Patent number: 6109473Abstract: A dispenser for sheets of fibrous material, such as a non-woven or cellulose wadding of a specific surface weight between 15 and 90 g/m.sup.2 per ply, a strip of the fibrous material wound into a roll and pre-perforated so as to provide a sequence of sheets linked to one another by rows of perforation bridges. The dispenser is fitted with a feed cone. The material is dispensed by the cone through a smaller diameter apex. The proportion of perforation bridges is selected to be no more than 30% above that constituting the machining limit of the fibrous material and in that the diameter of the apex of the cone is between a minimum value corresponding to a force of removal just exceeding the force of rupture of the material and a maximum value corresponding to an effectiveness equal to or larger than 90%, in particular equal to or larger than 95%.Type: GrantFiled: November 24, 1998Date of Patent: August 29, 2000Assignee: Fort James FranceInventors: Jean-Louis Neveu, Bernard Louis Dit Picard

Patent number: 6041701Abstract: The general application of the invention is a finishing process for an air-laid nonwoven web composed of short cellulosic fibers, bound by a thermoplastic binder and having a less than perfect homogeneous fiber distribution. In the invention, the process includes deforming under hot stress the web between an undeforming hard engraved cylinder and a slave cylinder having a hardness between about 60 and 90 degrees shore hardness D. The slave cylinder is resilient and deformable at the pressure applied to it by the engraved cylinder. In particular, the invention applies to the manufacture of webs and of disposable, decorative napkins.Type: GrantFiled: November 9, 1998Date of Patent: March 28, 2000Assignee: Fort James FranceInventors: Bernard Louis Dit Picard, Henri Lesage, Jean-Louis Neveu

Patent number: 5762288Abstract: An anti-theft dispenser of material wound in a core-free roll. The dispenser includes a substantially planar support and a shaft to support the roll which is perpendicular to the support. The shaft is fitted at its free end with a stop and a compressible anti-extraction element which is axially rotatable on the shaft and is mounted perpendicularly to the support to prevent extraction of the roll in a direction away from the support. The dispenser is characterized in that the compressible anti-extraction element includes a plurality of flexible, compressible anti-extraction rings.Type: GrantFiled: May 29, 1996Date of Patent: June 9, 1998Assignee: Fort James FranceInventors: Jean-Louis Neveu, Rudolph W.

Patent number: 4084930Abstract: Apparatus for the production of yarn having a potential crimp which is achieved by varying the viscosity gradient in the mass of polymer upstream of the spinneret. The apparatus includes means for feeding polymer under pressure, a block which is connected to the outlet of the feeding means and a spinning head, including a spinneret formed with at least one row of holes, the spinning head being mounted on the block. At least one passage is defined through the block, for the passage of polymer from the feeding means to the spinneret, this passage having a frusto-conical upstream portion which converges in a downstream direction towards the spinneret. Heating or cooling means are provided on the block for imparting to the polymer, as it passes through the passage, a temperature differential between the polymer at the center of the passage and the polymer at the walls of the passage.Means are also provided for receiving and possibly drafting the yarn which has been extruded through the spinneret.Type: GrantFiled: October 26, 1976Date of Patent: April 18, 1978Assignees: Sylvio Melancon, Agence Nationale de Valorisation de la RechercheInventors: Jean-Louis Neveu, Sylvio Melancon
