11737505 · 2023-08-29 ·

Proposed is an apparatus for manufacturing a hair cap. A rubber band mounting unit is formed on one side of the top surface of the workbench. A rubber band conveying unit is formed on the top surface of the workbench and grips the expanded rubber band. A nonwoven fabric cutting unit is formed on the other side of the top surface of the workbench to cut a nonwoven fabric. A nonwoven fabric fusing unit couples the rubber band, conveyed by the rubber band conveying unit, to the nonwoven fabric. A driving unit makes the rubber band conveying unit reciprocate to the rubber band mounting unit or the nonwoven fabric fusing unit. A collecting unit grips and collects the fused hair cap. Processes for placing the rubber band on the peripheral edge of the nonwoven fabric and bonding same are performed rapidly in succession.

THERMOPLASTIC NON-WOVEN TEXTILE ELEMENTS
20230265589 · 2023-08-24 ·

A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.

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.

Ultrasonic welding is performed by passing a first sheet layer, a second sheet layer, and an elastic film interposed therebetween in a stretched state in a machine direction between an anvil roll having a large number of protrusions and an ultrasonic horn. The anvil roll includes a region having the protrusions and in the region. A site, in which welding is performed by one ultrasonic horn, has a portion in which an area rate of the protrusions changes in a roll circumferential direction and a roll length direction. A difference between a maximum value and a minimum value in a change of the area rate of the protrusions in the roll circumferential direction is 4.5% or less, and a difference between a maximum value and a minimum value in a change of the area rate of the protrusions in the roll length direction is 1.5% or less.

Disposable wearable article
11730637 · 2023-08-22 · ·

A disposable wearable article includes an elastic film stretchable structure in which an elastic film is laminated between a first sheet layer and a second sheet layer. The first sheet layer and the second sheet layer are bonded to each other through holes passing through the elastic film with many bonded portions arranged at intervals. A region having the elastic film stretchable structure includes a stretchable region that elastically stretches and contracts together with the elastic film. The stretchable region includes a plurality of elastic films disposed so as to have an overlapping portion. The number of laminated layers of the elastic film in a region located in an intermediate portion of the stretchable region in an orthogonal direction (XD) orthogonal to a stretchable direction (ED) is different from that in each of second regions adjacent to both sides of the first region.
