DISPOSITIVO DI CONTROLLO DELLA VELOCITA PARTICOLARMENTE PER MACCHINE TRECCIATRICI EPROCEDIMENTO PER IL CONTROLLO DI UNA MACCHINA TRECCIATRICE

摘要

The present speed control apparatus and method operates to progressively increase the speed of travel of the strand supply carrier shuttles of the braiding machine as the amount of strand material wound on the supply carriers is decreased and to thereby increase the efficiency of the braiding machine. The speed control includes an ultrasonic sensor supported adjacent the path of travel of the strand supply carrier shuttles and being operable to detect the amount of strand material remaining on the strand supply carriers during each serpentine path of travel of the strand supply carriers past the sensor. Computers are provided for progressively increasing the speed of travel of the strand supply carrier shuttles in response to detected decreases in the amount of strand material on the strand supply carriers.
