Abstract
A heald shaft (1) for coupling the shaft rods (2) with the end binders (5), having connecting joints or hinges (10) whose pivot axes (14) lie externally of the shaft rods (2) and preferably inside the end binders (5). Due to 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). Preferably, the driving couplers (7) are arranged above the end binders (5) in a direct extension thereof.
Claims20
A heald shaft for weaving machines, comprising
- a shaft rod which supports healds for forming sheds,
- an end binder surrounding an inner space and, a connecting joint connecting an end of the shaft rod to the end binder, with the connecting joint including
- a pivot connecting joint member rotatable mounted on the end binder at least partially within the inner space for rotation about a pivot axis and having a bar that extends out of the inner space and is connected there to the end of the shaft rod and connecting the shaft rod and the end binder to one another so that the end binder and the shaft rod can pivot relative to one another,
- wherein the pivot axis is situated externally of the shaft rod, and
- wherein the connecting joint is free from resetting forces tending to oppose relative pivotal motion between the shaft rod and the end binder.
