  • Patent number: 11878322
    Abstract: A system and process are disclosed for applying an adhesive composition to a moving web of material. During the process, a web of material is conveyed very rapidly adjacent to a nozzle of an adhesive applicator. A defecting device periodically deflects the web into contact with a surface of the nozzle. An adhesive flow control device is used to control the flow of adhesive through the nozzle. Adhesive flows through the nozzle and is timed with the deflection device. In one embodiment, the flow of adhesive is started prior to contact with the web. In this manner, treated discrete areas of the adhesive composition can be formed on the web. The treated discrete areas can have lengths that are minimized through the process of the present disclosure allowing for adhesive to be applied at extremely fast speeds.

  • Patent number: 11712377
    Abstract: Absorbent articles of the present disclosure may be constructed with a secondary liner sheet placed on top of a body facing liner of the articles configured to form a pocket. The pocket provides a barrier, thereby separating a front region of the absorbent articles from a rear region. In this manner, the absorbent articles of the present disclosure may reduce the spread of bodily exudates throughout the articles. The reduced spreading of exudates may help to keep skin healthy by reducing the amount of skin exposed to the skin irritants within the exudates and/or by preventing additional skin irritants from being created by preventing the mixing of BM and urine, at least in proximity to the skin of the wearer.

  • Publication number: 20230018501
    Abstract: Absorbent articles and methods of manufacturing absorbent articles are disclosed. A method for forming a plurality of absorbent articles may comprise advancing a first web in a first direction, attaching first and second elastomeric rear side panel materials to first and second side edges of the first web and forming a first chassis width, attaching first and second elastomeric front side panel materials to the first and second side edges of the first web and forming a second chassis width, and severing the first web through the first and second elastomeric front side panel materials and through the first and second elastomeric rear side panel materials to form a plurality of individual absorbent articles, wherein a ratio of the first chassis width to the second chassis width is between about 1.5 and about 3.0.

  • Publication number: 20200113744
    Abstract: A unique and distinctive adhesive pattern is applied to a base web, such as a nonwoven web. The adhesive pattern can include a plurality of treated discrete areas that can extend parallel in the longitudinal direction of the web. Each treated discrete area can include a head portion connected to a tail portion. The head portion, in one embodiment, can have a greater amount of adhesive composition based on mass per area in relation to the amount of adhesive composition contained in the tail portion. The overall length of the treated discrete area can be relatively short in relation to adhesive patterns produced in the past using conventional slot coating processes. The adhesive pattern provides a secure attachment to an adjoining material and can provide various processing advantages.
