Abstract
A texturing machine for producing a crimped yarn and which has a plurality of serially arranged yarn processing units leading to a takeup device. A threading device is provided for threading a yarn for the first time before the start of a process. For this purpose, the threading device comprises at least one guide tube and an air injector connected thereto, with the guide tube including a suction inlet for receiving the yarn. In accordance with the invention, a cutting device is arranged in the region of the suction inlet of the guide tube, with the cutting device cutting the yarn while being threaded into the suction inlet.
Claims16
A yarn texturing machine comprising
- a plurality of yarn processing units which are serially arranged along a yarn path of travel leading to a takeup device,
- a threading device for initially threading a yarn along at least a portion of the path of travel, said threading device comprising a guide tube and an air injector connected to the guide tube, with the guide tube including a suction inlet for taking in the yarn and a blow outlet for ejecting the yarn, and
- a cutting device positioned adjacent the suction inlet for cutting the yarn while it is being initially threaded into the suction inlet.
A method of threading an advancing yarn onto a texturing apparatus which comprises a plurality of yarn processing units which are serially arranged along a yarn path of travel leading to a takeup device, comprising the steps of
- positioning a guide tube along a portion of the yarn path of travel and generating an air flow within the tube so that the tube defines a suction inlet and a blow outlet,
- engaging the advancing yarn with a yarn guide and moving the yarn guide and the engaged yarn to a threading position immediately upstream of the suction inlet of the guide tube and so that the yarn is cut by a cutting blade with the cut end being engaged by the suction effect at the suction inlet of the guide tube.
