Abstract

In the manufacture of a battery separator (see Group XXXVI), an extruded ribbon of plastic material is passed between an upper roll having coarsely pitched, circumferential grooves and a lower roll having finely pitched helical grooves so as to form coarsely pitched longitudinal ribs on one side of the ribbon and finely pitched inclined ribs on the other.
