Methods and apparatuses herein relate to assembling absorbent articles, and more particularly, diapers, each including a chassis connected with front and back elastic belts. Opposing end regions of the chassis are connected with regions of the elastic belts where the elasticity of the elastic belts has been removed or deactivated. An elastic laminate is formed by intermittently bonding elastic strands between a first continuous substrate layer and a second continuous substrate layer. The elastic strands are then intermittently deactivated by severing the strands in the non-bonded regions to form deactivated regions of the elastic laminate. A plurality of chassis may then be bonded with the elastic laminate, wherein the first or second end regions of each chassis may be bonded with deactivated regions of the continuous elastic laminate.

Absorbent products comprising foam material

An absorbent product includes a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core enclosed between the topsheet and the backsheet. The absorbent core includes an absorbent fibrous layer and a liquid inlet foam layer and the absorbent core includes a transversally central liquid inlet region extending in the longitudinal direction of the absorbent core. Within the liquid inlet region, the liquid inlet foam layer is covered by a plurality of inlet openings and has a transversal width, which is equal to, or up to 9 mm smaller than, the minimum transversal width of the absorbent fibrous layer. The liquid inlet foam layer also has side edge regions arranged in front and rear portions of the absorbent core transversally outside of the liquid inlet region, and within which the liquid inlet foam layer is free from liquid inlet openings.

METHOD OF APPLYING FASTENER ELEMENTS FOR DISPOSABLE ABSORBENT GARMENT

Methods of making disposable absorbent articles and disposable absorbent articles that comprise: a first, second, and third fastener elements to a web such that: the first fastener element is spaced from the second fastener element by a first distance along a length of the web; the second fastener element is spaced from the third fastener element by a second distance along the length of the web; and the second fastener element is disposed between the first and third fastener elements.

DEVICE FOR APPLYING SEGMENTS OF ABSORBENT ARTICLES
20200229986 · 2020-07-23 ·

A device for applying segments of absorbent articles includes a cutting station for cutting a continuous web into segments and an applicator station for applying each segment on a respective absorbent article. A plurality of carrier units, each includes a pad for retaining and transferring a segment from the cutting station to the applicator station. The pad fully rotates about a main axis to transfer the segment from the cutting station to the applicator station and return to the cutting station and, from the cutting station to the applicator station, rotates at least 90 about its axis of rotation to orient the segment transverse to the feed direction of the absorbent article. A first movement member moves one or more first carrier units about the main axis and a second movement member moves one or more second carrier units separately from the first carrier units about the main axis.
