Method for producing a system for securing a glass pane comprising two opposite, flat, plane-parallel outer surfaces (10', 10") by means of a sash manufactured from a wooden block, wherein the glass pane, in the assembled state, rests on the sash in a plane perpendicular to its plane-parallel outer surfaces (10', 10"), and by means of a glass retaining strip which abuts one of the outer surfaces (10', 10") in the assembled state of the system, which strip is manufactured together with the sash from the same block, the production comprising the following steps: a) providing the block made of wood; b) calibrating the block by planing it to a calibration thickness D K which corresponds to the exact later height of a structure consisting of the sash and the glass retaining strip in the assembled state, optionally plus the thickness d T of a horizontal separating cut, if the sash and the glass retaining strip are separated during the manufacturing in step f); c) internally profiling the structure consisting of the sash and the glass retaining strip on the side of the sash facing the glass pane in the assembled state of the system; d) vertically profiling by means of a vertical separating cut between the sash and the glass retaining strip; e) externally profiling the structure consisting of the sash and the glass retaining strip on the side of the sash facing away from the glass pane in the assembled state; f) carrying out a horizontal separating cut in order to separate the sash and the glass retaining strip in the block machined in steps b) to e); and g) assembling the system by joining the sash and the glass retaining strip together; wherein in manufacturing step b) the block is only calibrated to the exact later height of the structure consisting of the sash and the glass retaining strip in the assembled state, wherein the thickness d T of the horizontal separating cut in manufacturing step f) is not added to the calibration thickness; wherein, before joining the sash and the glass retaining strip together in assembly step g), the glass retaining strip which has been manufactured and completely separated from the sash in step f) is rotated by 180° relative to the sash about a vertical axis of rotation; and wherein the glass retaining strip is mounted relative to the sash in assembly step g) such that the glass retaining strip, in the assembled state of the system, abuts the bottom surface (11") of the sash with a surface (12"), but does not abut the cut surface of the sash which is generated during the horizontal separating cut in manufacturing step f) with its cut surface which was generated simultaneously by the horizontal separating cut in manufacturing step f). a) providing the block made of wood; b) calibrating the block by planing it to a calibration thickness D K which corresponds to the exact later height of a structure consisting of the sash and the glass retaining strip in the assembled state, optionally plus the thickness d T of a horizontal separating cut, if the sash and the glass retaining strip are separated during the manufacturing in step f); c) internally profiling the structure consisting of the sash and the glass retaining strip on the side of the sash facing the glass pane in the assembled state of the system; d) vertically profiling by means of a vertical separating cut between the sash and the glass retaining strip; e) externally profiling the structure consisting of the sash and the glass retaining strip on the side of the sash facing away from the glass pane in the assembled state; f) carrying out a horizontal separating cut in order to separate the sash and the glass retaining strip in the block machined in steps b) to e); and g) assembling the system by joining the sash and the glass retaining strip together;
