<p>A yarn feed arrangement (10) for a tufting machine is provided in which the feed of yarn to needles is directed by optical detectors (18). The detectors (18) are linked to a display providing a visual indication of whether there is a fault or no-fault in the feed to one or more of the needles. The display can be incorporated in a central control computer in which the stitching requirements to produce predetermined patterns can be stored and the signals produced by the detectors (18) compared with the standard requirements to ensure accurate production of the required pattern.</p> |
