Apparatus for supplying a coherent curtain of cooling liquid comprises a generally rectangular nozzle with an inlet and an outlet, the nozzle being divided into a multiplicity of individual passages extending in the direction between the inlet and the outlet, a header for introducing liquid coolant to the inlet of the nozzle and a slider displaceable beneath the passages to close off those above the slider and a body carried at the inwards end of the slider providing further passages constituting extensions to those above them and the outer ones of the further passages are inclined outwardly to cause the curtain to diverge as it leaves the nozzle.
