Methods and apparatuses for making elastomeric laminates with elastic strands unwound from beams

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. A first beam is rotated to unwind a first plurality of elastic strands from the first beam in the machine direction. The first plurality of elastic strands are positioned between the first substrate and the second substrate to form the elastomeric laminate. Before the first plurality of elastic strands are completely unwound from the first beam, a second beam is rotated to unwind the second plurality of elastic strands from the second beam. Subsequently, the advancement of the first plurality of elastic strands from the first beam is discontinued. Thus, the elastomeric laminate assembly process may continue uninterrupted while switching from an initially utilized elastic material drawn from the first beam to a subsequently utilized elastic material drawn from the second beam.

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.

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.
