Claim 4:
5. A drafting system for a spinning machine, comprising a drafting system unit, which has at least one weighting arm, which is pivotable between an operating position and an open position by a repositioning device,
characterized in that:
the at least one weighting arm is connected to a retaining rod for conjoint rotation, which retaining rod is mounted on a retaining rod holder for rotation about the longitudinal axis of the retaining rod by the repositioning device, characterized in that the repositioning device has a knee lever assembly, which is operatively connected to the retaining rod and which is repositionable between a closing position associated with the operating position and an opening position associated with the open position, characterized in that the knee lever assembly has a first knee lever and a second knee lever,
the first knee lever being pivotable about a first joint axis, which is stationary relative to the retaining rod,
the first knee lever and the second knee lever being articulated to each other by a knee lever joint axis, and
the second knee lever having a knee lever portion spaced apart from the knee lever joint axis, which knee lever portion is connected to the retaining rod so as to transmit a rotational motion.
