ABSTRACT:
A yarn-body core is supported by an upright spindle adjacent a vertically displaceable yarn guide through which a yarn to be wound passes to the core. The core and spindle are rotated and simultaneously the guide is displaced upwardly along the core to wind the yarn on the core until an instant when a yarn package having a predetermined size is formed on the core. Thereafter the guide is lowered to a level below the core while the spindle continues to rotate to wind several turns of the yarn on the spindle below the core. The rotation rate of the spindle and the core is decreased to a relatively low level prior to the instant when the yarn package is completely formed and thereafter this rotation rate is decreased to a standstill in accordance with a predetermined program starting at the instant the yarn package is fully formed and ending when several turns have been wounded on the spindle.
