Abstract: A lashing assembly lashes together two or more fiber optic telecommunications cables. The lashing assembly comprises at least a first and a second bobbin. As the cables are passed through the first bobbin, twine pays off from the first bobbin and wraps around the cables in a clockwise helix. As the cables are passed through the second bobbin, twine pays off from the second bobbin and wraps around the cables in a counterclockwise helix. In this way, the twine from the first and second bobbins lash the cables together as the cables are passed through the first and second bobbins.

Abstract: A precision method is defined for identifying defective sections of a spoolable material for removal. Defective sections are noted during manufacture and the spool containing the material is subsequently unwound to allow removal of the defective sections. The invention uses rotation data corresponding to the location on the spool where the fiber contains defects. A process controller records rotational positioning data from the take-up spool during manufacturing and uses the information to locate the defect when unwinding the spool. In addition, the pitch of winding the fiber onto the spool may be altered during manufacturing to indicate the beginning and end of a defective section. In this instance, the defective portion of the fiber can be determined during unwinding by monitoring the pitch width of the material. Finally, an algorithm for defining cut out bands adjacent to the defective sections aid in ensuring that no remaining defective fiber remains.

Abstract: A method and apparatus for monitoring run/stop conditions of a yarn, particularly in a knitting or warping machine utilizing a yarn feeler. The yarn feeler includes an electronic, yarn actuated transducer operating with variable gain amplification of run input signals which are further processed to final output signals representing the run/stop conditions. The amplification gain for the run input signal is automatically electronically controlled with a time delay and is adjusted towards a floating minimum which is just sufficient to derive stable final output signals. The, reaction time delay allows compensation for naturally occurring parametric fluctuations of the run input signal, while a sudden drop of the run input signal due to yarn breakage is processed to a final output stop signal.

Abstract: The object of the present invention is to allow the reliable identification of the quality level of the winding package based on the yarn quality such as the yarn winding tension or the twisting density when manufacturing a winding package. According to the draw texturing machine for winding while traversing the false-twist textured yarn Y unwound from the supply yarn package and forming a winding package 7 of taper end form, a tension sensor 20 for detecting the tension of the yarn Y to be processed into a winding package 7, and a quality level judging means 30 for judging the quality level of the winding package 7 based on the detected tension information, are provided.

Abstract: The present invention provides a system for determining the deployed length of a flexible tension element such as cable which is wrapped in a pack and fed through a funnel. The element may be sensed using different types of sensors such as optical, acoustical or magnetic sensors. A sensor is mounted in a funnel flush with the inside funnel surface. As wraps of the flexible tension element are deployed, or pulled off from the pack, individual wraps of the flexible tension element pass across the face of a detector as the flexible tension element is displaced in a generally circular pattern around the inside of the funnel. Signal processing circuitry produces a signal indicating the presence of the flexible tension element within a predetermined distance of the sensor.

Abstract: An apparatus, for measuring a yarn tension, capable of preventing a filament breakage or loop from being generated while eliminating the necessity of adjustment and keeping a desired precision of measurement. The apparatus is constructed by an unit 1 for an application of a vibration to a yarn being moved, an unit 2 for measuring an apparent transverse wave propagation velocity of the yarn, and a unit 3 for calculating a true transverse wave propagation velocity based on the yarn speed and the calculated apparent transverse wave propagation velocity of the yarn. A control of a winding of the yarn in accordance with a propagation velocity of the transverse wave is also disclosed.
