Abstract: An electrostatic flocking operation of a workpiece (5) is advantageously performed in a condition in which the moisture content of an adhesive layer formed on a surface of the workpiece (5) is kept at a favorable value by a humidifier (1). The humidifier (1) is provided between an electrostatic flocking chamber and an adhesive applicator which is disposed in the upstream side of the electrostatic flocking chamber. In the humidifier (1), a current of a moisture bearing air (2) is driven upon the adhesive layer of the workpiece (5).

Abstract: In order to obtain an evenly flocked and an evenly coated surface of a strip-like elongated workpiece, any slack of the strip-like elongated workpiece is removed not to affect the workpiece when the workpiece travels through an electrostatic flocking and an electrostatic coating chamber at high speed. A slack of the workpiece occurs due to its own weight under the influence of gravity when the workpiece travels through the electrostatic flocking and the electrostatic coating chamber at high speed. A V-shaped oblique surface portion of the workpiece is forcibly defined by a pressure roller in a position corresponding to that of the slack of the strip-like elongated workpiece. An electrode is disposed in parallel to the workpiece's V-shaped oblique surface portion defined by the pressure roller.

Abstract: A workpiece is passed at high speed through an electrostatic flocking chamber provided with an inlet opening and an outlet opening, a distance between which openings is increased to realize optimum flocking conditions for the workpiece being electrostatically flocked. In order to conduct an electrostatic flocking operation of the workpiece by having the workpiece traveled at high speed between the inlet opening and the outlet opening, a pair of electrodes are disposed parallel to a passage of the electrostatic flocking chamber, which passage is increased in length to permit the workpiece to pass through the passage at high speed. A high voltage is applied to a first one of the electrodes, while a low voltage lower than the high voltage is applied to a second one of the electrodes, wherein the first and the second electrode are disposed in the inlet opening's side and the outlet opening's side, respectively.

Abstract: An electrostatic flocking apparatus has a flocking chamber, an air flow producing device for supplying and discharging air into and out of the flocking chamber, a filter for allowing the air out of the flocking chamber, but preventing the fibers from being discharged out of the chamber, an air box at the bottom of the flocking chamber and having a perforated board or wire mesh, electrodes, power sources electrically connected to the electrodes, a support for supporting the workpiece and a conveyor for conveying the work into and out of the flocking chamber.
