An absorbent article including an absorbent core sandwiched between a liquid-permeable topsheet and a liquid-impermeable backsheet, wherein the absorbent core includes an absorbent component enclosed by a core cover including an upper side and a lower side, and a sealing arrangement for joining the upper and lower sides and including two channel sealings in the crotch portion defining a first channel sealing width and a second channel sealing width. The channel sealings are formed by thermo and/or mechanical welding pattern including a plurality of welding spots being arranged in the form of a first row along the longitudinal axis in which each welding spot extends along a first axis, and a second row along the longitudinal axis in which each welding spot extends along a second axis, the first axis and second axis defining a first angle in relation to each other.

A method including: a conveying step of conveying a continuous sheet to be a component of a disposable worn article in a longitudinal direction; a printing step of repeatedly printing a predetermined pattern by spraying ink from a first group of nozzles of an inkjet print head onto a surface of the continuous sheet; and a flushing step of performing a flushing operation of spraying ink from at least a second group of nozzles of the head onto the surface of the continuous sheet.

A method of analysing the quality of a welding area of an absorbent sanitary article is disclosed. During a learning step, a plurality of welding operations are performed both with a sufficient quality and with an insufficient quality, and the welding area generated for each welding operation is monitored via a camera. During a training step, the pixel data of the welding areas monitored during the learning step is processed for training a classifier configured to estimate a welding quality as a function of respective pixel data of a respective welding area. Accordingly, during a normal welding operating step, the welding quality may be estimate via the classifier, thereby improving the environmental sustainability of the production process.

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. Aspects of the methods for assembling elastomeric laminates may utilize elastic strands supplied from beams that may be joined with first and second substrates, and may be configured to carry out various types of operations, such as bonding and splicing operations.

The present disclosure relates to assembling elastic laminates that may be used to make absorbent article components. Methods herein may include an anvil adapted to rotate about an axis of rotation, wherein first and second spreader mechanisms adjacent the anvil roll are axially and angularly displaced from each other with respect to the axis of rotation. During the assembly process, a substrate may be advanced in a machine direction onto the rotating anvil. The first spreader mechanism stretches a first elastic material in the cross direction, and the second spreader mechanism stretches a second elastic material in the cross direction. The stretched first and second elastic materials advance from the spreader mechanisms and onto the substrate on the anvil roll. The combined and elastic materials may then be ultrasonically bonded together on the anvil to form at least one elastic laminate.

Disclosed is a method for transferring cut-out nonwoven material members, the method including feeding a continuous web of a nonwoven material towards cutter and anvil roll, passing the continuous web between the cutter and anvil roll, the cutter roll having knives protruding from the circumferential surface, the knives having an edge with a first outline shape seen in a circumferential direction of the cutter roll, cutting the continuous web thereby forming cut-out nonwoven material members having a second outline shape corresponding to the first outline shape of the respective edge of the knives, and transferring the cut-out members to a vacuum roll having an outer circumferential surface that includes a plurality of vacuum ports arranged in a pattern, the pattern including pattern units each having a third outline shape, the pattern units fitting within the second outline shape of the cut-out members.

An individually wrapped absorbent article that includes an absorbent article, and a wrapping sheet configured to wrap the absorbent article is provided. The wrapping sheet is folded toward an inner surface of the wrapping sheet so as to cause a first region including one end in a first direction of the wrapping sheet and a second region including an opposite end in the first direction to overlap with each other, and a seal portion is formed at each edge portion in a second direction of the wrapping sheet. The second direction is perpendicular to the first direction. The seal portion includes a plurality of compressed recesses and compressed projections along the first direction. The compressed projections are formed between the compressed recesses.

Aspects of the present disclosure relate to methods and apparatuses for manufacturing absorbent articles, wherein discrete zones of protrusions may be formed on a substrate. In some configurations, the protrusions may be formed as hooks. When forming the discrete zones of protrusions, localized speed variances may be imparted to the advancing substrate to ensure the adequate time to form the protrusions is provided. As such, protrusions may be formed on portions of the substrate that have been temporarily stopped or slowed to relatively slow speeds. The substrates with zones of protrusions may then be incorporated into products, such as assembled absorbent articles, so as to place the protrusions in desired positions on the absorbent articles. As such, the methods and apparatuses herein allow for the use of hook forming techniques on substrates in article manufacturing processes that provide flexibility in such configurations without sacrificing desired manufacturing speeds.

The methods herein relate to assembling an elastic laminate with a first elastic material and a second elastic material bonded between first and second substrates. During assembly, an elastic laminate may be formed by positioning the first and second substrates in contact with stretched central regions of the first and second elastic materials. The elastic laminates may include two or more bonding regions that may be defined by the various layers or components of the elastic laminate that are laminated or stacked relative to each other. In some configurations, a first plurality of ultrasonic bonds are applied to the elastic laminate to define a first bond density in the first bonding region, and a second plurality of ultrasonic bonds are applied to the elastic laminate to define a second bond density in the second bonding region, wherein the second bond density is not equal to the first bond density.

A method for producing washable absorbent garments, wherein blank washable absorbent garments are folded to overlap to each other side edges of rear and front waist sections, and wherein the overlapped side edges are welded along respective welding lines and simultaneously cut flush with the respective welding lines.
