It is known from practice to insert an intermediate layer between the crimper and the cutter actuator, i.e. a disk-shaped molded part, the only function of which is to keep the crimper and the cutter actuator spatially spaced apart.
  • the intermediate layer does not participate in the fastening of the crimp sleeve on the conductor of the cable nor in the separation of the crimp sleeve from the carrier tape, since the intermediate layer maintains a distance from the cable and from the conductor of the cable at the reversal point.

  • Such a reduction in the diameter of the dielectric may be acceptable as long as the conduction properties of the conductor are not compromised; In some cases, a reduction in the diameter of the dielectric of the conductor may also be desirable. It should be noted in this case that in a method for crimping a crimp sleeve onto a conductor of a cable, reducing the diameter of the dielectric of the cable is carried out while the crimper is moving relative to the anvil, i.e. during the deformation of at least a section of the crimp sleeve by the Moving the crimper relative to the anvil such that the deformed portion of the crimp sleeve is secured to the conductor of the cable.
  • reducing the diameter of the dielectric is integrated into the clocked sequence of the crimping process and does not require any upstream or downstream process step. It should also be noted that reducing the diameter of the dielectric of the conductor does not require any material removal from the dielectric or any heat input into the dielectric, since reducing the diameter is carried out at ambient temperature, namely at the clock frequency at which the crimper and the anvil operate during the crimping process, i.e. when attaching the crimp sleeve to the conductor of the cable.

Due to the leading pretension of the holding layer 8 relative to the cutter actuator 5 by the at least one tension spring 11, the cable is first fixed in the area of the exposed dielectric during operation and the cutter 4 is actuated at a different time by the cutter actuator 5.
