Abstract
A break-out process includes scoring a cutting line in the surface of the glass using a cutting tool, which cutting line delimits the outer contour of the inner shape and the inner contour of a peripheral shape; bringing the peripheral shape of the glass sheet into contact with a bearing system along the outer contour of the inner shape; the use of a deformation system for deforming one of the inner shape and of the peripheral shape by convex bending toward the side opposite the cutting line. The differential deformation between the inner shape and the peripheral shape is sufficient to break out the inner shape along the cutting line and create the distance needed for the contactless extraction of the inner shape relative to the peripheral shape. The extraction is carried out while maintaining the convex bending.
