ABSTRACT:
In the method, binding tape is fed through a puller assembly in a flat orientation from a source, such as a binding reel assembly. The binding tape is received by a folder assembly via the puller assembly and is folded so as to change orientation of the binding tape from a flat orientation to an orientation that wraps around the edge of the material product. The re-oriented tape is stitched to the material product edge with thread, and for any remaining loose binding or thread, a sealer assembly simultaneously binds the binding tape and thread so as to produce a finished edge. The sealer assembly may include a heated blade that simultaneously cuts and thermally fuses the binding tape to the thread.
