The invention concerns a coating device with a doctor element for smoothing and dosing the coating mixture and with a chamber for receiving fresh coating mixture, said chamber extending along a support beam of the coating device and having in both cases a length which essentially equals the length of the doctor element, with a feed channel of same length provided which feeds the coating mixture to an applicator space located at the web or at a backing roll (C) serving to carry such web. Within the channel there are provided a spoiler bar aligned parallel to the longitudinal direction of the doctor element, or a row of butting spoiler bars with ribs and slots alternating in the direction of this longitudinal extension, or with projections which in or bar with a continuous row of holes, the spoiler bars or projections reducing the channel cross section before or after the bar or projections by at least 30% of the channel cross section. |
