  • Drafting frame for a spinning machine
    Patent number: 6604261
    Abstract: Downstream of the last roller pair of a drafting frame for a spinning machine, the roving is condensed in a fiber-bundling zone having a belt with perforations to which suction is applied. Another belt converges toward the belt with the perforations and engages the roving at a nip spaced from the nip formed by the last roller pair of the drafting frame so that the wedge-shaped converging of the two belts promotes the compacting or condensing action.
    Type: Grant
    Filed: June 6, 2002
    Date of Patent: August 12, 2003
    Assignee: Zinser Textilmaschinen GmbH
    Inventors: Angelika Stoll, Daniel Friedrich

  • Drafting frame for a spinning machine
    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.

  • Method of operating a ring-spinning machine with vertically shiftable thread-guide eyes
    Patent number: 6009698
    Abstract: Thread breakage rates of a ring-spinning machine are measured successively and/or from different zones at the spindle stations and a thread guide between a headpiece of each spindle and the output rollers of the drafting frames can be vertically adjusted in response to a difference in the thread break rates.
