  • Patent number: 7055222
    Abstract: The invention relates to fastening means (in particular to so called clothing clips) for the fastening of clothing strips on flat rods, made of light metal or light metal alloys. Thereby the fastening means are laid-out in such a manner that, when the flat rods assume their operating temperature, these are not deformed.

  • Patent number: 6782685
    Abstract: An apparatus and method for producing a core spun yarn by means of a fluid delivery device is provided. The apparatus substantially comprises a fiber and thread guide means using a fiber guide conduit with a fiber guide surface for guiding fibers and a thread guide for guiding at least one continuous yarn into an inlet orifice of a yarn guide conduit and a fluid delivery device for producing a swirl flow about the inlet orifice of the yarn guide conduit so that the at least one continuous yarn can be spun over by the fibers. The thread guide is either a groove which is associated with the fiber guide surface, a bore disposed below the fiber guide surface, an individual tube-like element, or a tube-like element that is combined with a groove or a bore. The thread guide is introduced in a fiber and thread guide means, with the axis of the groove, the bore or the tube-like element being in alignment with the axis of the yarn guide conduit.

  • Patent number: 6611994
    Abstract: The present invention relates to the application of fiber length measurement in the blowroom or carding room of a spinning mill. A method and an apparatus in a textile processing machine are described in which before and/or after a working element of the textile processing machine the nep count and/or the fiber length (staple) is determined, with an open-loop/closed-loop control unit being provided which receives the values for the fiber length and/or the nep count as input and determines therefrom the optimized machine setting data and outputs the same to at least one actuator of a working element which influences the nep count and/or the staple of the textile processing machine.

  • Patent number: 4332059
    Abstract: A drive for the rolls defining a main drafting zone of drafting arrangements of long spinning machines, wherein in order to prevent drafting defects caused by distortion movement of the rolls, the latter are driven from one end by a first gear arrangement and from the other end are interconnected rigidly drivewise or slippage-free, respectively, during the standstill of the spinning machine via a second gear arrangement and via a freewheel clutch.
