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).
