Abstract
An automatic control system for an electronic rotary dobby, has a pair of permanent magnets mounted on each of the corresponding rocker members. These members are driven by the dobby operating crank arms, such as the ends of the main levers. The magnets on the pair mounted on the rocker members are arranged such that in one end-of-rock position of the respective rocker member only one magnet cooperates with a related fixed sensor, and in the other end-of-rock position of the respective rocker member only one magnet cooperates with another related fixed sensor, and in the other end-of-rock position only the other magnet of the pair cooperates with its own fixed sensor. The sensor signals are compared with the corresponding signals of the predetermined weaving program, the loom being halted if they do not coincide.
