<p>Double-lift dobby without auxiliary springs comprises lifters which are controlled by counter moving lags and connector which is guided about a movable roller. Each lifter has at its end remote from the hook, a transverse lever with support zones for abutment against transverse stop surfaces of stationary stops. The free ends of the connector extend between the stops and are connected to the lifters at connecting points disposed between the support zones. The roller is biassed by a return spring in a manner which causes mutual abutment of the support zones against the stop surfaces. The lifters can be pivoted about a pivot point formed by abutment of the lever against the stop out of the lag-engaging position against the bias of the spring.</p> |
