ABSTRACT:
A method and apparatus for electrostatically flocking a thread-like or yarn-like material. This material rectilinearly and continuously or intermittently is moved through an electrical field which is generated between electrodes having non-planar yet symmetrical potential surfaces. This electrical field preferably is generated between curved potential surfaces of the electrodes. The flock is shot into the adhesive coating of a given thread not only radially but also at an angle. The thread does not have to be turned. As a result, a dense and improved flocking is achieved all around the yarn or thread in a simple and economical manner.
