Abstract

Panes employed in mfg. bent multilayer safety glass are cut to their different peripheral shapes prior to assembly and bending to form one pane. The novelty is that the panes (e.g. two) are simultaneously cut to their respective sizes using separate cutting tools. The pref. cutting plant uses only one template scanned by an x-y coordinate controller driving two slides, each fitted with a cutter. The first slide cuts one pane to the size of the template, but the second slide is fitted with two servomotors programmed so the second pane is cut to a larger size. The second pane has a larger bending radius so that after assembly and bending both are the same length and form one pane of safety glass.
