(57) The object of the present invention is a flanging machine for metal sheet workpieces
having a cylindrical symmetry, of the type including a pair of parallel extending
roller spindles, of which one is placed over the other, the lower spindle being in
a fixed position and the upper spindle being adjustable in height. According to the
invention, the flanging rollers are cylindrycal in shape and the roller and spindle
assembly is pivotally mounted to the machine frame in such a way that the rotation
axis thereof intersects the cylindrical rollers at their tangency points. A driving
means known per se causes the inclination movement of the assembly with respect to
the axis of the cylindrical symmetry workpiece which is rotatably supported on suitable
supports provided of the flanging machine frame.
