  • Patent number: 9067396
    Abstract: A method of producing a composite sheet includes joining a first sheet in which stretchability in a longitudinal direction of the first sheet is developed by being subjected to a drawing process in the longitudinal direction and a second sheet having stretchability in a longitudinal direction of the second sheet that is lower than the stretchability of the first sheet. The longitudinal directions are aligned with each other. The first sheet is extended in the longitudinal direction, while transporting the first sheet in the longitudinal direction with the first sheet being in contact with an upstream roll and a downstream roll that rotate adjacent to each other. The second sheet is joined to a portion of the first sheet in an overlapped manner, the portion being in contact with the downstream roll in the extended state.

The wiping products are made from a web of material containing binder fibers alone or in combination with pulp fibers. Once the web is formed, the web is adhered to a creping surface and creped. According to the present invention, the web may be creped once or creped multiple times. Of particular advantage, the web can be adhered to a creping surface through the use of the binder fibers without the use of an adhesive.

  • Patent number: 6210528
    Abstract: A low density, wet-creped paper web having improved levels of tensile strength, tear strength and thickness. The web has a distribution of densified regions corresponding to the distribution of knuckles on a drying fabric. Generally speaking, these densified regions should be distributed so that the distance between at least a portion of the densified regions is less than or equal to the length of the longest fiber in the furnish (e.g., pulp fibers and/or other fibers) used to make the paper web. The wet-creped paper web is removed from a Yankee dryer at a dryness of between 45 and 65% and then passed to the after dryer section of a paper machine. An after dryer fabric is pressed into the wet base web to transfer the topography of the after dryer fabric to the web and to generate improved tensile strength, tear strength and thickness. The wet base web is pressed into the drying fabric utilizing a nip before the web is 70% dry.

  • Patent number: 6207011
    Abstract: A method for producing absorbent creped cellulosic sheets is disclosed. The process is carried out by applying zirconium crosslinking agent directly and separately on the Yankee dryer at the time the base polymer is applied to the surface. These creped sheets are useful in the manufacture of tissue and towel.

  • Patent number: 6187139
    Abstract: The present invention is a method for making a high quality paper product at improved process efficiency through the use of high steam levels in the Yankee dryer. The product according to the present invention is creped from the Yankee dryer while it is still wet and is then drying is completed using conventional methods. Products made according to the present invention exhibit improved absorbency, softness and bulk.

  • Patent number: 6129815
    Abstract: The present invention provides a multi-layered wiping product that maintains desired characteristics of softness, strength, stretchability, absorbency, and the like. The wiping product is formed from a process using a multi-layered paper web, printing a bonding agent on both of its outer surfaces, pressing the web so it adheres tightly to a creping surface and lightly to a presser roll, and then creping one of its surfaces.

  • Patent number: 6074526
    Abstract: A creping doctor blade and method of forming such blade including a thin flexible generally planar creping member having an elongated flexible, substantially prismatic body having a relieved substantially planar engagement surface adapted to bear against the drying cylinder. A rake face of the creping doctor blade extends generally outwardly relative to a surface of the rotatable drying cylinder when the creping blade engages the cylinder and the length of the substantially planar engagement surface is generally equivalent to the width of the drying cylinder with the width of the substantially planar engagement surface being selected so as to correspond to the wear pad dimension of a conventional blade used in the same processes and is generally in a range from about 0.005 inches to about 0.020 inches with the relief face of the blade adjacent to the rotatable drying cylinder having an elongated depression having a depth of at least about 0.

  • Patent number: 6066234
    Abstract: A process for producing a creped sheet as well as a creping blade and creped paper product formed by such blade is set forth with the process including the steps of adhering a cellulosic web to a moving surface, providing a stepped creping blade disposed to crepe the cellulosic web from the moving surface and creping the cellulosic web from the moving surface forms a creped paper product having greater bulk and absorbency than previously prepared creped paper products.
