Abstract
After winding of a thread into a package, the thread is severed and, in order to prevent whirling of the thread end around the package, the end portion is interlaced with the package surface during the braking phase of the package. Interlacing is performed by blowing pressure jet against the thread end and the package surface within an interlacing chamber defined by a pivotally mounted shoe from which the pressure jet is emitted.
