| 20090162597 | Multi-Ply Disintegratable Absorbent Sheet, Associated Roll and Associated Manufacturing Process - The invention relates to a substantially rectangular multi-ply disintegratable absorbent sheet based on tissue which comprises at least three plies, and which has a coefficient K | 06-25-2009 |
| 20100006247 | Method And Installation For The Combination Of Plies Forming An Absorbent Sheet - The present invention relates to a method for the combination of at least two plies ( | 01-14-2010 |
| 20100009125 | Method And Assembly For The Manufacture Of An Absorbent Sheet, and Absorbent Sheet Obtained - The invention relates to a process for manufacturing an absorbent sheet comprising at least two plies of cellulose wadding, consisting in combining said plies under pressure by passing between two steel cylindrical components, the first being smooth on the outside and the second being equipped with raised components on the outside and the hardness of the first cylindrical component being lower than that of the second cylindrical component. According to the invention, the first cylindrical component has a treated hardened surface layer and a deformable underlayer; the second cylindrical component has a hardened outer surface, and the sheet, when it passes between the two cylindrical components is compressed at a specific pressure between 40 and 250 N/mm | 01-14-2010 |
| 20100151174 | ABSORBENT COMPOSITE SHEET, ROLL OF SUCH A SHEET, PACKET OF SHEETS, AND MANUFACTURING PROCESS - An absorbent composite sheet for domestic use includes a first ply of paper, with a degree of absorption of liquids equal to or greater than around 5 (g/g CEN standard), and a second superposed ply composed of a metal-containing layer, the thickness of the second ply being equal to or less than around 10 microns (μm). | 06-17-2010 |
| 20100167889 | CORE INTENDED TO BE USED AS A SUPPORT FOR A ROLL OF PAPER - A core intended to be used as a support for a roll of paper, especially toilet paper, is formed by winding at least one strip made of tissue, the strip being impregnated, at least locally, with starch so as to improve its stiffness. Thus configured, a core is provided having both a mechanical strength suitable for the envisaged use and a greatly improved ability to disintegrate relative to a cardboard core so as to allow it to be able to be disposed of directly in a toilet bowl without risk of blocking the soil pipe. | 07-01-2010 |
| 20110278388 | CORE FORMING SUPPORT OF A PAPER REEL - 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 made of cardboard such that it can be disposed of directly in a toilet bowl without the risk of blocking the waste pipe. | 11-17-2011 |
| 20110290423 | Method And Assembly For The Manufacture Of An Absorbent Sheet, and Absorbent Sheet Obtained - The invention relates to a process for manufacturing an absorbent sheet comprising at least two plies of cellulose wadding, consisting in combining said plies under pressure by passing between two steel cylindrical components, the first being smooth on the outside and the second being equipped with raised components on the outside and the hardness of the first cylindrical component being lower than that of the second cylindrical component. According to the invention, the first cylindrical component has a treated hardened surface layer and a deformable underlayer; the second cylindrical component has a hardened outer surface, and the sheet, when it passes between the two cylindrical components is compressed at a specific pressure between 40 and 250 N/mm | 12-01-2011 |
| 20110305855 | WATER-DEGRADABLE PAPER SHEET, AND TUBE FOR A PAPER ROLL CONSISTING OF SUCH A SHEET - A water-degradable paper sheet has a basis weight of 80 to 400 g/m | 12-15-2011 |
