Abstract (en)
[origin: EP1118708A2] The applicator (10a) for coating the surface of a moving fiber web with a liquid or paste coating medium (28) has a distribution channel (26a) and the flow openings (34) into the equalizing channel (32a) are at the function unit (12a), which is in a swing mounting at or anchored to the carrier structure (14). The distribution channel (26a) has a longitudinal and pref. rectangular cross section. A run-off gutter (56) is under the function unit (12a). A swing drive, with a motor-driven spindle lift, swings the function unit (12a) in relation to the carrier structure (14), and at least one limit stop restricts the swing movement. A further function unit (18a) is mounted to the carrier structure (14) or a fitting (20) at it, as a doctor (42a) to give a dosing and/or equalizing action on the applied coating layer (54) of the coating medium (28) on the web surface (U). The doctor unit (18a), function unit (12a) and the applicator chamber (44a) together form a short dwell time applicator (SDTA). Or the function units (12a,18a) together with an applicator jet form a free stream jet applicator. The function unit (12a) is exchangeable with one cover which forms the limit wall section (31) to define the equalizing chamber (32a), fitted to the carrier structure (14). The replacement function unit has a number of separate applicator jets from the distribution channel, across (Q) the web width, to deliver the coating medium (28) to the running web surface (U). The same structure can be used for an indirect coating action on the web surface (U).
