Abstract
Apparatus for automatically loosening the marginal strip from a sheet of contour-cut glass with a minimum of edge defects comprises, in substance, a horizontal conveyor; a tracing assembly of cutting tools disposed above the conveyor for marking off auxiliary cutouts subdividing the marginal strip; and separation means comprising pressing tools for pressing the sheet in such a manner as to apply a bending moment along the auxiliary cutouts. The pressing tools are arranged opposite the margins both on their upper face and their lower face, and they bear on either side of the auxiliary cutout lines in order to exert bending moments along each. As a consequence, the apparatus generates a progressive breaking stress whereby separation of the margins is effected starting from an area external of the actual contour cutout line before spreading along the contour. The result is a particularly clear-cut edge.
