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.

Absorbent articles comprising a multilayer outer cover comprising a first outer layer and a second outer layer comprising a component that exhibits at least partial elastic recovery after mechanical activation in the machine direction; an inner layer, disposed between the first outer layer and the second outer layer, the inner layer comprising elastic strands; and wherein at least one of the first outer layer and second outer layer is laminated to the inner layer.

Methods and structures are disclosed. An example method includes: rotating a tubular mandrel about a longitudinal axis of the tubular mandrel; depositing a composite material on an inner surface of the tubular mandrel to form a composite tubular member on the inner surface of the tubular mandrel; inserting and expanding an inner expandable mandrel within the composite tubular member to cause the inner expandable mandrel to press the composite tubular member against the inner surface of the tubular mandrel; curing the composite tubular member; removing the inner expandable mandrel; placing a frame within the composite tubular member; and removing the tubular mandrel so as to obtain the composite tubular member with the frame placed therein.

A sealing machine is provided for sealing a sealing material by heating a fin of the sealing material wrapped around a product. The sealing machine comprises, in a transport direction of the sealing material, a pair of tracking rollers for tensioning the sealing material and a pair of heating rollers for sealing the sealing material by applying heat to the fin when the fin is moved between the pair of heating rollers. Furthermore, the pair of tracking rollers and the pair of heating rollers are configured to be driven independently.

A device (10) for sealing three-dimensional objects (16) in the bag opening (14) of a film bag (12) comprises a clamp (36, 38) for the film bag (12), which has a pair of clamping shoes (42, 44) on each side, between which the edge of the film bag (12) is held. A heat sealer (26, 28) is provided for sealing the three-dimensional object (16) in the bag opening (14) of the film bag (12), wherein the heat sealer (26, 28) has a pair of sealing jaws (26, 28) between which the bag opening (14) of the film bag (12) can be sealed. The two clamping shoe pairs (42, 44) of the clamp (36, 38) are moved apart from one another during the sealing process.

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.

A fusion welding device, comprising a fusion welding work motor, a fusion welding work moving assembly, and a fusion welding work fixed assembly, the fusion welding work motor being connected to the fusion welding work moving assembly by means of a transmission mechanism. The fusion welding device is provided with a central connection component that is able to rotate, and the central connection component is provided with a first input position, a second input position, and a locking structure connection position. The present fusion welding device is able to implement automatic band pressing and fusion welding work by means of relatively simple structural cooperation, and by means of differently transmitted front and back connections and changes in engagement, and is able to automatically lift the fusion welding work moving assembly without requiring a handle or related operations.

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.

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. The methods and apparatuses may be configured with a plurality of elastic strands wound onto a beam, wherein one or more elastic strands comprises a spin finish. During assembly of an elastomeric laminate, the beam is rotated to unwind the elastic strands from the beam. A portion of the spin finish may be removed from the advancing elastic strand with a spin finish removal apparatus. The spin finish removal apparatus may be configured to apply detergent to an advancing elastic strand and may also wipe and/or dry the advancing elastic strand. The treated stretched elastic strand may then be connected between a first substrate and a second substrate. In some configurations, adhesive may be applied to the treated the elastic strand, the first substrate, and/or the second substrate.

The present invention relates to a process for the formation of a structured film, a structured film as such, an article comprising the structured film, a device for the continuous formation of such a structured film and a composite comprising the structured film.
