High-speed wire coating device and method

A device for continuously depositing a treatment substance on the surface of a moving thread, the device comprising:

• a tank configured to contain a liquid solution of the treatment substance, wherein said liquid solution is used to deposit the treatment substance on the surface of the moving thread;
• a pump configured to draw up said liquid solution from said tank and pressurize said liquid solution;
• a pressurized chamber comprising an inlet, a central channel and at least one nozzle, wherein said inlet is coupled to said pump, wherein said pressurized liquid solution is supplied by said pump to said pressurized chamber through said inlet, wherein said at least one nozzle is directed to spray said received pressurized liquid solution towards the moving thread in a form of jets with a spray velocity, wherein said jets converge on the moving thread to adjust a thickness of said liquid solution remaining on the moving thread by removing excess liquid entrained by the moving thread, wherein the moving thread runs through said central channel of said pressurized chamber at a run speed, and wherein said pump is configured to regulate said spray velocity according to said run speed of the moving thread so as to adjust thickness of said liquid solution on the moving thread to a thickness ‘e’ after passing said at least one nozzle;
• a treatment apparatus arranged downstream of said pressurized chamber such that the moving thread runs therethrough, wherein said treatment apparatus is adapted to solidify the treatment substance contained in said liquid solution onto the surface of the moving thread;
• and
• at least one motorized pulley arranged to guide and run continuously at said run speed the moving thread through said tank, past said jets, and through said central channel of said pressurized chamber and said treatment apparatus, wherein said running speed of the thread is preset and controlled.
