摘要

A method for producing pant-type articles having a waist-encircling portion and leg-encircling portions. The method includes forming a chassis structure and at least one elastic panel being formed by providing a first web, which is an elastic web including at least one layer of an elastic material. The first web is stretched at least 70% in at least one direction. The stretched first web is bonded while the first web is held in the stretched state to a second web. The second web includes at least one layer of an elastic or non-elastic material, and the bonded first and second webs form an elastic composite web. The elastic composite is relaxed in the at least one direction by at least 4% of the stretched length of the stretched first web. The chassis structure is assembled from chassis components including the stretched and relaxed composite web.
