Definitions

  • This invention concerns a new kind of splice for yarns, whether they be textile yarns or not.
  • Splices made between textile yarns by fisher- mans's knots, weaver's knots or other kinds of knots are known. Splices between yarns are also known which are made with adhesives or with ties by winding the yarn or an outer tape.
  • Splices are also known which are made by intertwining and entangling the fibres of two yarns by blowing air or by means of electrostatic fields.
  • GB-2 066 315 discloses a device in which two yarns are spliced with a jet of air in a turbulence chamber.
  • the splice which can be obtained in this manner is irregular and includes zones having fibres which are not intermingled and which therefore protrude and form tufts.
  • the known splices entail drawbacks as regards their dynamometric properties and the ability to employ the spliced yarn in usage means downstream and also as regards the general characteristics of the joint.
  • Splices are also known which are made by untwisting the individual yarns, uniting them and retwisting together the tracts of the yarns to be spliced.
  • the feature of said joints is the coupling of two yarns by twisting them together after having brought them beforehand to the condition of almost parallel fibres before coupling them.
  • EP-A-39 609 (in the name of CSIRO) with priority AU3407/80 is known and discloses a device and method to splice two twisted yarns by untwisting portions of each yarn, tearing such portions from the yarn so as to form two tail ends, coupling the tail ends and re-twisting the same so as to form a splice, the yarn being clamped at gripping points spaced apart to define a specific segment of yarn to be untwisted, such specific untwisted segment remaining clamped between such distanced gripping points even after format i on of such tail ends, and at least part of such tail ends cooperating with at least two of such distanced gripping points.
  • GB 661 697 discloses a procedure to form a splice which is generic in itself and which can be performed by hand.
  • the known splices made with a jet or jets of air have their fibres bunched together and matted.
  • the spliced tract is stiffened thereby with a resulting loss of elasticity and even with considerable problems for the usage means downstream, particularly as regards dyeing work and warping operations besides other processes thereafter.
  • Our present invention proposes a splice for yarns, whether textile yarns or not, which not only has outstanding aesthetic features but also possesses important mechanical, technologic-logical and elastic properties and a long life.
  • the invention also proposes joints which are not only homogeneous but are also able to meet the requirements of various usage means thereafter.
  • said splices can be made individually suitable for the particular type of usage means by comprising intermediate and transition lengthwise sections of a type and form selected as desired.
  • the splice can include tail ends obtained by tearing or extraction or cutting, so that the tail ends themselves can be sheared or chopped, or be reduced or progressive.
  • the splice also comprises component yarns which tend to shrink lengthwise so that a centripetal reciprocal thrust of one yarn in respect of the other yarn takes place.
  • the various kinds of joint may have a joint diameter which varies between 0.8 and 1.8 times the diameter of the single yarn.
  • the joint can also have coils with a winding inclination of the coupled yarns of a desired type, for said inclination may be constant, variable or mixed, as desired and depending on the properties required.
  • the progression of the slope of the winding spirals may also begin at the middle of the joint and move towards the ends thereof.
  • a splice made in this way is, in itself, so stable that the tail ends or part thereof can be left substantially free.
  • the remaining tail ends are wound advantageously on the single connected yarns.
  • At least part of the joint may comprise a mutual penetration of the fibres.
  • the invention is therefore embodied in a splice for yarns, whether textile or otherwise, which is obtained by coupling tracts of single yarns by means of mechanically winding after having mechanically untwisted beforehand said tracts of single yarns (as is for example known from EP-A-39 609), and is characterized by comprising, at least in one tract of the splice, a number of twists of the coupled yarn which is greater than the number of twists included in the single yarns in the same tract, and is also characterised by having a reciprocal centripetal thrust as between the two yarns owing to an induced lengthwise shrinkage.
  • a splice 22 as in Fig. 5 with the tail ends 120 and/or 121 free (cut or torn, as in the example shown, or opened out) is stable enough and can be employed without any worries for given operations thereafter.
  • Said winding of the tails 120 and 121 is performed with the same device as that which arranges to make the splice 22, or with other suitable means.
  • the end points 124 of the fly fibres 24 can be anchored in and with other fibres, thereby creating better anchorage and intertwining of the individual yarns 20 - 21 both as between the two individual yarns and also as between one coil and another of the same yarn by passing the fibres over the intermediate coil of the other yarn.
  • This anchorage is further improved by a preferential orientation given to the fly fibres 24 themselves.
  • Said orientation is advantageously, but not necessarily, directed towards the end 23 of the splice 22 from the middle of the splice.
  • the tail ends 120 - 121 are advantageously wound tightly onto the other single yarn, 21 and 20 respectively, so that the last coils wound become protected by the protrusion of the face 25 of the single yarn onto which they are wound.
  • Fig. 4 shows this condition for instructional purposes, together with the bond created by the fly fibres 24.
  • Figs. 1. 2, 7 and 8 show some types of splices.
  • the splice of Fig. 1 is made without any thickening and compressive action; moreover, the tail ends 120 - 121 are pulled open, that is, progressive, and their end zone is wound progressively on the anchored yarn 21 - 20.
  • the joint 22 consists essentially of three zones, respectively a middle zone 26 with an almost constant development of the coils, a transition zone 27 wherein the coils change their slope progressively while the diameter of the joint is progressively lessened, and a zone 23 for the binding of the tails wherein the slope of the coils varies more quickly than in the zone 26.
  • This kind of splice may have in the zone 26 a maximum diameter varying between 1.25 and 1.8 times the diameter of the single yarn; in the zone 23 instead the maximum diameter may vary between 0.8 and 1.10 times the diameter of the single yarn.
  • Figs. 2 show a compressive and thickening effect produced during their formation.
  • This kind of joint may have a maximum diameter about 1.05 to 1.25 times the diameter of the single yarn in zone 26, whereas in zone 23 the diameter will be between 0.8 and 1.25 times the diameter of the single yarn.
  • Fig. 2b shows the case wherein the tail ends are about as long as the splice itself (as an example we have assumed the case of fibres spread out evenly in the tail ends).
  • the joint 22 still has a zone 27 for the splicing of the tail ends, but zone 26 is substantially lacking, whereas the transition zone 27 in practice covers the zone 23 as well.
  • Such a type of splice has a diameter between 0.8 and 1.25 times the average diameter of the single yarn, and said diameter may vary substantially within said limits along the axis of the joint.
  • splices which may be a combination of the joint of Fig. 2a and the joint of Fig. 2b, or a combination of said two joints and the joint of Fig. 1.
  • tails 120 - 121 are shown but bear no relation to specific cases and are merely illustrative.
  • the coils are oriented more at right angles, to the axis of the splice near the middle of the splice and then change progressively until they reach the edge of the splice with an accentuated slope.
