Abstract
A device for driving harnesses of weaving machines includes at least two driven cam shafts and at least one pair of conjugated cams connected to each other for each shaft. Swivel mounted levers which swivel about a common shaft are mounted alternately and in an opposite sense in relation to adjacent levers, each lever including two cam followers which operate with one of the conjugated cam pairs to provide a positive cam drive for the lever so that the lever oscillates. A transmission converts the oscillating motion of the levers into an up and down of the harnesses.
