Seal arrangement for retaining a liquid level above a strip passing through a chamber

A seal arrangement for retaining liquid in a chamber at a level above some of the sides of the chamber includes two pairs of rollers. The rollers of each pair contact one another at a height above the low sides of the chamber. The rollers in each pair are arranged at different levels so that the rol...

Zusammenfassung:	A seal arrangement for retaining liquid in a chamber at a level above some of the sides of the chamber includes two pairs of rollers. The rollers of each pair contact one another at a height above the low sides of the chamber. The rollers in each pair are arranged at different levels so that the rollers contact one another at a point higher than the height of the low sides of the chamber. Flexible seal members extend from the bottom of the chamber to a point above the center of each of the bottom rollers. Pressure of liquid in the chamber biases the flexible seal members against the rollers to prevent liquid from leaking along the bottom of the rollers. Restrictions in the outlets of the chamber establish the liquid level at a height which is above the contact point of the pairs of rollers so that both sides of a strip of material passing between the pairs of rollers are washed with the liquid.
