Use a text editor to view the data base in file FLUTE.BSE. The default Table of Flute Profiles is shown below. Default geometries for A-, B-, and C-flute profiles were chosen from published literature. The recommended method for specifying flute geometry is to measure the dimensions shown in figure 9 that characterize the corrugating rolls. The geometry of the combined board shown in figure 4 results from flute geometry, linerboard caliper, and medium caliper.

The interference between the core and facing geometry shown in figure 4 is a function of the flute profile and yields the widths of the fiberboard microplate elements. The default interference between the core and single face surface is considered to be what results from the neutral position (figure 9). The interference can be increased or decreased from the default dimension by specifying data in column 7.

When the corrugator combines the corrugated medium and double back linerboard the flute tip is flattened and adhesive is distributed over a small area. The effect of contact area on microplate width is dealt with by defining an effective double back interference as a multiple of the single face interference. Specifying data in column 8 will change the multiple from the default multiple given in the subtitle block.
