METHODS AND APPARATUSES FOR MAKING ELASTOMERIC LAMINATES WITH ELASTIC STRANDS
20220000676 · 2022-01-06 ·

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. In particular, discrete mechanical bonds are applied to a first substrate and a second substrate to secure elastic strands therebetween, wherein the discrete bonds are arranged intermittently along the machine direction. During the bonding process, heat and pressure are applied to the first substrate and the second substrate such that malleable materials of the first and second substrates deform to completely surround an outer perimeter of a discrete length of the stretched elastic strand. After removing the heat and pressure from the first and second substrates, the malleable materials harden to define a bond conforming with a cross sectional shape defined by the outer perimeter of the stretched elastic strand.

Indirect printing of AGM

The present invention relates to a method of applying absorbent gelling material (AGM) granules by indirect printing onto an carrier layer for use in an absorbent article, particularly diaper for babies or adults, training pants, pull-up diapers (diaper pants), sanitary napkins, panty liners or the like. These articles typically comprise the carrier layer with the AGM particles together with further layers, making up the complete article.

All solid-state battery, resin applicator, and method for producing all solid-state battery

A solid-state battery includes a third active material layer, a first solid electrolyte layer, a first active material layer, a first current collector layer, a second active material layer, a second solid electrolyte layer and a fourth active material layer in the order mentioned, wherein both the first and second active layers are anode or cathode active material layers. When both the first and second active layers are anode layers, both the third and fourth active layers are cathode layers. When both the first and second active layers are cathode layers, both the third and fourth active layers are anode layers, at least the first current collector layer extends to an outer side than the third and fourth active layers, and an insulating resin layer continuously across a surface of the extending part on one side, a side face and a surface of the extending part on the other side.

Laminate(s) comprising beamed elastics and absorbent article(s) comprising said laminate(s)

The present disclosure relates to one or a combination of an absorbent article's chassis, inner leg cuffs, outer leg cuffs, ear panels, side panels, waistbands, and belts that may comprise one or more pluralities of tightly spaced (less than 4 mm, less than 3 mm, less than 2 mm, and less than 1 mm) and/or very fine (less than 300, less than 200, less than 100 dtex) and/or low strain (less than 300%, less than 200%, less than 100%) elastics to deliver low pressure less than 1 psi (according to the conditions defined by the Pressure-Under-Strand method below) under the elastics, while providing adequate modulus of (between about 2 gf/mm and 15 gf/mm) to make the article easy to apply and to comfortably maintain the article in place on the wearer, even with a loaded core (holding at least 50 mls of liquid), to provide for the advantages described above.

Methods and apparatuses for making elastomeric laminates with elastic strands provided with a spin finish

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. The elastomeric laminates may include a first substrate, a second substrate, and an elastic material located between the first and second substrates. During assembly of an elastomeric laminate, a beam is rotated to unwind the elastic strands from the beam, wherein the strands may include a spin finish. First bonds are applied to bond discrete lengths of the stretched elastic strands with and between the first substrate and the second substrate, wherein the discrete first bonds are arranged intermittently along the machine direction. In addition, second bonds are applied between consecutive first bonds to bond the first and second substrates directly to each other, wherein the second bonds extend in the machine direction and may be separated from each other in a cross direction by at least one elastic strand.
