  • Patent number: 5727458
    Abstract: An embossing apparatus and method which provides a better embossed appearance and eliminates undesired roughness on the backside of the web material. Two plies are multilevel embossed between rigid engraved rolls and backup rolls, which may be either engraved or smooth. One rigid roll has embossing elements of varying heights and perforation elements, which run in a side-by-side relationship with the corresponding perforation elements on the opposing rigid roll in a nip region of the apparatus. The multiple plies are perforation bonded between the perforation elements, which are preferably the two highest elements, thus reinforcing the other multi-level embossed pattern formed in between the perforation bonds. The embossed patterns impart a quilt-like contoured appearance to the finished product.

  • Patent number: 5704566
    Abstract: A roll of paper toweling is dispensed from the opening of a dispenser due to a manual pulling force applied to the toweling. The toweling is separated into a plurality of toweling segments by a plurality of spaced tear lines, the tear lines being straight, parallel to each other, and extending orthogonally relative to the side edges of the paper toweling. The perforated tear lines are formed of a plurality of spaced, elongated, axially aligned slits separated by frangible toweling portions extending between the slits. The frangible toweling portions are narrower near the side edges of the toweling than in the middle thereof and the distances between the centers of the toweling portions are substantially the same along the length of the perforated tear line.

  • Patent number: 5695607
    Abstract: A one-ply paper tissue product and a method of making a one-ply paper product combining high strength and softness along with low sidedness. The paper tissue product exhibits a sidedness parameter of less than 0.3 preferably, less than 0.225, a tensile modulus of no more than 32 grams/percent strain, a GM MMD of no more than about 0.225, and a cross directional strength of at least 200 grams per 3 inches. In stratification tissues, these properties are obtained by control of stratification, particularly, chemical stratification and stratification of furnish when appropriate. The tissue has a sidedness parameter value of less than 0.3, preferably, about 0.15 to about less than 0.225. In homogenous tissue, these properties are obtained by adding a strength enhancing agent to separate furnish sources prior to the funish sources being combined, and further, optionally adding the softener to the nascent web.

  • Patent number: 5690788
    Abstract: The present invention relates to biaxially undulatory single-ply and multi-ply tissues, single-ply and multi-ply towels, single-ply and multi-ply napkins and other personal care and cleaning products as well as novel creping blades and novel processes for the manufacture of such paper products. The present invention is directed to tissue and towel product having highly desirable bulk, appearance and softness characteristics produced by utilizing a novel undulatory creping blade having a multiplicity of serrulations formed in its rake surface which presents differentiated creping angles and/or rake angles to the web as it is being creped. The invention is also directed to a novel blade having an undulatory rake surface having trough-shaped serrulations in the rake surface of the blade. The undulatory creping blade has a multiplicity of alternating serrulated sections of either uniform depth or a multiplicity of arrays of serrulations having non-uniform depth.

  • Patent number: 5679206
    Abstract: An apparatus and method for separating a tail from a roll of material. The apparatus includes a rotator for rotating a roll of material about its longitudinal axis and a tail loosener for loosening a tail from the roll. Air flowing from a duct passes over a tail supporting surface to extend the tail along the surface. The apparatus may be used to arrange a tail before the tail is sealed to the roll.

  • Patent number: 5674361
    Abstract: A creping system includes a Yankee dryer rotatable about its axis, a blade support mechanism which includes (a) a pair of guide rails, (b) a fixed attitude linear bearing engaging and translatable along each of the guide rails, each fixed attitude linear bearing being mounted on a block and (c) a combination linear-rotary bearing being carried by each block, the axis of each combination linear-rotary bearing being parallel to the generators of the surface of the Yankee dryer and collinear with the axis of the other combination linear-rotary bearing. A stub shaft engages each combination linear-rotary bearing, each stub shaft being translatable along, and rotatable about, the axis of its respective combination linear-rotary bearing. A blade holder is mounted between the stub shafts, and a blade mounted on the blade holder for engagement with the surface of the Yankee dryer.

  • Patent number: 5666744
    Abstract: A paper drying apparatus and method therefor including an infrared drying unit and a vacuum unit, wherein the infrared drying unit emits infrared radiation in a direction toward the vacuum unit. A fabric sheet for carrying a paper web is provided, wherein the fabric sheet passes between the infrared drying unit and the vacuum unit. The infrared drying unit is positioned on the side of the fabric sheet adjacent to the paper web and the vacuum unit is juxtaposed on the opposite side of the fabric sheet from the infrared drying unit, wherein the vacuum unit draws air through the paper web in a direction from the infrared drying unit toward the vacuum unit. The combination of the infrared drying unit with the vacuum units provides a compact arrangement which efficiently removes moisture from the paper web.
