  • Patent number: 10669086
    Abstract: An extensible slit sheet paper product is produced having an expandable slit pattern that forms open cells upon expansion of the paper product. The paper product is an extensible paper having an extensibility in the range from 1-9% in the machine direction and 1-5% in the cross direction. The expansion produces an array of hexagonal cells. The expanded extensible paper can be used to wrap an object for shipping by wrapping and cushioning the object in the expanded slit sheet material. The extensible, expandable slit sheet paper can be wrapped around itself to produce a void fill product.

  • Patent number: 9382663
    Abstract: Apparatuses, processes, and systems for determining features of a paper-making fabric. The apparatus, processes, and systems utilize a representation of a portion of a surface of the fabric, with the representation showing locations and sizes of knuckles and pockets in the surface of the fabric. An image of the portion of the fabric is generated based on the representation. Using the displayed image, an outline is drawn around at least one of the knuckles, and guidelines are drawn such that the guidelines pass through the center of the outlined knuckle, pass through the other knuckles, and form a shape that surrounds areas of the image that correspond to where the pockets are formed between the knuckles. With the outlined knuckle and guidelines, properties that affect the paper-making functionality of the fabric may be calculated.

The techniques include forming a representation of a portion of the surface of the fabric, with the representation showing the knuckles and pockets in the surface. The representation can be formed, for example, in pressure measurement film, in wax paper, or as a photograph. An image is generated from the representation, and the image is analyzed to determine characteristics of the surface of the fabric, such as knuckle sizes and pocket sizes. The depth of pockets in the fabric can also be determined. The techniques can be used in processes for analyzing wear of a fabric, and for obtaining a fabric for making a paper product with a particular three-dimensional structure.

The dewatered web is applied to a translating transfer surface moving at a transfer surface speed. The web is belt-creped from the transfer surface utilizing a generally planar polymeric creping belt provided with a plurality of perforations through the belt, the belt-creping step occurring under pressure in a belt creping nip defined between the transfer surface and the creping belt. The belt travels at a belt speed that is slower than the transfer surface speed, and the web is creped from the transfer surface and redistributed on the creping belt to form a web. The web includes hollow domed regions, connecting regions, and transition areas. The web is dried to produce the belt-creped absorbent cellulosic sheet.

  • Patent number: 8470431
    Abstract: Embossed sheet materials are disclosed. In accordance with the present disclosure, the embossing pattern includes at least one line element that has a gradually decreasing depth. The gradually decreasing depth has been found to alter the shadow characteristics of the embossing pattern thus creating a line in the embossing pattern that appears to decrease in line weight. The decrease in line weight is accomplished without having to change the width of the embossment, although the width can also be changed in conjunction with the depth. Being able to incorporate line weight variations into embossing patterns can dramatically improve the aesthetic appeal of the patterns.

One embodiment of the present invention is a method for preparing chemically treated pulp fiber. A fiber slurry is created comprising process water and pulp fibers. The fiber slurry is transported to a web-forming apparatus of a pulp sheet machine thereby forming a wet fibrous web. The wet fibrous web is dried to a predetermined consistency thereby forming a dried fibrous web. The dried fibrous web is treated with a water insoluble chemical additive thereby forming a chemically treated dried fibrous web containing chemically treated pulp fibers.

  • Patent number: 7662256
    Abstract: The present invention is generally directed to paper products having great softness and strength and methods of making the paper products. The paper products are formed from one or more paper webs that can be made according to various methods. In one embodiment, the paper web is an uncreped through-air dried web. According to the present invention, at least one side of the paper web is treated with a bonding material according to a preselected pattern and creped from a creping surface. Through the process, a two-sided tissue web is formed having a smooth side and a textured side.

  • Patent number: 7503998
    Abstract: A method of making a fabric-creped absorbent cellulosic sheet is provided which includes dewatering a papermaking furnish and partially drying the web without wet-pressing before applying it to a translating transfer surface moving at a first speed. The process further includes fabric-creping the web from the transfer surface at a consistency of from about 30 to about 60 percent utilizing a creping fabric, the creping step occurring under pressure in a creping nip defined between the transfer surface and the creping fabric wherein the fabric is traveling at a second speed slower than the speed of said transfer surface, the fabric pattern, nip parameters, velocity delta and web consistency being selected such that the web is creped from the surface and redistributed on the creping fabric. After creping, the web is dried, preferably with a plurality of can dryers to a consistency of at least about 90 percent while it is held in the creping fabric.

  • Patent number: 7419569
    Abstract: A method of making soft, strong, high bulk tissue is disclosed. The method includes pre-conditioning a wet web by straining the wet web in the cross-machine direction prior to transferring the wet web to a throughdrying fabric. The pre-conditioned web provides improved sheet softness and conforms more readily to the surface contour of the throughdrying fabric, thereby creating greater caliper (bulk) in the resulting dried sheet. The bulk is maintained during a subsequent creping step by maintaining the dried sheet in registration with the throughdrying fabric when the dried sheet is applied to the surface of the creping cylinder.
