Pressure Blanking of Sheet Glass

概要

論文の詳細を見る
A new blanking method for sheet glass is presented in this paper. Blanking is easily accomplished by pressing sheet glass under high pressure between very stiff anvils of the same shape and size. In pressing, the sheet glass between the anvils remains uncracked, but the rest is scattered. Sheet glass of the desired shape can, therefore, be made by using the proper anvils. The effects of the experimental conditions upon crack propagation in the sheet are investigated, and the conditions required for the blanking are also clarified. Sheet glass of various shapes is then made in a practical manner using this method, referred to here as "pressure blanking".
