Definitions

  • This invention relates to a texturizing machine of a type which comprises, within a head frame, a yarn path extending between a pay-off bobbin and a take-up bobbin, a plurality of feeders arranged along said path and interleaved to a first oven, a false twist spindle, and a second oven, as well as an air-blast interlocking device.
  • the first oven located upstream of the false twist spindle, serves the function of freeing the yarn of distortion as set in by prolonged storage in a wound state around the pay-off bobbin.
  • the second oven which locates downstream from the false twist spindle, is instead operative to relieve the yarn of the snap imparted to it by the false twist spindle.
  • the air blast is effective to ruffle the yarn, thus contributing toward an increase of the yarn bulk and assisting the false twist spindle in providing a desired yarn bulkiness.
  • the air-blast interlocking device has been positioned along the yarn path either between one feeder and the take-up bobbin, or between the outlet of the second oven and said one feeder, or alternatively and preferably, between one feeder and the inlet to the second oven, which will therefore be acting on yarn previously subjected to the air blast.
  • this invention provides a texturizing machine which is characterized in that it comprises two feeders set close together but sufficiently spaced apart to accommodate the air-blast interlocking device therebetween.
  • the texturizing machine 1 comprises a stationary head frame 2 which rests on the floor through feet collectively indicated at 3.
  • the head frame 2 which may have a length of some tens meters, comprises an elongate center body 4 and, arranged on a right-hand side of the latter, a right-hand side body 5, a lane 6 being left between the center body 4 and the right-hand side body 5.
  • the head frame 2 further comprises a left-hand side body, not shown, which is identical with the right-hand side body 5, since the texturizing machine 1 has a longitudinal plane of symmetry extending along the length of the center body 4 and whose trace is indicated at X-X.
  • the machine 1 comprises, arranged along its length, a plurality of texturizing stations, collectively indicated at 7, which are laid abreast at regular pitch distances along the head frame 2 in two arrays extending symmetrically about the symmetry plane having the trace X-X.
  • a yarn travel path which extends between a pay-off bobbin 9 and a take-up bobbin 10.
  • the pay-off bobbin 9 is received in a creel 11 carried on the side body 5, whereas the take-up bobbin 10 is accommodated in the center body 4 such as to bear on a powered roller 12.
  • this texturing machine includes a first oven 13 attached to the right-hand side body 5, a false twist spindle 14 mounted to the center body 4, and a second oven 15 attached to the center body 4.
  • each of said plural feeders comprises a powered roller 20 and a drive belt stretched between two pulleys 22 and 23.
  • the roller 20 and pulleys 22, 23 are arranged such that the belt 21 will have a working run 24 pressed against the roller 16 in contact therewith.
  • the feeder 16 is located downstream of the pay-off bobbin 9 and upstream of the first oven 13.
  • the feeders 17 and 18 locate between the false twist spindle 14 and the second oven 15, and are set close to each other as appropriate to define therebetween, along the yarn path 8, a yarn path section 25 having a predetermined length.
  • the texturizing machine 1 includes, located along the yarn path 8 and specifically the section 25 thereof, an air-blast interlocking device, known per se, which comprises a tubular sleeve 27 mounted to the center body 4 and being fed with air from an injector 28.
  • the length of the section 25 would be selected to have a limited but sufficient value to allow said air-blast interlocking device 26 to fit in the space between the feeder 17 and the feeder 18.
  • this is located downstream from the second oven 15 and upstream of the take-up bobbin 10.
  • the yarn is then entrained by the feeders 17 and 18, it being passed under a predetermined tension as required for interlocking through the blasted air interlocking device 26.
  • the yarn is then passed through the second oven 15, while being dragged along by the feeder 19 which applies a preferably gentle predetermined pull to it.
  • the yarn paths through two stations 7 abreast share a common interlocking device 26.
  • two yarns 30 and 31 from two adjacent stations 7 in the abreast arrangement can be coupled together along the respective sections 25 upstream of their common air-blast interlocking device 26.
  • the common interlocking device 26 may be set astride the two stations (see Figure 4), and possibly offset angularly (see Figure 5).
  • the yarn paths of two stations 7 abreast have in common two feeder devices 17 and 18 and one interlocking device 26.
  • two yarns 32 and 33 can be coupled together along their respective paths 8 ahead of the section 25 and upstream of the feeder 17 of one of them.
  • the interlocking device 26 being utilized may be either that of one station (see Figure 6) or set astride the stations (see Figure 7) and possibly offset angularly (see Figure 8).
  • a major advantage of the texturing machine according to the invention is that it affords unprecedented energy savings; by virtue of the yarn path section through which the interlocking device is operative being made short, the desired bulkiness can be achieved for a reduced expenditure of pressurized air.
  • Another advantage is that the interlocking can be made smoother and more uniform along the yarn; it has been found, in fact, that the resulting bulkiness does not tend to unravel itself.
  • the inventive texturing machine can provide satisfactory coupling of yarns from adjacent stations with each other.
