Abstract
The dobby according to the invention comprises, at the level of each of its blades, an oscillating piece associated with an actuation element, at least one mobile coupling member borne by the actuation element and two pivoting levers subjected, on the one hand, to the action of a reading device and, on the other hand, to that of elastic means which tend to engage catches of the pivoting levers either with a jamming surface provided on the actuation element, or with the coupling member, while the lever in engagement with the jamming surface is out of range of a selector of the reading device. In addition, mechanical members independent of the reading device are adapted to displace, against the action of the elastic means, a lever whose catch is not in engagement with the jamming surface, with the result that it does not interfere with the angular displacement of the selector.
