  • Patent number: 6197154
    Abstract: A method for making a textured tissue sheet on a conventional tissue making machine using a conventional cylindrical drum dryer creates a product that is remarkably bulky, soft, and wet resilient. A combination of rush transfer and sheet molding with three-dimensional fabrics is combined with the step of web inversion to ensure that the surface of the web which was molded onto a first textured transfer fabric is the surface which is placed against the surface of the cylinder dryer. Web inversion improves machine productivity and enhances physical properties of the web.

  • Patent number: 6187137
    Abstract: A method of using a conventional wet-pressed creped tissue machine produces a textured tissue sheet that is dried on a conventional cylindrical drum dryer to create an uncreped product with throughdried-like properties. Machine modifications and a proper balance of adhesive compounds and release agents permit a textured sheet to be dried on a Yankee drier and then pulled off without use of a crepe blade.

  • Patent number: 6083346
    Abstract: A tissue sheet is made using a modified wet pressing process employing an integrally sealed air press. After initial formation and conventional vacuum dewatering, the wet web is conformed to the surface contour of a relatively coarse fabric to give the web a textured surface. By creating a pressure differential across the web of at least 30 inches of mercury and an air stream through the web of at least 500 SCFM/in.sup.2, the air press noncompressively dewaters the wet web to a consistency of about 30 to about 40 percent prior to a Yankee dryer. The web is dried to substantially preserve its three-dimensional, throughdried-like texture. The resulting web has an exceptionally high degree of bulk and absorbency not previously found in wet-pressed products.
