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： A method for combining a tensioned garter with a substrate while holding the garter in a predetermined shape. A mandrel has a perimeter of the desired garter shape. An elastic garter is stretched and placed onto the mandrel such that an upper portion of the garter extends above a top surface of the mandrel while a lower portion of the garter clings to a side wall of the mandrel. The upper portion of the garter has sufficient elastic tension to cause it to fold over onto the top surface of the mandrel to form a garter flange. A substrate is then engaged with the garter flange and a sealing means seals the flange to the substrate, using the top surface of the mandrel as an anvil.

摘要： Non-perforated tear lines for removal and evacuation of contents of disposable undergarments such as training pants. Non-perforated tear lines include a series of bond sites which are shaped, sized, spaced and arranged to provide a zone of weakness to permit severance of nonelasticized portions as well as elastic disposed in the waistband, the body of the pant, and the elastic leg bands for complete removal. Bond sites are formed by displacing a portion of material such that a thickened outer edge defines a weakened area of reduced thickness. Thus, elastic in the waistband may be disposed continuously 360 degrees around the wearer's waist, and elastic in the leg bands may be disposed continuously 360 degrees around the wearer's legs. In addition, improved pants having elasticized ear flaps in the body of the pants can be conveniently removed from the wearer. The shape, size, spacing and arrangement of the individual bond sites is determined for each material used in order to permit severance of the particular material while preventing premature removal. Because the tear lines of this invention are capable of separating elastic, location of the tear lines is not limited to side seams, but may be placed on the front of the pants for convenience.
摘要翻译：非穿孔撕裂线，用于去除和排出一次性内衣如训练裤的内容物。非穿孔撕裂线包括一系列结合部位，其形状，尺寸，间隔和布置以提供弱化区域，以允许切断非弹性部分以及设置在腰带，裤体和弹性体中的弹性腿带完全去除。通过使一部分材料移位使得增厚的外边缘限定厚度减小的弱化区域来形成结合部位。因此，腰带中的弹性可以围绕穿着者的腰围连续地设置360度，并且腿带中的弹性可以围绕穿着者的腿连续地设置360度。此外，可以方便地从穿着者身上移除在裤体内具有弹性化耳襟的改进裤。确定每种材料的形状，尺寸，间距和布置，以便允许特定材料的分离，同时防止过早去除。由于本发明的撕裂线能够分离弹性，撕裂线的位置不限于侧缝，而是可以放置在裤子的前面以方便。

摘要： A method of making a flangeless seam for a disposable article including the following steps: A first member of the disposable article is provided. An electromagnetic field responsive member is provided on the first member. The first member is folded about the electromagnetic field responsive member providing opposing first proximal and first distal portions of the first member, the electromagnetic field responsive member being disposed at least partially between the opposing first proximal and first distal portions. A second member of the disposable article is provided in a folded configuration juxtaposed at least a portion of the first member to form a laminate including the first member and the second member. An electromagnetic field is applied across at least a portion of the laminate to heat the electromagnetic field responsive member to a temperature which joins at least a portion of the first member and at least a portion of the second member. The resulting seam can be opened to provide the article with a flangeless seam.

摘要： A method and apparatus for forming a tensioned garter. A garter is any continuous loop of elastic material or a laminate of elastic bands and one or more flexible backing sheets. In one embodiment mandrels having a perimeter of the desired garter shape are mounted to a rotating drum. Tensioned elastic ribbons are progressively clamped, sealed, and cut around the mandrels to form individual tensioned garters which cling to the side walls of the mandrels. Once the garters are formed the mandrels may be rotated on their radial axes for alignment with downstream operations. Sealing through elastic members is avoided by interrupting the bonding of elastic members to an elasticized laminate at locations where ribbons are to be clamped. High compression of elastics where they are not sealed to the laminate causes elastic members to burst and contract. Elastic contraction leaves an area in which ribbons may then be bonded together without sealing through elastic members.
摘要翻译：一种用于形成张紧袜带的方法和装置。袜带是弹性材料的任何连续环或弹性带和一个或多个柔性背衬片的叠层。在一个实施例中，具有期望的连接器形状的周边的心轴被安装到旋转的滚筒。张紧的弹性带逐渐夹紧，密封并围绕心轴切割以形成紧贴心轴的侧壁的单独的张紧的衣物。一旦形成齿轮，心轴可以在其径向轴线上旋转以与下游操作对准。通过弹性构件在将被夹紧的位置处中断弹性构件到弹性层压板来避免通过弹性构件的密封。弹性体的高压缩性未被密封到层压板上会使弹性构件爆裂和收缩。弹性收缩留下一个区域，其中可以将带状物粘合在一起而不用弹性构件密封。

摘要： A method and apparatus for forming a tensioned garter and bonding it to a substrate while holding the garter in a predetermined shape. A garter is any continuous loop of elastic material or a laminate of elastic bands and one or more flexible backing sheets. In one embodiment mandrels having a perimeter of the desired garter shape are mounted to a rotating drum. Tensioned elastic ribbons are progressively wrapped, sealed, and cut around the mandrels to form individual tensioned garters which cling to the side walls of the mandrels. In another embodiment each mandrel has a top surface. The upper portion of a garter has sufficient elastic tension to cause it to fold over the mandrel top surface to form a garter flange thereon. A substrate is then engaged with the garter flange and an external sealing means seals the flange to the substrate, using the mandrel top surface as an anvil. In still another embodiment the mandrel top surface has a raised outer rim. An ultrasonic horn seals a garter flange to a substrate where they are supported by the mandrel rim. The mandrel rim is shaped to provide a continuous seal which is weakened at its inner edge. When the weakened edge is broken, substrate and garter materials inside the seal edge are removed, thereby forming a hole around which the remaining portion of the garter may contract. Vacuum is applied from the mandrel top surface to the substrate inside the garter in this embodiment in order to break the seal edge and remove this material as the substrate and garter are stripped off the mandrel.
