09789008 · 2017-10-17 · ·

Provided are a disposable diaper production method and a disposable diaper production device by which cutting positions of respective side pieces can be accurately managed. A partly-finished product is conveyed in a longitudinal direction in a state in which both side portions in the width direction of the cutting position of respective side panel pieces are held for each set of the two side panel pieces when the respective side panel pieces are cut off by a cutting unit. A controller controls driving rates of a cutting motor and a conveying motor to rotate driving blades at a rate faster than the conveying rate of the partly-finished product.

Indirect printing of AGM

The present invention relates to a method of applying absorbent gelling material (AGM) granules by indirect printing onto an carrier layer for use in an absorbent article, particularly diaper for babies or adults, training pants, pull-up diapers (diaper pants), sanitary napkins, panty liners or the like. These articles typically comprise the carrier layer with the AGM particles together with further layers, making up the complete article.

Apparatuses and methods for transferring and bonding substrates

A method for mechanically deforming, such as by bonding, a substrate assembly. The substrate assembly may be advanced at first velocity toward a bonder apparatus. The bonder apparatus may rotate at a second velocity, which is less than or equal to the first velocity. The bonder apparatus may include a support surface and a process assembly. The substrate assembly may be contracted prior to advancing onto the bonder apparatus. A first process assembly may receive a leading portion of the substrate assembly and a subsequent process assembly may receive a trailing portion. The leading portion and the trailing portion define a product arc length, which is less than or equal to a process product pitch. One or more processes may be performed on the substrate assembly. The substrate assembly may then be removed from the apparatus and advanced through a metering assembly such that the substrate assembly exits at the first velocity and may be expanded such that the leading portion and the trailing portion are separated by the process product pitch.

Apparatuses and methods for transferring and bonding substrates

A method for mechanically deforming a substrate assembly. The substrate assembly may advance at a first velocity toward a bonder apparatus. The bonder apparatus may rotate about an axis of rotation and include a support surface between a first member and a second member. The first and second members may rotate at the first velocity and may be separated by an initial angle. The first member may receive a leading portion and the second member may receive a trailing portion of the substrate assembly. The first member may decelerate to a second velocity, and, subsequently, the second member may decelerate to the second velocity. The first member and the second member may be separated by a process angle, which may be different than the initial angle. A central portion of the substrate assembly may be relaxed while the leading and trailing portion may be held at a process tension. The substrate assembly may then undergo one or more processes.

ABSORBENT ARTICLE WITH PARTIALLY ENCLOSED WAIST CONTAINMENT MEMBER AND METHOD OF MANUFACTURING THEREOF
20170246055 · 2017-08-31 ·

An absorbent article (10, 110) can include a waist containment member (54) with a first longitudinal side edge (72), a second longitudinal side edge (74), a proximal portion (76), an intermediate portion (77), and a distal portion (78). The proximal portion (76) can be coupled to the chassis (11) of the absorbent article (10, 110). The intermediate portion (77) can be free to move independent of the proximal portion (76) and the distal portion (78) and free to move independent of the body facing surface (19) of the chassis (11) to provide a containment pocket (82) for containing body exudates. The distal portion (78) can be disposed underneath the intermediate portion (77) when the absorbent article (10, 110) is in the stretched, laid-flat configuration. The waist containment member (54) can also include a first lateral tack-down region (83a) and a second lateral tack-down region (83b).

ABSORBENT ARTICLE WITH CHANNELS

A personal care absorbent article is disclosed which employs a combination of void spaces, also referred to as channels, in the crotch region of the article in conjunction with shaping elastic members located outside the lateral side edges of the absorbent core, that, when coupled with strategic alignment of certain components and specifically-located folding lines, will create an article with improved convex or outward curvature of the chassis upon unfolding which provides increased spatial separation of the topsheet or body side liner of the article from the genital area of the wearer. In addition, due to the manipulation of the specific location of such elements in the article, gender specific product designs can be created which are specifically tailored to more appropriately deal with the differences in location of the male and female genitalia.

Apparatus (1) and method for producing absorbent structures with absorbent layers with channel(s) without absorbent material, using a first moving endless surface (20) with specific raised strip(s) (25) and a second moving endless surface (30) with specific mating strip(s) (31).

Absorbent article

The present invention addresses the problem of providing an absorbent article that has an improved ability to transfer menstrual blood from a liquid-permeable layer to an absorbent body and can reduce the amount of the menstrual blood remaining in the liquid-permeable layer. To solve this problem, provided is a sanitary napkin provided with a top sheet, a back sheet and an absorbent body that is interposed between the top sheet and the back sheet, wherein convex portions formed in an excretion orifice contact region of the top sheet are coated with a blood lubricity-imparting agent that has a kinetic viscosity of 0.01-80 mm.sup.2/s at 40° C., a water retention rate of 0.01-4.0 mass % and a weight-average molecular weight of less than 1,000.

METHOD FOR MANUFACTURING UNDERPANTS-TYPE WEARABLE ARTICLE
20220265484 · 2022-08-25 ·

A method for manufacturing an underpants-type wearable article where a joining defect of an elastic stretchable member can be easily checked. The method includes: a rubber-thread-sandwiching-step; a continuous-body-forming-step of forming continuous bodies of front and backside waist members; a side-fusing-step of joining both side portions of the front and back members to each other by side fusing using a pair of side fusing portions; a rubber-thread-cutting-step of cutting the rubber threads of the respective continuous bodies of the front and back members at a protruding portion of a boundary region which becomes a boundary of individual wearable article; a joining-state-inspection-step of inspecting a joining state of the rubber threads to a pair of nonwoven fabric; and a continuous-body-cutting-step of obtaining individual wearable articles by cutting the respective continuous bodies of the front and back member at the protruding portion of the boundary region.

Methods and Apparatuses for Making Leg Cuffs for Absorbent Articles
20170266054 · 2017-09-21 ·

The present disclosure relates to methods and apparatuses for assembling absorbent articles that include leg cuff gasketing assemblies. As discussed in more detail below, each leg gasketing assembly may be formed from elastic laminates having stretched elastic strands intermittently bonded thereto. As such, the elastic laminate includes bonded regions and non-bonded regions intermittently spaced along the machine direction. The elastic strands are then intermittently deactivated by severing the strands in the non-bonded regions of the continuous elastic laminate to form continuous lengths of leg gasketing assemblies having elastic regions and deactivated regions. The continuous lengths of leg gasketing assemblies may then bonded to a continuous topsheet substrate. In some embodiments, the elastic laminate may be combined with the topsheet substrate before severing the strands in the non-bonded regions.
