Methods and apparatuses for making elastomeric laminates with elastic strands unwound from spools on surface unwinders

The present disclosure relates to methods for assembling elastomeric laminates, wherein elastic material may be stretched and joined with either or both first and second substrates. First spools are rotated to unwind first elastic strands from a first unwinder in a machine direction. The first elastic strands are positioned between the first substrate and the second substrate to form an elastomeric laminate. Before the first elastic strands are completely unwound from the rotating first spools, second spools are rotated to unwind second elastic strands from a second unwinder. Subsequently, the advancement of the first elastic strands from the first unwinder is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first spools to a subsequently utilized elastic material drawn from the second spools.

20190076304 · 2019-03-14 ·

The present invention includes disposable absorbent articles, such as disposable undergarment, diapers, other garments, and wound care dressings, having an elastomeric material disposed between two substrate layers and an absorbent core system that disposed on top of or between the two substrate layers. This invention may also include a disposable article having an elastomeric material disposed between two substrate layers without an absorbent core. The inclusion of an stretch adhesive in the construction of the article in various portions of the article (e.g., fastening tabs, front and/or rear sections, entire article, etc.) results in improved securement of the article to a wearer for reducing the risk of leakage and further improving comfort for the wearer. Furthermore, the inclusion of a stretch adhesive can provide a smooth contoured fit to a wearer, thereby improving appearance and self-confidence for the wearer.
