Abstract
A device for retrieving the end of yarn wound on a yarn-feed spool includes a system for blowing an essentially tangentially directed current of air over a rotating yarn-feed spool so that an end of the yarn wound on the yarn-feed spool can be freed from the spool. A suction nozzle is provided to capture and draw into the nozzle the end of the yarn blown free from the spool. A movable carriage system carrying at least the air current generating means and the suction nozzle is provided so that a yarn-feed spool can be approached, exposed to the air current and the freed yarn end captured by the suction nozzle. The mobile system may also carry a device for engaging the driving the yarn-feed spool in rotation. A conveyor system for moving the retrieving system over a weaving machine is also described.
