Definitions
- the invention relates to a device for contactless deflection of a moving web, in particular a paper or cardboard web, by means of a Air cushion according to the preamble of claim 1.
- the invention has for its object a generic deflection device to improve so that the web runs in a stable path without fluttering onto the web Leading surface runs up and leaves this again.
- a cover plate projects into the wedge-shaped space between the Web and the housing on the inlet and / or the outlet side. This leads to a Stabilization of the air flow and thus prevents the web from fluttering.
- the deflection device contains an essentially closed housing 1 in the form of a cylinder segment that extends over the entire width of the to be deflected Paper web 2 extends.
- One of the housing 1 forming, in the longitudinal direction Boundary walls 3 extending over the entire width of the web is designed that its outer wall surface serving as a guide surface corresponds to the desired path runs curved.
- the boundary wall 3 contains Air outlet openings 4 over the entire area as a guide surface for the web 2 serving outer surface are arranged.
- the air outlet openings 4 are either Holes arranged in rows or slots. The rows of holes or slots each extend over the entire width of the web and are in the direction of web travel Spaced from each other so that air emerging from them is an air cushion forms on which the web 2 floats.
- the housing 1 from a Cover wall 9 completed, which is also over the entire width of the web extends.
- the housing 1 is supported by a side plate 10 on each of the two end faces completed, which is designed to match the cross section of the housing 1. in the Inside the housing 1 is an air duct 11 which extends over the web width arranged, which is closed on one side by the side wall 10, on the other side via a corresponding opening in the side wall 10 to a not fan shown is connected.
- the housing is in the working width Area between the air duct 11 and the outer boundary walls 3, 5, 9 divided into individual segments by transverse bulkheads, each of which has an im Cross section changeable air flap in connection with the interior of the air duct 11 stand. It can be the air supply from the air duct 11 to the individual Set segments.
- a cover plate 12, 13 is arranged, which extends from the housing 1 in the direction extends to lane 2.
- Each cover plate 12, 13 extends substantially over the entire web width, i.e. the length of the housing 1, and ends in one Distance between 5 mm and 30 mm from the web 2.
- Each cover plate 12, 13 protrudes so as an obstacle to the flow from the air cushion between the Boundary wall 3 and the web 2 in or against air flowing air in the wedge-shaped space 7, 8 between a longitudinal wall 5, 6 and the web 2. So the flow behavior of the outflowing air to prevent a Track flutter affected.
