Abstract: A plane with an interchangeable iron that can be displaced at an angle to the contact surface of the plane frame, along the direction in which the plane travels. The iron is also displaceable on each side of a midposition parallel to the contact surface of the plane and transversely with respect to the direction in which the plane travels. The iron is secured in a predetermined position by a support that has a holder against which the iron rests. A support component can be displaced transversely on a frame. The holder is mounted on the support component, so that it can be displaced longitudinally and transversely with respect to the bottom contact surface of the plane.
