Abstract
A method and an apparatus for continuously unwinding a yarn from a yarn package which may be associated with a method and apparatus for texturing the withdrawn yarn. The yarn is withdrawn from a feed yarn package supported in a creel, and the trailing yarn end of the feed yarn package connects to a leading yarn end of a second feed yarn package (reserve package) by a knot-type piecing to achieve a continuous advance of the yarn for its treatment or processing. A sensor is provided which detects and signals the yarn change from the feed yarn package to the reserve package after the feed yarn package is unwound, and the signal may be used to control the texturing process.
