Abstract
A method of manufacturing packaged curved edge cigarette rolling papers including stacking a cigarette rolling paper blanks to form a leaf stack. The leaf stack is enclosed within a folded cover to form a covered leaf stack. A band is wrapped around the covered leaf stack to hold the leaf stack in alignment with the cover while the cover and leaf stack is die cut to form packaged curved edge cigarette rolling papers. The curved edge is continuous arc, for example an elliptical arc which eliminates the corners that can interfere with cigarette hand rolling.
