<p>The invention concerns a threshold construction for a tilting weir where the lower edge of the weirgate (1) is connected with the threshold beam (21) via a rolling seal (11). This rolling seal (11) permits free movement of the weirgate (1). The construction of the support plate (13) makes it possible to influence the operation of the weirgate (1) by altering the profile of the lower edge (9) of the weirgate (1) and the profile of the support plate (13).</p> |
