Abstract
Roving bobbins of a weight of about 5 kg, by contrast to standard bobbins with weights up to 3 kg, can be used in a spinning system in which the flyer frames are of the multi-axial drive type and are equipped with an automatic bobbin change mechanism which transfers the full bobbins to suspension carriage trains displaced thereby to ring-spinning machines and wherein the suspension carriage trains pass into the creels of the ring-spinning frames directly or are transferred from such suspension carriage trains to the creels.
