Definitions

  • the present invention relates to the field of the textile industry, and more particularly to its sector concerned with the preparation of yarns of the types called "oncht” and “compensina”.
  • These types of yarn are formed by joining together, by an operation known in the technical terminology of the art as "doubling", a previously twisted thread and another thread which is untwisted or is twisted in the opposite direction, and by imparting to the set of two threads thus produced an additional twist, by means of a single or double twist spindle, in the direction opposite that of the thread, within the pair, which was previously twisted to the greater extent.
  • the said two threads, twisted and untwisted, or twisted in opposite directions, are first joined together and collected on a bobbin, and are then given an additional twist by means of the aforementioned single or double twist spindle.
  • the final, but not the least important, consideration is that, in order to enable the previously described doubling operation to be carried out between the threads, the twisted threads must in all cases be subjected, even if no dye is to be applied to them, to a steaming process which is necessary to distend the fibres and make the physical characteristics of the threads uniform throughout their length.
  • the inventor of the present invention has devised a process which eliminates the steaming stage, and at the same time reduces the space occupied by the equipment required for forming yarns of the onde or "compensina" type.
  • the winding members in other words the said reel 5 and the bobbin 6, are arranged coaxially and, in the example in question, are arranged one inside the other (but could also be positioned one outside the other in any other relative position in which they remain coaxial).
  • the reel 5 and the bobbin 6 are then mounted, again coaxially, on a double twist spindle 4 (of the type with a hollow rod 4c in the arrangement shown).
  • the twisted thread 2 is unwound from the reel 5 and drawn by traction by known methods towards the interior of the said double twist spindle 4, being joined in a parallel way to the other, untwisted, thread 3 which is unwound in the same way from the said coaxial bobbin 6 and follows the same path.
  • the two threads, arranged parallel to each other, pass through the double twist spindle 4, which imparts to them a twist which generally and preferably has a direction opposite that of the twist imparted previously to the said thread 2, which is the twisted thread in yarns of the onde type, or the more twisted thread in yarns of the "compensina" type.
