Abstract

A lifter rod actuates controllable yarn reserve devices of an open-end spinning machine. A reciprocating device for the lifter includes a shaft supported in the frame of the spinning machine and driven at a given angular velocity. A swash plate disposed on the shaft revolves at the given angular velocity. The swash plate has a circular-annular bearing with an outer ring being rotatable relative to the swash plate. The outer ring has an articulated coupling for mechanically jigging the lifter rod. A mechanical operative connection connects the articulated coupling with the lifter rod. The shaft, the swash plate, the bearing, the outer ring, the articulated coupling, the mechanical operative connection and the lifter rod form a mechanical operative chain. A jigging amplitude control device is diposed in the mechanical operative chain and firmly connected to and supported in the machine frame.
