Controlled deflection roll

Abstract

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.
