This machine is used in Goodyear production to tighten the cut to the last and fit it to the rib using staples, which the machine itself produces from a roll of wire. The adjustable pincers facilitate the tightening operation, pulling the leather and the lining against the rib while the machine nails the staples. As the wire is very fine this does not complicate make the welt stitching. This machine has been designed to solve the common problems of mechanical machines replacing the brake and the clutch with a variable speed electronic motor.
