Methods and Apparatuses for Making Elastomeric Laminates with Elastic Strands Unwound from Spools on Surface Unwinders
20220257427 · 2022-08-18 ·

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.

Absorbent article with ear portion

An absorbent article includes a first waist region, a second waist region and a crotch region disposed between the first and second waist regions; and a chassis comprising a topsheet, a backsheet and an absorbent core disposed between the topsheet and the backsheet. The absorbent article also includes an ear disposed in one of the waist regions. The ear includes a laminate having a first nonwoven and a second nonwoven and an elastomeric material sandwiched between said first and second nonwovens in an elasticized region. The laminate also includes a first bonding region comprising a first plurality of ultrasonic bonds having a first bond density, and a second bonding region comprising a second plurality of ultrasonic bonds having a second bond density. The first bond density is greater than the second bond density.

Absorbent medical articles include a first absorbent layer with a radio opaque element located on the surface of the first absorbent layer. The radio opaque element has at least one segment that is non-linear and has at least one vertex, the vertex defines an angle of at least 15° and less than 165°. The radio opaque element may be a continuous or discontinuous element. The absorbent medical article may include additional absorbent layers. The radio opaque element makes the absorbent medical article detectable if left inside a patient.
