Title: Coating conducting surfaces with fibre flocks - by introducing fibres decelerated to zero speed into the electrostatic field
Inventor: MUELLER JOACHIM
IPC: B05B7/14
Filed: 1975-07-28
Abstract: A carrier material e.g. paper, textiles, metal, or plastics treated with an electrically conductive adhesive is coated electrostatically with the fibrous flocks which are introduced into a high voltage chamber. In the chamber, the speed of the flocks is reduced so that at the time they reach the side of the chamber facing the material to be coated, it is zero. Due to a difference in potential between chamber and the material with the adhesive, the flocks are accelerated and embed themselves in the adhesive. Ensures that the fibres applied stand vertically on the ground material and can be laid on at any desired density, whilst the monofilament flocks can be longer than is possible in other processes.
