Abstract
The present disclosure relates to absorbent articles including elastic laminates and to methods and apparatuses for making absorbent articles having elastic laminates in front and/or back waist regions with frangible pathways.
Claims17
A method for assembling absorbent articles, the method comprising steps of:
- providing an elastic laminate, the elastic laminate comprising inner waist elastic strands and outer waist elastic strands positioned between and connected with a first substrate and a second substrate, the inner and outer waist elastic strands extending in a machine direction, the elastic laminate further comprising a first edge separated from a second edge in a cross direction, wherein the elastic laminate comprises a first laminate width defined by a distance extending in the cross direction between the first edge and the second edge, and wherein the inner waist elastic strands are intermittently bonded with the first substrate and the second substrate along the machine direction to form an unbonded region where the inner waist elastic strands are not bonded with the first substrate and the second substrate;
- advancing the elastic laminate in the machine direction;
- forming a first low-stretch zone by severing at least one first inner waist elastic strand in the unbonded region such that the at least one first inner waist elastic strand retracts within the unbonded region;
- bonding a fastener component to the second substrate in the first low-stretch zone;
- subsequent to bonding the fastener component, forming a second low-stretch zone by severing at least one second inner waist elastic strand in the unbonded region such that the at least one second inner waist elastic strand retracts within the unbonded region;
- and
- subsequent to bonding the fastener component, forming a first frangible pathway extending in the cross direction, the first frangible pathway comprising lines of weakness, wherein inner and outer waist elastic strands intersected by the first frangible pathway are severed at the lines of weakness.

- after severed inner waist elastic strands retract, bonding a fastener component to the first substrate in the low-stretch zone;
- and
- subsequent to bonding the fastener component, forming a frangible pathway extending in the cross direction, the frangible pathway comprising lines of weakness, wherein inner and outer waist elastic strands intersected by the frangible pathway are severed at the lines of weakness.
