Disposable absorbent pants with advantageous stretch and manufacturability features, and methods for manufacturing the same

A method for manufacturing a disposable absorbent pant, comprising the steps of:

• conveying first and second nonwoven webs along a machine direction;
• sandwiching an elastomeric web between first and second nonwoven webs to form an elasticized multilayer web;
• applying a plurality of pre-strained leg elastic members along a leg elastic path comprising curvilinear portions, onto the elasticized multilayer web;
• applying a plurality of prestrained waist elastic members along a waist elastic path generally extending along the machine direction;
• conveying and laminating a third nonwoven web to the elasticized multilayer web such that the pre-strained leg elastic members are sandwiched between the elasticized multilayer web and the third nonwoven web;
• sandwiching the waist elastic members between a folded over portion of the elasticized multilayer web;
• severing at least one leg elastic member at repeated intervals;
• affixing central chassis structures to overlap the elasticized multilayer web;
• and
• cutting the elasticized multilayer web along separation lines disposed between the affixed central chassis structures, and thereby severing away separate pant structures.

• severing the elasticized multilayer web into front section that is discrete from a back section;
• conveying and laminating a third nonwoven web to front and back sections, indirectly connecting the front and back sections together, such that the pre-strained leg elastic members are sandwiched between the elasticized multilayer web and the third nonwoven web;
• affixing central chassis structures to overlap at least a portion of the front section, the back section, and the third nonwoven web;
• directly joining the front and rear sections;
• and
• cutting the elasticized multilayer web along separation lines disposed between the affixed central chassis structures, and thereby severing away separate pant structures.

A method for manufacturing a disposable absorbent pant, comprising the steps of:

• sandwiching an elastomeric web to form an elasticized multilayer web, wherein the elasticized multilayer web comprises first and second nonwovens;
• applying a plurality of pre-strained leg elastic members along a leg elastic path comprising curvilinear portions, onto the elasticized multilayer web;
• conveying and laminating a third nonwoven web to the elasticized multilayer web such that the pre-strained leg elastic members are sandwiched between the elasticized multilayer web and the third nonwoven web;
• applying pre-strained waist elastic members onto the elasticized multilayer web at each of the front and rear sections, as the elasticized multilayer web is conveyed along the machine direction;
• severing at least one leg elastic member at repeated intervals;
• affixing central chassis structures to overlap at least portions of each of the elasticized multilayer web and the third nonwoven web;
• directly joining the front and rear sections;
• wherein first and second cutting paths include curvilinear cutting path portions defining leg opening cutouts;
• cutting the elasticized multilayer web along separation lines disposed between the affixed central chassis structures, and thereby severing away separate pant structures;
• wherein an end edge of the third nonwoven web is not coterminous with an end edge the first or second nonwoven webs;
• and
• wherein the elastomeric web is a film, and wherein the pre-strained leg elastic members are strands, and wherein the pre-strained waist elastic members are strands.
