Heald shaft for a weaving machine

Abstract

For a releasable attachment of shaft staves (8) to shaft rods (2) of a heald shaft (1) of a weaving machine, holding devices are provided which, for example, are composed of two sheet metal members, of which one part forms an adhesive surface for bonding to the shaft rod (2). The part that remains free serves for receiving respective metal reinforcing strips (rib (31, 32)) which may be riveted or welded to the sheet metal members. The reinforcing strips serve for receiving securing elements for a bracket and for positioning the latter. In this manner the positioning is effected in a form-fitting manner. The sheet metal members are tightened against the bracket preferably by bolts for firmly clamping the bracket in the position determined by the form-fit. In the alternative, rivets may also be used which, when required, may be released, for example, by pushing them out with simple tools. The reinforcing strips are configured and secured to the sheet metal members in such a manner that the reinforcement serves at the same time for the exact positioning of the bracket (22), for preventing, by a form-fit, a vertical shift of the bracket during operation of the heald shaft.
