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.

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).

METHOD FOR SEPARATING PORTIONS FROM A WEB AND RECOMBINING THESE ONTO THE WEB MACHINE-DIRECTIONALLY OFFSET
20170239100 · 2017-08-24 · ·

The present invention is an equipment and a method for handling web materials, in particular for recombining portions as are cut out from an essentially continuous web material machine-directionally offset with this web.

Absorbent article process and apparatus for intermittently deactivating elastics in elastic laminates

The present disclosure relates to methods and apparatuses for assembling absorbent articles, and more particularly, methods and apparatuses for severing elastic in an advancing elastic laminate. A continuous elastic laminate may be formed by bonding elastic strands between a first continuous substrate layer and a second continuous substrate layer. As discussed in more detail below, the continuous elastic laminate may advance through a cutting apparatus that intermittently deactivates or severs the elastic strands of the elastic laminate along the machine direction.

METHOD FOR MAKING ABSORBENT SANITARY ARTICLES
20170224541 · 2017-08-10 ·

A method for making absorbent sanitary articles including the steps of preparing at least a first continuous web and a second continuous web of material, the first having two longitudinal edges parallel to each other, cutting the first web in such a way as to divide it into a plurality of portions positioned one after the other, rotation and/or translation of at least part of the portions so as to associate them in pairs to define a plurality of pairs of portions and connecting the portions to the second web. The cutting step is performed in such a way as to form, on the first web, an alternating succession of first, second, third and fourth portions, having respective orientations different from each other and each equipped with a first and a second side parallel with each other, defining part of the longitudinal edges of the first web.

Feminine hygiene article with improved wings

Feminine hygiene articles are disclosed herein. The feminine hygiene articles described herein can provide easily discernable placement and orientation guides which reduce the likelihood of misapplication by the user, facilitated attachment guides which can reduce the likelihood of misapplication of the feminine pad and can also reduce the likelihood of improper attachment of the feminine pad to a panty. The feminine hygiene articles disclosed include wings which can provide cues on proper attachment of the article to the panty, and wing adhesive distributed in a way which can provide sustained coverage of the feminine hygiene article to the panty which reduces the likelihood that the pad will become detached during use.

Method and Apparatus for Manufacturing an Absorbent Article Including an Ultra Short Pulse Laser Source
20170266056 · 2017-09-21 ·

The present disclosure relates to methods and apparatuses for assembling absorbent articles, and more particularly, methods and apparatuses for imparting a cut line into one or more layers of an advancing substrate. The advancing substrate may be a belt assembly including an outer layer, an inner layer, and one or more elastic strands disposed between the outer layer and the inner layer. The belt assembly may be rotated on a process member about a longitudinal axis of rotation. The process member may advance the belt assembly to one or more ultra short pulse laser sources. The ultra short pulse laser source imparts a cut line into the belt assembly. A trim removal member may be used to separate the cut line forming a trim portion and a cut edge or separation edge.

METHODS AND APPARATUSES FOR SEPARATING AND POSITIONING DISCRETE ARTICLES
20170266055 · 2017-09-21 ·

Methods of separating and positioning discrete articles formed from a continuous length of articles are provided. The methods may comprise the steps of receiving a first portion of the continuous length on a first head in a receiving position of an orbit about a first rotational axis and receiving a second portion of the continuous length on a second head in the receiving position of the orbit about the first rotational axis. The methods may comprise providing a laser system configured to produce and direct a laser beam, and ablating a portion of the continuous length of articles intermediate the first head and the second head with the laser beam to separate the first portion of the continuous length of articles from the second portion of the continuous length of articles, thereby forming a discrete article on the first head.
