  • Patent number: 10464149
    Abstract: A feed sensor detects location of a wood log to be moved with a feed mechanism in relation to a predetermined point in a device. A control circuit controls a feed mechanism to feed the log for a preset length on the basis of the location of the log detected by the feed sensor. The control circuit controls the cutting mechanism to cut a wood block from a log longer than the predetermined length when the feed mechanism has fed the log for the preset length and a splitting mechanism to split the wood block cut from the log.

  • Patent number: 10407336
    Abstract: A method for cutting a thin glass including the steps of guiding, by a transport device, the thin glass ribbon over a levitation support, and directing, within a range of the levitation support, a laser beam onto the thin glass ribbon, which heats up the thin glass ribbon at an impingement point of the laser beam. The method also includes the step of blowing, by a cooling jet generator, a cooling fluid onto the track heated by the laser beam so that a region heated by the laser beam is cooled down and a mechanical stress is created. The cooling fluid contains vapor of a liquid at a saturation ratio of at least 0.5 or a plurality of liquid droplets. The liquid droplets form a contact angle on a surface of the thin glass ribbon which is smaller than that of water on the same surface.

    Abstract: The method serves for the production of a wire strip (1) comprising a plurality of wires (2) arranged parallel to each other. For this purpose a metal strip is first pre-notched either on one side or both sides for the formation of the wires (2), whereby wires (2) are generated which are still connected to webs (3). To transform the webs (3) subsequently into thin, easy to separate and, when separated, smooth and burr-free separation webs forming separation areas, the wire strip (1) is subjected to a milling process during which each web (3) is subjected to a multiple bending strain along the longitudinal axis thereof in such a way that incipient cracks form, due to fatigue fracture, in the area of the webs (3), and thereby the separation web is created.

  • Patent number: 8740029
    Abstract: Axial tension is applied to an optical fiber that had been scored at the intended cleave location, wherein the axial tension is applied in a time-varying manner to maintain the stress intensity factor for crack on the fiber within an acceptable level to produce a stable crack growth at a reasonable rate to cleave the fiber without requiring polishing of the end surface. Careful control of the applied tension force with time acts to control the velocity of the propagating crack by maintaining substantially constant stress intensity factor. The applied axial tension force is reduced with time and/or crack growth (as crack propagates). As a result, the strain energy in the fiber material is released by formation of a single plane with an optical quality surface without requiring polishing. A substantially flat optical surface of enhanced optical quality is formed at the cleaved end of the optical fiber.

The initial flaw is turned into a crack that propagates continuously throughout the processing of the ribbon. The cracking itself results in no material loss. After cracking, the cut side edge is routed along a path different than the interior quality region to avoid contact damage between the quality region and the edge portion. The quality region can be provided for further processing or be stored. The flexible, brittle ribbon can be sourced from a hot forming device or from a roll (spool) of substrate.

  • Patent number: 8292141
    Abstract: A pane is separated from a moving ribbon of brittle material by restraining the ribbon upstream of a score line prior to separating the pane. The ribbon is restrained by selectively contacting a first side and a second side of the ribbon in one of an opposite, overlapping or offset relation. The ribbon can be restrained prior to, substantially simultaneous with or subsequent to forming the score line. The restrained status of the ribbon is maintained during and immediately after separation of the pane from the ribbon, thereby reducing the introduction of a disturbance or bending moment into the upstream ribbon.

  • Patent number: 8261646
    Abstract: Transversal cutting machine comprises feeding means (20) that supply a log of paper (15), for example hygienic paper, to a sawing station at which rolls or stacks (16) are cut off from the log (15) by a blade (25). During the cutting step the log (15) is held by a clamping device (1), divided in two parts (2, 3) arranged respectively upstream from and downstream of a slit (17) through which the blade (25) passes. In particular, the first part (2) and the second part (3) of clamping device (1) are movable relatively so that during the cut the log (15) is locally subject to traction at the same time of the blade (25) driven in the log. This way, during the cutting action of the blade (25) an opening (17) is created on the log (15) having a size at least the same as the thickness of blade (25) same. This makes easier the action of blade (25) since it reduces the friction produced between the blade (25) and the log (15).

It includes a clamp which holds the coated optical fiber, having a glass fiber and the coating, on both sides of a portion-to-be-cut, a disk-shaped blade member which moves at the portion-to-be-cut in a direction orthogonal to an axis of the optical fiber to cut the coating and to provide a slit into the glass fiber, and a support which presses, with a predetermined pressing force, the portion-to-be-cut from an opposite side of the blade member with respect to the portion-to-be-cut when cutting the coating and providing the slit into the glass fiber. A head of the support is formed with a groove along a sliding direction of the blade member.

  • 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.
