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.

An electronically controlled roll towel dispenser with a data communication system. The dispenser automatically dispenses a predetermined length of paper toweling from a supply roll after a length of toweling has been detached by a user pulling and tearing the protruding toweling against a stationary cutting blade. The dispenser is battery powered with an electric motor, an electromechanical dispensing mechanism, and an embedded microcontroller for controlling and monitoring operation of the dispenser. In addition to primary control functions, the microcontroller monitors parameters such as battery condition, towel usage, system status, system errors, and unsafe operating conditions. Pushbutton switches are also provided for programming towel length and the dispense delay. The dispenser further includes an optical transmitter for transmitting visual and infrared data to a receiving device. Useful information about the status of the dispenser can be visibly discerned by an operator through the use of primitive low-speed flash patterns, while high-speed infrared digital data can be simultaneously embedded in or multiplexed with the visible data.

An absorbent paper sheet is treated with an aqueous wax dispersion such that the sheet includes a fused wax and emulsifier residue in an amount of from about 1 to about 20 weight percent of the sheet based on the combined weight of the fiber, wax residue and an emulsifier residue in the sheet. The fused wax emulsion operates to make at least one surface of the sheet laterally hydrophobic, exhibiting a moisture penetration delay of at least about 2 seconds and less than about 40 seconds as well as a typical contact angle with water at one minute of at least about 50 degrees. There is thus provided absorbent products which exhibit both absorbency and resistance to moisture penetration. The treated sheet further exhibits microbial barrier properties, impeding transfer of bacteria, for example, through the sheet. There are produced tissue products which resist moisture penetration from propelled liquids as well as sequester sorbed liquids in the interior of the tissue.

Single-ply throughdried tissue sheets, particularly suitable as bath tissue, are produced with at least three layers. One or both of the outer layers suitably contain predominantly softwood fibers and a chemical bonding agent. One or more of the inner layers suitably contains a chemical debonder. The resulting tissues have a high level of durability and softness.

Each of the patterns includes treated and untreated areas. The patterns are positioned on the paper product such that untreated areas on one surface are in correspondence with the treated areas on the other surface of the sheet.

A dual intensive property tissue. The tissue has a first set of intensive properties including density, surface area, thickness and void volume as presented to the consumer. The consumer plastically activates the tissue by pulling it in tension. A series of slits 44 or other lines of weakness elongate in a direction parallel to the line of tension, allowing the tissue to achieve a second state of intensive properties. The value of the second state of intensive properties is different after activation. The change in value of the intensive properties allows for economies in shipping, where a higher density product is shipped to the consumer. At the point of use, the consumer activates the product to achieve the increase surface area and lower density. The increase in surface area and concomitant decrease in density provides for increased efficacy in cleaning. The plastically activatable state may be provided by a series of slits 44 or other lines of weakness in the tissue. The tissue may comprise cellulosic and / or synthetic fibers. The tissue may be used as a facial tissue, bath tissue, paper towel, napkin, body wipe, mophead, etc.

Lightweight multi-ply tissue products, such as facial tissue and bath tissue, are produced by printing flexible polymeric binder material, such as certain latex binders, onto one or more inner surfaces of the multi-ply tissue product. The resulting products have low stiffness and high strength.

A first embodiment of this invention is a cleaning apparatus for a commercial conveyor belt that is mounted on a conveyor table. The cleaning apparatus is a housing that includes a spraying tube for dispensing a cleaning solution and a novel wiping device.
