Abstract
The invention is directed to a stationary sliding bar for guiding a paper or cardboard web extends across the entire web width B. Viewed in cross section, the sliding bar has a convex, rounded surface. Due to a relatively high speed of travel of the web, an aerodynamic flotation web forms between the sliding bar and the web.
Claims16
In a machine for one of making and off-line coating of a fiber material web, the web traveling through said machine, the improvement comprising:
- a stationary bar for guiding the traveling web, said bar including a convex, rounded surface disposed adjacent to the traveling web, said rounded surface extending substantially across a width of the traveling web;
- a plurality of individually adjustable raising devices distributed across a length of said bar and carrying said bar, wherein said adjustable raising devices are configured to deflect said bar across said length thereof;
- and
- at least one powered web guide roll which carries and drives the traveling web at an operating speed which is sufficient to define an aerodynamic flotation wedge between said rounded surface and the traveling web, said rounded surface and said operating speed coacting to define a means for separating and preventing contact between the traveling web and said bar.
In a machine for one of making and off-line coating of a fiber material web, the fiber material web traveling through said machine, the improvement comprising:
- a stationary bar for guiding the traveling web, said bar including a convex, rounded surface disposed adjacent to the traveling web, said rounded surface extending substantially across a width of the traveling web, said bar being configured to bow substantially parallel to a direction of movement of the traveling web;
- and
- at least one powered web guide roll which carries and drives the traveling web at an operating speed which is sufficient to define an aerodynamic flotation wedge between said rounded surface and the traveling web, said rounded surface and said operating speed coacting to define a means for separating and preventing contact between the traveling web and said bar.
