ABSTRACT:
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.
