Abstract
A method and device for determining the orientation of a cross-wound bobbin tube () having a yarn draw-off end face () configured as a tube tip () with a beaded edge () and an opposite end face () configured as a tube foot () without a beaded edge (). A digital image of an end face () of the bobbin tube () is detected, the digital image is subjected to an edge detection to determine the object edges () of the tube (), a recognition parameter dependent on the width (b, b) of the circular ring () formed by the object edges () is determined, this recognition parameter is compared with a reference value and a conclusion is drawn about the orientation of the bobbin tube () depending on the result of the comparison.
