Abstract
A method for producing from a plate-shaped substrate circular sections for use for instance in a color wheel encompasses inter alia such steps as positioning predefined edge break lines in such fashion that the circular sections to be separated at a subsequent point are arranged in columns, with the circular sections within a column being so positioned relative to one another that in each case at least certain points of the inner annular edge are in contact with the outer annular edge of another circular section, thus forming part of a common predefined edge break line, while the orientation of the curvature of the circular sections of neighboring columns is reversed in alternating fashion. In a subsequent step the circular sections are separated along the predefined edge break lines.

Method for producing a wheel from circular sections manufactured from a plate-shaped substrate, employing the following steps:
- positioning of predefined edge break lines in a manner whereby in a subsequent operation they serve to separate circular sections in a columnar arrangement,
- wherein within a column the circular sections are so positioned relative to one another that in each case at least certain points of the inner annular edge (7) of a given circular section is in contact with the outer annular edge (5) of another circular section, thus forming a segment of a common predefined edge break line,
- and the orientation of the curvature of the circular sections of neighbouring columns extends in alternating fashion
- and neighbouring columns are interlaced,
- wherein the interlacing is limited to a degree that one or multiple loss areas result,
- breaking the circular sections along the break lines, and
- joining the circular sections along their radial edges into a two-dimensional wheel.
