A coating of paint on a panel is dried by directing a narrow jet of air from a supply, preferably from an air mover, held at a predetermined distance from the panel towards one edge region of the panel, the jet being substantially narrower, when it reaches the panel edge region, than the length of the panel edge and the jet being inclined to the plane of the panel such that the air from the jet is entrained by the panel in a spreading laminar flow across the panel surface from that edge region to all the other edges thereof. This induces such laminar flow over substantially the whole surface and replaces vapor-laden air closely adjacent the surface with fresh air to accelerate drying. In a painting booth for cars several such air movers use part of the bulk air flow in the booth.
A method of forcing evaporation of a solvent such as water from a coating on a predefined surface of a panel comprising directing a jet of air from an air supply held at a predetermined distance from the panel towards one edge region of the panel, the jet being substantially narrower, when it reaches the panel edge region, than the length of the panel edge and the jet being inclined to the plane of the panel such that the air from the jet is entrained by the panel in a spreading, predominantly laminar flow across the panel surface over that edge region and from that edge region to all the other edges thereof, thereby inducing such laminar flow over substantially the whole surface and replacing vapor-laden air closely adjacent the surface with fresh air to accelerate drying.
A method according to any preceding claim, in which the width of the jet of air in the plane of the panel as it reaches the panel edge portion is between 10% and 20% of the length of the panel edge.
A booth or other enclosure for the painting or re-painting of panelled articles such as motor vehicles, comprising an air inlet and an air outlet for the bulk movement of drying air over a painted article standing in the booth;
