A method of making elasticized absorbent pants having a waist opening and a pair of leg openings, the method comprising the steps of: continuously applying multiple distributions of elastics on a moving material sheet to form a moving web of an elastic composite, wherein the multiple distributions of elastics include at least a first distribution of elastic and a second distribution of elastic; periodically applying a core section onto the elastics on the moving web; applying a second material sheet onto the moving web to define a web of discrete elastic composite bodies; shaping the elastic composite bodies into absorbent pants with leg openings and waist openings; wherein said continuously applying said multiple distributions of elastics includes varying the lateral position of the distributions of elastics, relative to a machine direction of the moving web, as the distributions of elastics are advanced in the machine direction toward the moving web of the elastic composite, thereby forming a series of curvilinear sections of the first distribution of elastic and curvilinear sections of the second distribution of elastic, wherein the curvilinear sections of the first and second distributions of elastic mutually and periodically converge and diverge, wherein each of the first and the second distributions of elastics include multiple, mutually spaced apart elastic strands; whereby, at locations whereabout said distributions of elastic converge, at least one of the elastic strands of the first distribution of elastics intersects at least one of the elastic strands of the second distribution of elastics and wherein at least one of elastic strands of the first distribution of elastics does not intersect at least one of the elastic strands of the second distribution of elastics, thereby forming alternating regions including a first region and a second region, wherein elastics of the first and second distributions of elastics are spaced apart at a maximum distance in the first region, and wherein, in the second region, elastics of the first distribution of elastics are positioned closer to elastics of the second distribution of elastics than in the first region; and wherein periodically applying the core section onto the moving web comprises placing the core section in locations on the moving web corresponding to the second regions, whereby said elastics traverse continuously from the first region across an adjacent second region, whereabout said core section is placed, to an adjacent first region.
