Spinning frame has automatic means to pick up and twist a broken strand end while feeding it, preferably axially, e.g. to a knotter to be joined to an end from a bobbin being wound up by a ring and traveller, or to a fresh bobbin. The twist is preferably inserted into the strand, e.g. from drafting rolls, by passing the strand through a bore in the nozzle to which pressurised fluid is supplied in a vertical path, preferably from a number of circumferentially spaced bores intersecting the strand bore tangentially and inclined rearwardly to create a low pressure area drawing the strand into the bore.
