AbstractA feed device for paste-like mixtures such as paper pulp is designed to form a flat film of paste through at least one nozzle at the outlet from a distribution chamber. Paste-like mixture feed circuits discharge into the distribution chamber and each circuit comprises a liquid feed channel and a concentrated paste feed channel each incorporating a flowrate adjuster valve and connected downstream of the valves by a mixer. The mixer comprises an outlet connected to an inlet of the distribution chamber. The distribution chamber comprises ejection channels delimited by longitudinal partitions. Each circuit is in corresponding relationship with one ejection channel.
