Abstract
The front, back and bottom walls of the tanks containing the solutions are constructed of rollers which are arranged in abutting rolling contact so as to form a liquid-tight seal with one another. The rollers are constructed of relatively soft rubber such that film can be passed between adjacent rollers in the side walls directly into the solution.
