Abstract
The heald shaft (1) for weaving machines is divided into a machine-resident frame part (14) and a removable frame part (15). While the removable frame part (15) supports a heald mounting rail (30) that must be released from said frame part for a heald change, said removable frame part is associated with an additional heald mounting rail (33) that is releasably held on the lower shaft rod (16). The upper shaft rod (25), together with the two heald mounting rails (30, 33), forms a removable frame part (15). The lower shaft rod (16), together with the lateral supports (19, 20), forms a machine-resident frame part. Preferably, the lateral supports (19, 20) and the lower shaft rod (16) are rigidly connected to each other.
Claims5
Heald shaft for weaving machines, comprising:
- a machine-resident frame part that is to be mounted to the weaving machine, and
- a removable frame part that is detachably connected to the machine-resident frame part and complements the machine-resident frame part (14) to form a complete rectangular frame;
- and wherein
- the machine-resident frame part comprises a first shaft rod and two lateral supports that are connected to each other to form a U-shaped frame part,
- the removable frame part comprises only a second shaft rod that is releasably connected to the lateral supports,
- a first heald mounting rail is supported on the removable frame part,
- a second heald mounting rail is connected to the machine resident frame part via a releasable coupling means, and
- means, in addition to the lateral supports, for connecting the second heald mounting rail and the removable frame part, whereby the removable frame part and the first and second heald mounting rails can be separated as a unit from the machine resident frame part, which can remain mounted on a weaving machine, when the releasable connection between the second shaft rod and the lateral supports and the releasable connection of the coupling means are both released.
