet material which is wound around a second spool and mounted on the frame adjacent a second opposed end of the frame to position the second segment over the first segment such that first and second opposed edges of the second segment are respectively adjacent the first and second edges of the first segment; and seaming the first and second sheet segments together along the first edges of the first and second segments to form a two-segment sheet; wherein the first spool is parallel to the second spool.
