The strips can be arranged parallel to a longitudinal axis of the web or at an angle relative thereto. It is also possible to divide the strips into individual blanks at a scrolling station or at a remote can making station. The polygonal shape of the blanks permits them to be designed so as to compensate for earing caused by the anisotropy of the material from which the web is made. Various punches and slitting arrangements can be employed to perforate the web and to longitudinally and laterally cut it so as to form the strip and/or blanks therefrom.
