Method of and apparatus for dispensing wire from a wire storage spool

摘要: A method of and apparatus for dispensing wire from a massive storage spool make use rotary support holding the in bearing contact therewith. The comprises pair rollers, one which is rotationally driven by motor to turn whereby permit be unwound therefrom. subject traction force applied capstan pinch roller advance between outlet guide rollers into utilization zone, e.g. cutting zone wire-cut EDM machine. sensor provided detect deviation tension guides predetermined value. output servo control circuit rotating so as maintain constant. support, are carried on wheeled carrier also enclosed within an electrical shield prevent emission noise produced therein.
