Absorbent core with absorbent material pattern
A substantially planar absorbent core (28) extending in a transversal direction (x) and a longitudinal direction (y), and comprising a core wrap (16, 16′) enclosing an absorbent material (60) substantially free of cellulose fibers, the absorbent material forming a pattern of discrete absorbent material areas. The pattern comprises transversally-orientated areas (752) and longitudinally-orientated areas (754). The absorbent core may further comprise at least two longitudinally-orientated channel-forming areas (26).
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 methods for assembling elastic laminates that may be used to make absorbent article components. Particular aspects of the present disclosure involve providing a first substrate and a second substrate, the first substrate and the second substrate, each having a width in a cross direction; providing an activated elastic material; elongating the activated elastic material; and ultrasonically bonding the first substrate together with the second substrate with the elongated activated elastic material positioned between the first substrate and the second substrate.
Method for producing absorber and method for producing absorbent article
An absorbent member manufacturing method of the present invention is a method for manufacturing an absorbent member (100) for an absorbent article and including synthetic fibers (10b) and hydrophilic fibers (10a). The method involves: a transporting step of transporting the hydrophilic fibers (10a) and a plurality of sheet fragments (10bh) to an accumulating depression (41) by using a duct (3); an accumulating step of accumulating, in the accumulating depression (41), the plurality of sheet fragments (10bh) and the hydrophilic fibers (10a), and obtaining an accumulation (100a) which is a constituent member of the absorbent member (100); and a depression forming step of forming a depression (100e) in the accumulation (100a) by applying pressure to a portion thereof. In the transporting step, the sheet fragments (10bh) and the hydrophilic fibers (10a) are brought into contact with one another in an airflow created inside the duct (3), and the sheet fragments (10bh) and the hydrophilic fibers (10a) are transported by the airflow in a dispersed and airborne state in which the sheet fragments and the hydrophilic fibers are mixed.
