Abstract (en)

[origin: US4597277A] Metal sheets of aluminum are provided with raised reinforcing portions of substantial height by rolling. The rolls have recesses or channels (6) whose side faces are in a counter-taper configuration with respect to a plane perpendicular to the axis of the cylinder, with an angle of inclination ( alpha ) of up to 5 DEG . The resulting product may advantageously be used for producing perforated metal sheets with high modulus of inertia.
