摘要:
Dispensable sheet material includes opposite side edges spaced apart from one another to define the overall width of the sheet material. Zones of weakness are spaced along the sheet material. Adjacent zones of weakness are spaced apart by a distance of from about 50% to about 200% of the overall width of the sheet material to divide the sheet material into a plurality of sheet material segments. Each of the zones of weakness comprises a plurality of perforations and frangible sheet material portions. Each of the frangible sheet material portions has a width of from about 0.3 mm to about 1.8 mm. The total width of the frangible sheet portions in each zone of weakness is from about 10% to about 30% of the overall width of the sheet material. The sheet material has an elasticity in the dispensing direction of from about 4% to about 20%. The sheet material has a dry tensile strength in the dispensing direction of from about 4,000 grams per 3 inches of width to about 12,000 grams per 3 inches of width. The sheet material has a wet tensile strength in the weakest direction, typically, a direction orthogonal to the dispensing direction, of at least about 900 grams per 3 inches of width. In addition, the sheet material has a tensile ratio of less than about 2.0. A dispensing system includes a dispenser defining an interior for containing the sheet material and an outlet for allowing sheet material to be dispensed from the interior of the housing.

摘要:
The present invention is a method of applying a chemical treating agent to a cellulose web. The invention is further a means of increasing the bulk, absorbency and pattern definition in an embossed cellulose web without losing softness in the web. Finally, the invention includes products produced by the foregoing processes.
摘要:
The invention relates to embossing multi-ply paper products, for example, paper towels, tissue and napkins, in which an improved embossing arrangement is used which is particularly suitable for paper products which have been processed so as to impart undulations whose axes extend in a principal undulatory direction, typically in the machine direction. The absorbent sheet typically further includes undulations which extend in the cross (transverse direction) of the web such that the absorbent sheet has a biaxially undulatory structure. The undulations may be formed by the use of an undulatory creping blade. Defined parameters accommodate: the distance at which the undulations are spaced, the total surface area of the design (embossing) elements, the width and length of the embossing elements and the aspect ratio of the elements, as well as the angular orientation of the embossing elements with respect to the undulations.

摘要:
A paper towel dispenser includes a housing with an inner chamber configured to support a paper supply and a dispensing aperture for dispensing paper from the paper supply. The paper supply includes a side that is formed by superimposed edge portions of paper from the paper supply. An indicator mechanism is affixed to the housing within the inner chamber and is disposed adjacent the paper supply. The indicator mechanism includes an indicator operably connected to a release mechanism. The indicator is movable between a retracted position and an indicating position. The release mechanism is pivotally biased away from the housing and is releasable in response to the paper supply being reduced below a predetermined amount. Upon release of the release mechanism, the release mechanism causes the indicator to move to the indicating position.
摘要:
A paper towel dispenser dispenses towels from a paper supply and includes a dispenser housing a low-reserve indicator mechanism for indicating when a reserve quantity of the paper supply is low. The dispenser housing has a housing wall structure on which the low-reserve indicator mechanism is affixed. The paper supply has vertically super imposed edge portions which form an outwardly facing vertical side of the paper supply. The low-reserve indicator mechanism includes an indicator mounted for movement between a retracted position and an indicating position for establishing a low-reserve indication detectable from outside of the dispenser house. The indicator mechanism also includes a release mechanism adapted to be spring-biased into contact with the vertical side of the paper supply. The release mechanism is released for movement in response to becoming unsupported by a diminishing height of the vertical side of the paper supply to cause the indicator to move to its indicating position.
