METHOD AND APPARATUS FOR GENERATING AN ELECTROSTATIC FIELD FOR FLOCKING A THREAD-LIKE OR YARN-LIKE MATERIAL, AND THE FLOCKED ARTICLE THUS PRODUCED

摘要

ABSTRACT OF THE DISCLOSUREA method and apparatus for electrostaticallyflocking a thread-like or yarn-like material. Thismaterial rectilinearly and continuously or inter-mittently moved through an electrical field whichis generated between electrodes having non-planar yetsymmetrical potential surfaces. This electricalfield is preferably generated between curved potentialsurfaces of the electrodes. The flock is shot intothe adhesive coating of a given thread not onlyradially but also at an angle. The thread does nothave to be turned. As a result, a dense and improvedflocking is achieved all around the yarn or threadin a simple and economical manner.
