  • Patent number: 4365765
    Abstract: The invention deals with problems arising in lubrication of the helical cam grooves of cam drums used in thread traversing mechanisms of winding machines. The drum is provided with an internal space acting as a lubricant reservoir. A passage extends between the space and the groove so that centrifugal force urges lubricant outwardly along the passage from the space towards the groove. Flow along the passage is controlled by a porous sintered metal body which permits a desired degree of a given lubricant to pass along the passage at a given rotational speed.

  • Patent number: 4365468
    Abstract: The false twist machine has a texturing part arranged below heat treatment zones in which three supply devices and a false twist device are superimposed and staggered from the back to the front in such a manner that in threading in of the thread into these devices turning about and overhead working processes of the operator are avoided. The thread paths formed by the threading in are placed one in front of the other in the sequence of the threading in process. A bobbin creel is movable to the texturing part and is equipped with a thread transfer device which transfers the threads coming from the individual creel bobbins into the vicinity of the first supply device. The winding device is arranged opposite the texturing part at a distance forming an operating alley and gives off the full bobbins to the outerside of the winding device opposite the operating alley. The empty bobbins can be moved from the machine end into a readiness reserve position.

  • Patent number: 4358065
    Abstract: The invention concerns an apparatus for producing thread or yarn reserve windings on a rotating bobbin tube (2), with a lever (5) for transferring the thread to the thread catching zone at the face side of the bobbin tube, with a thread guide curve (17) for guiding the thread while the thread reserve windings are formed, and with a thread stop (15) for temporarily holding the thread on the thread guide curve (17) for producing the thread reserve windings.
