A stretch laminate having a first substrate is adhesively attached to an elastic film. The adhesive is applied in a continuous manner to the substrate in a first tack down region which is disposed proximate to an end of the stretch laminate. The adhesive is applied as a plurality of adhesive stripes in an activation region which is interior of the first tack down region. The adhesive stripes have a width and a distance between adjacent adhesive stripes. The ratio of stripe width to distance between the adhesive stripes is in the range of less than about 1 or greater than about 0.33.

Stretch laminates

A method of producing a stretch laminate exhibiting reduced defects from a mechanical activation process can include providing a nipping member. The nipping member can have a first nip region and a non-nip region adjacent to the first nip region. A first substrate and an elastic element are provided to the nipping member. The first substrate and the elastic element are joined in a face to face relationship with adhesive therebetween, thereby creating an intermediate laminate. The intermediate laminate has a first tack down region and an activation region adjacent the first tack down region. A portion of the first tack down region passes through the first nip region, and a portion of the activation region passes through the non-nip region of the nipping member. The activation region of the intermediate laminate is mechanically activated, thereby creating the stretch laminate.

Method of producing a stretch laminate

A method for producing a stretch laminate includes forming an intermediate stretch laminate. Forming the intermediate stretch laminate includes providing a first substrate and attaching an elastic film to a surface of the first substrate via an adhesive. The first substrate and the elastic film are in a face to face orientation. The intermediate stretch laminate has a residual energy of greater than or equal to 50% at a predetermined applied strain. The method of forming the stretch laminate further includes mechanically activating the intermediate stretch laminate at a strain rate of at least 100 s.

A method and an apparatus for pre-fastening disposable absorbent articles having a slot-and-tab fastening system during manufacturing of the pre-fastened disposable articles, such as diapers, pull-on diapers, training pants, adults incontinence pads and the like.

A method for inducing strain on a workpiece includes the step of providing a testing apparatus having a first set of teeth and a second set of teeth. The workpiece is placed adjacent to the first or second set of teeth. The second set of teeth is disposed on a movable carriage which linearly reciprocates thereby allowing the first and the second sets of teeth to engage and disengage each other. A commanded position by time is provided to the carriage while the actual position by time of the carriage is measured. The first set of teeth are in communication with at least one load cell such that when the first set of teeth engage the second set of teeth, the load applied by the carriage is measured. The actual position by time data and the load data are manipulated to produce vast information pertaining to the workpiece.

An improved sanitary napkin is disclosed. The sanitary napkin has a laterally extensible flap which extends outwardly from one of the longitudinal edges of the sanitary napkin or a laterally extensible backsheet. The backsheet or flap may be laterally extended from the neutral, retracted position and will return to the retracted position upon release of the disturbing force. This arrangement provides the advantage that any adhesive strips or patches associated with the flaps or backsheet more easily move with the undergarment of the wearer and are less likely to be stressed or become detached from the undergarment of the wearer due to the forces encountered during typical wearer movements.

A method for making an absorbent article having a transverse partition including the following steps: a) providing a first web of barrier leg cuff material having a generally uniform width in a machine direction; b) providing a second webs of barrier leg cuff material in a machine direction generally parallel to the first web of barrier leg cuff material; c) activating at least a portion of said first webs so as to provide an activated region which is extensible in at least said lateral direction; d) providing a transverse partition having a proximal edge and a distal edge; e) joining at least a portion of the transverse partition adjacent the distal edge to the first webs of barrier leg cuff material adjacent to the activated region of the first web of barrier leg cuff material; f) providing a third web of topsheet material; g) joining at least a portion of each of the first and second webs of leg cuff material to the third web of topsheet material; h) providing a fourth web including an absorbent material disposed on a backsheet material; i) joining the third web of topsheet material to the fourth web to form a diaper web; and j) cutting the diaper web into individual absorbent articles.

A disposable absorbent article, such as a sanitary napkin, is disclosed that has components which may separate in the Z-direction with relation to other components of the article when the absorbent article is worn. The sanitary napkin of the present invention comprises a liquid pervious topsheet, a liquid impervious backsheet, an absorbent core positioned between the topsheet and the backsheet, and a liquid pervious spacing structure for moving the topsheet away from the core. The spacing structure is generally positioned between the topsheet and the core. The spacing structure has a longitudinal centerline, and opposed lateral sides which may move inwardly toward the longitudinal centerline when the spacing is compressed from the sides. This results in at least a portion of the spacing structure moving the topsheet apart from the absorbent core. In an alternative embodiment, the sanitary napkin of the present invention also has an absorbent core which separates from the backsheet of the sanitary napkin.
