Apertures formed in the precursor web material have a length and width exhibiting a minimal aspect ratio.

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.

Methods and apparatuses for making elastomeric laminates

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. Aspects of the methods for assembling elastomeric laminates may utilize elastic strands supplied from beams that may be joined with first and second substrates, and may be configured to carry out various types of operations, such as bonding and splicing operations.
