The method includes a step of drawing the sliver to the form of a drawn roving having the yarn fineness and strengthened by a twist, a step of centrally guiding the yarn being produced by a guide means before its entry on the rotating working surface for guiding the yarn by the effect of centrifugal forces to a traveller arranged at its edge and carried by the working surface, by which the yarn is guided during its transport out of contact with the working surface for being wound on the rotating spool, the axial position of which with respect to the edge of the working surface is changing during the winding-up, wherein the yarn circles during the guiding along the working surface of a single rotating carrier the rotating spool with the wound-up yarn with a higher frequency. The apparatus comprises a drawing device (1), an guiding eyelet (2) arranged centrally on the axis of the spindle, a rotating carrier of the working surface (5) surrounding the spindle (19) and carrying at the edge of the surface a traveller (12), a device for setting the mutual axial position of the edge of the working surface and of the tube (22) mounted on the rotating spindle, wherein the rotational movement of carrier (6) of the working surface (5), is coupled with the rotational movement of the spindle so as to have a higher angular speed of rotation.
摘要:
Until now, ring spinning machines have produced the best yarn in terms of yarn strength and textural characteristics, but have been slower, less productive, and more costly than some of the newer high-speed spinning machines, such as open-end spinning and air-jet spinning. Still, since these newer spinning machines have not been able to mimic the characteristics and benefits of ring-spun yarn, their application has been limited. One main problem has been the impossibility of measuring yarn tension during spinning. The present invention solves the problem by providing a tension sensor 15 that detects the tension of the yarn Y between the drafting mechanism 101 and the bobbin 6. The tension sensor 15 contacts and receives pressure from the yarn Y, and a sensor main body 51 detects the yarn tension. Ideally, the angle of the bend in the yarn Y at the point where the yarn Y meets a head unit 52 is between 130 degrees and 170 degrees.

Die Spinnmaschine enthält eine größere Anzahl von in Reihe nebeneinander angeordneten Arbeitsstellen, von welchen jede eine auf einer Spindelbank (21) angeordnete Spindel (2), sowie auch ein die Spindel (2) umschließendes Organ (3) für die Garnführung enthält, das auf einer Führungsbank (9) angeordnet ist, wobei die erwähnten Bänke (21, 9) für alle in der Reihe stehenden Arbeitsstellen gemeinsam sind. Dabei sind die Spindel (2) jeweils in einem Tragkörper (4) und das Organ (3) für die Garnführung in einem zweiten Tragkörper (5) gelagert. Diese Tragkörper (4, 5) sind auf den zuständigen Bänken (21, 9) angeordnet, mit Möglichkeit sie von ihrer ersten, der üblichen Betriebslage der Spindel (2) und des Organs (3) für die Garnführung entsprechenden Lage, in ihre zweite Lage, die in Richtung nach außen von der Arbeitsstelle verschoben ist und mittels Führungsmittel gekoppelt ist, zu bewegen, wobei mindestens einer dieser Tragkörper (4, 5) in den erwähnten Lagen mittels Arretiermittel fixierbar ist.

Die Spindelspinn- oder Zwirnvorrichtung enthält eine angetriebene Spindel (4), einen ebenfalls angetriebenen Ballonbegrenzer (6) mit einer inneren Arbeitsoberfläche (17) für die Berührung mit dem Garn (P) und eine ortsfest angeordnete Begrenzungswand (25) für eine rotierende offene Schlinge (18). Die Begrenzungswand (25) ist in koaxialer Beziehung zu der Spindel (4) angeordnet und mit radialem Abstand umschließt sie das untere Ende des Ballonbegrenzers (6). Zwecks Erhöhung der Stabilität des Spinn-oder Zwirnverfahrens ist mindestens auf einem Teil der Begrenzungswand (25) eine Gleitfläche (26) vorgesehen, die sich vom Bereich der ersten Berührung des Garns (P) in Richtung zum unteren Ende der Begrenzungswand (25) von der Achse (7) der Spindel (4) entfernt.

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zur Erzeugung eines zwirnähnlichen Textilfadens, bei welchem zwei parallel laufende Faserlunten 1, 2 einem Verzug unterworfen und diese Faserlunten anschließend an einem Vereinigungspunkt 11 zusammengefaßt werden, wonach der so entstandenen vereinigten Faserlunte 12 eine Drehung erteilt wird. Hierbei wird die Drehung der Lunte 12 durch eine Spindel 13 und eine im wesentlichen frei rotierbare Glocke 25 bewirkt, die über den aus der vereinigten Faserlunte gebildeten Faden 12' geschleppt wird.
