Abstract
A method of immersing a flexible web of material in a fluid, the method comprising delivering the web to the fluid and subsequently withdrawing the web from the fluid, wherein the web passes through the fluid not under tension. Thus, the web is not constrained by any tensioning means to follow a particular path through the fluid. The web may instead by constrained by one or more walls confining the fluid, typically walls of a fluid container. In this case the path taken by the web through the fluid and the speed of delivery to and withdrawal from the fluid. The invention also covers corresponding apparatus.
