A core intended to support a reel of paper, particularly toilet paper, is formed by winding at least one web of cellulose wadding. The core is formed by winding at least one web of cellulose wadding having at least 0.51 g of water-soluble material per gram of cellulose wadding, the water-soluble material being designed to make the web of cellulose wadding more rigid and easier to disintegrate. Thus configured, the core that has both mechanical strength fit for the intended purpose and is far easier to disintegrate than a core mad of cardboard such that it can be disposed of directly in a toilet bowl without the risk of blocking the waste pipe.

Core forming support of a paper reel

A coreless roll of an absorbent sheet product, such as napkins, toilet paper, towels etc., including a spirally wound continuous web of absorbent material having a first end and a second end and a coating composition comprising a specific polymer coated onto the second end is disclosed. The coreless roll has excellent resistance to collapsing, as well as excellent flexibility and elasticity. Moreover, the coreless roll has excellent disintegrability in water and can be used along its whole length. Also disclosed is a process for the manufacture of the coreless roll.

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.
