摘要： This invention relates to a continuous process for electrostatically coating a substantially axially symmetrical object with pulverized material, characterized by conveying said object by means of a conveyor-type holding device into an electrostatic coating chamber equipped with silent discharge plate electrodes on both sides of the chamber walls: feeding electrically charged pulverized material into said chamber: electrostatically coating said object with said pulverized material by the action of silent discharge from said electrodes: and removing surplus pulverized material from the specific parts of said object by suction.This invention further relates to an apparatus used for continuously electrostatically coating a substantially axially symmetrical object with pulverized synthetic resin, characterized by comprising (i) an electrostatic coating chamber where said pulverized synthetic resin is coated on the surface of said object maintained at a temperature below the melting point of said resin, which object has been conveyed into said chamber by means of a holding device and (ii) a device for removing surplus pulverized resin from the specific parts of said object by suction in order to electrostatically coat the desired part only.
摘要翻译：本发明涉及一种使用粉碎材料静电涂覆基本上轴向对称的物体的连续方法，其特征在于，通过输送机型保持装置将所述物体输送到在所述室的两侧装备有无声放电板电极的静电涂层室将带电荷的粉碎材料供给到所述室中：通过所述电极的静音放电的动作，用所述粉碎材料静电涂覆所述物体;以及通过抽吸从所述物体的特定部分除去多余的粉碎材料。本发明还涉及一种用于用粉碎的合成树脂连续静电涂覆基本轴向对称的物体的装置，其特征在于包括：（i）静电涂覆室，其中所述粉碎的合成树脂被涂覆在所述物体的表面上，保持在低于所述树脂的熔点通过保持装置被输送到所述室中，以及（ii）用于通过抽吸从所述物体的特定部分除去多余的粉碎树脂的装置，以仅静电涂覆所需的部分。
