Abstract
The invention relates to a method and a device for stabilizing high speed running along a longitudinal direction, of a band () applied on a rotary surface () and along which a portion of the surrounding air forms a boundary layer () trapped with the band (). According to the invention, a deflecting member () is placed in the dihedron (G) between the band () and the rotary surface (). Said deflecting member () has a face () directed toward the band which is tilted with respect thereto and is fitted with at least one orifice () emerging into an inner space () provided inside said deflecting member () and connected to an outer zone. Thus, said tilted face () forms, with the inner face () of the band (), a convergent (C) wherein the pressure increases with respect to the pressure in the inner space () and the differential pressure determines the exhaust of a certain air flow rate through the orifice () and the separation of the remaining portion of the air mass trapped in the boundary layer ().
