ABSTRACT:
The method comprises the steps of (a) inflicting a flaw on the glass surface of an optical glass fiber to be severed, (b) contacting an area about the fiber for applying pressure thereto which compresses the fiber, and (c) moving the contacted area along the fiber while applying sufficient pressure to produce frictional force which severs the fiber as the contacted area moves over the flaw. The means of the invention comprises scoring means for inflicting a flaw on the glass surface of an optical glass fiber to provide the fiber with first and second portions which are axially displaced to border the flaw on opposite sides, pressure means which slidably engages and compresses the fiber by applying pressure to a contacted area about the fiber, and displaceable means which applies tension force between the first portion of the fiber and the pressure means to move the fiber with respect to the pressure means so that its contacted area passes over the inflicted flaw on the glass surface as it moves along the fiber from its first portion to its second portion. The pressure means produces frictional force with the motion of the fiber at the contacted area along the surface of the fiber in a direction opposing the motion, which force increases on the second portion of the fiber until it is sufficient to sever the fiber at the inflicted flaw.
