A method and apparatus for producing elastic laminates, wherein a first continuous elastic film is stretched in a transverse direction by a spreader device and is applied on a transfer wheel on which it is cut longitudinally to form at least two parallel continuous elastic films which are transferred on a non-woven web held on the an outer cylindrical surface of an anvil wheel.

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 for manufacturing composite sheet

Provided are a composite sheet whose recess-protrusion shape can easily be made crush-resistant in a state that the soft feel against the skin is maintained, and a device and method for manufacturing said composite sheet. A first sheet has a curved part in which one surface thereof rises and the other surface thereof is recessed, and a boundary part adjacent to the curved part. A second sheet is joined to the boundary part of the first sheet so as to cover the other surface of the curved part. A region of the second sheet facing the curved part has a protruding part in which an inside surface on the first sheet side rises so as to approach the curved part and an outside surface on the reverse side thereof is recessed, and a flat part surrounding the periphery of the protruding part.

Methods and apparatuses for making absorbent articles having contoured belts

The present disclosure relates to methods and apparatuses for assembling disposable pant diapers having contoured elastic belts. During the assembly process, opposing end regions of chassis are connected with the elastic belts in the form of first and second continuous elastic laminates. The chassis are then folded to place the elastic laminates into a facing relationship. The inner longitudinal edges of one or both the elastic laminates are then cut to define a contoured shape. Discrete pieces of trim material may be removed from one or both the elastic laminates, and the first and second continuous elastic laminates are cut in the cross direction to form discrete pant diapers. In some configurations, a single knife both removes the trim material and cuts the elastic laminates in cross direction. And in some configurations, a first knife removes the trim material and a second knife cuts the elastic laminates in cross direction.

ABSORBENT CORE WITH PROFILED DISTRIBUTION OF ABSORBENT MATERIAL

An absorbent core for absorbent articles such as diapers. The core comprises a core wrap comprising a top side and a bottom side, an absorbent material between the top side and the bottom side, a first and second longitudinally-extending channel-forming areas disposed on opposite sides of the longitudinal axis and substantially free of absorbent material preferably through which the top side of the core wrap is attached to the bottom side of the core wrap. The core has a central absorbent zone between the first and the second channel-forming areas and a first and second lateral absorbent zones disposed laterally outwardly. The average basis weight of the absorbent material in the central absorbent zone is lower than the average basis weight of the absorbent material in the lateral absorbent zones.

ABSORBENT CORE WITH TRANSVERSAL FOLDING LINES

An absorbent core for absorbent articles such as diapers comprising a core wrap comprising a top side and a bottom side, an absorbent material between the top side and the bottom side of the core wrap, a first and second longitudinally-extending channel-forming areas substantially free of absorbent material preferably through which the top side of the core wrap is attached to the bottom side of the core wrap disposed on opposite sides of the longitudinal axis. The core has a central absorbent zone between the first and the second channel-forming areas and a first and second lateral absorbent zones disposed laterally outwardly. The absorbent core comprises at least one transversal folding line, preferably at least two transversal folding lines, in the region where the longitudinally-extending channel-forming areas are present.

Odour control material, method for preparation of an odour control material and an absorbent product comprising the odour control material

The present invention relates to an odor control material consisting of a water-insoluble particulate odor control agent and a thermoplastic water-soluble carrier matrix encapsulating the odor control agent. The carrier matrix dissolves when in contact with an aqueous solution, such as urine and the odor control material is obtained by means of thermoforming. The invention relates also to a method for the preparation of the odor control material and the use of the odor control material in absorbent products. The present odor control material minimizes dusting problems caused by particulate odor control agents in production processes.

Method and apparatus for flexibly assembling packages of absorbent articles

Apparatuses and methods herein may be configured to utilize existing high speed assembly lines with dedicated packaging apparatuses to assemble various kinds of packages of absorbent articles. Absorbent articles advancing from an assembly line are diverted before reaching a dedicated packaging apparatus. The diverted absorbent articles are transported to a selectable packaging apparatus to be placed in containers containing desired quantities and/or types of absorbent articles to create select packages. Carriers are movably connected with a track, wherein a linear synchronous motor independently moves the carriers along the track. Diverted absorbent articles are transferred to a carrier in a receiving zone, and the diverted absorbent articles are moved along the track from the receiving zone to a drop off zone. The diverted absorbent articles are then transferred from the carrier in the drop off zone to a selectable packaging apparatus.
