Abstract: The invention concerns a machine for simultaneously coating the inner surface of several hollow bodies (1). In order to increase the performance of said machine, the hollow body bearing plate (2) has fixing points (22) disposed next to one another in the form of a matrix and the tube support plate (3) has vertically disposed gas feed tubes corresponding with said fixing points (22). A dividing wall (15) that is also vertically disposed and having correspondingly matching holes placed next to one another in the form of a matrix with a quartz window is fixed on the frame (16) of the machine. The bearing (2) and support plates (3) are provided with a drive mechanism (23) for horizontal movement into the machine and for loading and unloading said machine. The dividing wall (15), the hollow body bearing plate (2), the tube support plate (3) and the functional accessories (10, 11, 23-25) thereof form a first module.
