Abstract:
A method and apparatus for producing a thin metallic tube having a trailing end portion which optionally can be formed with an external diameter substantially corresponding to or varying from that of the remaining rolled portion of the tube rolled in a three roller skewed rolling mill. This is accomplished by causing an angular unisonal displacement of the roller axes to effect an enlargement of the rolling area, and at least during part of the roller movement, a second movement of the roller perpendicular to the axis of the tube.
