Elastic entrapment with waist cap bonding

A method of forming an elastic composite structure comprising:

• providing a first web layer comprising a first portion, a second portion, and a third portion;
• threading a plurality of elastic threads adjacently to the second and third portions of the first web layer;
• folding the first portion of the first web layer over the second portion of the first web layer;
• upon folding the first portion of the first web layer over the second portion of the first web layer, providing a second web layer over the folded first portion of the first web layer, the second portion of the first web layer, and the third portion of the first web layer;
• simultaneously bonding the folded first portion of the first web to the second portion of the first web layer, the folded first portion of the first web to a first portion of the second web layer, and the third portion of the first web to a second portion of the second web layer;
• wherein a first portion of the plurality of elastic threads is trapped between the first and second portions of the first web layer absent adhesive, and wherein the folded first portion of the first web layer is bonded to the second portion of the first web layer around each of the first portion of the plurality of elastic threads;
• wherein a second portion of the plurality of elastic threads is trapped between the third portion of the first web layer and the second portion of the second web layer absent adhesive;
• and
• wherein the first portion of the second web layer is bonded to folded first portion of the first web.
