Abstract (en)
[origin: EP0920917A2] The pneumatic adjusting unit has a frame (1-3) containing two spring plates (4,5). The spring plates are secured to the frame (3) at one end and to a setting bolt (8) with a sliding movement at the other end. A compressed air cushion (7) is between the spring plates, linked to a compressed air supply. A spring (10) acts against a lateral deflection by the spring plates. The setting bolt (8) passes through a mounting (9), with a spring (10) at the end away from the spring plates to push the setting bolt (8) outwards. A low friction film is between the compressed air cushion (7) and the spring plates. A monitor registers the path movement of the setting bolt (8), and a monitor registers the deflection movements of the spring plates (4,5) at right angles to the setting direction. An Independent claim is included for a web coating device with a doctor blade as the dosing unit for the web coating, with a support bar under its point with a pneumatic setting unit. Or the setting unit is at the lower lip of a slit jet coating applicator.
