flanging-machine

Century Dictionary and Cyclopedia

1. n. A machine for bending the edges of boiler-iron, ship-plates, or sheet-metal to form a curved or bent edge or flange. For pipes and hollow ware such machines are made in the form of a revolving mechanism which presses the edge of the tube or vessel against an anvil, or of a wheel which traverses the edge of the vessel, bending the edge back as it advances. In other forms, as in the flanging-press, the edge of a flat plate is bent by direct pressure in a hydraulic press.
