    Abstract: Method and apparatus for dispensing a web of absorbent material selectively in a dry or wetted condition, including means for holding an indeterminate length of web material and drive rolls defining a nip therebetween through which the web is threaded for dispensing. Guide means provided intermediate the drive rolls and the web supply selectively guides the web over the surface of fluid contained in a reservoir or dips a length of the web beneath the surface of the fluid. Forward rotation of the drive rolls dispenses a length of web. In one embodiment, by reason of means interconnecting the guide and a drive roll, reverse rotation of the drive rolls causes the guide to engage the web and move a length of web into contact with the fluid contained in the reservoir.
