摘要： A thermal edge-finishing process includes pre-heating an edge of a glass sheet, focused heating inboard of the edge to cause thermal tensioning, laser finishing the edge, and localized annealing of the edge. By stress cancellation, the thermal energy added by a laser edge-finishing operation does not result in as much residual stress. By the present process, residual stress is reduced to below 3000 psi, and more preferably to about 1000 psi, and as low as 600 psi in the first 1 mm along the treated edge.

摘要： Apparatus and equipment for making glass sheet from a glass ribbon including scoring, bending and separation in vertical state with improved glass ribbon stability provided by edge restrainers located above the score-line that also travel with substantially the same vertical velocity with the elastic ribbon. The edge restrainers on both sides of the glass ribbon serve to limit the motion and perturbation of the ribbon during scoring, bending and separation, advantageously by tensioning the glass ribbon where needed. The invention can reduce disturbance of the glass ribbon in upstream visco-elastic and/or viscous zones due to scoring, bending and separation, therefore enhance forming process stability and product attributes such as thickness variation, stress and stress variation, and the like. The invention can be particularly advantageous for making glass sheet with large width and/or low thickness using the fusion down-draw, slot down-draw, re-draw down-draw, and other down-draw processes.
摘要翻译：用于从玻璃带制造玻璃板的设备和设备，其包括在垂直状态下的刻划，弯曲和分离，并且由位于分数线之上的边缘限制器提供改进的玻璃带稳定性，其也以与弹性带基本上相同的垂直速度行进。玻璃带两侧的边缘限制器有利于通过在需要时张紧玻璃带来限制色带在打样，弯曲和分离期间的运动和扰动。本发明可以减轻由于刻痕，弯曲和分离而导致的上游粘弹性和/或粘性区域中的玻璃带的干扰，从而增强成形工艺的稳定性和产品属性，例如厚度变化，应力和应力变化等。本发明可以特别有利于制造具有大的宽度和/或低厚度的玻璃板，其中使用熔融拉伸，槽下拉，再拉伸和其它下拉法。

摘要： A method of separating a moving glass ribbon to form an individual sheet of glass is disclosed comprising a plurality of nosing members that move in a direction and at a speed that the moving glass ribbon is moving. The nosing members can be positioned independently of each other, and can be positioned adjacent to but not in contact with the ribbon during the scoring operation to restrict out-of-plane movement of the glass ribbon (movement substantially transverse to the draw direction of the ribbon) during the separation phase of the process.

摘要： A thermal edge finishing process includes preheating at least one cut edge of a glass sheet, laser finishing the edge to a single full continuous radius from a position orthogonal to the edge and in-plane with the glass sheet while continuing to heat the glass, and localized annealing of the edge to reduce residual stress from the laser/thermal treatment of the edge. By the present process, edge stress is reduced considerably, such as to less than 3000 psi, and more preferably to less than 2500 psi, and to as low as 1000 psi in the first 1 mm along the treated edge.

摘要： Methods and apparatuses for managing pulling forces applied to a glass ribbon in a draw apparatus are disclosed. The method includes applying a front-side and a rear-side drive torque to a glass. The method further includes calculating automatically with the at least one electronic controller a front-side and a rear-side average pulling force applied to the glass ribbon and corresponding to a first time period of at least one rotation of the front-side or rear-side stub roller, respectively. The front-side average pulling force and the rear-side average pulling force are compared to establish a pulling force differential between the front-side average pulling force and the rear-side average pulling force. One or more of the front-side drive torque or the rear-side drive torque are modified to decrease the pulling force differential between the front-side average pulling force and the rear-side average pulling force.
