Fabric crepe process for making absorbent sheet
ActiveUS7399378B2High speed transmissionGuaranteed high speed operationNatural cellulose pulp/paperMechanical working/deformationFiberAdhesive
A process for making absorbent cellulosic paper products such as sheet for towel, tissue and the like, includes compactively dewatering a nascent web followed by wet belt creping the web at an intermediate consistency of anywhere from about 30 to about 60 percent under conditions operative to redistribute the fiber on the belt, which is preferably a fabric. In preferred embodiments, the web is thereafter adhesively applied to a Yankee dryer using a creping adhesive operative to enable high speed transfer of the web of intermediate consistency such as a poly(vinyl alcohol) / polyamide adhesive. An absorbent sheet so prepared from a papermaking furnish exhibits an absorbency of at least about 5 g / g, a CD stretch of at least about 4 percent, and an MD / CD tensile ratio of less than about 1.1, and also exhibits a maximum CD modulus at a CD strain of less than 1 percent and sustains a CD modulus of at least 50 percent of its maximum CD modulus to a CD strain of at least about 4 percent. Products of the invention may also exhibit an MD modulus at break 1.5 to 2 times their initial MD modulus.

Cassette for holding ink ribbon and print paper therein and printer incorporating the cassette therein
An ink ribbon-print paper cassette is used in a thermal printer. A paper tray accommodates a stack of single sheets of print paper. The paper tray has an opening through which the print paper is fed into a paper path on a sheet-by-sheet basis. An ink ribbon for thermal printing runs over a thermal head located adjacent the paper tray. A housing accommodates the paper tray, thermal head, and ink ribbon therein. When the cassette is loaded into the thermal printer, the outer surface of the cassette and an inner wall of the thermal printer cooperate to form a paper path therebetween through which each of the sheets of print paper is advanced from the paper tray to the thermal head.
