Abstract:
A glass ribbon (10) including a first glass-ribbon portion (12) and a second portion (22) separated from one another by a gap (40), and a splice joint (30) coupling the first glass-ribbon portion to the second portion. The splice joint includes a splice member (31) having a Young's modulus and cross sectional area so that when subject to a force of 20kg the splice member undergoes an elongation of = 20%. A filler material (80) may be disposed in the gap. Also, there are disclosed methods of splicing a glass ribbon, and preparing a coated glass ribbon for splicing. One embodiment of a method of splicing glass ribbon includes applying tape (70) to the glass ribbon, and cutting the glass ribbon together with the tape so as to create a free end in the glass ribbon. Before the glass ribbon is cut, a fracture line (75, 77) may be created in the glass ribbon wherein the tape is disposed across the fracture line. When preparing a coated glass ribbon, a separate tape member need not be applied before creating the fracture line or cutting the glass ribbon.
Abstract:
The invention relates to a method for the continuous or continuous-discontinuous production of foam glass plates, wherein the foam glass is foamed to produce a foamed glass web (16) from at least one raw glass material and at least one blowing agent in a foaming oven and is continuously annealed in an annealing oven (5) or discontinuously annealed in annealing boxes. Said foamed glass web is transported through the oven(s) on a continuous conveyor system during foaming and annealing and said foamed glass web is cut in the hot state in the oven or between two ovens. The invention also relates to a corresponding cutting device and to a foamed glass annealing path provided with a corresponding cutting device.
Abstract:
Laser scoring of a glass ribbon (13) which moves at a non-constant speed is performed using a tilted track (15) and a carriage (14) which travels down the track. The carriage can include a flying optical head (51) which receives laser light from a flexible laser beam delivery system (61) coupled to a laser (41). Variations in the speed of the ribbon which are less than or equal to ±3% of the ribbon's nominal speed can be accommodated by varying the speed of the carriage and adjusting the output power of the laser (41). Greater speed variations can additionally involve adjusting the tilt angle α the track. Adjustments of the orientation of a first lens unit (53) within the flying optical head (51) can be made to maintain the major axis of the laser beam along the score line as the tilt angle is changed.
Abstract:
Die vorliegende Erfindung betrifft ein Verfahren zur kontinuierlichen oder kontinuierlichdiskontinuierlichen Herstellung von Schaumglasplatten, bei dem das Schaumglas aus mindestens einem Glasrohstoff und mindestens einem Blähmittel in einem Schäumofen zu einem Schaumglasstrang (16) aufgeschäumt und in einem Abkühlofen (5) kontinuierlich oder in Abkühlboxen diskontinuierlich abgekühlt wird, wobei der Schaumglasstrang während des Aufschäumens und Abkühlens auf einer kontinuierlichen Förderanlage durch den oder die Öfen transportiert wird, und wobei der Schaumglasstrang im heißen Zustand im Ofen oder zwischen zwei Öfen geschnitten wird sowie eine entsprechende Schneidvorrichtung und eine Schaumglaskühlstrecke mit einer entsprechenden Schneidvorrichtung.
Abstract:
A method for separating sheet of brittle material having a thickness equal to or less than about 1 mm is disclosed. Once an initial flaw or crack is produced, a full body crack can be propagated across a dimension of the brittle material with a laser beam that is substantially absorbed proximate the surface of the sheet to produce sub-sheets. In some embodiments, only a single pass of the laser beam over a surface of the sheet is necessary to separate the sheet. In other embodiments a plurality of passes may be used. Sub-sheets can be further processed into electronic devices by depositing thin film materials on the sub-piece.
Abstract:
A scoreless separation device and method are described herein for separating a glass sheet without needing to score the glass sheet. In one embodiment, the device shears a stationary glass sheet without needing to score the glass sheet. In another embodiment, the device shears a moving glass sheet to remove outer edges from the moving glass sheet without needing to score the moving glass sheet.
