Patented is a method for manufacturing a disposable absorbent pant, comprising the steps of: conveying a first nonwoven web along a machine direction; as the first nonwoven web is conveyed along the machine direction, applying an opposing pair of pre-strained leg elastic members along leg elastic paths generally extending along the machine direction but comprising curvilinear portions, onto a surface of the first nonwoven web; as the first nonwoven web is conveyed along the machine direction, laminating a second nonwoven web to the first nonwoven web and thereby sandwiching the pre-strained leg elastic members between the first and second nonwoven webs to form a first elasticized multilayer web; as the first elasticized multilayer web is conveyed along the machine direction, cutting the first elasticized multilayer web along two cutting paths, severing each of the leg elastic members at repeated intervals, and removing a middle section of the first elasticized multilayer web between the cutting paths, to leave behind front and rear waist sections of the first elasticized multilayer web; as the front and rear waist sections are conveyed along the machine direction, laminating a third nonwoven web to the front and rear waist sections to form a second elasticized multilayer web; as the second elasticized multilayer web is conveyed along the machine direction, affixing central chassis structures thereto to form a combination web structure; cutting the second elasticized multilayer web along separation lines disposed between the affixed central chassis structures, and thereby severing away separate pant structures.
