Abstract

For bending the edge of a thick sheet of metal a tool comprising a yoke with a long and a short leg with plate-engaging bars in the opening between the legs is used. The tool is placed on a sheet so as to straddle the edge to be bent with one bar on each side of the sheet. An extensible member, for example a hydraulic cylinder, bears against the sheet to tilt the yoke so that the bars are pressed against the sheet to bend it. The tool may be provided with transport wheels and drive equipment for automatically moving the tool on the sheet.
