Abstract
A stopping mechanism includes a brake device for an insertion device and a detector for determining the position of the insertion device. The detector includes a sensor which subjects the insertion device to electromagnetic radiation in the microwave range and operates on the Doppler principle. The position of the insertion device is determined by counting the number of crossover points of the Doppler signal in relation to a reference position. The detector has a high degree of resolution and is particularly suitable for looms using gripper shuttles. It is also highly flexible in the location in which the sensor may be arranged in the stopping mechanism.
