Disclosed is a method for producing annulus sections, e.g. for a color wheel, from a plate-shaped substrate. Said method comprises the following steps, among others: setpoint braking edges are disposed such that the annulus sections that are to be separated later on are disposed in columns, the annulus sections within a column being arranged in relation to each other in such a way that the inner arc edge of one annulus section touches the outer arc edge of another arc section at least at some points, thus forming a stretch of a joint setpoint breaking edge, the curve of the annulus sections of adjacent columns being oriented in an alternating fashion. In another step, the annulus sections are separated along the setpoint breaking edges. |
