摘要:
An absorbent core comprising a front portion; a back portion; a middle portion positioned between the front portion and the back portion; and a longitudinal axis extending along a length of said core and crossing said front, middle and back portions, the absorbent core having a width extending perpendicular to said length and a perimeter comprising at least two opposing ends and at least two opposing sides positioned between said ends wherein the absorbent core comprises one or more channels having a first shape when the absorbent core is in dry state and a second shape when the absorbent core is in wet state and wherein said first and second shapes are different.

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.

An apparatus for manufacturing an absorbent body includes: a sheet supplying mechanism for supplying a sheet from a sheet roll; a crusher for crushing the sheet into a fibrous matter by scraping a reeling-out tip end of the reeled out sheet; and a fiber stacking device for forming the absorbent body in a predetermined shape by laminating the fibrous matter to be sent out from the crusher. When switching a supply of the sheet to the crusher from one to another sheet supplying mechanism, at least two sheet supplying mechanisms supply the sheet to the crusher over a predetermined period including a period in which the one sheet supplying mechanism decreases a sheet reeling-out speed, in correspondence with the period in which the one sheet supplying mechanism decreases the sheet reeling-out speed, the other sheet supplying mechanism increases a sheet reeling-out speed.

摘要:
A method of making a printed, elastic laminate has the steps of printing a motif on a longitudinally elongated elastic film. The printed elastic film is cut into longitudinally extending strips that are then bonded transversely next to each other between two surface webs through at least one of which the motif is visible to form a laminate. The laminate is then transversely stretched at least at the strips.
摘要:
A method of making an absorbent pad, and the absorbent pad so made, including a porous under layer and an absorbent body including a pulverized pulp and a super-absorbent materials bonded to and between the porous layers; characterized in that the absorbent body is applied between the porous layers before bonding thereto by: applying a first layer of pulverized pulp to the porous under layer; applying a layer of the super-absorbent material over the first layer of pulverized pulp; and applying a second layer of the pulverized pulp over the super-absorbent material layers. One or more of the above layers also includes a deodorizer material which may include a deodorizer agent, to reduce odors, an anti-inflammatory agent to prevent skin erythema, and/or a perfume fragrance.

A method for forming an absorbent structure is provided wherein absorbent members are adjacently disposed and orientated such as to have a specifically desired ratio of horizontal width to vertical height.
摘要:
A process for manufacturing a continuous web-like intermediate absorbent product including the steps of depositing onto a web-like supporting sheet a predetermined pattern of absorbent material. Bonding the deposited absorbent material to the supporting sheet by means of heat. Depositing longitudinal strips of an adhesive material onto the web-like sheet. Applying at least a further web-like sheet over the assembly, which joins the further sheet to the former in correspondence of the adhesive strips by compression. Longitudinally slitting the web-like composite assembly obtained and separately winding into rolls the narrower webs obtained, which include adjacent absorbent cores.
摘要:
An absorbent dressing comprising, a transparent backing sheet having a relatively high water vapor permeability, a front sheet having a pressure sensitive adhesive on a front surface thereof for facing a wound with the front sheet and adhesive having a plurality of apertures extending therethrough, and an absorbent layer intermediate the front sheet and backing sheet having a plurality of openings in register with the apertures of the front sheet, with the openings of the layer being at least as large as the apertures of the front sheet.
摘要:
An absorbent core comprising substantially continuous zones of one or more high fluid distribution structures and discontinuous zones of fluid absorption structures surrounding the one or more high fluid distribution structures, wherein the one or more high fluid distribution structures are arranged to distribute fluid across the absorbent core at a speed that is faster than the speed of fluid distribution across the absorbent core by said discontinuous fluid absorption structures, and wherein said continuous zones extend along a path that is substantially parallel to at least a portion of the perimeter of the core, said portion of the perimeter of the core comprising at least a portion of the sides of the core and one of the ends of the core.
