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.
Claims8
A method for making elastomeric laminates, the method comprising steps of:
- rotating a pattern roll about an axis of rotation extending axially in a cross direction, the pattern roll comprising pattern elements extending radially outward from the axis of rotation;
- providing a first roller and a second roller adjacent the first roller to define a nip between the first roller and the second roller;
- advancing a first substrate and a second substrate through in a machine direction through the nip at a first speed S1 of at least about 100 meters per minute;
- providing mandrel cores with at least one elastic strand wound onto each mandrel core;
- unwinding elastic strands from the mandrel cores;
- advancing the elastic strands from the mandrel cores;
- stretching the elastic strands;
- applying adhesive to at least one of the elastic strands, the first substrate, and the second substrate;
- advancing the stretched elastic strands between the first substrate and the second substrate at the nip to form an elastomeric laminate;
- providing a pressing surface adjacent the pattern roll to define a second nip between the pattern roll and the pressing surface, wherein the pressing surface comprises an energy transfer surface of an ultrasonic horn;
- and
- intermittently engaging the elastomeric laminate with the pattern elements on the pattern roll.
