  • SHEET 8 BF 6 APPARATUS FOR TEXTURING R DRAWKNG ANll) TEXTURHNG SYNTHETIC YARNS This invention relates to apparatus for producing textured synthetic continuous-filament thermoplastic yarn by the well-known false twist process.
  • machines are known in which drawn yarn is textured as above described, but before being wound up is heat set in a partially relaxed condition and the heat set yarn is then wound up for further use.
  • false twist crimping machines should be provided with means for drawing yarn, either immediately before or during the texturing process effected by heating and false twist crimping, but in general these processes are more often carried out on machines adapted only for a single process, and in order to achieve high production rates these machines are arranged as a large number of adjacent stations in one or more rows, so that in constructing a machine there is assembled together all the parts needed for a particular process, especially the driving mechanism where a machine comprises two hundred or more stations.
  • the draw mechanisms of all stations of one row are connected to a common drive, and in a false-twist crimping machine the drives of the false-twist mechanisms are coupled to a common drive, as also are the yarn forwarding and take-up mechanisms.
  • the large masses of the drive transmission members do not permit high working speeds to be reached, the maximum being about 200 metres per minute.
  • the object of the invention is to provide apparatus for the production of textured yarn, or drawn and tex' tured yarn, which besides providing for processes such as drawing, texturing and setting, provides increased production rates and improved uniformity of yarn quality.
  • apparatus for texturing synthetic continuous-filament thermoplastic yarn is in the form of a machine unit comprising an elongate narrow linear support member providing a spline 'on which is mounted at least one yarn forwarding mechanism, yarn heating means, yarn texturing means and drive transmission means co-extensive with the spline, the yarn forwarding mechanism being located in the region of one end of the spline and being drivably connected with the drive transmission means, and a coupling element adapted for connection with a driving motor being located in the region of the other end of the spline and being drivably connected with the drive transmission means.
  • An auxiliary support member may be provided, which is releasably secured to that end of the spline where the yarn forwarding mechanism is located so as to form an extension of the spline, another yarn forwarding mechanism being mounted on the spline extension and being drivably connected with the drive transmission means, the two yarn forwarding mechanisms together providing a yarn drawing system.
  • a machine for simultaneously texturing multiple synthetic thermoplastic yarns comprises a framework providing a mounting for multiple removable individual machine units each comprising an elongate narrow linear support member providing a spline on which is mounted at least one yarn forwarding mechanism, yarn heating means, yarn texturing means and drive transmission means coextensive with the spline, the yarn forwarding mechanism being located in the region of one end of the spline and being drivably connected with the drive transmission means, and a coupling element being located in the region of the other end of the spline, and being drivably connected with the drive transmission means and also releasably drivably connected with an individual driving motor mounted on the framework adjacent said other end of the spline.
  • An auxiliary support member may be provided, which is releasably .secured to that end of the spline where the yarn forwarding mechanism is located so as to form an extension of the spline, another yarn forwarding mechanism being mounted on-the spline extension and being releasably drivably connected with the drive transmisson means, the two yarn forwarding mechanisms together provididng a yarn drawing system.
  • the machine units are mounted on the framework arranged in a horizontally extending row lying in a common upright plane, the splines of the machine units being parallel one with another and being inclined to the horizontal at an angle of about 10 to 60, so that the splines in the row overlap one another in their common upright plane.
  • the framework may also carry, for each machine unit, a setting apparatus for the textured yarn which comprises second heating means through which the textured yarn is passed for modifying its final elasticity.
  • the textured yarn is overfed through the setting apparatus with a predetermined degree of overfeed to be heat set in a partially relaxed condition as yarn having a relatively high final elasticity or a relatively slight final elasticity, according to the degree of overfeed of 5 the yarn through the heater of the setting apparatus.
  • the setting apparatus may be disposed in an upright disposition, or it may be disposed in an inclined disposition and is oppositely inclined relative to its associated machine unit, and the individual motor which drives a machine unit may also drive yarn forwarding mechanisms of the setting apparatus, as well as a windup assembly for the textured or the textured and heat set yarn.
  • the invention provides a basic machine unit which in itself is a texturing apparatus, while the drawing apparatus and the setting apparatus are optional extras which can be added to the basic unit at will when it is mounted on a suitable framework, with the drawing apparatus,the basic machine unit, the setting apparatus and the wind-up assembly forming a functionally homogenous production unit, the drives for the rotating parts of which are taken from an individual drive motor supplying only this one production unit.
  • Production units can be arranged in desired number in rows on a framework, without the production units being in functional connection with each other through a drive transmission or the like, which in known machines needed the provision of a so-called machine head.
  • the question of space is important, and the invention provides that a producer or user of textured yarn can acquire exactly the number of production units he requires and arrange them independently in rows on a suitable framework.
  • the noise level of the individual production units is low, as also is the noise level ofa multi-unit machine in comparison with conventional multi-staition machines, so that sound-damping floor and wall coverings are unnecessary, as also are ear muffs for operators whose performance characteristics show improvement. Living quarters in the neighbourhood of a factory are not disturbed because of the low noise level, despite increased production rates achieved by the production units.
  • a machine comprising a framework on which production units are mounted can be used for several processes.
  • yarn from draw-cops can be textured and wound up into bobbins or packages.
  • both drawn and textured yarn can be processed from spinning bobbins of undrawn yarn, and by adding the setting apparatus either textured and set yarn, or drawn, textured and set yarn can be processed from draw-cops or spinning bobbins respectively, so that with a relatively small capital cost good process adaptability is obtained.
  • the basic machine unit which includes the spline and its optional extension, has the drawing system, yarn infeed rollers, the texturing heater and the yarn texturing means arranged along a straight line, which provides for easy threading-up and for easy exchange of individual components or the whole machine unit, and also achieves better quality of the textured yarn especially as regards dye affinity and uniformity of dyeing.
  • the dispostion of machine units on a framework at an angle of inclination of 10 to to the horizontal leads to a saving in machine height, especially when long texturing heaters are employed.
  • Toothed wheels and toothed belts can be used with advantage to provide non-slip drive from the individual driving motor to the drive transmission means carried by the spline, and to the yarn texturing means, the yarn forwarding mechanisms, 'and the wind-up assembly.
  • the basic machine units, and the production units of which they form part, can be arranged each to process one yarn, or to process two yarns simultaneously.
  • FIG. 1. is a schematic diagram showing a production unit with a vertically disposed setting apparatus.
  • FIG. 2. corresponds with FIG. 1., but shows an inclined disposition of the setting apparatus.
