A method for alignment of a pattern printed on a material for an absorbent article by a rotary printing device, including providing a first composition from a first chamber; providing a second composition including a detectable agent from a second chamber; wherein the first composition from the first chamber and the second composition from the second chamber are supplied to the same anilox roller or directly to the same rotary printing cylinder; and printing the first and second compositions on the material for an absorbent article by a rotary printing cylinder.

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.

Absorbent garments are made by applying a refastenable material to a continuous panel web, folding the panel web, cutting the folded panel web into discrete folded panels, and aligning the folded panels with perforations in a continuous elasticized waist web. Discrete folded patches are coupled to the elastic web via the refastenable material and the perforation cuts are broken to form a continuous waistband. Absorbent cores are coupled between the continuous waistband and a second continuous waistband, which are cut to form the absorbent garments. The manufacturing apparatus includes a perforation cutter that forms perforation cuts in a continuous waist web comprising elastic elements positioned between facing web layers, a panel applicator that cuts a folded panel web into discrete panels and attaches the discrete panels to the waist web about the perforation cut. A breakage system separates the waist web at the perforation cuts and unfolds the discrete panels.

A method for producing pant-like absorbent sanitary articles, wherein a plurality of absorbent bodies are attached to a single continuous elastic band, which is cut to form a plurality of absorbent sanitary articles in an outspread configuration, which are then folded in a closed pant-like configuration.

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.

Pulpless absorbent cores and methods of manufacture are disclosed. A method of forming an absorbent core may comprise moving a forming surface in a machine direction, creating a pressure differential across the forming surface, advancing a base carrier sheet on the forming surface in the machine direction, applying a first adhesive onto the base carrier sheet, and applying a first quantity of particulate material onto the first adhesive at a first cross-machine direction width. The method may further comprise depositing a matrix of material onto the first quantity of particulate material at a second cross-machine direction width, the matrix of material comprising a second quantity of particulate material and a second adhesive, wherein the second cross-machine direction width is smaller than the first cross-machine direction width, and wherein the second quantity of particulate material and the adhesive are pre-mixed prior to deposition onto the first quantity of particulate material.

A system for removing and donning a disposable absorbent article by using a separate robotic device includes an absorbent assembly having an inner layer that partly defines a body-facing surface, an outer layer that defines a garment-facing surface, and an absorbent body disposed between the inner and outer layers. The absorbent assembly also includes a pair of ears extending transversely outward from the opposite sides of the absorbent assembly in the back waist region, each of the ears including a body-facing surface with a primary first fastening-component that is selectively engageable with a primary second fastening-component in the front waist region of the absorbent assembly in a wear configuration of the article, and a garment-facing surface opposite the body-facing surface. The absorbent article also includes a manipulation-enablement feature configured to assist the post-retail manipulation of the absorbent article by the robotic device.

A carrying device includes: a carrying section having a receiving surface to be in contact with a first sheet material that is continuous in a carrying direction, wherein one edge of the first sheet material is wave-shaped, the carrying section defining an inclined slit portion, wherein the inclined slit portion defines an opening on the receiving surface, wherein the inclined slit portion extends in an inclined direction so as to be displaced from a proximal side toward a distal side of a protruding portion while extending downstream in the direction of carrying the first sheet material, and wherein the inclined slit portion sucks the protruding portion along the wave-shaped edge; and a box defining a suction space that keeps the inclined slit portion under a negative pressure so that the protruding portion is pulled into the inclined slit portion by suction.

A method including: a step of carrying first and second continuous webs in a carrying direction; a step of folding the continuous webs in two; a first attachment step, in which portions of first edges, which extend in the carrying direction of the continuous webs and which are to be leg holes of a worn article, are attached together intermittently in the carrying direction; a step of straightening, in a width direction, creases on one of the continuous web after the first attachment step; and a second attachment step, in which the continuous webs are attached together at least at portions along second edges opposite to the first edges, with the creases being straightened.
