Method and apparatus for assembling absorbent articles

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.

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.

Method and apparatus for assembling absorbent articles

The present disclosure relates to apparatuses and methods for assembling elastic laminates that may be used to make absorbent article components. Particular aspects of the present disclosure involve an anvil and a spreader mechanism adjacent the anvil. During the assembly process, a first substrate may be advanced in a machine direction onto the rotating anvil. The spreader mechanism operates to activate an elastic material by stretching the elastic material in the cross direction to a first elongation. The elastic material is then consolidated to a second elongation in the cross direction, wherein the second the elongation is less than the first elongation. The consolidated elastic material is then bonded between a first substrate and a second substrate on the anvil. In some configurations, the first and second substrates may be nonwovens, and the elastic material may be an elastic film and/or an elastic laminate.

ELASTIC COMPOSITE FOR HAVING CROSS-DIRECTIONAL ELASTICITY AND A SYSTEM AND METHOD FOR MAKING THE ELASTIC COMPOSITE

A method of making an elastic composite is described that entails conveying a first sheet of material on a conveyor, and wrapping a section of elastic about the first sheet and the conveyor, thereby applying elastics cross directionally across the first sheets. A second sheet of material is applied onto the first sheet having elastics applied thereon, thereby creating a subcomposite including the first sheet, the second sheet, and elastics sandwiched therebetween, wherein a plurality of elastics extend outward from the one side of the subcomposite, about the conveyor, and return into an opposite side of the subcomposite. The sub-composite is cut through the first and second sheets and the elastics, thereby separating the sub-composite into a first carrier and a second carrier, each carrier including a first material layer and a second material layer, whereby a plurality of spaced apart elastic elements extend from the first carrier to the second carrier, the first and second carriers defining an exposed elastic region therebetween formed by the plurality of spaced apart elastic elements.
