PROBLEM TO BE SOLVED: To obviate the defects of the conventional electromagnetically selective operation system for controlling dobby and other weaving mechanism by forming each revolving selector in such a manner that an amplitude of motion is given to the selector to enable distinctive and accurate movement of the selector despite an extremely reduced interval. SOLUTION: Each selector 7 is provided with a movable armature 12 pivotally attached to the selector on its end toward its rotational axis; a releasing elastic means 13 is formed so as to act on the end opposite to the movable armature 12 in order to allow the movable armature 12 to constantly abut against the magnetic pole 6a which corresponds to the electromagnetic fixed armature 6a, 6b. The selector 7 is returned to its releasing position by the counteraction of the elastic means 13, and as the portion on the opposite side of this selector 7 is released from the other magnetic poles of the fixed armatures 6a, 6b, an interval necessary for the unit to function is created. |
