An industrial facility includes: a metal strip in motion; and/or at least one work cylinder; a contactless wiping system of a cooling liquid and/or lubricant jet or stream driven by a surface of the metal strip in motion or the work cylinder, the wiping system including a separating cleat with integrated supply of cooling liquid ending with a nozzle bar to be placed along a width of the metal strip or the cylinder and separated, during use, by a determined interval with respect to the metal strip or the work cylinder, the nozzle bar being oriented so as to supply a jet in a for of a liquid curtain oriented along a direction that is substantially opposite a scrolling direction of the strip or a rotation direction of the cylinder; and a liquid recovery trough, oriented such that during use, liquid sprayed by the nozzles deflects the jet.

Provided herein are systems and methods for containing a viscous material, such as a coolant, on a roll and/or a roll processed engineering material (e.g., a metal strip). In particular, a viscous material containment system can include a movable seal and a gas delivery device. A method for cooling a roll can include applying a viscous material, such as a coolant, to the roll and containing the viscous material on the roll using the viscous material containment system. In some cases, the viscous material containment system can be used to facilitate removal of the viscous material from the roll and/or the roll processed engineering material.
