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.
Claims12
A method for marring a fiber optic substrate comprising;
- feeding the fiber optic substrate between a pair of rotating rollers that form a nip, said pair of rotating rollers comprising a first roller and a second roller wherein at least one roller has a roughened surface for marring the fiber optic substrate as it passes through the nip, and wherein at least one roller is adjustable to vary the pressure in the nip;
- and
- varying the pressure in the nip to obtain a predetermined marring pattern on the fiber optic substrate.
The method of marring a fiber optic substrate comprising;
- feeding the fiber optic substrate between a pair of rotating rollers that form a nip, said pair of rotating rollers comprising a first roller and a second roller;
- adjusting at least one of the rollers with respect to the other roller at least when the substrate passes through the nip to adjust the nip in order to vary the marring of the substrate to obtain variations in the amount of light escaping from the substrate along its length.
