Definitions

  • the invention relates to a connection of the end regions of fiber associations in which the fiber associations are non-positively wrapped by fibers over a region of the length of the connection.
  • a fiber dressing is generally understood to be a bundle of fibers, a thread or twine, a cord or a rope or a similar elongated structure of combined fibers or threads, which can be both plant, animal and synthetic base materials .
  • the main field of application of the invention is the field of the textile industry in the broadest sense, without however being restricted.
  • connection of fiber associations generated by a link also has the disadvantage for many applications that the node produced necessarily has a considerably larger cross section than a single fiber association.
  • this can have an adverse effect and form a cause of thread breaks or other operational disturbances.
  • Various proposals have therefore already been made to solve the connection of fiber material in other ways than by a link.
  • a method for forming a thread splicing with a knotting device comprising an air nozzle is known, the special feature of which is that the two webs or threads, one end of which in a thread insertion opening of the air nozzle of the knotting device from one side and the other end is inserted into the opening from the other side, are assigned to one another and then at least one of the threads is loosened slightly before or at the same time as the air is blown onto the threads.
  • the textile threads to be connected are inserted into the swirl chamber in such a way that they wrap around both mouth edges of the swirl chamber, the subsequent swirling of the textile threads with looseness without tension in the swirl chamber, but held by the thread clamping devices, and the loosening of the thread tension is only so great is made that the false twist imposed during the swirling of the textile threads and the resulting shortening of the thread length brings the textile threads into contact with the mouth edges of the swirl chamber.
  • DE-A-1 962 477 discloses a device for splicing yarns with a drum rotatably mounted on a housing element, a yarn channel running through the axis of the drum for receiving overlapping ends of yarns to be spliced parallel to one another, with devices for turning the drum around the overlapping ends of the yarn to be spliced and devices carried by the drum for receiving a winding thread source, characterized by a thread channel in this drum with a discharge opening adjacent, but radially offset against the axis of this drum, whereby a high torque occurs during operation the winding thread is exerted, which runs through the thread channel when it is twisted around the yarn.
  • connection point becomes relatively stiff in relation to a normal fiber structure and can therefore lead to processing difficulties.
  • subsequent removal of the wrapping yarn requires an additional operation on the products made with such types of yarn. Difficulties can also arise in the procurement of suitable wrapping yarns for all possible fiber associations to be processed.
  • the present invention is therefore based on the object of connecting fiber bundles To create the, which avoids the disadvantages mentioned and in particular can be generated very quickly, for example in a matter of seconds, has both a high speed, a connection diameter which does not differ significantly from the diameter of the fiber structure and a high tensile strength, the connection also not having any significant the further processing of the connected fiber dressings should have an impediment or aggravating property.
  • the fibers used for looping are formed from the connection area of at least one of the fiber associations itself, from which they are not separated.
  • connection is thus based on the deliberate displacement of components of the fiber bandages to be connected, which makes it possible to achieve a connection diameter that does not significantly deviate from the diameter of the fiber band and a high level of suppleness while still ensuring tear resistance.
  • the fiber assemblies to be connected to one another are placed in at least approximately parallel, closely adjacent positions to one another, the special feature of the method being that at least part of the circumference of each of the fiber assemblies to be connected and the All of the fiber bandages are exerted by physical contact of the same with at least two deformation members that compress the fiber bandages in the opposite direction transversely to the length of the connecting region, both shear forces and tensile and / or compressive forces, in order to change the original cross sections and / or structure of the fiber bandages to be connected and on the other hand, at least partially detach individual fibers from at least one of the fiber associations to be prevented from their association and relocate them in such a way that they finally contain the fiber associations to be connected in at least part of the Wrapping the area of action of the deformation elements in a force-fitting manner and then connecting them through the loop. which fiber associations are brought out of the area of influence of the deformation elements.

It has also been shown that connections produced by the described method, if the parameters are optimally selected, already have a sufficient tensile strength at a length L of the connection 1 from approximately the size of the diameter D, for example in the range of the tensile strength of an individual fiber structure or even lies above.
  • connection is their very high flexibility and the fact that the diameter D of the connection can be chosen approximately equal to the original diameter of one of the fiber associations to be connected. Another advantage of the connection described can be seen in the fact that no foreign materials are required for the wrapping 4, so that, for example, there are no differences in the subsequent coloring. Finally, it should also be pointed out that the device 10 required for executing the connection is constructed much more simply, for example, compared to automatic knotting devices, and can therefore also be produced at lower costs. Due to the low energy consumption, it is also very easily possible to produce a movable or portable device, for example with a battery-operated electric motor drive.
