    摘要: The invention relates to a balancing ring (1) for compensating imbalances of a spinning machine rotor (2) with balance weight elements (4) guided by a circular guidance body (3) and a supporting element (5) for arranging the circular guidance body (3) coaxially to an axis of rotation of a spinning machine rotor (2). Additionally, the invention relates to a spinning machine rotor unit comprising at least one balancing ring as well as a method for compensation imbalances of a spinning machine rotor unit utilizing at least one balancing ring. To propose a balancing ring for compensating imbalances of a spinning machine rotor which can be easily and cost-efficiently produced and which is self-balancing without any external control, the balance weight elements (4) are movable along the full circumference of the circular guidance body (3).

    摘要: The invention relates to an adjustment device as well as a method for adjusting the contact pressure applied to a tangential belt by a belt tension roller of a spinning machine between the rotors of two neighbouring spinboxes. To propose an adjustment device which allows a fast and easy adjustment without long service breaks as well as an operation of a spinning machine with reduced wearing of the tangential belt drive unit and a reduced power consumption of the spinning machine, the adjustment device comprises a measuring jig for measuring the contact pressure of the belt tension roller, the measuring jig having two rotor support plates with positioning points for reference to the rotor positions and one measuring probe with a measuring point arranged between both positioning points. The two rotor support plates are arranged in an opposing direction to the measuring probe for securing the position of the measuring jig against the pressure of the belt tension roller applied to the measuring probe at the measuring point. The adjustment device further comprises an adjustment jig for adjusting the contact pressure of the belt tension roller, the adjustment jig having at least two positioning elements for mounting the adjustment jig to the spinning machine, in particular to a wall of the spinbox opposite to the position of the belt tension roller and or the measuring jig, as well as having an adjustment mechanism for adjusting the contact pressure of the belt tension roller using a tool.

    摘要: Die Erfindung betrifft ein Verfahren zum Betreiben einer Offenend-Rotorspinnmaschine (1) im so genannten "Joint-Spinning-In"-Verfahren, wobei die Arbeitsstellen (2) der Offenend-Rotorspinnmaschine (1) jeweils einen antreibbaren, in einem unterdruckbeaufschlagbaren Rotorgehäuse (18) mit hoher Drehzahl umlaufenden Spinnrotor (8), eine antreibbare Faserband-Auflösewalze (28) sowie einen einzelmotorisch antreibbaren Faserbandeinzugszylinder (11) aufweisen.
    Um zu gewährleisten, dass auch nach einem Stromausfall beim anschließenden "Joint-Spinning-In" alle Anspinner der Offenend-Rotorspinnmaschine (1) eine ordnungsgemäße Ausbildung aufweisen, ist erfindungsgemäß vorgesehen, dass beim Auftreten des Stromausfalls die Einzugsgeschwindigkeit (45) des Faserbandeinzugszylinders (11) zunächst kontinuierlich reduziert wird, und dann die Einzugsgeschwindigkeit (45) des Faserbandeinzugszylinders (11) zur Generierung einer Faserzusatzeinspeisung in den Spinnrotor (8) kurzzeitig wieder erhöht und der Faserbandeinzugszylinder (11) dann so abrupt gestoppt wird, dass es nach der Stelle der Faserzusatzeinspeisung zu einem gezielten Abriss der Fasern kommt, wobei die abgerissenen Fasern pneumatisch entsorgt werden.

    摘要: The invention relates to a transmission unit (1) for two sequently arranged drive belts (2, 3) in a drive belt unit (12) of a machine for transmitting power to several positions, in particular to output rollers (4) of a spinning machine, as well as to a belt drive unit for transmitting power to several positions, in particular to output rollers of a spinning machine. To propose a belt drive which can be extended to any length, which reduces the transmission of vibrations along the belt and thus reducing the slippage of the long belts on the output rollers as well as which allows a simplified exchange of the drive belt and a more cost-efficient operation of the belt drive, the transmission unit (1) of the belt drive (12) comprises an input belt wheel (5) to be driven by a first drive belt (2) and an output belt wheel (6) for driving a second drive belt (3), wherein a transmission belt (7) indirectly interacting with both belt wheels (5, 6) is arranged in the transmission unit (1) so that both belt wheels (5, 6) turn in the same direction and have a transmission ratio of 1 : 1.
