Process for breaking out an inner shape in a glass sheet

A process for breaking out an inner shape in a glass sheet intended to form a glazing, comprising:

• scoring a cutting line in a surface of the glass sheet using a cutting tool, which cutting line delimits an outer contour of said inner shape and an 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;
• deforming, with a deformation system, one of the inner shape and of the peripheral shape by convex bending of said one of the inner shape and of the peripheral shape toward a side opposite the cutting line, said convex bending creating a differential deformation between the inner shape and the peripheral shape that is sufficient to break out the inner shape along the cutting line and separate the inner shape from the peripheral shape so that a distance needed for a contactless extraction of the inner shape relative to the peripheral shape is created, and
• after separating the inner shape from the outer shape, maintaining the convex bending of said one of the inner shape and of the peripheral shape and extracting the inner shape relative to the peripheral shape by moving the inner shape relative to the peripheral shape while maintaining the convex bending to carry out a contactless extraction of the inner shape from the outer shape.
