Abstract
Abstract The invention concerns a monolithic or laminated pane of glass or of plastic materials which contains at least one glass sheet (8, 9). The edge face of the glass sheet is at least partly covered with a protective strip (11, 12) of elastomeric material which has a hardness less than 90 shore A. The protected strip is adhered to the edge face. The strip serves to protect the sheet from any shock or impact it receives during processing prior to assembly into a pane for use in aircraft or transportation vehicles.
