A fault pre-warning device for use in tufting machines has a switching strip (11) over which the carpet web is guided in such a way that the switching strip (11) is acted on by a defined force in the switching direction. On the occurrence of excessive tension in one or more of the warp threads the switching strip (11) initiates a switching process.
