    摘要： This invention relates to apparatus and methods for intermittently bonding a substrate web in fabricating a blank subassembly for an absorbent article. The invention comprises ultrasonic bonding apparatus including an anvil roll, a substrate web thereon, and at least one rotary ultrasonic horn. The substrate web can comprise at least first and second layers of material. The rotary ultrasonic horn, in combination with the anvil roll, ultrasonically bonds intermittent segments of the first and second layers of the substrate web to each other. Such intermittent bonds can comprise end seals for the absorbent articles. The ultrasonic horn and anvil roll are periodically separated from each other to provide the intermittent bonding of the substrate web. An actuator apparatus periodically moves the anvil roll and ultrasonic horn from engaging contact with each other preventing bond formation. The actuator apparatus can include a cam mechanism moving one of the anvil roll and ultrasonic horn from engaging contact with the other during rotation of the rotary ultrasonic horn. The cam mechanism can create a physical gap between the ultrasonic horn and the anvil roll. The cam mechanism moves either the ultrasonic horn and the anvil roll toward the other of the ultrasonic horn and anvil roll at a velocity of no more than about 80 millimeters/second to prevent bounce or impact loading when the horn and anvil roll are in engaging contact. The anvil roll comprises a substrate-receiving surface generally moving the substrate web through the nip at a surface speed of at least 300 meters per minute. The ultrasonic system generally creates bonds between the first and second layers of the substrate web at least about 600 times per minute.

    摘要： The present invention is directed to reducing the build up or accretion of adhesive, alone or in combination with other materials, on the surfaces of equipment used to ultrasonically treat a workpiece (e.g., ultrasonically bonding various components or pieces to one another.) Thus the invention encompasses composites, absorbent products, and methods of making said composites and products where an adhesive composition having certain identified properties is used to reduce the build up or accretion of the adhesive on ultrasonic bonding equipment. In one embodiment of the invention, a composite includes an adhesive having a capillary-viscosity value of about 7 Pas·sec or greater and a Shore-OO-Hardness value of about 65 or greater, whereby the relative accretion value is less than about 1, and more particularly less than about 0.5.

    摘要： The present invention provides a diaper which includes an outer cover, a bodyside liner which is superposed on the outer cover and which includes a bodyfacing surface, an absorbent core which is located between the outer cover and the bodyside liner, and an adhesive. The adhesive is located on the bodyfacing surface of the bodyside liner. The adhesive is configured to at least temporarily secure the front portion of the diaper to a wearer's body to assist in positioning and fastening the diaper about the wearer's body. In a particular aspect, the adhesive is configured to provide a peel strength of no more than about 300 grams per centimeter of width and an initial shear strength of no more than about 600 grams per square centimeter.

    摘要： An absorbent article with an adhesive flap. The absorbent article has a crotch region, a rear waist region, and a body facing surface positionable adjacent a wearer when the article is in use. The absorbent article includes a backsheet, a liquid permeable topsheet attached to the backsheet, an absorbent structure disposed between said topsheet and said backsheet, and a flap positioned in the rear waist region of the article. The flap has first and second oppositely facing major surfaces wherein the first major surface faces the topsheet and the second major surface forms a portion of the body facing surface of the absorbent article. A substantial portion of the front edge of the flap is a free edge and an adhesive is disposed on the body facing major surface of the flap whereby the adhesive may engage the skin of the wearer when the absorbent article is in use. The adhesive flap thereby prevents the formation of a gap between the absorbent article and the wearer's skin near the rear waist region and, thus, inhibits the leakage of bodily exudates from the absorbent article.
