Abstract
The object of the invention is a processing installation, particularly a metal strip pickling installation, comprising a series of vats (2) filled with a pickling liquid (20), each vat (2) being separated from adjacent vats by two bulkheads. The upper portion of these bulkheads has a sill located above the level of the liquid (20) and which supports the strip (1). According to the invention, each sill (22) is fitted with a support part limited by a rounded, upwardly convex, contact face (4) on which a liquid recovery groove is provided. This liquid recovery groove extends along the upper part of the supporting part at right angles to the strip feed direction, and is extended, at at least one of its ends, by a return channel leading to the upstream vat (2a). The bottom (53) of the groove (5) and return channel (6) are downwardly inclined to allow the liquid recovered in the groove (5) to return naturally to the upstream vat (2a).
