  • Patent number: 6332312
    Abstract: The invention relates to a method and device for spinning with a suppressed yarn balloon (75), whereby the rotation of the yarn is predominately produced between a top spindle (2) and the clamping gap (523) of delivery rolls (521, 522) at the exit of the drafting system (5). The top spindle (2) is provided with one or a plurality of projecting parts in the head area thereof and extends with said projecting parts on the elongated axis of the spindle (1) from underneath up to a vertically displaceable yarn guide (3). The vertically adjustable yarn guide is displaced upwards and away from the top spindle in order to prepare an automated feed package changing. Afterwards, the ring tail (4) is lowered into the underwinding position. The aim of the invention is to provide a method which can also be used for flat and very fine yarns, especially combed yarns. To this end, the extended slubbing (71) which exits the drafting system is compacted while the yarns are maintained in a parallel position.

  • Patent number: 6324825
    Abstract: A drafting frame for a spinning machine, especially a ring-spinning machine can be readily retrofitted with a compaction device adjacent the last pair of drafting rollers if the condensing zone is defined between a clamping location formed by the nip of the last roller pair and a clamping location formed by a number of elements of the compacting device against the upper roller of the last roller pair.
