Abstract
A method of producing rolls of ribbons including printing indica at a plurality of locations on at least one of two webs; applying peelable adhesive at a plurality of locations on at least one of the two webs; bonding the two webs together using the adhesive where the indicia and the adhesive are registered with each other; die cutting only one of the webs after bonding to form a plurality of peelable lid shapes, having lift tabs for each peelable lid shape, on the other web; die cutting the other non-cut web to form a plurality of parallel ribbons of interconnected lid shapes with each one of the interconnected lid shapes associated with one of the peelable lid shapes; bending the lift tabs onto their respective peelable lid shape; and winding each of the ribbons into a roll on a central core.
