Definitions

  • This invention relates to methods and apparatus for handling yarns on yarn-storage yarnadvancing devices. More particularly, this invention relates to methods and apparatus for handling a plurality of yarns together on a yarnstorage yarn-advancing device whereby the yarns are advanced together in closely spaced helical turns of the plurality of the yarns along the yarnstorage yarn-advancing device and the yarns are separated irom each other as they are withdrawn from the device.
  • Yarns are advanced in helical turns on yarnstorage yarn-advancing devices which are well known in the art while the yarns are being merely stored, subjected to liquid treatment, or dried.
  • yarnstorage yarn-advancing devices which are well known in the art while the yarns are being merely stored, subjected to liquid treatment, or dried.
  • a plurality of yarns are advanced together in spaced helical turns along a yarn-storage yarn-advancing device with each of the turns comprising the yarns in proximity to one another, either associated together or spaced a slight distance apart, and the yarns are separated from each other as they are withdrawn from the device.
  • the plurality oi yarns are directed to a yam-storage yamadvancing device in spaced apart relation, and
  • the yarns are allowed to become in proximity to one another in side by side or superposed relation as the turns of the plurality of yarns are advanced along the device to the discharge position.
  • the position of one or more of the yarns being directed to the device is shifted laterally relative to one or more of the other yarns being directed to the device.
  • the distance a yarn is shitted is approximately the distance it is desired to have the diflerent yarns separated from -eiatch other as the yarns come of! the discharge end of the device. This distance may be varied depending on the size of the yarns and their condition as to wetness with treating liquid ii the yarns are wet.
  • the desired distance is that sufliclent to overcome any capillarity between the yarns as they are being discharged from the device if they are wet and sufllcient to permit each yarn to be separately engaged by a hook or the fingers of the operator so that each yarn may be separately directed to a take-up means or another yam-storage yarn-advancing device.
  • the yarn is shifted laterally a distance approximately equal to the pitch of the device to which the yarn is being directed, or if desired, the yarn is shifted laterally a distance that is approximately equal to a multiple of the pitch of the device to which the yarn is being directed. In other words, the yarn is shifted a distance that is approximately equal to a whole number times the pitch.
  • This shift in the position of a separate yarn being directed to the device causes a shift or displacement oi' this yarn relative to the other yarns on the device.
  • the portion of the yarn that had been shifted comes to the discharge location on the device, it is in a position spaced along the device from the position in which the preceding portion of the yarn was discharged. In this way the difierent yarns are spaced apart from each other at the discharge location on the device, and the yarns are separated from each other as they are discharged from the device.
  • the methods and apparatus of the present invention may be used in the storage, liquid treatment, and drying of a plurality of yarns together on a single yarn-storage yarn-advancing device or on a plurality of such devices in succession and are particularly adapted for use in the manufacture of artificial yarns by the viscose or other process.
  • the invention has for its principal object to provide methods and apparatus for handling a plurality of yarns together in closely spaced helical turns of the plurality of the yarns on a yarnstorage yam-advancing device whereby the yarns are separated from each other as they are removed from the device.
  • a further object of the invention is to provide improvements in methods and apparatus for spinning artificial filaments in which a plurality of yarns are separately formed and are advanced continuous spinning and processing machine for artificial filaments in which the invention is embodied.

  • Applicant's invention whereby diflerent yarns which are advanced together in closely spaced turns on a yam-storage yarn-advancing device may be separated as they are discharged from the device, may be practiced with the yam-storage yarn-advancing devices 1, III and I! as shown in advancing device I0 through one of the guide Y ways in the guide means II or after a number of the drawings and the method will be described with reference thereto.

  • the yarns may be directed to the device 1 with the yarn B in the groove 20 and the yarn A in the groove I9. The yarn B is then shifted laterally and is placed in the groove I8.
  • This shift in the position of a separat yam being directed to the device causes a shift or displacement of this yarn relative to the other yarns and forms a lap of th yarns for a turn or a portion thereof on the device.
  • the first portion of the yarn that had been shifted comes to be discharged from the device, it is in a position spaced along the device from the position from which the preceding portion had been discharged.
  • Th different yarns are spaced apart from each other at the discharge end of the device and therefore continue to be separated from each other as they are discharged from the device as shown in Figure 2;

  • the yams A and B are manually separated at the guide l9 and are directed to the yarn-storage yam-advancing device l2 as spaced apart relation through th spaced guide ways in the guide means i 3 as shown in Figure 4.
  • Figure 7 shows the positions of the turns of the different yarns when the yarns are directed to the device spaced from each other a distance that is equal to the pitch of the device.
  • the yarns A and B are directed onto the device in the positions AI and Bi respectively.
  • each of the yarns are advanced to the right as shown by the arrow a distance equal to the pitch.
