SHEET SEPARATION THROUGH FLUID IMPACT

摘要

A sheet of brittle material, such as glass, flat or bowed, is separated along a score line by applying fluid energy (compressed gas or liquid) through a fluid applicator such as a nozzle or directional fluid motivator, into a scored sheet material. A separation time of less than 1 second is possible with smooth edge quality. The brittle material can be in the form of a moving ribbon of glass sheet or a stationary sheet. A load (tension) can be applied transverse to the score line to enhance crack propagation along the score line. A controller controls the fluid pressure, release time and other process parameters for best results, depending on material properties and structure.
