Abstract: The invention is based on the object of improving the detachment of portions of a glass rod to the extent that a very planar, uniform fracture surface is produced. For this purpose, an apparatus according to the invention for detaching portions of glass rods comprises a device for the parallel holding and lateral fixing of a number of glass rods, a scoring wheel holder with a scoring wheel rotatably mounted parallel to the axis of the glass rods, at least one pressing spring for pressing the scoring wheel and the glass rods against one another, a device for guiding the glass rods and the scoring wheel past one another in a direction perpendicular to the axis of the glass rods, a holddown means for pressing against the glass rods, a breaking bar and a breaking beam, the breaking bar being arranged opposite, between the holddown means and the breaking beam.
