A method is provided for making an elastic composite for incorporation into a disposable absorbent garment. An elastic element applicator is provided that is configured to move a section of a continuous strand of elastic element generally about a plane. A first web of material is conveyed in a first web moving direction such that the first web intersects the plane. Then, the applicator is operated to move the elastic element about the plane, thereby applying the section of elastic element onto the first web along a direction generally transverse to the web moving direction and such that the first web draws the continuous elastic strand from the elastic element applicator as the first web is conveyed away from the plane. The elastic element applicator may be in the form of a spin cylinder or bracket that is operated to spin the elastic element about the moving first web, thereby applying the elastic element on the first web.
