Methods and systems for forming a layer from a fluid mixture on a web are provided. The system includes a fluid delivery apparatus for delivering the fluid mixture onto the web. The fluid delivery apparatus includes a cascade device and a chemical dispenser device. The system also includes a fluid stirring apparatus comprising at least one fan positioned over the web and configured to generate a flow pattern that stirs the fluid mixture on the web while the layer is being formed, without the at least one fan contacting the fluid mixture. The system further includes a fluid removal apparatus having a rinsing device and a suction device. The rinsing device is configured to dispense a rinsing fluid onto the web. The suction device is configured to remove by suction the rinsing fluid and a remaining portion of the fluid mixture remaining on the web after formation of the layer.

The invention relates to equipment for changing a blade, which blade is intended to be placed in a blade holder (10) and which is preferably arranged as a flexible band (16). The equipment includes reels (14, 15) for keeping the band (16) reeled and transfer devices (18) for moving the band (16) in the blade holder (10) between the reels (14, 15). In addition, the equipment includes guide devices (17) for guiding the band (16) from a reel (14, 15) to the blade holder (10) and vice versa. The guide devices (17) are also arranged to turn the band (16) longitudinally to be essentially parallel to the blade holder (10). The closest guide member (20) of the guide members (20, 20') belonging to the guide devices (17) is rotated to a position that essentially corresponds to the position of the blade holder (10) turned to the blade-changing position. The invention also relates to a method for changing the blade.

Die Rakelhalterung für ein Rakelband 3 weist eine ohne mehrere Führungselemente 7, 7' auf, wobei diese Führungselemente z.B. Teil einer Kette 6 sind, die in einer Führungsbahn 2 mit einem Trum geführt ist. Dabei greifen die Führungselemente mit einem Greifende 7' in jeweils einer Aussparung des Rakelbandes 3 ein, wobei die Aussparungen in einer Perforationsreihe parallel zu einer Längskante des Rakelbandes angeordnet sind. Das Rakelband ist dabei blattfederartig ausgebildet.

The invention concerns an equipment for replacing a doctor blade, a doctor blade, and a method in the use of band-like doctor blade. The equipment for replacing a doctor blade comprises a doctor blade (11) placed in a reel, which doctor blade can be fed into the blade holder (14) for the doctor blade. The blade holder (14) for the doctor blade (11) comprises locking devices in its connection for locking the doctor blade (11) in the blade holder. The equipment comprises a doctor blade (11) which comprises notches (18a1, 18a2...) at the edge, the doctor blade being fed over a length equal to the distance (E1) between the notches at the edge, while the notches (18a1, 18a2) at the edge are placed, during operation of the doctor blade (11), at both ends of the blade holder (14) and permit bending of the band-like doctor blade (11) in the way of a normal blade in an operating situation.
