Abstract
A device for distributing pulverulent solids in suspension in a gas, for the purpose of depositing a coating, notably by pyrolysis, on a moving substrate (1), includes a distribution nozzle (24), the walls of which define a cavity (11) which terminates in a longitudinal distribution slit (13) and a principal powder feed duct (6) equipped with a distribution portion (7). A plurality of secondary powder feed ducts (8), connected to this principal duct by the distribution portion, enables the cavity (11) of the nozzle (24) to be supplied with powder over its entire length. At least a portion of the secondary ducts (8) is equipped with at least one pneumatic device adapted for modulating the flow rate of the powder-gas suspension which each of the secondary ducts concerned is intended for carrying.
