An apparatus are disclosed for coating an article of manufacture to be varnished by coating it with a powdered resin and then heat-cured. A localized powder-cloud is formed internally of a tunnel, the tunnel overlying a tub in which the powdered resin is contained. Means are provided for forming a fluidized bed with the powder particles and means are also provided to provide a temporary adhesion of the powder to the articles (e.g. a glue or a system of electrostatic charges) prior to the final anchoring obtained by curing.
