Abstract: The present disclosure provides for the description of rotary unions. The described rotary unions are provided with a non-rotating union part and a rotating union part affixable to a rotating device. An exemplary rotary union can be positioned relative to a bearing supporting the rotating device and the rotating device or can be incorporated into a bearing supporting the rotating device.

Abstract: Embossed multi-ply fibrous structures and methods for making such embossed multi-ply fibrous structures are provided.

Abstract: A rotary device for high-speed printing or coating of a web substrate is disclosed. The printing system provides a gravure roll rotatable about an axis at a surface velocity, ?, and a fluid channel having a pressure drop throughout the fluid channel due to friction, Pf, disposed therein. The fluid channel is disposed generally parallel to the axis at a distance, Rin, relative to the axis. The fluid channel provides fluid communication of a fluid having a fluid vapor pressure, Pv, and a fluid density, ?, from a first position external to the gravure roll to a web substrate contacting surface of the gravure roll. The web substrate contacting surface is located at a distance, Rout, relative to the axis. Rin is determined from the relationship: R in R out > 1 - 2 ? ( P out - P v + P f ) ? ? ? v 2 where Pout=static pressure of the fluid channel at the web substrate contacting surface.

Abstract: A method for processing a web material having a machine direction and a cross-machine direction coplanar and perpendicular thereto is disclosed herein. The method incorporates the step of first directing a web material proximate to an air foil. Steam is then applied to the web material by the air foil. Finally, the web material is processed by any downstream web material processing operation.
