Abstract
In an apparatus for treating plate-shaped articles in a liquid medium including a bath containing the liquid medium with gap-like inlet and outlet openings arranged beneath the liquid level and a conveying device for conveying the plate-shaped articles along a substantially flat path of conveyance through the inlet and outlet openings and through the liquid medium in the bath, in order to reduce the loss of liquid from the bath, it is proposed that the inlet and outlet openings comprise sealing elements which are movable from a closed to an open position as the plate-shaped articles pass through them and which are furthermore of such design that the gap created by the sealing elements in their open position is substantially adaptable in height and width to the cross-section of the articles passing through it.
