Abstract
The heald shaft (1) according to the invention has, for coupling the shaft rods (2) with the end binders (5), connecting joints (10) whose pivot axes (14) lie externally of the shaft rods (2) and preferably inside the end binders (5). By means of the connecting joints (10) a moment-free coupling between the shaft rods (2) and the end binders (5) is ensured. The relative pivotal motions between the shaft rods (2) and the end binders (5) appearing during operation do not generate any moment transmissions between the shaft rods (2) and the end binders (5). According to a preferred embodiment, the driving couplers (7) are arranged above the end binders (5) in a direct extension thereof.

A heald shaft (1) for weaving machines, comprising
- a shaft rod (2) which supports healds (8) for forming sheds,
- an end binder (5) surrounding an inner space (21) and connected with the shaft rod (2) and
- a connecting joint (10) disposed between the end binder (5) and the shaft rod (2) for connecting them to one another,
- wherein the connecting joint (10) defines a pivot axis (14) which is situated externally of the shaft rod (2) and
- wherein the connecting joint (10) is free from resetting forces regarding its pivotal motion.
