The measuring device is used for measuring lengths of thread, for example for measuring weft thread for a weaving machine. The measuring device includes a constantly rotating winding body or drum and a thread guide which is adjustable longitudinally of the drum. The thread guide is spaced from the drum and has one or more guide surfaces formed by eyelets or a comb. By shifting the thread guide axially of the drum, the length of thread in the windings on the drum can be increased or decreased per unit time during operation.
