Abstract
A profile rod (15) preferably consisting of an extruded aluminum profile has lateral walls (18, 19) that have two snap-in zones (25, 26) that project toward each other and extend parallel to each other over the entire length of the profile rod (15) and that are located on the same height. The distances of the two snap-in zones (25, 26) from the closest strip (21) correspond to each other. In this manner, the profile rod (15) may be made extremely thin-walled, on the one hand, and offers possibilities for fastening profile pieces that permit the input of larger forces into the profile rod (15) as well as the output of such forces therefrom, on the other hand. This concept offers a basis for the construction of light-weight heald shafts that can still handle great loads.
Claims15
A profile rod for a shaft rod of a heald shaft, said profile rod being configured as a hollow profile with opposed lateral walls which delimit between them at least one hollow space, and
- wherein opposed the lateral walls have outside surfaces with respective strip-shaped snap-in zones located opposite one another, with inner surfaces of the lateral walls within the snap-in zones extending inwardly to provide a spacing between the inner surfaces in the snap-in zones that is smaller than the spacing between the opposed inner surfaces in the remainder of the hollow space.
