Longitudinal member, especially a polymer optical fibre, is separated by cutting using a separating tool with a cutting edge that also smoothes the separation surface

摘要

A process for separating a longitudinal member, especially a polymer optical fibre, comprises cutting the member (2) using a separating tool (1) cutting edge, and then smoothing the separation surface. Separating and smoothing are carried out in a single step using the tool. A tool surface with abrasive granules (3) is used to smooth cut. The separation tool surface is smooth and is heated during separation. Heating is carried out using a radiation source (5), eg a light source.
