摘要:
The present disclosure provides methods of manufacturing a body adhering absorbent article oriented in the machine direction wherein the body adhering absorbent articles have reduced or eliminated curl. The articles are manufactured with reduced curl by selectively reducing or eliminating the shell elastic tension in regions where components of the body adhering absorbent article are to be attached to form the composite absorbent article web. In certain aspects the body adhering absorbent articles are manufactured by supplying an elastic web of shell material having a longitudinal and transverse direction, stretching the web of shell material in the longitudinal direction, deadening at least one region of the stretched web of shell material, attaching at least one absorbent article component to at least a portion of the longitudinal deadened zone to form a composite web material, and cutting the composite web material to form a body adhering absorbent article.

A process and apparatus for registering a plurality of discrete components to a continuously moving first layer of material produces a disposable absorbent garment with improved alignment of the components on the first layer of material. The first layer has a plurality of reference marks positioned thereon. Various devices are used to compare distances between the reference marks to distances between corresponding components and synchronize a feed rate of the components to a feed rate of the first layer. After adhering the components to the first layer, the positions of the components relative to the reference marks are once again checked and, if necessary, the setpoint for the feed rate of the components is adjusted.

A process and apparatus for controllably registering two continuously moving layers of material is provided. A continuously moving first layer has a plurality of components, and a continuously moving second layer has a plurality of reference marks representing a respective plurality of components. The process and apparatus control the distance between reference marks of the second layer to a selected distance, and then controllably registers each reference mark of the second layer to a respective component of the continuously moving first layer.
摘要:
The present disclosure provides a method of manufacturing body adhering absorbent articles orientated in the cross-machine direction, body adhering absorbent article having reduced or eliminated curl. The articles are manufactured with reduced curl by selectively reducing or eliminating the shell elastic tension in regions where components of the body adhering absorbent article are to be attached to form the composite absorbent article web. In certain aspects the body adhering absorbent articles are manufactured by supplying an elastic web of shell material having a longitudinal and transverse direction, that is stretchable only in the transverse direction, attaching at least one component to form a composite web material, and cutting the composite web material to form a body adhering absorbent article.
摘要:
A boxer-style pant and a method of making a boxer-style pant having side seams and hanging legs. Expandable material is used to provide a conforming fit and to expedite high-speed manufacture. The pant is made from a web and includes a garment shell having a front region, a back region, and a crotch region positioned between the front and back regions. The side seams connect the front region to the back region. The garment shell may be essentially composed of an expandable material that is selectively expanded in certain areas of the garment, and/or an expandable material may be attached to the garment shell in the crotch region and/or in the back region.

An apparatus and a method are disclosed for manufacturing several distinct disposable absorbent articles on a single machine. The apparatus includes three sections. The first section is capable of forming an absorbent assembly and cutting the absorbent assembly into individual absorbent assemblies. The second section is capable of moving a bodyside liner into alignment with the individual absorbent assemblies and applying an outer cover to the individual absorbent assemblies to form a continuous web having a primary stretch in a cross direction. The second section is further capable of adding at least three components to the web. The third section is capable of severing the continuous web into individual absorbent articles which can then be folded, stacked and packaged.
摘要:
A boxer-style pant and methods of making a boxer-style pant having side seams and hanging legs. At least a portion of each of the hanging legs may be non-planar in an uncontracted state prior to formation of the side seams. The methods each involve providing at least one web. In some methods, a crotch panel is bonded to first and second regions of the web between two leg openings, and a distance between bonded regions of upper and lower edges of the crotch panel, measured parallel to a longitudinal axis of the pant, is shorter along a central region of the crotch panel and longer in distal regions of the crotch panel, such that the bonded region results in a bow-tie-shaped crotch panel. In some methods, a crotch region of the web is folded and stabilized along a longitudinal centerline of the web. In some methods, leg extensions are attached to at least a portion of each of two leg openings. Front and back regions may be joined together to form the side seams. An absorbent structure may be attached to the web.

A pant has a garment shell. The garment shell includes a front region, a back region, a contracted crotch region, side seams connecting the front region to the back region, two leg openings, and hanging legs. At least a portion of each of the front region, the back region, the contracted crotch region and the hanging legs include portions of a single flat web. The hanging legs include no elasticization around a full periphery of the leg openings and are adapted to hang loosely about a wearer's thigh.

A boxer-style pant and a method of making a boxer-style pant having side seams, a contracted crotch region, and hanging legs. A web is provided. The web may be a single pant assembly, or a continuous web of multiple pant assemblies connected to one another. The web may be folded against a support structure. In certain embodiments, a multi-lane production system may be used wherein the web is folded against multiple support structures each parallel to a direction in which the web is conveyed, with each lane or machine direction array of pant assemblies folded against just one support structure. The web is cut to define leg openings, and contracted in selected areas along the web between the leg openings. Front and back regions are then joined together to form the side seams. An absorbent structure may be attached to the web.
