<p>The invention relates to a method of manufacturing an absorbent article, wherein the speed of a part of a continuously moving web comprising a topsheet, backsheet, core or any combination thereof, is periodically varied, while maintaining a constant speed of the upstream and downstream parts of the web. The method comprises feeding the web past rotating transport rollers which are oscillated parallel to the web in the direction of transport and opposite to the direction of transport. Three web sections are during oscillation of the transport rollers maintained in a mutually parallel relationship. Translation- and rotation balancing means allow the transport rollers to be driven at high speeds and low variations in torque. The strain exerted on the web remains relatively low and is limited to the inertia forces that act on the web. <IMAGE></p> |
