  • the width W of the area of action 14 changes. If the swivel members 52a and 53 are actuated, for example, by a lever mechanism 54, the device 10a with a large width W can be in the range of fixed fiber associations to be connected 2 and 3 are brought without the fiber assemblies 2 and 3 already coming into contact with the deformation processes 11 and 12.
  • the deformation members 11 and 12 can be brought together by actuating the lever mechanism 54, whereby the deformation of the fiber assemblies begins and a connection 1 is established.
  • opening the action area 14 can be achieved by actuating the lever mechanism 54 again, and the device 10a can be pulled away, so that the interconnected fiber associations 2 and 3 with their connection 1 are freely accessible.
  • An embodiment of the device 10 according to variant 10a is particularly suitable for use in an automatic workflow.
  • V e rfah- Ren and connections 1 can be generated with the facilities described, which fully meet all practical requirements. It should be noted here that such a connection is created in about one second and the entire working cycle, ie insertion of the fiber associations, formation of the connection and removal of the connected fiber associations can be carried out within a few seconds. It has further been shown that connections produced by the described method, if the parameters are optimally selected, already have sufficient tear resistance at a length L of the connection 1 from approximately the size of the diameter D. which is in the range of the tensile strength of a single fiber structure or even higher.
  • 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 the implementation of the connection is much simpler compared to automatic knotting devices and there can also be manufactured at a lower cost. 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.
  • the device also has the advantage of having a self-cleaning effect in that contamination of the device is practically avoided by an air flow generated by it or its moving parts.
