A method for manufacturing a disposable absorbent pant, comprising the steps of: advancing a front elasticized multilayer web and a rear elasticized multilayer web along a machine direction, the front elasticized multilayer web and the rear elasticized multilayer web each comprising an elastomeric web sandwiched between a first nonwoven web and a second nonwoven web; providing a plurality of pre-strained leg elastic members along a leg elastic path generally extending along the machine direction but comprising curvilinear portions; connecting the front and rear elasticized multilayer webs together with a third nonwoven web such that the pre-strained leg elastic members are sandwiched between at least one of the front and rear elasticized multilayer webs and the third nonwoven web; cutting the front elasticized multilayer web along a first cutting path and cutting the rear elasticized multilayer web along a second cutting path; affixing central chassis structures to overlap the front and rear elasticized multilayer webs; and cutting the front and rear elasticized multilayer webs 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: advancing a front elasticized multilayer web and a second elasticized multilayer web in a machine direction, each of the front multilayer web and the second multilayer web comprising an elastomeric web sandwiched between a first nonwoven web and a second nonwoven web; providing a plurality of pre-strained leg elastic members along a leg elastic path comprising curvilinear portions; providing a plurality of pre-strained waist elastic members along a waist elastic path; connecting the front and rear multilayer webs together with a third nonwoven web such that the pre-strained leg elastic members are sandwiched between at least one of the front and rear elasticized multilayer webs and the third nonwoven web; sandwiching the waist elastic members between a folded over portion of the front and rear elasticized multilayer webs; cutting at least one leg elastic member at repeated intervals; affixing central chassis structures to overlap the front and rear elasticized multilayer webs; and cutting the front and rear elasticized multilayer webs along separation lines disposed between the affixed central chassis structures, and thereby severing away separate pant structures.
