A strip flotation furnace for controlling the temperature of a metal strip has a flotation nozzle bar extending through the furnace transversely to a strip running direction of the strip. The flotation nozzle bar has two opposing first flotation nozzle rows spaced apart by a central region of the flotation nozzle bar. The rows are set up so that corresponding flotation nozzle jets, with a directional component toward the central region, can be generated to provide pressure cushioning for metal strip guiding. A temperature-control nozzle bar extends transversely to and is spaced apart from the flotation nozzle bar along the strip running direction. The temperature-control nozzle bar has two additional opposing temperature-control nozzle rows spaced apart by an additional temperature-control nozzle bar central region. These rows are set up so that corresponding temperature-control nozzle jets, with a directional component opposite to the additional central region, can be generated.

An air nozzle apparatus that includes an air orifice and a nozzle housing, said nozzle housing configured as u-shaped having a first elongated sidewall, a second elongated sidewall, and a third curved sidewall formed continuous with said first elongated sidewall and said second elongated sidewall to form a channel having an open end opposite said third curved sidewall, said air orifice positioned centered in said channel and proximate a base of said third sidewall facing said open end, wherein said first elongated sidewall, said second elongated sidewall, and said third curved sidewall are configured having an arched top surface, and, thus, functions to optimize the Coanda effect to position and convey the paper web through an air threading chute to thread a paper web from the end of the drying step through the dry-end to the paper winding step.

An apparatus for transporting a tail end in a fiber web machine from one structural section to another includes nozzles for guiding the tail end on the guide plate by means of an air flow such that the blown air is brought onto a guide plate shaped into a curve in such a way that the air flow of the blown air guides the tail end onto the curved guide plate by means of a bump functioning as an aerodynamic profile formed in the curved guide plate.

A nozzle (10) for contact-free treatment of a running web, having a main frame (11) forming an outer part of the nozzle, and two side chambers (14, 15) on each of the longitudinal sides of the nozzle (10). The side chambers having openings (17A, 17B, 16A, 16B) for the air to blow toward a fiber web. A U-shaped air channel (20), through which the air is lead to the side chambers (14, 15), located between the side chambers (14, 15), having at least one opening (19, 18) on each side wall for leading the air into the side chambers (14, 15). A U-shaped inner part (13) which is movable by a mechanism (12) comprising a screw (21) and bushings (22) to at least partially open and close the opening (18, 19).

A web transport system for transporting a web of media along a web transport path in an in-track direction, including a liquid application system for applying a liquid to at least one surface of the web of media. An air skive is positioned along the web transport path downstream of the liquid application system, wherein the air skive directs one or more streams of air onto the web of media thereby removing at least some of the liquid that is being carried along with the web of media. A vapor source adds a vapor into the one or more streams of air provided by the air skive before the one or more streams of air are directed onto the web of media.

Systems and methods are disclosed for starting a strip material in a substrate processing machine wherein the machine is not stopped and/or operators do not have to reach into the running machine to start the strip material. Exemplary systems include a strip material guide apparatus including at least one guide arm and at least one gas stream generator configured to direct strip material from the guide arm into a substrate processing machine to join the strip material with one or more running substrates. The gas stream generator is operable to cause a leading end of a strip material dispensed from the guide arm to be conveyed via a gas stream toward the running substrates, such that the leading end of the strip material becomes engaged by the substrate processing machine and the strip material joins with the running substrate.
