ABSTRACT:
After forming a package on a spindle from a roving fed to the spindle through a rotatable flyer finger, feed of the roving is stopped to arrest the flyer in a position with the finger anywhere on the package underneath the upper end of the last layer of turns formed on the package. The package is then lowered until the finger is above the upper end of the last layer of the turns formed on the package while the package is rotated in a reverse direction opposite to the forward direction without feeding more roving to the package. The package is rotated in the forward direction through at least one half revolution about the axis without feeding more roving to the package so as to form at least a partial loop of the roving around the package above the upper end of the last layer of the turns and then more roving is fed to the package while same is lowered until the finger is below the upper end of the last layer of the turns. Finally the package is raised to sever the roving upstream of the package.
