Abstract
A positive eccentric dobby having a rigidly mounted roller lever shaft with minimal clearance, on which pivoted roller levers are disposed, which transmit the movement to the heald frames via coupled connecting rods, reversing levers and rods. A camshaft with eccentrically disposed cam discs is rigidly mounted on a displaceable carriage. In the state where there is a clearance between the rollers and the cam discs, one or more stops swivel the roller levers so that the heald shafts can be coordinated in several preset positions. When there is no clearance between rollers and cam discs, a jamming block having a motorized driving device fixes the position of the carriage with a stop.
