Spinning plant with roving frames and ring-spinning frames

摘要

A spinning plant having one or more roving frames and one or more ring-spinning machines coupled by a common transporter has bobbin/core transfer units equipped with a color sensor which ensures that color coded cores representing particular roving qualities are replaced by full bobbins of the respective quality and vice versa, thereby avoiding problems of feed of the incorrect roving quality to a spinning machine and the winding of roving incorrectly on a color-coded core.
