ABSTRACT:
An instrument for sensing the profile of an elongate tooth of a corrugation roll or gear wheel or the like. A carriage supports an axially movable stem which is operably connected to an indicator element. The stem has an engagement portion which engages a tooth of a corrugation roll as the carriage is moved along the roll. The carriage is provided with runners or slide elements which travel within troughs or valleys, which separate the teeth of the corrugation roll. Preferably, a magnet member is attached to the carriage and is positioned adjacent the surface of the corrugation roll and maintains the position of the carriage with respect to the roll as the carriage is moved along the roll.
