  • 1 machine-mounted FMT Schonthaler two wheel roll caliper system consisting of:

    • One (1) lot of measuring equipment to measure various geometrical features of rolls reground at the paper mill. The measuring device is designed for, and mounts on an existing Farrel two-wheel roll grinder. The special design features two measuring gauges in brackets/levers mounted on the wheel guards of the roll grinder. The gauges traverse the length of the roll body on the carriage thus being able to measure and record the geometrical characteristics of the roll over its entire length, and at any fixed location but with the roll rotating.

  • The measuring device records, displays and provides a hard copy of the measurement in the form of a graph, representing continuous measurement over the length or circumference of the roll. The graph also displays the nominal or base measurement parameter (a zero-line, cosine crown, or compound crown target) and tolerances. The device provides reports on the following measurement modes:

    • Two gauge straight profile measurement
    • Two gauge crown measurement
    • One gauge concentricity measurement at 3 and 9 o'clock positions
    • Two gauge roundness measurement

  • Special measurements such as sag, roll alignment, machine ways, and T.I.R. in other positions, are possible using the standard modes, too. Resolution of the measuring system is settable to .0005", .0001", .00002", 0,01 mm, 0,001 mm or 0,0005 mm.

    The recording system is PC based with report display and hard copy capabilities. The graph is displayed during measuring (profile and crown) or immediately after (T.I.R. and roundness) a measuring pass. The reports also include entered or previously saved roll data. Ther
