The additional roving guide in the break draft zone guarantees faultless, precise integration of the filament on the Ring Spinning Machine. On the ComforSpin® machine precise guidance of the roving is ensured by the compacting zone. The fiber package is combined with the filament immediately before the nip roll. Guidance of the filament over the feed roller can be adjusted exactly by means of a centering screw.

Process control

The roving stop mechanism ensures immediate interruption of roving feed in the event of a filament break. This prevents the production of yarn without filament.
