Publication number: 20070122595Abstract: This invention relates to a sheet comprising at least a first ply P1 and a second ply P2 superimposed on one another and made of absorbent paper, such as tissue paper, each ply having a grammage of between 10 and 40 g/m2, the first ply presenting on its outer side cavities formed by embossing, corresponding to protuberances on its other side adjacent to the second ply. The sheet is characterized in that the first ply P1 comprises first zones A1 forming cells with first cavities (12), the cells being surrounded by second zones A2 with second cavities (18), the first zones A1 being in relief on the outer side in relation to the second zones A2 with a level difference NA, the first zones A1 presenting a contour D with a marking line. The invention also relates to the embossing device permitting such a sheet product to be obtained. The product of the invention is applicable to the manufacture of paper for sanitary or household use.Type: ApplicationFiled: October 1, 2004Publication date: May 31, 2007Applicant: Georgia-Pacific FranceInventors: Michel Basler, Benoit Hoeft, Sebastien Jeannot

Patent number: 6942755Abstract: The invention relates to a method for manufacturing a sheet of paper tissue which is embossed by an embossing cylinder of which the surface is fitted at least in part with embossing elements. The elements include a frustoconical base portion and a tip portion. The method is characterized in that the tip segment includes a flat of which the area is less than 75% of the smaller cross-sectional area of the base. Preferably the area of the flat is less than 20% of the base cross-sectional area. The invention furthermore concerns a sheet thusly manufactured and to sheets made of several plies of which at least one is a ply of the invention.Type: GrantFiled: June 26, 2002Date of Patent: September 13, 2005Assignee: Georgia-Pacific FranceInventors: Michel Basler, Pierre Graff, Benoît Hoeft, Sébastien Jeannot

Publication number: 20040231813Abstract: The invention relates to an absorbent paper product, made in particular of tissue paper, that includes at least two plies, at least one of which is embossed according to an embossing pattern that includes projections (1, 2, 3) with a density of 30 or more per cm. According to the invention, the embossing patterns include at least two adjacent zones whose projections (1, 2, 3) have, respectively, a different density and/or a different surface area at the peak so as to produce a relief effect on the product.Type: ApplicationFiled: March 5, 2004Publication date: November 25, 2004Applicant: Georgia-Pacific FranceInventors: Michel Basler, Benoit Hoeft, Sebastien Jeannot, Nicolas Pommier

Patent number: 6805766Abstract: The invention concerns an absorbent paper product with basic weight of about 36 to about 105 g/m2 comprising at least three pleats, a first and second outer embossed pleats each comprising raised patterns consisting at least partially of discrete protuberances oriented towards the inside of the structure and a non-embossed central pleat, the pleats being associated by linking the distal surfaces of at least part of the protuberances of each of the outer pleats to the central pleat. The invention is characterized in that each of the embossed outer pleats is linked by means of an adhesive to said central pleat, and at least one of the pleats has a pattern density more than 30 protuberances per cm2.Type: GrantFiled: June 11, 2003Date of Patent: October 19, 2004Assignee: Georgia-Pacific FranceInventors: Gilles Roussel, Benoît Hoeft

Patent number: 6746558Abstract: The object of the present invention is an absorbent paper product including at least three plies, and a method of manufacture therefore. The absorbent paper product is of an approximate specific surface weight between 36 and 105 g/m2, and includes at least three plies, namely a central ply and two embossed upper and lower outer plies each including salient patterns composed of at least in part discrete protrusions. The plies are joined by joining at least part of the protrusions of each of the outer plies to the central ply. At least one of the outer plies has a pattern density larger than 30 protrusions/cm2. The embossed lower outer ply (2) includes combined high and low patterns (5 and 7) of respective heights (H) and (h). The central ply (4) and the embossed upper outer ply (3) are joined in the nested mode to the embossed lower outer ply (2) at the level of at least part of the tops of the high pattern (5) of height (H) of the embossed lower outer ply (2).Type: GrantFiled: March 5, 2003Date of Patent: June 8, 2004Assignee: Georgia-Pacific FranceInventors: Benoît Hoeft, Pierre Graff

Patent number: 4888913Abstract: A machine for laying plastic film on a substrate which comprises supporting rollers (32 to 37) on which drum (16) is placed. One of the chassis wheels (6, 8) drives the drum through a transmission system (40) including a mechanical variable speed drive (60) enabling the transmission ratio between the traction wheel and the drum drive rollers to be varied. It is thereby possible to limit the tension forces exerted on the film when laying the film, making it possible to adapt the film to an uneven substrate, such as furrows or ridges on the ground in agricultural uses.Type: GrantFiled: February 10, 1988Date of Patent: December 26, 1989Assignee: Kaysersberg S.A.Inventor: Benoit Hoeft
