A textile storage feeding device having a pair of spaced upper and lower strand storage drums coaxially mounted integrally with one another and with a driving pulley assembly for integral rotation for transiently storing a traveling textile strand windingly in sequence about the upper storage drum and then about the lower storage drum. A stop motion arm monitors the traveling strand intermediate the storage drums to detect upstream strand breakages, the stop motion arm being isolated from tension variations, flutterings and the like in the traveling strand to avoid "false stops". Another stop motion arm upstream of the storage drums monitors increases in the tension of the strand, without detecting strand breakages or other tension losses, to stop operation in response to excessive strand tension to prevent at least some strand breakages.
