ABSTRACT:
The end faces of a plurality of parallel optical fibers are all located in one plane at right angles to the general direction of the fibers after simultaneous cutting by a tool unit comprising a sliding shoe which carries a cutting-tool support. During translational displacement of the shoe, the cutting edge of the tool scores each optical fiber in turn. A flat, parallel array of fibers is stretched tangentially to the top generator-line of a bearing cylinder and held in position between two clamping members on each side of the bearing line. At the level of the notch formed in the glass fiber by scoring, each optical fiber is split in transverse cross-section by applying an abrupt tensile stress or flexural deformation to the fiber.
