Patent number: 6866213Abstract: An apparatus and method is disclosed for winding a web about a central axis and a rotating mandrel to form a roll. A rolled web product with an alternating winding pattern may be manufactured. A feeding mechanism provides a running web to be wound into a roll. A retainer assembly may be configured for holding the web as it is wound upon the rotating mandrel. The retainer assembly may be configured to accommodate oscillating movement of the rotating mandrel between a clockwise and a counterclockwise direction. The web may be placed upon a roll by winding in one direction and then back again in a second direction repeatedly to form a roll. Retaining means, such as paddles, may be actuated from an active position in contact with the web to a resting position removed from the roll. Paddles may serve to hold the web upon the outer surface of the roll at the time in which the rotating mandrel is changing rotational direction.Type: GrantFiled: December 28, 2001Date of Patent: March 15, 2005Assignee: Kimberely-Clark, Worldwide, Inc.Inventors: Andrew M. Lake, Edward G. Wollangk, Gregory J. Rajala, Moshe Saraf, Daniel J. Oshefsky

Publication number: 20040110618Abstract: The invention is directed to method and apparatus for making pads, such as interlabial pads. Fibers made of different materials are blended and formed into a continuous blended-fiber web. The blended-fiber web is fed to a pad-making apparatus. A first cutting apparatus at a first cutting station cuts the blended-fiber web as it is fed through a first cutting nip to form individual bodies in the web arranged in predetermined positions relative to one another. A first rotatable vacuum transfer cylinder conveys the bodies from the first cutting station toward a sealing roll while maintaining the bodies in their predetermined positions relative to one another. The sealing apparatus laminates a cover web with the bodies at a sealing nip to form a sealed laminated web. A second cutting apparatus at a second cutting station cuts the sealed laminated web to form pads. Folding apparatus may be provided for folding each pad along a major axis thereof.Type: ApplicationFiled: September 30, 2003Publication date: June 10, 2004Applicant: Kimberly-Clark Worldwide, Inc.Inventors: Richard W. Kubalek, Edward G. Wollangk, Thomas P. Keenan, Stephen L. Nunn, James J. Hlaban, Daniel J. Heuer, Dale J. Fischer, Michael K. Lewis, Scott D. Dobslaw, Moshe Saraf
