Abstract (en)
[origin: US4385588A] A device for depositing an electrifiable material, e.g. cut strands, fleece, flock, upon an adhesive-coated surface comprises a vibrating sieve which is formed by a multiplicity of cylindrical parallel elements in line contact along respective generatrices and in line contact with an enclosure. In the interstices between these elements the electrifiable material passes through a grid on the bottom of this sieve which is connected to a high voltage source so that electrostatic forces assist in a transfer of the material to the adhesive. The application pattern is determined by a mask on the upper portion of the sieve and a complementary mask on a similar sieve through which excess particles are evacuated from the application region.
