Abstract
A control apparatus for the electromagnetic brake of a brake device or unit of a weaving machine or loom comprises a cam-controlled brake-pulse transmitter rotating with the machine shaft and two continuous signal switching stages which act upon two parallel connected AND-gates or circuits, each having connected thereafter an adjustable or regulatable time-delay element. The latter jointly cooperate with an OR-gate or circuit which delivers a related stop signal to the brake device or unit. In this way it is possible to achieve a simple, precise and reliable regulation of the angular position of the crank, so that the regulatable time-delay between the output pulse of the AND-gate and the output pulse of the time-delay element constitutes a measure for the corresponding angular position of the crank.
