    摘要： Described herein is a multiple layer absorbent core having a front ear section, a crotch section and a back ear section, wherein the machine direction length of the crotch section equals the combined machine direction length of the front ear section and the back ear section, the angle and radii forming the transition from the crotch width to the ear width being equal, the core being suitable for use in an absorbent article, and a method for manufacturing such multiple layer absorbent core. The method comprises providing a single web of absorbent core material from a roll, in which the web having parallel straight longitudinal side edges; continuously transporting the web of absorbent core material in the machine direction; continuously cutting the web of absorbent core material longitudinally into web sections having at least one full-pattern strip having a repeating hourglass-shape and first and second side trim pieces each of the side trim pieces having a straight edge defined by one of the parallel straight longitudinal side edges of the web and an opposite non-linear longitudinal edge having a pattern corresponding to one of the longitudinal edges of the full-pattern strip; continuously orienting the side trim pieces relative to the full-pattern strip such that the ear sections and said crotch section of the side trim pieces are superimposed in registration with said full-pattern strip to form a continuous multiple layer composite strip; and successively cutting the composite strip in the transverse direction at predetermined intervals to form discrete multiple layer absorbent cores.

    摘要： The present invention provides a stable material having enhanced extensibility and a method for making the same. A tensioning force is applied to the neckable material to neck the material in a direction perpendicular to the first direction. The necked material is then subjected to mechanical stabilization to provide a stabilized extensible necked material. The stabilized extensible necked material is then passed between the peripheral surface of a cylinder which is driven in rotating motion and a device for pressing the stabilized extensible necked material against the peripheral surface of the cylinder. A retarding member retards the passage of the stabilized extensible necked material and directs the material away from the peripheral surface of the cylinder. The stabilized extensible necked material is easily extended in a direction parallel to the first direction and perpendicular to the first direction.

    摘要： The present invention pertains, in a preferred embodiment, to a method for selectively aperturing a nonwoven web exhibiting a plurality of surface energy gradients. The method includes the steps of: providing a nonwoven web of fibers exhibiting a surface energy, the nonwoven web having a first surface, a second surface and a plurality of fluid passageways placing the first and second surfaces in fluid communication with one another; applying a surface treatment to the first surface of the nonwoven web, the surface treatment having a surface energy less than the surface energy of the fibers of the nonwoven web creating a plurality of surface energy gradients defined by discontinuous, spaced regions which are adapted to exert a force on a fluid contacting the first surface, such that the fluid will be directed toward the fluid passageways for transportation away from the first surface and in the direction of the second surface; weakening the nonwoven web at a plurality of locations creating a plurality of weakened, melt-stabilized locations; and applying a tensioning force to the nonwoven web to cause the nonwoven web to rupture at the plurality of weakened, melt-stabilized locations creating a plurality of apertures in the nonwoven web coincident with the plurality of weakened, melt-stabilized locations. The web is particularly well suited for use as a topsheet on a disposable absorbent article.

    摘要： A pump dispenser for fluent products is disclosed as inluding a container for housing the fluent product, dispensing outlet means on the container, a follower piston closing the lower end of the container below the product, and means for varying the volume within such dispenser. The volume varying means comprises a plunger adapted to be reciprocated within the dispenser to alternately decrease the volume therewithin and, following such decrease, return to its original position thereby increasing the volume within the dispenser. The plunger further comprises a peripheral skirt having predetermined outer lateral dimensions at its lower distal end, and an enlarged attachment head on such lower distal end. The attachment head has predetermined outer lateral dimensions which are larger than the outer lateral dimensions of such lower distal end therey effectively forming a reentrant portion on the plunger above the enlarged head. A flexible thin-walled diaphragm adapted to isolate and seal the volume reducing means from the fluent product is connected about its outer periphery to the dispenser. The diaphragm further has a central portion substantially conforming to the enlarged attachment head and reentrant portion of the plunger thereby effectively locking the diaphragm to the plunger and its attachment head. The attached diaphragm is thereby adapted to provide a substantially frictionless seal between the reciprocable plunger and the fluent product. The unique structure and combination of the plunger and flexible diaphragm of the subject pump dispenser provides for ease of manufacturing and handling of such pump dispenser subassembly.

    摘要： An improved method and apparatus for incrementally stretching "zero strain" stretch laminate webs to impart elasticity thereto in the direction of initial stretching, at least up to the point of initial stretching. The "zero strain" stretch laminate material is formed of at least two plies of material which are either intermittently or substantially continuously secured to one another along at least a portion of their coextensive surfaces while in a substantially untensioned ("zero strain") condition. One of the plies is stretchable and elastomeric, while the second ply is elongatable, but not necessarily elastomeric. The second ply will, upon stretching of the laminate, be at least to a degree permanently elongated so that, upon release of the applied tensile forces, it will not return to its original undistorted configuration. This results in z-direction bulking of the laminate web when the applied tension is released as well as subsequent elastic extensibility in the direction of initial stretching, at least up to the point of initial stretching. In a particularly preferred embodiment of the present invention the opposed peripheral edge portions of the laminate web to be incrementally stretched are subjected to restraint to substantially prevent inwardly directed slippage or contraction thereof in a direction parallel to the direction of stretching. This maximizes the effectiveness of the incremental web stretching operation by forcing the "zero strain" stretch laminate web to undergo the fullest possible degree of elongation during the incremental stretching operation.

    摘要翻译： 一种改进的方法和装置，用于递增地拉伸“零应变”拉伸层压纤维网，以在初始拉伸的方向上赋予弹性，至少直到初始拉伸。 “零应变”拉伸层压材料由至少两层材料形成，它们在基本上未张紧（“零应变”）条件下，沿其共同延伸表面的至少一部分间断地或基本上连续固定。 其中一层是可拉伸和弹性的，而第二层是可伸长的，但不一定是弹性的。 第二层将在拉伸层压体时至少达到一定程度的永久拉长，使得在释放所施加的拉伸力时，其将不会返回到其原始的未失真构型。 这导致当施加的张力释放时层压纤维网的z方向膨胀以及在初始拉伸方向上的随后的弹性延展性，至少直到初始拉伸。 在本发明的一个特别优选的实施例中，要逐渐拉伸的层压纤维网的相对的周边边缘部分受到约束，以基本上防止沿着与拉伸方向平行的方向向内的滑动或收缩。 通过迫使“零应变”拉伸层压纤维网在增量拉伸操作期间经历最大可能的伸长程度，使增量幅材拉伸操作的效果最大化。
