A method and apparatus for marring the surface of a fiber optic substrate by feeding the substrate between a pair of rotating rollers. One of the rollers is coated with an abrasive. The second roller may be hard or have a deformable cover. Alternatively, one or both rollers may be serrated to produce a ripple pattern in the substrate. A hydraulic, pneumatic or other device is used for either manually and/or automatically adjusting the gap between the rollers. One or both rollers may also be heated to further enhance the marring action. A cam mechanism may also be used to adjust the pressure in the nip.

Méthode et appareil servant à rayer la surface d'un substrat de fibre optique tout en faisant avancer ce substrat entre une paire de rouleaux rotatifs. L'un de ces rouleaux est enduit d'un abrasif. L'autre peut être dur ou revêtu d'une enveloppe déformable. L'un de ces rouleaux ou les deux à la fois peuvent également être striés pour créer un motif ondulé dans le substrat. Un dispositif hydraulique, pneumatique ou autre sert à ajuster manuellement et/ou automatiquement l'écartement des rouleaux. L'un de ces rouleaux (ou les deux) peut être réchauffé pour améliorer le rayage. On peut également user d'un mécanisme à came pour ajuster la pression du resserrement.
