摘要：
An apparatus and method for manufacturing an elastic composite structure foranabsorbent sanitary product includes at least one structure that guides weblayers in amachine direction, an elastic thread combiner that combines a plurality ofelastic threadsto form a combined elastic thread assembly, and a bonding unit. The bondingunitbonds the web layers together via a bond pattern that includes bond lines thateach haveat least one pair of adjacent bonds, which anchor the combined elastic threadassemblywithin a passage defined by a pair of adjacent bonds in each of the pluralityof bondlines. The passage is narrower than the combined elastic thread assembly in anon-tensionedstate and wider than one of the plurality of elastic threads in a non-tensionedstate.
