    Abstract: An electrostatic fluidized bed coating method, apparatus and system utilize a vortex effect within the particle cloud to produce coatings of exceptional uniformity upon a workpiece. The vortex effect produces a secondary particle cloud (102) and a secondary electrostatic field, which contribute to the uniformity of the deposit, and the amount of metal structure included in the unit may be minimized, also to enhance uniformity. Operation can be carried out at voltages that are significantly reduced from those required for similar systems known in the art.

    Abstract: The electrostatic fluidized bed coating apparatus and system employ a vertically extending gaseous vortex of charged particles. Effects of variations in particle distribution, size, and electrostatic charge strength are minimized by the vertical orientation, enabling the production of coatings of exceptional uniformity. The apparatus is especially suited for construction to simultaneously coat a number of strands of wire or the like.

    Abstract: A fiber bundle (B) workpiece is coated with a particulate material during passage about a plurality of pulleys (54, 56) arranged to establish a serpentine travel path portion through a coating zone (10). The pulleys have arcuate grooves (58) extending thereabout, which cause the fiber bundle to twist axially, and the fibers of the bundle move with respect to one another as the fiber bundle moves along the serpentine path. These two actions increase coating efficiency and the penetration of particulate material into the fiber bundle. The travel path portion will preferably lie in horizontal plane, and the coating means will normally constitute an electrostatic fluidized bed of particulate material. After exiting the coating zone, the fiber bundle may pass through an oven (12) to partially melt the particulate material, and thereby cause the particles to adhesively attach to the fiber bundle. The fiber bundle, with particulate material attached thereto, may thereafter be collected and stored on a spool (32) as an intermediate product for use in subsequent composite article manufacturing processes.

    Abstract translation: 纤维束（B）工件在通过多个带轮（54,56）的通路期间涂覆有颗粒材料，所述多个带轮布置成通过涂覆区域（10）建立蛇形行进路径部分。 滑轮具有在其周围延伸的弓形凹槽（58），这导致纤维束轴向扭转，并且当纤维束沿着蛇形路径移动时，束的纤维相对于彼此移动。 这两个动作增加了涂层效率和颗粒材料渗透到纤维束中。 行进路径部分优选地位于水平面中，并且涂覆装置通常构成颗粒材料的静电流化床。 在离开涂层区域之后，纤维束可以通过烘箱（12）以部分地熔化颗粒材料，从而使颗粒粘附到纤维束上。 随后将附着有颗粒材料的纤维束收集并存储在作为后续复合制品制造工艺的中间产品的卷轴（32）上。
