A powder application apparatus contains sheet materials 8, 9, which are delivered from a sheet supply station 7 and are fed to the sheet receiving station 2 and controlled by means of elements 3-6, so that sheet material defines both the floor and the side walls of a spray chamber. The sheet material can be replaced when it is dirty by conveying a new length from the supply station 7 to the receiving station 2, thereby making it possible to clean the spray chamber by simple means and virtually automatically, so that the minimum possible down-time for the unit is achieved. <IMAGE>
