Definitions

  • My present invention relates to a process and an apparatus for twisting threads, generally as disclosed in my prior US. Patents Nos. 2,972,856 and 3,164,950, wherein a. plurality of threads are twined together in a first rtwisting stage including a ring spindle, the yarn constituted by these threads being wound on a bobbin core with a relatively low rate of twist whereupon the resulting bobbin is mounted on a high-speed second-stage spindle for uptwisting at a relatively high rate.
  • the rapid rotation of the yarn about the bobbin axis during uptwisting tends to cause ballooning which involves the risk of entanglement between threads from adjoining bobbins.
  • This risk is minimized by enclosing the second-stage bobbin support within a coaxial sleeve or bell which, advantageously, rotates with the bobbin while spacedly surrounding same, the yarn being withdrawn upwardly through an axial opening at the top of the sleeve.
  • the general object of my present invention is to provide an improved process and apparatus which Patented Aug. 5, 1969 ice affords the advantages of wet second-stage uptwisting while eliminating the aforestated drawbacks.
  • This object is realized, pursuant to the present improvement, by a wetting of the yarn-forming threads during the first twisting stage, i.e., during the building of the bobbin on a ring spindle or the like, the degree of wetting being sutficient to bring the wet and therefore relatively heavy yarn through centrifugal action into contact with the inner sleeve surface and to cause the formation of a liquid film on that surface, with resulting adhesion of the yarn to the sleeve in the manner envisaged in my German patent but without any need for maintenance of a pool of Water in the sleeve itself.
  • the process according to my invention operates even if the sleeve is not rigid with the spindle but is held stationary.
  • the threads may be wetted by a liquid other than water, including various oil or liquid parafiin; also, brighteners, bleaches, colorants and other adjuvants soluble in the medium may be dissolved therein to treat the filaments.
  • a liquid other than water including various oil or liquid parafiin; also, brighteners, bleaches, colorants and other adjuvants soluble in the medium may be dissolved therein to treat the filaments.
  • the amount of moisture in terms of the dry weight of the threads should be ranging between about 10% and 200%, preferably between substantially 15% and 50%. Since the threads pass at relatively high linear speed through the first twisting stage, several immersions may be needed in order to provide the necessary degree of moisture saturation.
  • the wet yarn emerging from the sleeve of the uptwisting stage will readily give up some of its moisture to the surrounding atmosphere so as not to be excessively damp upon being rewound on a final reel or spool.
  • FIG. 1 is a diagrammatic view of a first twisting stage of a system for performing my improved twisting process
  • FIG. 2 is a view of an axial section of a second twisting stage forming part of the same system.
  • the twisting stage shown in FIG. 1 comprises a pair of spools 1, 2 delivering threads or filament 1', 2 to a deflecting roller 5 from which they are jointly led through an eye 6 to a transport mechanism here shown as a pair of parallel rollers 7, 8 of different diameters.
  • the gathered filaments pass one or more times around the two rollers which are driven, by means not shown, in the direction illustrated by the arows.
  • the resulting yarn 10 is given a slight preliminary twist by being wound in a bobbin 15 on a core 15 removably seated on a vertical spindle 22 which is journaled in a stationary bracket 24 and is rotated by a belt 13 at a predetermined speed with reference to the feed rollers 7 and 8.
  • a traveler ring 14 revolves about the spindle axis on an annular track 11 which i mounted on a frame 12 adapted to move vertically in a manner known per se.
  • I provide a plurality of vessels 28a, 28b containing water or some other suitable liquid having the necessary wetting characteristics.
  • the yarn 10 is held down by idler rollers 29a, 29b partly immersed in the bath.
  • the yarn Upon emerging from the second bath 28b, the yarn is permeated by liquid which, if aqueous, should range between preferably 15% and 50% of the dry Weight of the yarn, the maximum range being 10% to 200%.
  • FIG. 2 shows the bobbin 15 mounted on a spindle 16 which is rigid with a surrounding sleeve 16, the latter being open at the top.
  • the wet yarn 10 passes upwardly from sleeve 16 via eyes 18 and 19 onto a take-up reel 20 which is frictionally driven by a roller 21 maintained in contact therewith by a spring 27 anchored to a supporting arm 26.
  • Sleeve 16, spindle 16' and bob-bin 15 are rotated at high speed about a vertical axis A by drive means including a belt 23, the spindle being journaled in a bracket 25.
  • drive means including a belt 23, the spindle being journaled in a bracket 25.
  • yarn wets the inner surface of sleeve 16 against which it is thrown by centrifugal force.
  • the yarn adheres to the sleeve up to a certain level at which it is drawn off into the eye 18, with little if any ballooning.
  • EXAMPLE I Dry cotton thread is twisted in the stage of FIG. 1 and, with the use of a single wetting station 28a or 28b, is impregnated with water in a portion of 11.75% of the weight of the dry thread. In the stage of FIG. 2, this moisture content is reduced to 1.9%.
  • a plant comprising a first twisting stage for twining a plurality of threads to form a yarn
  • said first stage including a ring spindle adapted to receive a bobbin core onto which said yarn is wound and a second twisting stage in which the yarn is drawn upwardly off said bobbin while the latter rotates about a substantially vertical axis
  • said second stage including a rotatable bobbin support and a yarn-guiding sleeve coaxially surrounding said support, the combination therewith of wetting means at said first stage for moistening said threads to a sufiicient extent to form a liquid film on the inner peripheral surface on said sleeve whereby said yarn adheres to said surface while being drawn otf said bobbin.
  • said Wetting means comprises a plurality of wetting stations positioned for sequential traverse by said threads.
