Abstract
A method for making a water-degradable paper sheet involves the following: providing at least one strip of a water-soluble binding material in the form of a dry film; providing at least two strips each made of at least one ply of cellulose wadding; placing the strip of water-soluble binding material between the two strips of cellulose wadding; humidifying, assembling and pressing the three strips; and drying the complex strip thus obtained. The sheet thus obtained can be used for making a roll carrier mandrel by helically winding one or more strips from the sheet about a cylinder. Articles produced from the sheet can particularly be used in the field of products for sanitary or domestic use.
