ABSTRACT:
A method and apparatus for controlling a winding station of a bobbin winding machine when changing a take-up bobbin includes driving the take-up bobbin by contact with a yarn guide drum depositing a yarn, and bringing the take-up bobbin to a standstill by controlled deceleration of a rotary speed of the yarn guide drum after ascertaining that a predetermined yarn quantity has been reached, until the yarn guide drum comes to a standstill. This is done while producing a varying slip between a surface of the yarn guide drum and a surface of the take-up bobbin effecting ribbon prevention but being limited to avoid knocking the yarn off the bobbin and damage to the surface of the bobbin. A winding station of a bobbin winding machine includes a yarn guide drum driving a take-up bobbin by contact while depositing a traveling yarn on the take-up bobbin. A drive mechanism for the yarn guide drum has a rotary field motor. An electronic yarn cleaner monitors the traveling yarn. A measuring device detects attainment of a predetermined yarn quantity and outputs a signal. A circuit is activated by the signal for reducing a rotary field frequency of the rotary field motor down to 0 Hertz in increments.
