A non-contact web guide includes a wall having a curved exterior surface and a hollow interior containing a pressurized liquid. A first row of liquid ejection holes is provided in proximity to the web guide entry position having axes that are inclined toward a downstream direction, and a second row of liquid ejection holes is provided in proximity to the web guide exit position having axes that are inclined toward an upstream direction. An intermediate array of liquid ejection holes is optionally provided. The pressurized liquid flows through the liquid ejection holes to force the web of media away from the bearing surface of the web guide. This configuration of liquid ejection holes provides the advantage that stable web guidance is achieved at low liquid flow rates.

A device for metal coating of fibers, for example ceramic fibers, by a liquid process, the device including a crucible containing a liquid metal bath through which a fiber is drawn to be coated with the metal, and a cooling system positioned downstream from the metal bath to solidify the metal sheath created around the fiber by capillarity. The cooling system includes at least one nozzle for ejecting a compressed gas towards the coated fiber, and the system is sized such as to solidify the metal on the periphery of the coated fiber over a length of no more than 200 mm.

In the flux applying device, a control portion controls conveying rollers or the like so that thickness of flux applied to solder is controlled. The winding roller rotates so that the solder is conveyed at the conveying speed. The drawing-out roller applies any load (back tension) to the solder backward along the conveying direction of the solder when drawing out the solder. The solder is conveyed at the predetermined speed and dipped into the flux tank containing flux. The solder is pulled up from the flux tank at the conveying speed vertically. By pulling up the solder from the flux tank at the constant conveying speed vertically, the interfacial tension acts on the solder 9a and the flux, so that the flux having a uniform thickness according to the conveying speed remains on the surface and back surface of the solder.
