The present invention relates to a pulse device for dobbies having swing-out outlet levers and oscillating drivers, which is intended for controlling heald frames on weaving machines. The object of the invention is to provide, for a dobby having swing-out outlet levers, a pulse device of this type which contains no movable electromagnets and which ensures a reliable switching of the desired function along with an increased rotational speed of the weaving machine, whilst the number of elements of the pulse device is to be minimal and the pulse device is simple from the point of view of both design and production. According to the invention, the output signal from the control part passes to an immovable electromagnet which is assigned a reversible straightedge for controlling two stops which are assigned to a control lever connected by means of a tension rod to a balance lever of articulated differentials which control the stops of the change-over switches. |
