Definitions

  • the invention relates to a method for connecting ends of at least two threads, which are arranged in particular overlapping with Fadenend Schemeen and then connected together.
  • the individual threads of a layer are often very close together, making little room for handling the threads and creating the individual compounds is available. This situation is given, for example, in the connection of one end of a warp thread layer, as used in weaving machines, with the beginning of a new warp thread layer.
  • two thread ends are conventionally linked together by a node.
  • the knotting machines provided for machine node production require a relatively complicated and complicated mechanical construction.
  • the nodes are usually far thicker than the sum of the diameters of the two threads. This can be problematic in the further processing of the threads, for example when pulling through the connected threads by woven harness elements.
  • US Pat. No. 3,634,972 also discloses a splice connection and a method for carrying out the splice connection.
  • Disclosed is a method of winding a wrapping material about the intersecting or overlapping portion of two glass yarn ends, wherein the wrapping material is of a shrinkable thermo-sensitive type and remains on the yarn ends.
  • the wrapping material is for example a nylon or a polyester thread.
  • the wrapped area is then subjected to a heat treatment which causes shrinkage and fusion of the wrapping material with a synthetic polymer latex coating of the yarns.
  • the method has the disadvantage that it is relatively expensive, because separate process steps for the coating, the wrapping and the heat treatment are necessary.
  • the invention is therefore an object of the invention to provide a way for automatic connection of threads, especially thread ends, which mechanically strains the threads in the connection area as little as possible despite a high tensile load capacity.
  • the connection area should have the smallest possible thickness, so that a good further processibility of the connected threads is ensured.
  • the method according to the invention should also be possible to use as universally as possible, ie be suitable both for the connection of threads constructed as monofilaments, as multifilaments or as a fiber composite.
  • the connection of the threads should be generated within a time which allows an economical use of the method and a device for generating the connection.
  • the object is achieved according to a first aspect of the invention in a method of the type mentioned above in that a tool is guided around several times around the adjoining Fadenend Schemee, wherein the aid remains on the Fadenend Schemeen.
  • the object is also achieved by a device for connecting ends of at least two threads, which is provided with a holding device for holding with its end portions overlapping threads, a connecting device with which arranged in the holding device Fadenend Schemee are connected to each other, in which by the connection means a tool several times around Fadenend Schemee is feasible.
  • the aid in a gas or air flow to the threads.
  • the same or one or more other air streams should then be used to wrap the aid around the threads to be joined.
  • the air flow should impart to the tool an at least substantially predetermined direction of movement through which the tool moves around the threads. Preferably, this is done by means of one or more running around the thread ends or directed air vortices.
  • a device for this purpose can have one or more air vortex chambers, in which preferably at the same time the same Threads each a connection can be generated.
  • Such an embodiment is particularly cost-effective and, moreover, reliable against functional failures, above all because of the few, in particular the few, non-moving components.
  • a preferred embodiment of a device can provide a supply means with which the aid receives at least one component of movement during its supply movement, which extends transversely to the orientation of the threads to be connected.
  • a favorable embodiment of such a supply means may comprise a Fadeneinschussdüse with which the aid is supplied to the threads only using compressed air.
  • the aid also receives a movement component which is parallel to the orientation of the threads to be connected, which occupy them in the region of their connection point. This movement component can be imparted to the aid already during its delivery or only during an actual winding process, in which the aid is then guided around the threads.
  • an air flow is used, which moves helically around the threads due to the geometric shape of an air swirl chamber and an introduction direction of the air flow into the air swirl chamber.
  • the device may have at least two chambers in which flow preferably independent of each other air vortex.
  • the two chambers can be arranged directly next to one another and separated from one another by separating means. It has proven to be useful if the air vortices of the chambers are aligned in opposite directions. This can be achieved by appropriately oriented inlet channels for compressed air.
  • both the sense of rotation of the air vortex and their Longitudinal motion component, in a direction parallel to the threads be in opposite directions.
  • the invention is therefore based on the idea of arranging the end of the one thread and the beginning of another thread overlapping each other.
  • the two overlapping Fadenend Gebe here are preferably slightly stretched and aligned substantially in a straight line and parallel to each other.
  • a windable, longitudinally stretchable and preferably also slippery auxiliary device such as a yarn, is guided around several times.
  • the aid should not be an original component of the threads to be connected.
