Abstract: Apparatus and method for fabricating a rectangular waste disposal container from a single steel sheet, includes a cantilever shaped frame supporting a rectangular mandrel rotatable on a horizontal shaft. A vertically oriented hydraulic ram depends from an arm of the frame and has a tandem roller assembly pivotally mounted at its lower end with an axis parallel to the axis of the mandrel. A steel sheet is fed into the nip between the rollers and the mandrel and the latter is rotated while hydraulic pressure is applied to the rollers to press-break the sheet at the mandrel corners.
