Abstract
A fluidizing and suction withdrawal unit (14) which can be lowered into a container (20) holding a powder (22), in order to fluidize the powder and withdraw the fluidized powder (92) by suction. The fluidizing and suction withdrawal unit (14) is provided with a level sensor (88) which generates a signal, in contingence on the immersion depth (80, 82) to which the fluidizing and suction withdrawal unit (14) is immersed in a powder layer (92) fluidized by it. This assures a consistent feed capacity which also in the case of direct connection of a spray device (76) results in the coating of articles at good coating qualities.
