Abstract
An apparatus for repairing a yarn break includes a housing which is first positioned roughly by being guided towards the stop motion wire belonging to the broken warp yarn. After the broken warp yarn has been removed, a fresh separate warp yarn is introduced into the stop wire and a heddle by a pair of laterally slotted threading in tubes. In the process, the fresh warp yarn travels from a blowing opening of one tube into a suction opening in the other tube while passing through an opening in the respective stop motion wire or heddle. During this operation, the tubes are moved stepwise in the warp direction of the weaving machine until reaching a guide inserted through the reed and into which the fresh warp yarn is finally threaded.
