Abstract
A continuous web as a component of a disposable wearing article is fed in a machine direction and first continuous elastic members are fed via guide elements adapted to oscillate the elastic members in a cross direction. Each of the guide elements has a first servomotor having a rotary shaft adapted to repeat reversal of its rotational direction, a first arm connected directly with the rotary shaft and extending in a direction crossing the rotary shaft so that the first arm swings around the rotary shaft as the rotary shaft rotates, and a first feed member adapted to direct the first continuous elastic members toward the guide element formed on the first arm.
