Abstract
The eccentric drive for moving the heddle frames between a top shed position and a bottom shed position is constructed to form symmetrical sheds not only for large frame movements but also for small frame movements. In one embodiment, the link between the cam-actuated lever and the deflecting lever is pivoted on the deflecting lever and secured to one of a plurality of positions on the cam-actuated lever. These positions are located on a curved line which has a center of curvature located away from the axis on which the link is mounted on the deflecting lever. These positions are formed by a toothing, a row of apertures or an elongated slot.
