Disclosed is a powder coating station (1) for electrostatically coating a first and second side of a workpiece (3) that is moved relative to the coating station (1). Said powder coating station (1) comprises at least one first delivery unit (4, 5) for delivering coating particles as well as at least one first electrode array (6, 7, 8, 9) for influencing the coating process of the workpiece (3) by modifying the shape of the line of force in the edge regions of side 3a. A method for coating a first and a second side of the workpiece (3) encompasses the following steps: an arrangement (1) is provided which is composed of at least one delivery unit (4, 5) and at least one electrode array (6, 7, 8, 9) that is associated with the delivery unit (4, 5) and comprises at least one electrode; the workpiece (3) is moved relative to the coating station (1) along a section, past the arrangement (1); coating particles for coating the workpiece (3) are delivered during the relative movement of the workpiece (3); and a positive or negative voltage and/or charge is applied to the electrode array (6, 7, 8, 9) during at least one partial period of the coating process while the delivery unit (4, 5) is poled with another polarity sign than the electrode array (6, 7, 8, 9). |
