    摘要： Disclosed are adhesive formulations as creping process aids for producing an absorbent creped cellulosic sheet having a high level of surface-perceived softness that comprises continuously forming a web of cellulosic papermaking fibers, adhering said web to a thermal drying means by means of adhesive compositions comprising polymers having at least one primary or secondary amine group in the backbone such as chitosan, polyvinylamine, polyvinyl alcohol-vinyl amine and polyaminoamide in combination with crosslinking agents such as dialdehydes or zirconium compounds having a valence of plus four including ammonium zirconium carbonate, zirconium acetylacetonate, zirconium acetate, zirconium carbonate, zirconium sulfate, zirconium phosphate, potassium zirconium carbonate, zirconium sodium phosphate and sodium zirconium tartrate and creping said treated web from said thermal drying means. In the method for producing the absorbent creped cellulosic sheets, the zirconium crosslinking agent is advantageously applied directly and separately on the Yankee dryer at the time the base polymer is applied to the surface. Alternatively, when using dialdehydes, the dialdehydes are mixed with the base polymer just prior to application to the Yankee dryer surface without having the crosslinking reaction take place with the base polymer prior to reaching the heated Yankee surface. These sheets are useful in the manufacture of tissue and towel.

    摘要： A support spindle adapts a toilet tissue dispenser cabinet designed for use with conventional toilet tissue rolls having cores for use with coreless toilet tissue rolls. The support spindle includes a roll stop which is used to position a coreless roll at different locations on a rotatable sleeve incorporated on the support spindle. An insert positioned in the cabinet is employed to prevent premature actuation of a roll drop-down mechanism employed in the cabinet.

    摘要： 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. After passing by the infrared drying unit, the fabric sheet then conveys the paper web toward a final drying drum where the paper web is transferred from the fabric sheet to the final drying drum through the use of a pressure roll.
