Abstract
Apparatus for the surface treatment of strips with liquid, in particular for the pickling of rolled metal strip. The apparatus comprises a pickling vessel (3), through which the strip (10) is advanced, closed by a cover (4). Between the strip (10) and the cover (4) a means is provided which if the strip rises upwards, guides the latter back into the direction of movement. This means can be formed of profiles providing a sawtooth-like configuration. Such profiles may be formed by guide means (11) which are chamfered on the side from which the strip enters.
