A heated controlled deflection roll equipped with spraying devices arranged in the intermediate space or compartment between the stationary roll support and the roll shell. The spraying devices have walls confronting the inner surface of the roll shell and at which walls there are formed openings which, during operation, form liquid jets. Oil which is infed to the spraying devices can be heated in a collecting container and/or in a tubular conduit. Temperature regulation of the roll shell can also be accomplished by a throughflow or quantitative regulation by means of valves. If there are present a number of temperature zones in the lengthwise direction of the roll shell then different spray devices can be operatively associated with partition walls, from which the liquid is infed to separate collecting containers. From these collecting containers the liquid is again infed, by means of separate pressure lines, to the individual spray devices.

A controlled deflection roll comprising: a stationary roll support; a roll shell rotatable about said stationary roll support; means for rotatably mounting said roll shell for rotation about said stationary roll support; said stationary roll support and said rotatable roll shell coacting with one another so as to form therebetween an intermediate compartment; at least one spray device arranged at the stationary roll support for spraying an inner surface of the roll shell with jets of a heat carrier-liquid at a regulated temperature; said spray device being provided with openings distributed in accordance with a substantially uniform pattern; said openings serving for forming compact liquid jets extending at least in part in parallelism to one another and directed towards the inner surface of the roll shell; and said liquid jets deviating with respect to a normal taken at the inner surface of the roll shell by at most through an angle of 30°.
