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

The methods herein relate to assembling an elastic laminate with a first elastic material and a second elastic material bonded between first and second substrates. During assembly, an elastic laminate may be formed by positioning the first and second substrates in contact with stretched central regions of the first and second elastic materials. The elastic laminates may include two or more bonding regions that may be defined by the various layers or components of the elastic laminate that are laminated or stacked relative to each other. In some configurations, a first plurality of ultrasonic bonds are applied to the elastic laminate to define a first bond density in the first bonding region, and a second plurality of ultrasonic bonds are applied to the elastic laminate to define a second bond density in the second bonding region, wherein the second bond density is not equal to the first bond density.

20210307970 · 2021-10-07 ·

The present disclosure relates to assembling elastic laminates that may be used to make absorbent article components. Methods herein may include an anvil adapted to rotate about an axis of rotation, wherein first and second spreader mechanisms adjacent the anvil roll are axially and angularly displaced from each other with respect to the axis of rotation. During the assembly process, a substrate may be advanced in a machine direction onto the rotating anvil. The first spreader mechanism stretches a first elastic material in the cross direction, and the second spreader mechanism stretches a second elastic material in the cross direction. The stretched first and second elastic materials advance from the spreader mechanisms and onto the substrate on the anvil roll. The combined and elastic materials may then be ultrasonically bonded together on the anvil to form at least one elastic laminate.

METHOD AND SYSTEM FOR FABRICATING AN ELASTIC NONWOVEN MATERIAL

A method and system for fabricating an article using a first bonding module having a first bonding module face and a second bonding module having a second bonding module face include supplying a first non-woven fabric to at least one of the first bonding module face and the second bonding module face, and supplying a plurality of elastic strands to a surface of the first non-woven fabric. The method and system further include entrapping a first elastic strand between a first pair of adjacent bonds in a first row in the first non-woven fabric, entrapping a second elastic strand between a second pair of adjacent bonds in the first row, and creating a third pair of adjacent bonds in the first row free of elastic bands therebetween. The third pair of adjacent bonds is located between the first pair of adjacent bonds and the second pair of adjacent bonds.
