Abstract
Disclosed are a toilet paper roll which is devoid of a cardboard core and has a 2-layer structure comprising a hard core layer portion formed by tightly rolling up a material toilet paper on a temporary take-up core which is eventually removed and an outer layer portion formed continuous to the core layer portion by rolling up the toilet paper less tightly than the core layer portion, over or surrounding the core layer portion, and a method of manufacture of such toilet paper roll.
Claims3
