Abstract: It is known that a plurality of optical fibres made from plastic or coated with a polymer material can be combined to form a bundle of optical fibres aligned in the same direction, at first temporarily and then permanently. The temporary fixing includes the step of establishing the relative mutual alignments of the individual optical fibres in the permanently fixed bundle. Known methods produce bundles with a non-homogeneous light distribution at the outlet and/or have insufficient tensile strength. The methods in question are complex, technically difficult to automate or entail long melt periods. According to the invention, fibre bundles with a particularly homogeneous light distribution at the outlet and capable of withstanding a tensile load of up to 70 N are produced by injection of a setting plastic melt around the temporarily fixed optical fibre bundle along a section of the bundle length for the final fixing of the individual fibres. Also disclosed are bundles of optical fibres made entirely of or merely coated with plastic.
