    Abstract: A method for operating an open-end rotor spinning machine having a plurality of workstations, usually a large number, each including a spinning device with a rotor housing, to which negative pressure can be applied, in which a spinning rotor (23) revolves at a high rotational speed, to produce a yarn, as well as a winding device to produce a cross-wound bobbin (18), wherein the connection of the workstations to a central negative pressure supply can be selectively switched off. The application of negative pressure to the rotor housing is limited to the spinning devices which are producing yarn as well as the spinning devices which are repiecing.

  • Patent number: 8006476
    Abstract: In a device on a textile machine, for cooling heat-emitting electrical components, for example electrical switching devices and/or switch cabinets, the heat-emitting components are cooled by an air stream. In order to provide a device that ensures the necessary cooling in a structurally simple way and is economical and low-maintenance, at least one partial air stream of the supply air to the machine is guidable towards the heat-emitting components and the supply air is able to absorb heat from the components and subsequently flow via outlet through components of the textile machine.

A centrifuge (6), a drawing frame (1), a piecing mechanism (2), and a traversing thread guide tube (4) are used. The centrifuge (6) rotates in a space (7) under reduced pressure (pu). Normal air pressure (pn) prevails inside the centrifuge (6) and spinning is carried out under normal air pressure (pn) inside the centrifuge. The reduced pressure (pu) is adjusted in such a way that, during rotation of the centrifuge (6), essentially only the bearing friction of the centrifuge still occurs but the air friction of the outer wall of the centrifuge (6, 35, 45, 53) against the housing (5') is largely suppressed.

    Abstract: The jacket enclosing a motor driven textile spindle of the type wherein the spindle is driven by a separate motor which is mounted on a common base with the spindle is modified to include air inlet and air exit openings. The motor is located in proximity to the spindle and is coupled to it by a toothed belt or the like. As the spindle is rotated by the motor air is drawn in through the inlet opening of the spindle and exits through the exit openings in the form of a strong stream of air which blows on and cools the motor. In this manner the spindle doubles as a fan for the motor and the necessity of providing a separate fan for the motor is avoided, resulting in savings in space and energy for driving a fan.

  • Patent number: 4693069
    Abstract: A heat-insulating jacket extends around each rotating can of a doubling machine. Half way up the height of the can envelope surface, an extraction line for extracting the air heated by friction as the can rotates extends into the interior between the jacket and the can. The end-face boundaries of the rotating can and/or top and bottom closure members of the jacket are such that the pressures of the air drawn into the jacket are at least substantially equal at the top and at the bottom.

  • Patent number: 4671054
    Abstract: A mechanism for pneumatically purging undesirable fiber fluff and dust from a spindle assembly of a two-for-one twister textile thread processing machine created during thread processing and particularly in the area of a rotating thread balloon and being characterized by utilizing air flow created by operation of the spindle assembly in processing thread without disturbing the rotating thread balloon is provided. The purging mechanism includes a housing jacket axially mounted on one end of a balloon limitor device and having a generally curved inner wall spaced from the axis of the spindle assembly rotor mechanism and the carrier mechanism a greater distance than the inner wall of the balloon limitor and a lateral opening on one side thereof, and a duct connected to the lateral opening and adapted to lead to a collecting container.

  • Patent number: 4628677
    Abstract: In a friction spinning process, a method is provided for preventing build up of dust and fly etc. inside a friction spinning machine (1) which method comprises the steps of introducing into the machine a flow of filtered air at a pressure just sufficient to substantially prevent the ingress of unfiltered air during spinning. The invention also provides apparatus for performing the method described, which apparatus comprises filter means (19), pressurizing means (20), ducting (22, 23) adapted to permit the outflow of clean pressurized air into the inside of the machine (1) adjacent the or each spinning head (3) at a pressure sufficient to substantially prevent the ingress of unfiltered air during spinning.
