Abstract

A multitude of heald shafts can be decoupled simultaneously as a set. For this purpose one of the two coupling sections (2, 3) of a shaft, either the section on the push rod side or the section on the shaft side, is equipped with a decoupling mechanism (11). All decoupling mechanisms (11) are power operated in unison by hydraulic, pneumatic, or electrical power. The power operated decoupling mechanisms operate a spring biased rocker lever (7) of a lever mechanism (6) to decouple the coupling sections from each other.
