Method and device for stripping fibers of a fiber bundle

An Apparatus for stripping fibres of a fibre bundle, wherein each fibre has a core and a sheath, comprising:

• a cutting module including a base, a holding unit, a fibre rotating unit and a cutting unit;
• and
• a pre-weakening module including an immersion unit and a container including a chemical solvent,
• wherein the holding unit holds the fibre bundle on the base in such a way that the fibres are disposed next to each other and extend along a first direction, the cutting unit including a cutter that extends transverse to the first direction and that cuts into the sheaths of the fibres, the fibre rotating unit, when the cutter cuts into the sheaths, rotates all fibres simultaneously about their longitudinal axis on the base, such that the cutter produces a cut running in the circumferential direction in each sheath, and wherein the immersion unit immerses the fibre bundle, as far as the cuts in the fibres, in the solvent in the container for a predefined period of time, in order to pre-weaken the bond between the sheath and the core.
