  • Patent number: 5887417
    Abstract: An OE spinning apparatus 1 with a spinning rotor 2 having a hollow shaft 26 supported radially in a wedge-like gap 25 of a support-disk bearing 4 and driven by an individual motor 9 comprising an armature 11 integrated into hollow shaft 26 at its end and a stator 10 fixed to spinning-box housing 12. Pressure roller 8 rotates about axis 24 angled acutely to rotor shaft 3 to urge rotor shaft 3 into the gap 25 and also in the direction of axial bearing 13, which may be a permanent magnet bearing or pneumatic bearing. Spinning apparatus 1 thereby has a high natural frequency, which makes possible very high rotor speeds.

  • Patent number: 5289675
    Abstract: A pot spinning assembly comprises a spinning pot and a yarn guide extending into the spinning pot. A controlled drive causes a relative motion between the spinning pot and the yarn guide during a spinning process. Yarn is deposited in layers on the inner wall of the spinning pot and a spinning cake is formed. The spinning pot is displaced along its longitudinal central axis between an upper end position and a lower end position. An outlet opening of the yarn guide is located in the vicinity of the lower edge region of the spinning pot when it is in the upper end position. A yarn holder for receiving yarn from the spinning pot, and a substantially horizontal transport apparatus for moving the yarn holder to the spinning pot for rewinding the spinning cake onto the yarn holder is provided. The transport apparatus moves the yarn holder away from the spinning pot when it is in the upper end position.

  • Patent number: 5184786
    Abstract: A method and apparatus for controlling the yarn tension of yarn being cross-wound onto a bobbin on a textile winding machine. The amount of yarn on a supply package from which yarn is unwound is determined optoelectronically, gravimetrically or by measuring the yarn tension. The winding speed of the bobbin is adjusted in response to the determined yarn amount of the supply package so as to maintain the yarn tension substantially constant during unwinding. The winding speed of the bobbin can be controlled to follow a predetermined winding speed program which corresponds to the determined mass of the supply bobbin. To determine the yarn amount gravimetrically, the supply package is weighed by a balance device as it is conveyed thereover by a conveyor. The movement of the balance in response to the mass of the supply package can be electronically transmitted to a control device which prepositions a cam having a profile corresponding to the predetermined winding speed program.

  • Patent number: 4918911
    Abstract: A spinning machine has an electric motor for rotating a bobbin-supporting spindle to build a package of yarn thereon and a funnel for guiding yarn onto the spindle. The spindle is rotatingly driven by an electric motor and the electric motors of the spindle and the funnel are commonly connected to a frequency control means which is, in turn, connected to an electrical power supply means. The torque of the funnel electric motor is a function of a characteristic of the funnel in accordance with the relationship that the funnel is rotated by its electric motor at a lower rate relative to the contemporaneous rate of rotation of the spindle. The apparatus can include a switch assembly selectively movable between leads for selectively connecting the funnel electric motor to the frequency control apparatus to operate the motor or to the electrical power supply means to brake the motor.
