Abstract

Traversing yarn guiding rods in textile machines producing X-packages are often made of carbon fibers for the purpose of reducing the inertia force. These kinds of traversing yarn guiding rods are prone to wear at their bearing points. For this reason, the bearings, having a distance to one another which corresponds to at least twice, preferably three times the traversing stroke, are collectively replaced from time to time, in such a way that the yarn guide rod is supported at different places than before. The replacement bearings are applied staggered to the old bearing points in such a way that the new bearing points now have a distance to the exposed previous bearing points, which distance corresponds to at least one traverse stroke. This results in the replacement bearings acting with a non-worn part of the fiber guiding rod. The life of the yarn guiding rod is thus significantly increased.
