Abstract
A spindle of an airjet spinning machine for guiding back the free yarn end after an interruption in a spinning process is disclosed. The spindle contains an injector duct in the immediate vicinity of the spindle orifice. To guide the free yarn end back after an interruption, compressed air is admitted through the injector duct and generates a suction action at the spindle end. After the yarn end has been guided back level with the entrance of the injector duct the yarn end is blown out of the spindle orifice by the compressed air.
