Abstract
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.
Claims9
A method for making absorbent articles, the method comprising steps of:
- providing first elastic strands wound onto a beam, wherein the first elastic strands comprise a first decitex;
- rotating the beam to unwind the first elastic strands from the beam;
- advancing the first elastic strands from the rotating beam;
- stretching the first elastic strands;
- and
- providing second elastic strands, wherein the second elastic strands comprise a second decitex, and wherein the second decitex is greater than the first decitex;
- unwinding the second elastic strands from an overend unwinding device;
- stretching the second elastic strands;
- bonding the stretched first and second elastic strands between a first substrate and a second substrate to form an elastomeric laminate comprising different stretch characteristics in different regions in the elastomeric laminate, wherein the first elastic strands are bonded with a first bond applicator configured to apply adhesive or mechanical bonds and wherein the second elastic strands are bonded with a second bond applicator configured to apply adhesive bonds;
- and
- cutting the first elastic strands to create deactivated regions in the elastomeric laminate.
