Method For Processing An Edge Of A Glass Plate

View page
US Patent:
2011002, Jan 27, 2011
Filed:
Jul 24, 2009
Appl. No.:
12/508762
Inventors:
James W. Brown - Painted Post NY,
Tadashi Kitamura - Hamamatsu-shi,
Gautam N. Kudva - Horseheads NY,
Siva Venkatachalam - Painted Post NY,
International Classification:
B24B 9/10
B24B 1/00
US Classification:
451 44, 451 57, 451261, 451388
Abstract:
A method for beveling a thin glass plate by simultaneously grinding an edge of the glass using multiple abrasive cup wheels, wherein the edge of the glass plate is extended from the fixturing device. The extension of the glass plate allows the glass plate to bend in response to forces applied by the abrasive cup wheels, thereby reducing the sensitivity of the grinding process to variations in position of the abrasive wheels. The axes of rotation of the abrasive wheels are separated by a distance selected to prevent deflection in the glass plate caused by a first abrasive wheel to influence the deflection in the glass plate caused by a second (adjacent) abrasive wheel.

Mechanical Scoring And Separation Of Strengthened Glass

View page
US Patent:
2011022, Sep 22, 2011
Filed:
Mar 17, 2011
Appl. No.:
13/050281
Inventors:
John Frederick Bayne - Elmira NY,
James William Brown - Painted Post NY,
Siva Venkatachalam - Painted Post NY,
Sujanto Widjaja - Corning NY,
International Classification:
B26F 3/00
B26D 3/08
US Classification:
225 2, 83880
Abstract:
A strengthened glass sheet is separated into undamaged sheet segments by mechanically scribing one or more vent lines of controlled depth into the sheet surface, the depths of the scribed lines being insufficient to effect sheet separation, and then applying a uniform bending moment across the vent lines to effect separation into multiple sheet segments, the vent lines being scribed from crack initiation sites comprising surface indentations formed proximate to the edges of the glass sheet.

Glass Edge Finish System, Belt Assembly, And Method For Using Same

View page
US Patent:
2012015, Jun 21, 2012
Filed:
Dec 15, 2010
Appl. No.:
12/968586
Inventors:
James W. Brown - Painted Post NY,
Jerome T. Firlik - Horse heads NY,
Siva Venkatachalam - Painted Post NY,
Liming Wang - Painted Post NY,
Naiyue Zhou - Painted Post NY,
International Classification:
B24B 1/00
B24B 21/18
US Classification:
451 44, 451296
Abstract:
A glass edge finishing system, a belt assembly and a method are described herein for finishing an edge of a glass sheet. The glass edge finishing system comprises: (a) a base; and (b) one or more belt assemblies located on the base, where each belt assembly includes: (i) a support frame; (ii) a motor; (iii) a pair of pulleys rotatably mounted on the support frame and driven by the motor; (iv) a belt engaged to and driven by the pair of pulleys, where the belt contacts and finishes the edge of the glass sheet; (v) a belt cleaning device that removes glass debris from the belt as the belt moves past the belt cleaning device; and (vi) a cleaning containment enclosure within which there is located the belt cleaning device, where the cleaning containment enclosure contains the glass debris removed from the belt by the belt cleaning device.

Glass Edge Finishing Method

US Patent:
2013000, Jan 3, 2013
Filed:
Jun 28, 2011
Appl. No.:
13/170728
Inventors:
James William Brown - Painted Post NY,
Siva Venkatachalam - Painted Post NY,
International Classification:
B24B 1/00
US Classification:
451 44
Abstract:
A method for finishing an edge of a glass sheet comprising a first grinding step and a second polishing step using different abrasive wheels. The method results in consistent finished edge quality and improved edge quality in term of sub-surface damage (SSD). The method can be advantageously utilized to finish the edges of a thin glass substrate for use as substrates of display devices, such as LCD displays and the like.

Glass Treatment Apparatus And Methods Of Treating Glass

View page
US Patent:
2013013, May 23, 2013
Filed:
Nov 21, 2011
Appl. No.:
13/300921
Inventors:
James William Brown - Painted Post NY,
Keith Mitchell Hill - Horseheads NY,
Siva Venkatachalam - Painted Post NY,
Edward Zhmayev - Ithaca NY,
Naiyue Zhou - Painted Post NY,
International Classification:
B24B 1/00
B08B 3/02
B24B 55/12
B24B 9/10
B24B 53/00
US Classification:
451 44, 451 73, 451178, 451444, 451 54, 451 56, 134151
Abstract:
A glass treatment apparatus, in one example, can include a fluid dispensing device configured to dispense a substantially laminar flow of a fluid film. In another example, a shroud substantially circumscribes an outer peripheral surface of a working wheel. The shroud includes a slot configured to receive an edge portion of a glass sheet. Methods of treating glass, in one example, include the step of dispensing a substantially laminar flow of a fluid film along a fluid plane to subsequently land on a first side of a glass sheet. In further examples, a fluid is passed over an inner surface of a shroud to carry away machined particles from a glass sheet. In still further examples, an outer peripheral surface of a working wheel is impacted with a fluid stream to clean the working wheel from glass particles generated when machining an edge of the glass sheet.

Mechanical Scoring And Separation Of Strengthened Glass

US Patent:
2013029, Nov 7, 2013
Filed:
Jul 3, 2013
Appl. No.:
13/935085
Inventors:
James William Brown - Painted Post NY,
Siva Venkatachalam - Painted Post NY,
Sujanto Widjaja - Cupertino CA,
International Classification:
C03B 33/02
B26D 3/08
US Classification:
225 2, 83880
Abstract:
A strengthened glass sheet is separated into undamaged sheet segments by mechanically scribing one or more vent lines of controlled depth into the sheet surface, the depths of the scribed lines being insufficient to effect sheet separation, and then applying a uniform bending moment across the vent lines to effect separation into multiple sheet segments, the vent lines being scribed from crack initiation sites comprising surface indentations formed proximate to the edges of the glass sheet.

Glass Sheets And Methods Of Shaping Glass Sheets

View page
US Patent:
2014006, Mar 6, 2014
Filed:
Aug 30, 2012
Appl. No.:
13/599090
Inventors:
Siva Venkatachalam - Painted Post NY,
Liming Wang - Painted Post NY,
International Classification:
B24B 9/10
B32B 3/02
US Classification:
428192, 451 44
Abstract:
Methods of shaping a glass sheet each include a step of removing a first portion of the glass sheet to form a first beveled surface. The methods further include the step of removing a second portion of the glass sheet to form a second beveled surface. The methods still further include the step of removing a third portion of the glass sheet comprising a remainder of an end surface of an edge portion of the glass sheet. In further examples, glass sheets are also provided with a first bevel surface intersecting a first glass-sheet surface and an apex surface, and a second bevel surface intersecting a second glass-sheet surface and the apex surface. The glass sheet exhibits a probability of failure of less than 5% at an edge stress of 135 MPa.
