<p>Apparatus is known for controlling the deposition of a liquid onto a moving surface comprising a reservoir having an outlet, and a curved guide member downwardly extending from above and adjacent to the outlet and having an underside onto which a jet of liquid can be discharged from the outlet, the guide member being oriented so as to be capable of causing liquid to flow down the member on its underside so that its direction of flow approaches the direction of travel of a moving surface. This invention is characterized in that two aprons are provided at the lower edge of the reservoir outlet so as to extend beneath the jet being discharged from the outlet, the first of the said aprons extending only part of the distance towards the moving surface and the second of the said aprons extending beneath the said apron so that the free end thereof is substantially in contact with the moving surface, the arrangement being such that the lower edge of the first apron is in engagement with the upper surface of the second apron.</p> |
