Abstract
According to the invention a flat metal plate for the manufacture of pipe is first oriented generally horizontally on horizontally spaced and longitudinally extending supports. A longitudinally extending center tool is pressed down against the workpiece between the supports so as to downwardly plastically deform the workpiece while simultaneously a brace body is pressed with an upward force against the plate directly opposite the center tool so as to hold the plate in contact with the center tool. The center tool and brace body are then synchronously displaced downward relative to the supports with the plate clamped between the center tool and brace body.
