Methods and apparatuses for assembling elastic laminates with different bond densities for absorbent articles

A method for assembling elastic laminates, the method comprising steps of:

• providing a first substrate and a second substrate, the first substrate and the second substrate each comprising a first surface and an opposing second surface, a first longitudinal edge and a second longitudinal edge separated from the first longitudinal edge to define a width in a cross direction;
• wrapping the first surface of the first substrate onto an outer circumferential surface of an anvil roll;
• providing an elastic film, the elastic film comprising a first edge region and a second edge region separated from the first edge region in the cross direction by a central region;
• stretching the central region of the elastic film in the cross direction;
• advancing the elastic film onto the anvil roll, wherein the stretched central region of the elastic film is positioned in contact with the second surface of the first substrate;
• forming an elastic laminate by advancing the second substrate in a machine direction onto the anvil roll to position the first surface of the second substrate in direct contact with the stretched central region of the elastic film, wherein the elastic laminate comprises a first bonding region and a second bonding region, wherein the first bonding region is defined where the stretched central region of the elastic film is in direct contact with the second surface of the first substrate and the first surface of the second substrate, and wherein the second bonding region is positioned completely outside the first bonding region;
• and
• applying a first plurality of bonds to the elastic laminate to define a first bond density in the first bonding region;
• and
• applying a second plurality of bonds to the elastic laminate to define a second bond density in the second bonding region, wherein the first bond density is not equal to the second bond density, or wherein the first bond density is equal to the second bond density and wherein at least one of the first plurality of bonds comprises a shape that is different from a shape of at least one of the second plurality of bonds.
