Beschreibung
Zusammenfassung:	In conventional fabrication manufacture the thickness of the steel plates are often determined by the metal section required at the weld joints. The subject apparatus and method overcomes this problem by selectively forming a thickened edge along the edge of a thinner steel plate which can now be limited to the thickness required to withstand the stresses on the fabrication. The thickened edge is produced by forcing a plate supported by a table, by passing the plate through a forming apparatus comprised of a combination of rollers. The forming apparatus and table are automatically controlled to produce a thickened edge of constant shape along a non-linear edge of the plate.
