  • Apparatus for piecing yarn to broken end of a fibrous strand in a spinning machine
    Patent number: 4485615
    Abstract: According to the method of the invention, the broken end of yarn and the end of the fibrous strand are caused to move simultaneously opposite to one another and, after the ends of yarn and the fibrous strand are brought close together, they are caused to deviate from the path of their initial movement and to run at a distance from one another in such a manner that during the untwisting of the end of yarn it engages the end of the fibrous strand to form a knot. In an apparatus for carrying out the method for piecing the end of yarn to the end of the fibrous strand, there is provided a device for gripping and transferring the end of yarn to the pulling device, which is formed by a pipe having an outlet pipe connected to a source of reduced air pressure.
