Exemplary illustrations of a bell cup for a rotary atomizer and method of using the same are disclosed. The exemplary illustrations are generally directed to the control of the rotating bell plate of a rotary atomizer used for the serial coating of work pieces. An air flow component may be created by the structural design of the bell plate and/or of an element of the rotary atomizer and by the rotation of the bell plate. The air flow component may correspond to the bell plate design, and the element may be adjacent to the bell plate and stationary relative to same. The air flow component may be measured and compared to a predefined reference value.

Rotary atomizer and method for the control of the spraying body of said rotary atomizer

A deflecting air ring includes a plurality of deflecting air nozzles for discharging a deflecting air jet onto a spray jet of a vaporizer in order to shape the spray jet. The deflecting air nozzles are configured such that the deflecting air jet is substantially laminar within a first region, while the deflecting air nozzles also generate turbulence in a second region situated downstream of the first region of the deflecting air jet.

Deflecting air ring and corresponding coating process

A deflecting air ring is disclosed having a plurality of deflecting air nozzles for discharging a deflecting air jet onto a spray jet of a vaporizer in order to shape the spray jet. The deflecting air nozzles are configured such that the deflecting air jet is substantially laminar within a close region, while the deflecting air nozzles also generate turbulence in a remote region situated downstream of the close region of the deflecting air jet.

The invention relates to an application element () for a rotary sprayer, in particular in the form of a bell-shaped plate or a rotary disc, with an overflow surface () which, during the coating operation, rotates together with the application element () and is overflowed by a coating agent to be applied, and with a surface layer which is located on the overflow surface () and on which a thin coating agent film forms with a certain film thickness during operation, wherein boundary surface friction acts between the coating agent film and the surface layer. It is proposed that the surface layer reduces the boundary surface friction between the coating agent film and the overflow surface (). Furthermore, the invention comprises an associated operating method.
