Absorbent Articles With Corrugated Elastomeric Laminates and Methods for Making Corrugated Elastomeric Laminates

U.S. Patent No. 12,616,614


Filed: 5/19/23
Issued: 5/5/26

A method for making an elastomeric laminate, the method comprising steps of: providing a first corrugated substrate by forming ridges that alternate with depressions along a machine direction in a first substrate; providing a second corrugated substrate by forming ridges that alternate with depressions along the machine direction in a second substrate; advancing elastic strands in the machine direction; stretching the elastic strands in the machine direction; subsequent to the step of stretching the elastic strands, applying a first adhesive intermittently to the elastic strands to form discrete regions of the first adhesive on the elastic strands; bonding discrete lengths of the elastic strands with and between the first corrugated substrate and the second corrugated substrate with first bonds formed with the discrete regions of the first adhesive; and bonding the depressions of the first corrugated substrate directly with the depressions of the second corrugated substrate with second bonds along the machine direction between consecutive first bonds.
