  • Below each of these enumerated parts on each roller are a plurality of troughs 34 for collecting surplus liquid which is led away through drain tubes 41 and pipes 42, as illustrated in Figure 2, for recovery or recirculation.
  • a hood or enclosure 35 may advantageously surround the roller part 18a and the roller 19 which form the lowermost thread-advancing, thread-storage device in the series upon which the thread may finally be dried.
  • the roller 19 advantageously has a hollow center for interiorly admitting steam or other heating medium such as hot air by means of concentric pipes 36 and 37. The roller is thereby heated in order to dry the thread, although other drying means for the thread may also be employed, if desired. If desired, one or more of the other rollers also may advantageously be internally or otherwise heated to facilitate applications of hot liquids and the like for treatment of the thread.
  • Beneath the last roller 19 is an integrated cap twister apparatus 39 which may advantageously be employed to collect the finished thread on bobbins While simultaneously imparting a nominal twist thereto.
  • Each roller has its axis canted askew at an angle to the axes of all the other rollers.
  • the axis of roller 15 is in the plane of the paper
  • the axis of roller 14 would be canted slightly in an angle behind the plane of the paper and the axes of rollers 13, 12 and 11 would have progressively increasing degrees of cant in the same direction.
  • the angle at which the axis of any roller is canted to the axis of an adjacent roller is about constant in order that the thread traveling over any thread-advancing, thread-storage device has about the same pitch or degree of helical advance. However, this may be varied to meet desired operating conditions.
  • the axes of the rollers 16, 17, 18 and 19 would be progressively increasingly canted in the opposite direction.
  • the end of the roller 11 and roller part form a single thread-advancing, threadstorage device.
  • the roller parts 121; and 13a form another, and so on through the entire series of rollers as shown in the drawing.
  • the axes of all the rollers in the same series are generally offset in a parallel relationship although, if it is desired to stretch or relax the yarn at various points on one or more of the thread-advancing, thread-storage devices, one or more of the rolls may be offset with its axis, or their axes, inclined at a suitable offset angle to the axes of the others for this purpose.
  • each roller may all conveniently be driven, a shown, from a suitable shaft bevel gearing. However, if it is desired-or found necessary, each roller may be driven separately, or, if preferred, through a common shaft having one or more universal joints.
  • a plurality of spinning positions which are continuously forming and supplying a plurality of ends of thread to a plurality ofadjacent series of rollers may be placed side by side in a bank to form a spinning machine which is adapted to simultaneously continuously process the plurality of ends of thread.
  • the apparatus may be incorporated in a two-sided machine having two banks of rollers placed in back to back relationship.
  • Figure 2 shows, in addition, a supply pipe Him the treating liquid which is fed therefrom to the liquid jets 33 to be applied to the yarn while it is being advanced in helical'form.

  • the thread 43 is formed into a helix on the threadadvancing, thread-storage device formed by roller 11 and co-extensive roller part 12a, and it is helically advanced over the uppermost pair of rollers. While in the form of a helix, the thread is treated with a treating agent which advantageously may be a liquid supplied through the liquid tube or jet 33.
  • the circumferential ridge or flange 31, or other desired liquid separating device such as a polyethylene band on the rollers, prevents surplus or excess treating liquid from passing along the roller to part 12b which forms part of the next thread-advancing, thread-storage device. Excess liquid is conveniently collected by a trough 34 positioned under the lower roller of each device.
  • a trough 34 positioned under the lower roller of each device.
  • roller part 18b and the roller 19 advantageously form a drying device which, if desired, may be contained in an enclosure 35. It may be found advantageous in some instances for these roller parts to be tapered to allow for shrinkage of the thread during drying. Steam or other suitable heating media circulated through the interior of the roller 19, which may be hollow for the purpose, by means of pipes 36 and 37 heats the roller 19 to dry the thread. The dried and finished thread, in a commercially acceptable condition, is then collected on the integrated cap twister apparatus 30, or on other take-up means such as a ring twister or a headless package forming collecting device.
