Abstract:
A method for operating a work station of a bobbin winding machine having a yarn tension sensor connected to a control device for monitoring the yarn tension of a yarn running from a delivery bobbin to a take-up bobbin, a yarn tensioner for regulating the yarn tension, a splicing device for the automatic connection of a first yarn end of the delivery bobbin with a second yarn end of the take-up bobbin following a yarn break or a yarn cleaning cut, and a delivery bobbin exchange device for exchanging delivery bobbins which cannot be further unwound, the method comprising the steps of monitoring an actual value of the yarn tension by means of the yarn tension sensor after connecting the first yarn end with the second yarn end, and actuating the delivery bobbin changing device by the control device to replace an existing delivery bobbin with a fresh delivery bobbin if the actual value of the yarn tension exceeds a predeterminable threshold tension value.
