    Abstract: A fiber cleaver having a displaceable fiber guide for aligning and guiding an optical fiber. Generally, the fiber cleaver includes a pair of clamps that may articulate between a retracted position and a clamping position. A displaceable fiber guide directs the optical fiber as it travels along an internal path of the fiber cleaver. The fiber guide translates between a loading position and a clamping position. When the clamps are securing the optical fiber to the internal path, a linear actuator may be depressed in order to translate the fiber guide and ultimately direct the optical fiber toward a scoring blade to cleave the fiber. The fiber guide is sized and shaped such that a predetermined length of optical fiber will remain after cleaving.

  • Patent number: 9718215
    Abstract: Controllable cleavage of a work piece is achieved through the use of capacitive clamps and application of a large tensile force. Capacitive clamps are used to secure the ends of a work piece with strong electrostatic forces. The capacitive clamps secure the ends of the work piece by creating electrostatic forces like those experienced by the plates in a parallel plate capacitor. After introduction of a crack along a side surface of the work piece, the application of a tensile force along the central axis of the work piece causes the crack to rapidly propagate and cleave the work piece into two or more pieces.

  • Patent number: 9144917
    Abstract: Lengths of an optical fiber may be broken apart from one another while a cross-sectional region of the optical fiber is in a state of multi-axial compressive stress, and the multi-axial compressive stress extends across the optical fiber. The breaking can include propagating a crack across the optical fiber. The crack can be positioned in sufficiently close proximity to the cross-sectional region so that the multi-axial compressive stress restricts the crack from penetrating the cross-sectional region. At least a portion of the optical fiber may be in tension during the breaking.

  • Patent number: 9027815
    Abstract: Apparatus and equipment for making glass sheet from a glass ribbon including scoring, bending and separation in vertical state with improved glass ribbon stability provided by edge restrainers located above the score-line that also travel with substantially the same vertical velocity with the elastic ribbon. The edge restrainers on both sides of the glass ribbon serve to limit the motion and perturbation of the ribbon during scoring, bending and separation, advantageously by tensioning the glass ribbon where needed. The invention can reduce disturbance of the glass ribbon in upstream visco-elastic and/or viscous zones due to scoring, bending and separation, therefore enhance forming process stability and product attributes such as thickness variation, stress and stress variation, and the like. The invention can be particularly advantageous for making glass sheet with large width and/or low thickness using the fusion down-draw, slot down-draw, re-draw down-draw, and other down-draw processes.
