Abstract
A device for pneumatically conveying and guiding a multifilament thread has a closed conveying channel which has a thread inlet opening at one end and a thread outlet opening at the opposite end. An injector zone having at least one compressed air channel which opens into the conveying channel is formed between the thread inlet opening and the thread outlet opening, wherein the compressed air channel can be connected to a compressed air source. In order to avoid blowing air from flowing back from the injector zone at the thread inlet opening, a return flow channel is formed in a channel section of the conveying channel between the thread inlet opening and the opening of the compressed air channel, which return flow channel connects the conveying channel to ambient atmosphere.
