Abstract

In the region of the upper edge of the sheet pile (8) and facing the latter, there is provided a plate (2) with a microporous structure. Because of the microporous, air-permeable structure, there is a homogeneous emergence of compressed air over the entire surface of the plate (2), so that no oscillation or fluttering can occur in the sheets (7) against which the air is blown. <IMAGE>
