Absorbent article having a waist gasketing element
The present disclosure relates to absorbent articles having a waist gasketing element, with the gasketing element having an adhesive zone and one or more adhesive-free zones. At least a portion of the waist gasketing element is adhesively attached to a chassis of the absorbent article. Additionally, a portion of the waist gasketing element is mechanically attached to a portion of the absorbent article.
RADIAL PNEUMATIC DISTRIBUTION SYSTEMS AND METHODS USEFUL FOR MAKING SIDE SEAMS ON COMPONENTS OF ABSORBENT ARTICLES
The present disclosure provides radial pneumatic distribution systems, methods, and apparatuses, for example, drums, configured to bond web materials together utilizing a rotating drum having fluid nozzles and fluid flow sensors associated with the housing of the drum and configured to rotate with the drum about a central longitudinal axis as the drum rotates.
ABSORBENT ARTICLE HAVING A WAIST GASKETING ELEMENT
The present disclosure relates to absorbent articles having a waist gasketing element, with the gasketing element having an adhesive zone and one or more adhesive-free zones. At least a portion of the waist gasketing element is adhesively attached to a chassis of the absorbent article. Additionally, a portion of the waist gasketing element is mechanically attached to a portion of the absorbent article.
Method for manufacturing absorbent sanitary products
A method for manufacturing absorbent sanitary products, comprising the steps of: forming a first and a second continuous elastic band, which are movable parallel to each other in a machine direction, fixing a plurality of absorbent panels between said first and second continuous elastic bands, arranged in a direction transverse to the machine direction, and spaced apart in said machine direction, wherein each of said elastic bands is formed by means of a method comprising the steps of: continuously feeding a plurality of tensioned elastic threads (30) in said machine direction, continuously feeding a pair of non-elastic webs arranged on opposite sides of said plurality of elastic threads, welding said pair of non-elastic webs to each other by means of a welding pattern comprising anchoring welds and/or containing and guiding welds.
Method and apparatus for bonding elastic parts under tension to an advancing carrier
The present disclosure relates to methods and apparatuses for stretching, transferring, and bonding elastic parts under tension to an advancing carrier substrate during the assembly of absorbent articles. A continuous carrier substrate may be advanced in a machine direction at a first speed, and a discrete elastic part may be cut from a continuous elastic substrate having a direction of stretch in a cross direction. The speed of the discrete elastic part is changed from a second speed to the first speed, and the central region of the discrete elastic part is stretched in the cross direction. The discrete elastic part is bonded with the continuous carrier substrate such that the stretched central region extends in the cross direction between the first and second longitudinal edges of the continuous carrier substrate. The discrete elastic part may also be bonded with the carrier substrate with adhesive and/or mechanical bonds.
Hydro-enlarged, apertured non-woven web and method of making same
A hydro-enlarged apertured non-woven web includes a plurality of fibers with a plurality of bond points, a first surface defining a planar top, and a second surface defining a planar bottom. The second surface is separated from the first surface by a first distance defining a loft. A plurality of apertures extending through the non-woven web. The plurality of apertures is formed by spraying a fluid against an unapertured precursor web, causing a plurality of pins disposed on a pinned roller to punch through the unapertured precursor web. The unapertured precursor web has a third surface defining a planar top and a fourth surface defining a planar bottom, where the third surface is separated from the fourth surface by a second distance defining a precursor loft. The loft is greater than the precursor loft by a loft increase within a range of 50-110%.
