ABSTRACT:
A dobby for controlling movements of a heald frame in a weaving machine is provided. A treadle is mounted on a treadle spindle and a link arrangement connects the treadle to the heald frame. Levers are mounted on the treadle and catching members are arranged on the levers and on the treadle. The catching members on the treadle interact with a corresponding catching member on one of the levers based on a control signal. Driving equipment moves the levers between a central position and an outer position. The treadle follows the movements of the lever it is connected to by the catching members and moves the heald frame via the link arrangement.
