An automatic control system for an electronic rotary dobby, consisting of a pair of permanent magnets (19,20) mounted on each of corresponding rocker members (3) driven by the dobby operating crank arms, such as the ends of the main levers, the magnets of the pair being arranged such that in one end-of-rock position of the respective rocker member only one magnet cooperates with a relative fixed sensor (21,22), and in the other end-of-rock position only the other magnet of the pair cooperates with its own fixed sensor, the signals of the sensors being compared with the corresponding signals of the predetermined weaving program, the loom being halted if they do not coincide. <IMAGE> |
