Abstract (en)
[origin: EP0924001A2] The milling works include a cylinder calibration for a cylinder set consisting respectively of three cylinders with a noncircular caliber form. The last calibers of the milling works are locally enlarged at their extent, at which the expected diameter of the ingoing reed is lower than a nominal size, and are locally reduced at their extent, at which the expected diameter of the ingoing reed is larger than a nominal size. The milling works include a cylinder calibration for a cylinder set consisting respectively of three cylinders, having a noncircular caliber form, considering the form change in the cross-section of the reed and working against a noncircular reed outside diameter. The last calibers of the milling works are locally enlarged at their extent, at which the expected diameter of the ingoing reed is lower than a nominal size, and are locally reduced at their extent, at which the expected diameter of the ingoing reed is larger than a nominal size. A manual or automatic measurement of the reed diameter is preferably performed, whose data are stored in a data base for statistic analysis, and are supplied to a CNC machine for a reduction or increase of the theoretic final caliber.
