    • Apparatus for electrostatic spray coating of plate-like substrates, particularly printed circuit boards, has one or more endless conveyors or one or more conveyors of finite length with one or two pairs of strip-shaped holding elements for the edges of substrates. The holding elements engage a substantial part or the entire edge of the substrate which is transported through one or more spray coating stations. Each holding element is made of or contains an electrically conductive material, and the holding elements are grounded, at least during travel through the coating station or stations. The holding elements can engage the edges of substrates by friction or they are coated with an adhesive so that they adhere to the edges of the substrates.
    • 用于板状基板,特别是印刷电路板的静电喷涂的设备具有一个或多个无端输送机或一个或多个有限长度的输送机,其具有用于基板边缘的一对或两对带状保持元件。 保持元件接合通过一个或多个喷涂站输送的基底的大部分或整个边缘。 每个保持元件由导电材料制成或包含导电材料,并且保持元件至少在行进通过涂布站或站时接地。 保持元件可以通过摩擦接合基板的边缘,或者它们用粘合剂涂覆,使得它们粘附到基板的边缘。
