Abstract

Arrangement for supply treatment substance, like size or a coating mixture in an application chamber in an application arrangement used in the treatment of paper or cardboard so that the agent intended for feed is uniformly distributed over the entire width of the chamber and the pressure in the application chamber can be kept uniform. The application chamber 10 is formed by the area delimited by the body 2 of the application arrangement, a retention device 6, a scraper device 5, a moving surface 1 and end seals 9. The coating is fed to application chamber 10 from a main pipe 3, which essentially extends over the entire width of the application chamber 10, via nozzles 8 attached to the main pipe 3, which has a channel to guide the agent intended for application from the main pipe 3 to the application chamber 10. A collision lip 12 is formed in the nozzles 8 in front of the channel 13, which discharges into the application chamber 10 to change the direction of the coating jets coming from the channel 10 and to influence the flow properties. <IMAGE>
