ABSTRACT:
An optical fiber severing device comprising a support for retaining a plurality of optical glass fibers in spaced relationship, scoring device for inflicting a flaw on the glass surface of each of the optical fibers providing each of the fibers with first and second portions on opposite sides of its flaw, a pressure mechanism for slidably engaging each of the fibers and applying pressure to a contacted area of each of the fibers, and a motive mechanism for applying respective tension forces between the first portions of the fiber and the pressure means and concurrently moving each of the fibers with respect to the pressure mechanism so that the contacted areas pass over the flaws as they move along the surface of the fibers from the first portions to the second portions. The method of the invention for concurrently severing a plurality of optical fibers comprises the steps of (a) inflicting a flaw on the glass surface of each of a plurality of optical glass fibers to be severed, (b) contacting an area about each of the fibers for applying pressure respectively to each of the fibers, and (c) applying pressure for producing respective frictional forces sufficient for severing the fibers and concurrently moving each of the contacted areas to which pressure is applied along their respective fibers and over their flaws to sever each of the fibers as its contacted area moves over its inflicted flaw.
