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.

Abstract: A creping blade for creping a cellulosic web from a rotatable cylinder in a creping process includes first and second side faces. The first side face is at least substantially opposite to the second side file. The blade also includes an upper surface adjacent to the first and second side faces. A plurality of notches is provided along the upper surface. Each of the notches has a bottom portion and an open end defined by at least a portion of the upper surface. The notches are configured to increase the caliper of the cellulosic web when the creping blade crepes the cellulosic web from an outer surface of the rotatable cylinder. Creped paper and improved methods of manufacturing paper are also provided.

Abstract: An especially soft creped tissue can be produced by the indirect addition of chemical softening agents to the tissue web by applying the chemical softening agents to the surface of the Yankee dryer, such as by spraying. More specifically, the softening agents can be included as part of the creping adhesive formulation, which is sprayed onto the surface of the Yankee dryer between the creping blade and the pressure roll. The softening agents are subsequently transferred to the tissue sheet surface as the sheet is pressed against the Yankee dryer.

Abstract: In a paper machine having a roll rotating about an axis extending in a cross machine direction, and having a doctor blade applied to the roll surface by a blade holder parallel to the axis and carried on a doctor back, an apparatus is provided for accommodating relative movement between the blade holder and the doctor back in the cross machine direction during mounting and removal of the blade holder. The apparatus comprises a rail fixed to the doctor back and extending longitudinally in the cross machine direction. A groove extends along the length of the guide rail. The groove has a bottom, a width measured between confronting sides, and a top defined by ledges projecting inwardly from the sides, with inner edges spaced one from the other to define a slot that underlies the blade holder and has a width narrower than the width of the groove. A plurality of shafts are spaced along the length of the blade holder and project downwardly through the slot and into the groove. First and second independently rotatable elements are carried by each of the shafts. The first rotatable elements are located in the slot and are dimensioned to contact the inner edges of the ledges, and the second rotatable elements are located in the groove and are dimensioned to contact the undersides of the ledges.

Abstract: An apparatus for increasing bulk of a foreshortened fibrous web includes a working surface designed to receive a foreshortened web thereon, a means for adding moisture to at least selected portions of the web thereby relaxing the crepe in the selected portions, and a means for retaining the crepe in the rest of the web. A preferred apparatus includes a pair of opposite surfaces, at least one of which having expansion conduits therethrough, the web being impressed between the surfaces. A temperature differential is created between the two opposite surfaces, sufficient to drive the moisture added to the selected portions therethrough, thus relaxing the crepe in the selected portions which expand into the expansion conduits, while the crepe is retained in the rest of the web impressed between the two surfaces.

Abstract: A non-oil-based release aid used in a creping process for releasing a paper web from a Yankee dryer in the manufacture of a paper product having a formula for its block version as follows: R—(OC3H6)y(OC2H4)zOH; where R is a C8 to C20 alkyl or alkylaryl group, y plus z is greater than 20, and y is greater than z. The y moles of propylene oxide (OC3H6) and the z moles of ethylene oxide (OC2H4) may be added in random or block fashion. Examples of the chemical compound for the release aid are alkoxylated alkylphenols, alkoxylated fatty acids, and alkoxylated alcohols. A preferred chemical compound is an alkoxylated tall oil fatty acid. The release aid may optionally comprise from about 0% to about 20% by weight of an emulsifying surfactant. The release aid may comprise 70% to 100% by weight of the chemical compound, 0% to 20% by weight of emulsifying surfactants, and 0% to 10% by weight water. The release aid provides lubrication between the doctor blade and the Yankee dryer; allows the release of the paper web from the Yankee dryer, and improves the absorbency of the paper product.