  • the aid can therefore also differ in terms of its material from the threads.
  • the auxiliary can be fed to the threads and subsequently guided around them.
  • the lead around the common circumference of the two Fadenend Gebe can be done in different ways.
  • These multiple turns result in a winding, wherein the winding can have turns with the same and opposite directions of rotation as well as a plurality of layers of turns arranged on one another.
  • the result of the inventive guiding around the auxiliary means can thus not only be understood to mean a structure consisting of a yarn with a certain number of helical turns.
  • the aid can be handled particularly easily while being carried around, if it is preferably in a fixed or in a fixed position a transition state to a liquid state of matter.
  • the yarn itself may be under at least low tensile stress during the production of the connection itself.
  • a simple handling of the aid during the generation of the compound and still a high load capacity can be advantageously achieved if the tensile load of the aid is increased after or before the end of the wrapping process and this tensile load remains permanently on the tool.
  • a suitable auxiliary may be a yarn which, under certain conditions, e.g. Heat or cold, shrinking or contracting.
  • An example of yarns having such properties are yarns having at least a portion of polyamide.
  • an elasticity of an aid can be used for connection generation.
  • the auxiliary means which are under relatively high tension, to be arranged around the two threads, but initially at a distance from them.
  • the aid can be arranged on spacers for this purpose. If you then remove the spacers, so the tool passes due to the tension and its elasticity on the threads and pushes them together. Since some of the tensile stress can be lost again, aids, for example an elastic yarn with a correspondingly high elastic elongation, should be arranged on the spacer.
  • the yarns with the names Lycra (trademark of DuPont, Geneva, Switzerland) or Dorlastan (trademark of Bayer AG, Leverkusen, Germany) can be used.
  • the tensile load of the tool can lead to a compression of the wrapped thread ends.
  • This pressure exerted on the thread ends is one of the operative relationships which are responsible for a tensile load capacity of the compound according to the invention.
  • An increase in the tensile load of the auxiliary can therefore be accompanied by an increase in the tensile strength of the connection.
  • the thread ends are compressed more strongly with higher tensile load of the aid, which in turn can lead to a smaller thickness of the finished connection.
  • it presses at greater tensile load of the aid this in the Fadenend Schemee, which in addition can also form a positive connection between the tool and the two Fadenend Schemeen arise.
  • a frictional connection between the two threads to be joined can also contribute to the strength of the connection.
  • an adhesion agent is additionally applied.
  • This adhesive has the primary purpose of reinforcing the connection between the aforesaid aid and the yarn end regions.
  • the adhesive is already contained in the aid itself.
  • a first and particularly preferred example of this are so-called combination melt-sticking yarns.
  • Such yarns have two components. While one component is a thin synthetic fiber thread, the other component may be a hot melt adhesive that develops its adhesive properties when heated.
  • Particularly preferred are combination melt adhesive tapes based on polyamide. With these yarns, not only is the amount of glue melting when heated, to connect with the threads afterwards.
  • the polyamide component also contracts and hereby generates a tension in the yarn and a compressive force in the threads.
  • the contracting produces a non-positive and, on the other hand, an adhesion and / or an integral connection by the adhesive.
  • the at least one heating process can be advantageously used in several ways. Also, such an adhesive bond is permanently zugbelastbar and thus increases the originating from the wrapping tensile strength of the connection.
  • Another example of creating an adhesive bond may provide that the tooling be coated with adhesive during delivery to the yarn ends. During or after the wrapping of the thread ends with the aid can then develop the adhesive by drying or curing its adhesion.
  • Fig. 1 one end of a partially shown warp thread layer 1 is shown in a highly schematic manner, as used in weaving machines.
  • the warp threads 2 are clamped in a frame 3.
  • a thread end 4 of a new warp thread layer 5 is to be added to the ends of the threads 2 of the warp thread layer end.

  • the yarn offered by the company Ems-Chemie AG, Domat / Ems, Switzerland, under the name GRILON® C-85 (with a yarn size of 2000 dtex) is used as the combination-melt adhesive yarn.
  • the combination-melt adhesive 8 is used for connecting in each case one thread 2 of the thread layer 1 with a thread 4 of the new thread layer 5 (not shown in FIG. 2).
  • the two threads are arranged for this purpose in the air vortex device 6 and wrapped there with the yarn 8, which will be explained in more detail below.

  • Both compressed air vortices move due to a pressure gradient approximately helically from the partitions in the direction of the respective open side of the two chambers 23, 24 out. Since the two holes 55, 56 open into their respective chamber on different sides with respect to a longitudinal direction of the two chambers 23, 24, the two compressed air vortices have opposite directions of rotation.
  • two mutually aligned grooves 25, 26 are introduced in the wall 20 at an angle of, for example, about 0 ° -15 ° with respect to the planar dividing wall 20 (FIG. 4).
