  • Patent number: 8069691
    Abstract: A method of cleaving an optical fiber and apparatus therefor including a hand tool wherein the optical fiber to be cleaved (6) has a natural path. The method of cleaving includes deflecting the optical fiber (6) away from its natural path in a first direction and at a point spaced longitudinal along the length of the fiber deflecting the optical fiber in a second direction opposed to the first direction. The opposing deflection induce internal stresses in the fiber that extend substantially across the core of the optical fiber over a region of the length of the optical fiber. The fiber may then be scratched in this region with a cleaving blade (5) so as to induce cleaving of the optical fiber. The cleaving is controlled by controlling the internal stresses induced in the fiber by in turn controlling the degree of deflection induced in the fiber. Further the fiber (6) may be placed under extension to assist in the control of the stresses induced.

    Abstract: A method for producing glass plates of any desired contour from sheet glass, comprising the following steps: scribing scribe lines into a least one face of the sheet glass along the contour down to a depth, using a cutting device, and positioning the glass plate on a support. The method is further characterized in that a defined force F is applied to the sheet glass so that it breaks along the scribe lines, said break extending through the entire thickness of the sheet glass. The flat glass may be sandwiched between two flexible plates prior to being placed on a base pad and being subjected to the breaking force.

  • Patent number: 7275672
    Abstract: A dispenser for dispensing flexible web material from a center pull roll capable of accommodating different types of web material in the form of sheets separated by lines of perforation. The dispenser includes dispenser apparatus permitting the device to self-adjust to the different thicknesses, sizes and physical characteristics of different types of web material. In certain preferred embodiments, the dispenser comprises a housing, a web support within the housing and structure permitting the dispenser to self-adjust to the effective cross-sectional area of the web. The preferred dispenser structure includes elements positioned to receive the web between them. At least one of the elements is movable and is biased for displacement toward the other. Frictional force applied against the web by the elements resists pull force applied to the web by a user so that a single web sheet separates from the web along the perforation between the elements and the lead end when a user pulls on the web outside the housing.

  • Patent number: 7255253
    Abstract: A method of dividing glass plates for the purpose of reducing the required space in an interim buffer (80) reducing the transit times of different kinds of glasses, comprises generating a sequence of sub-plates (T) from the glass plates (P) stored in a blank plate storage (12), the consecutive sub-plates (T) of the sequence of sub-plates exhibiting identical or different material properties. Each sub-plate (T) is subdivided further by scribing and breaking-off until a desired cut piece has been attained. The generated cut pieces are deposited in a predetermined order in the interim buffer (80) and as called for are processed further. Equipment dividing glass plates into cut pieces accordingly entails that different cutting and breaking-off systems are preceded by at least one intermediate storage receiving at least two glass plates exhibiting different material properties and delivering a programmed sequence of sub-plates, the consecutive sub-plates exhibiting identical or different material properties.

  • Patent number: 7207250
    Abstract: In a system for cutting glass sheets into shapes there is at least one cutting site (A, B). In order to align the glass sheet which is to be cut or the glass sheet shape into a defined position, on the edge of the tables I and II there are contact edges (21, 44, 45). In order to move the glass sheets and the glass sheet shapes into contact with the contact edges (21, 44, 45) the tables I, II are aligned sloping down toward the contact edges (21, 44, 45) so that the glass sheets and glass sheet shapes slide on air cushions produced between the glass sheets or glass sheet shapes and the tables (I, II) in contact with the contact edges (21, 44, 45). The glass sheets or glass sheet shapes which adjoin the contact edges (21, 45) are coupled by force-fit to the conveyor belts (20) which are provided in the area of the contact edges (21, 45) and then moved to the cutting site (A, B) which is located following the table (I, II).

  • Patent number: 7204400
    Abstract: A method and apparatus for separating glass panels that minimizes process failures and improves separation process consistency by utilizing a separation handle which applies the minimal pressure necessary to remove the edge portion from the glass panel. The glass panel is cut along the score line, which outlines the edge portions of the glass panel to be removed. The panel is placed upon the separating apparatus, which pumps nitrogen along the underside of the glass panel, causing the glass panel to float above the apparatus. Locating pins are inserted to position the panel on the stage. Once the glass panel is in place, a vacuum sucks the panel against the stage, holding the panel tightly against the stage. The separation handle is then inserted over the edge portion to be removed. A measured force is applied to the handle, with the force incrementally increased until the slow, controllable separation of the edge is achieved. This level of force is maintained until separation is complete.
