A method includes advancing a glass article relative to a fiber; positioning the fiber in relation to an edge of the glass article, contacting a first side of the fiber with a first laser beam, contacting a second side of the fiber with a second laser beam, depositing the fiber on the edge of the glass article, and contacting the edge of the glass article with a third laser beam.
Forming Method for Curved Glass
A forming method for curved glass has been provided. The method comprises: placing a flat glass plate in a pattern die, and placing the pattern die in a forming apparatus; and subjecting the pattern die successively to staged heating, staged forming and staged cooling, so as to obtain the curved glass, wherein the staged heating is performed over stages which are different from each other in temperature, the staged forming is performed over stages which are different from each other in temperature, and during at least one of the stages, a varying pressure which varies from low pressure to high pressure is applied to the pattern die, the staged cooling is performed by cooling the glass plate in the pattern die over stages which are different from each other in temperature. The glass product could be used as front and rear covers of electronic products including notebook computers, mobile phones, tablet computers and smart watches.
MANUFACTURING METHOD FOR LAMINATED GLASS
A manufacturing method for a laminated glass in which a plurality of glass plates are laminated, includes a first main forming step of heating a first glass plate to a first softening point or higher to perform a main forming; a second main forming step of heating a second glass plate to a second softening point or higher to perform the main forming; a first finish forming step of bending and forming the first glass plate into a desired shape; and a second finish forming step of bending and forming the second glass plate into a desired shape. The first and second main forming steps are performed by using a same forming die. A first condition for lowering a temperature of the first glass plate to below the first softening point and a second condition for the second glass plate are different from each other.

A laser treatment device performing treatment by irradiating a target object having a plate surface with laser light, including: a light-transmitting region transmitting laser light emitted onto the target object; a rectifier that has a rectifier surface separated from the target object and extending along the plate surface of the target object and outward from the end of the light-transmitting region; a gas supply unit that feeds a gas to a gap between one side of the rectifier surface and the light-transmitting region, in a position separated from the light-transmitting region; and a gas exhaust unit that exhausts, on the other side that is on the other side of the light-transmitting region from the one side, the gas present in a gap between the rectifier surface and the target object from the gap, in a position separated from the light-transmitting region, thereby generating a stable local gas atmosphere.
Automotive laminate with improved optics
The use of camera based safety systems is growing at a rapid rate in modern automobiles. As the industry moves towards vehicles with full autonomous capability, the number of cameras required and the resolution of the cameras are both increasing. At the same time, windshields, where many of the cameras are mounted, are becoming larger and more complex in shape. This presents problems in the area of camera optics. Variations in the thickness of the glass and the plastic layer, surface mismatch, surface texture and the design curvature of the glass in conjunction with the often low installation angle, can reduce the optical clarity of the camera optics. These optical aberrations are further exacerbated during the lamination process when the layers are bonded together under pressure. The laminate of the invention utilizes a cutout in the plastic bonding layer in side of the laminate, preferable in the camera field of view. A laminating resin is used to fill the gap left by the cutout between the two glass layers.
