Abstract
A method of converting, on an in-line printing press, two webs of material into a roll including a web and a plurality of peelable lids thereon. Alternatively, a plurality of underlying lids can be formed from the other web of the roll, in registration with the peelable lids, where these lids are created by die cutting the two webs while bonded. Also, one of the lids has dispensing holes and the other lid is printed with selected indicia and/or logos.
