  • Publication number: 20080029235
    Abstract: An absorbent cellulosic sheet having variable local basis weight includes a papermaking-fiber reticulum provided with (i) a plurality of cross-machine direction (CD) extending, fiber-enriched pileated regions of relatively high local basis weight interconnected by (ii) a plurality of elongated densified regions of compressed papermaking fibers. The elongated densified regions have relatively low local basis weight and are generally oriented along the machine direction (MD) of the sheet and have an MD/CD aspect ratio of at least 1.5. The products are most preferably prepared by way of a compactive dewatering/wet crepe process.

  • Publication number: 20050103455
    Abstract: The present invention is a method of making a near-premium quality paper product having good strength and absorbency characteristics and a product made by that method. The invention is also a method for retaining a high ash content within a paper web formed by conventional wet pressing. The present invention is also a method for retaining a high percentage of softening agent within a paper web that includes such an agent. Further, the present invention is a soft absorbent paper product having a high void volume. Finally, the invention is also a method for producing a soft, absorbent, and near premium paper product having a high void volume using an undulatory crepe blade having a multiplicity of serrulations in its rake surface which presents differentiated creping angles and/or rake angles as to the paper being creped.

  • Patent number: 6374723
    Abstract: A drip ring for use with a hydraulic cylinder is provided. The drip ring is prefabricated from a flexible material. To size the prefabricated drip ring, the drip ring is cut and wrapped around the hydraulic cylinder that is to be fitted. The amount of excess drip ring material is measured and removed. The properly sized drip ring is then placed around the cylinder such that the two cut edges are positioned within a bonding fixture that has been pre-filled with a bonding compound. The inner flange of the drip ring is secured against the hydraulic cylinder with an adjustable, metal restraining strap. If desired, a drain fixture coupled to a drain pipe is attached to the fitted drip ring.

  • 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.
