Abstract (en)
[origin: US5005769A] The invention relates to a device for the distribution of pulverulent product on a substrate. The device has two walls delimiting a blade-shaped cavity converging toward substrate, a gas injection chamber closed by a plate, pierced with a multiplicity of jets 12 for injecting a gas under pressure inducing ambient air into the cavity substantially parallel to the wall of the cavity which is adjacent thereto which homogenizes the pulverulent gas product mixture and accelerates it in the direction of the substrate, thus forming a uniform thin layer on a substrate.
