Zusammenfassung:An apparatus and method for manufacturing an elastic composite structure for an absorbent sanitary product includes at least one structure that guides web layers in a machine direction, an elastic thread combiner that combines a plurality of elastic threads to form a combined elastic thread assembly, and a bonding unit. The bonding unit bonds the web layers together via a bond pattern that includes bond lines that each have at least one pair of adjacent bonds, which anchor the combined elastic thread assembly within a passage defined by a pair of adjacent bonds in each of the plurality of bond lines. The passage is narrower than the combined elastic thread assembly in a non-tensioned state and wider than one of the plurality of elastic threads in a non-tensioned state.
