Abstract

PURPOSE: To make it possible to measure the accurate running distance in a non- contact manner by converting the shading of the surface of a running test piece into ON-OFF electric signals of n bits by means of an optical sensor which is arranged in parallel with the running direction.
CONSTITUTION: In case it is intended to measure the sheet insertion of a single facer of a currugate machine, the optical sensor of a deive A is arranged in the running direction of the sheet so that the optical shading of the sheet surface is converted into ON-OFF electric signals of n bits, which are stored. After a preset time lear, the shading of the sheet surface is converted into ON-OFF signals of n bits. By metering the discrepancy in phase of the electric signals of those two types, the moving distance of the sheet during a preset time can be measured.
